ADDENDUM
This addendum contains information that relates to the T60 Transformer Protection System, version 6.0x. This adden-
dum lists a number of information items that appear in the instruction manual GEK-113591 (revision X1) but are not
included in the current T60 operations.
The following functions and items are not yet available with the current version of the T60 relay:
• Signal sources SRC 5 and SRC 6.
Version 4.0x and higher releases of the T60 relay includes new hardware (CPU and CT/VT modules).
• The new CPU modules are specified with the following order codes: 9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, 9R, and 9S.
• The new CT/VT modules are specified with the following order codes: 8F, 8G, 8H, 8J 8L, 8M, 8N, 8R.
The following table maps the relationship between the old CPU and CT/VT modules to the newer versions:
The new CT/VT modules can only be used with the new CPUs (9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, 9R, and 9S), and
the old CT/VT modules can only be used with the old CPU modules (9A, 9C, 9D). To prevent any hardware mis-
matches, the new CPU and CT/VT modules have blue labels and a warning sticker stating “Attn.: Ensure CPU and
DSP module label colors are the same!”. In the event that there is a mismatch between the CPU and CT/VT module,
the relay will not function and a DSP ERROR or HARDWARE MISMATCH error will be displayed.
All other input/output modules are compatible with the new hardware.
With respect to the firmware, firmware versions 4.0x and higher are only compatible with the new CPU and CT/VT mod-

1 Historically, substation protection, control, and metering functions were performed with electromechanical equipment. This
first generation of equipment was gradually replaced by analog electronic equipment, most of which emulated the single-
function approach of their electromechanical precursors. Both of these technologies required expensive cabling and auxil-
iary equipment to produce functioning systems.
Recently, digital electronic equipment has begun to provide protection, control, and metering functions. Initially, this equip-
ment was either single function or had very limited multi-function capability, and did not significantly reduce the cabling and
auxiliary equipment required. However, recent digital relays have become quite multi-functional, reducing cabling and aux-
iliaries significantly. These devices also transfer data to central control facilities and Human Machine Interfaces using elec-
tronic communications. The functions performed by these products have become so broad that many users now prefer the
term IED (Intelligent Electronic Device).
It is obvious to station designers that the amount of cabling and auxiliary equipment installed in stations can be even further
reduced, to 20% to 70% of the levels common in 1990, to achieve large cost reductions. This requires placing even more
functions within the IEDs.
Users of power equipment are also interested in reducing cost by improving power quality and personnel productivity, and
as always, in increasing system reliability and efficiency. These objectives are realized through software which is used to
perform functions at both the station and supervisory levels. The use of these systems is growing rapidly.
High speed communications are required to meet the data transfer rates required by modern automatic control and moni-
toring systems. In the near future, very high speed communications will be required to perform protection signaling with a
performance target response time for a command signal between two IEDs, from transmission to reception, of less than 3
milliseconds. This has been established by the IEC 61850 standard.
IEDs with the capabilities outlined above will also provide significantly more power system data than is presently available,
enhance operations and maintenance, and permit the use of adaptive system configuration for protection and control sys-
tems. This new generation of equipment must also be easily incorporated into automation systems, at both the station and
enterprise levels. The GE Multilin Universal Relay (UR) has been developed to meet these goals.
a) UR BASIC DESIGN 1
The UR is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output
signals. The UR can communicate over a local area network (LAN) with an operator interface, a programming device, or
another UR device.
LAN
Programming Operator
Device Interface
827822A2.CDR
b) UR SIGNAL TYPES
The contact inputs and outputs are digital signals associated with connections to hard-wired contacts. Both ‘wet’ and ‘dry’
contacts are supported.
The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include
signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize
the device. Virtual outputs can also serve as virtual inputs to FlexLogic™ equations.
The analog inputs and outputs are signals that are associated with transducers, such as Resistance Temperature Detec-
tors (RTDs).
The CT and VT inputs refer to analog current transformer and voltage transformer signals used to monitor AC power lines.
The UR-series relays support 1 A and 5 A CTs.
The remote inputs and outputs provide a means of sharing digital point state information between remote UR-series
devices. The remote outputs interface to the remote inputs of other UR-series devices. Remote outputs are FlexLogic™
operands inserted into IEC 61850 GSSE and GOOSE messages.
The direct inputs and outputs provide a means of sharing digital point states between a number of UR-series IEDs over a
dedicated fiber (single or multimode), RS422, or G.703 interface. No switching equipment is required as the IEDs are con-
nected directly in a ring or redundant (dual) ring configuration. This feature is optimized for speed and intended for pilot-
aided schemes, distributed logic applications, or the extension of the input/output capabilities of a single relay chassis.
c) UR SCAN OPERATION
1 The UR-series devices operate in a cyclic scan fashion. The device reads the inputs into an input status table, solves the
logic program (FlexLogic™ equation), and then sets each output to the appropriate state in an output status table. Any
resulting task execution is priority interrupt-driven.

The firmware (software embedded in the relay) is designed in functional modules which can be installed in any relay as
required. This is achieved with object-oriented design and programming (OOD/OOP) techniques.
Object-oriented techniques involve the use of objects and classes. An object is defined as “a logical entity that contains
both data and code that manipulates that data”. A class is the generalized form of similar objects. By using this concept,
one can create a protection class with the protection elements as objects of the class, such as time overcurrent, instanta-
neous overcurrent, current differential, undervoltage, overvoltage, underfrequency, and distance. These objects represent
completely self-contained software modules. The same object-class concept can be used for metering, input/output control,
hmi, communications, or any functional entity in the system.
Employing OOD/OOP in the software architecture of the T60 achieves the same features as the hardware architecture:
modularity, scalability, and flexibility. The application software for any UR-series device (for example, feeder protection,
transformer protection, distance protection) is constructed by combining objects from the various functionality classes. This
results in a common look and feel across the entire family of UR-series platform-based applications.
As described above, the architecture of the UR-series relays differ from previous devices. To achieve a general understand-
ing of this device, some sections of Chapter 5 are quite helpful. The most important functions of the relay are contained in
“elements”. A description of the UR-series elements can be found in the Introduction to elements section in chapter 5.
Examples of simple elements, and some of the organization of this manual, can be found in the Control elements section of
chapter 5. An explanation of the use of inputs from CTs and VTs is in the Introduction to AC sources section in chapter 5. A
description of how digital signals are used and routed within the relay is contained in the Introduction to FlexLogic™ section
in chapter 5.
The faceplate keypad and display or the EnerVista UR Setup software interface can be used to communicate with the relay.

NOTE
1 Please refer to Chapter 3: Hardware for detailed mounting and wiring instructions. Review all WARNINGS and CAUTIONS
carefully.
1.4.2 COMMUNICATIONS
The EnerVista UR Setup software communicates to the relay via the faceplate RS232 port or the rear panel RS485 / Ether-
net ports. To communicate via the faceplate RS232 port, a standard straight-through serial cable is used. The DB-9 male
end is connected to the relay and the DB-9 or DB-25 female end is connected to the PC COM1 or COM2 port as described
in the CPU communications ports section of chapter 3.
All messages are displayed on a 2 20 backlit liquid crystal display (LCD) to make them visible under poor lighting condi-
tions. Messages are descriptive and should not require the aid of an instruction manual for deciphering. While the keypad
and display are not actively being used, the display will default to user-defined messages. Any high priority event driven
message will automatically override the default message and appear on the display.
Display messages are organized into pages under the following headings: actual values, settings, commands, and targets.
1
The MENU key navigates through these pages. Each heading page is broken down further into logical subgroups.
The MESSAGE keys navigate through the subgroups. The VALUE keys scroll increment or decrement numerical setting
values when in programming mode. These keys also scroll through alphanumeric values in the text edit mode. Alterna-
tively, values may also be entered with the numeric keypad.
The decimal key initiates and advance to the next character in text edit mode or enters a decimal point. The HELP key may
be pressed at any time for context sensitive help messages. The ENTER key stores altered setting values.
Press the MENU key to select the desired header display page (top-level menu). The header title appears momentarily fol-
lowed by a header display page menu item. Each press of the MENU key advances through the following main heading
pages:
• Actual values.
• Settings.
• Commands.
• Targets.
• User displays (when enabled).
The setting and actual value messages are arranged hierarchically. The header display pages are indicated by double
scroll bar characters (), while sub-header pages are indicated by single scroll bar characters (). The header display
pages represent the highest level of the hierarchy and the sub-header display pages fall below this level. The MESSAGE
UP and DOWN keys move within a group of headers, sub-headers, setting values, or actual values. Continually pressing
the MESSAGE RIGHT key from a header display displays specific information for the header category. Conversely, contin-
ually pressing the MESSAGE LEFT key from a setting value or actual value display returns to the header display.
SETTINGS
SYSTEM SETUP
The relay is defaulted to the “Not Programmed” state when it leaves the factory. This safeguards against the installation of
a relay whose settings have not been entered. When powered up successfully, the Trouble LED will be on and the In Ser-
vice LED off. The relay in the “Not Programmed” state will block signaling of any output relay. These conditions will remain
until the relay is explicitly put in the “Programmed” state.
Select the menu message SETTINGS PRODUCT SETUP INSTALLATION RELAY SETTINGS
RELAY SETTINGS:
Not Programmed
To put the relay in the “Programmed” state, press either of the VALUE keys once and then press ENTER. The faceplate
1 Trouble LED will turn off and the In Service LED will turn on. The settings for the relay can be programmed manually (refer
to Chapter 5) via the faceplate keypad or remotely (refer to the EnerVista UR Setup help file) via the EnerVista UR Setup
software interface.
It is recommended that passwords be set up for each security level and assigned to specific personnel. There are two user
password security access levels, COMMAND and SETTING:
1. COMMAND
The COMMAND access level restricts the user from making any settings changes, but allows the user to perform the fol-
lowing operations:
• change state of virtual inputs
• clear event records
• clear oscillography records
• operate user-programmable pushbuttons
2. SETTING
The SETTING access level allows the user to make any changes to any of the setting values.
Refer to the Changing Settings section in Chapter 4 for complete instructions on setting up security level
passwords.
NOTE
FlexLogic™ equation editing is required for setting up user-defined logic for customizing the relay operations. See the Flex-
Logic™ section in Chapter 5 for additional details.
1.5.7 COMMISSIONING
The T60 Transformer Protection System is a microprocessor-based relay for protection of small, medium, and large three-
phase power transformers. The relay can be configured with a maximum of four three-phase current inputs and four ground
current inputs, and can satisfy applications with transformer windings connected between two breakers, such as in a ring
bus or in breaker-and-a-half configurations. The T60 performs magnitude and phase shift compensation internally, eliminat-
ing requirements for external CT connections and auxiliary CTs.
The percent differential element is the main protection device in the T60. Instantaneous differential protection, volts-per- 2
hertz, restricted ground fault, and many current, voltage, and frequency-based protection elements are also incorporated.
The T60 includes sixteen fully programmable universal comparators, or FlexElements™, that provide additional flexibility
by allowing the user to customize their own protection functions that respond to any signals measured or calculated by the
relay.
The metering functions of the T60 include true RMS and phasors for currents and voltages, current harmonics and THD,
symmetrical components, frequency, power, power factor, and energy.
Diagnostic features include an event recorder capable of storing 1024 time-tagged events, oscillography capable of storing
up to 64 records with programmable trigger, content and sampling rate, and data logger acquisition of up to 16 channels,
with programmable content and sampling rate. The internal clock used for time-tagging can be synchronized with an IRIG-
B signal or via the SNTP protocol over the Ethernet port. This precise time stamping allows the sequence of events to be
determined throughout the system. Events can also be programmed (via FlexLogic™ equations) to trigger oscillography
data capture which may be set to record the measured parameters before and after the event for viewing on a personal
computer (PC). These tools significantly reduce troubleshooting time and simplify report generation in the event of a sys-
tem fault.
A faceplate RS232 port may be used to connect to a PC for the programming of settings and the monitoring of actual val-
ues. A variety of communications modules are available. Two rear RS485 ports allow independent access by operating and
engineering staff. All serial ports use the Modbus® RTU protocol. The RS485 ports may be connected to system computers
with baud rates up to 115.2 kbps. The RS232 port has a fixed baud rate of 19.2 kbps. Optional communications modules
include a 10/100Base-F Ethernet interface which can be used to provide fast, reliable communications in noisy environ-
ments. Another option provides two 10/100Base-F fiber optic ports for redundancy. The Ethernet port supports IEC 61850,
Modbus®/TCP, and TFTP protocols, and allows access to the relay via any standard web browser (T60 web pages). The
IEC 60870-5-104 protocol is supported on the Ethernet port. DNP 3.0 and IEC 60870-5-104 cannot be enabled at the same
time.
The T60 IEDs use flash memory technology which allows field upgrading as new features are added. The following Single
line diagram illustrates the relay functionality using ANSI (American National Standards Institute) device numbers.

MOUNTING CLEANING
Attach mounting brackets using 20 inch-pounds (±2 inch-pounds) Normally, cleaning is not required; but for situations where dust
of torque. has accumulated on the faceplate display, a dry cloth can be used.
Units that are stored in a de-energized state should be
powered up once per year, for one hour continuously, to
NOTE avoid deterioration of electrolytic capacitors.
a) HORIZONTAL UNITS
The T60 Transformer Protection System is available as a 19-inch rack horizontal mount unit with a removable faceplate.
The faceplate can be specified as either standard or enhanced at the time of ordering. The enhanced faceplate contains
additional user-programmable pushbuttons and LED indicators.
The modular design allows the relay to be easily upgraded or repaired by a qualified service person. The faceplate is
hinged to allow easy access to the removable modules, and is itself removable to allow mounting on doors with limited rear
depth. There is also a removable dust cover that fits over the faceplate, which must be removed when attempting to access
the keypad or RS232 communications port.
The case dimensions are shown below, along with panel cutout details for panel mounting. When planning the location of
your panel cutout, ensure that provision is made for the faceplate to swing open without interference to or from adjacent
equipment.
3
The relay must be mounted such that the faceplate sits semi-flush with the panel or switchgear door, allowing the operator
access to the keypad and the RS232 communications port. The relay is secured to the panel with the use of four screws
supplied with the relay.

additional user-programmable pushbuttons and LED indicators.
The modular design allows the relay to be easily upgraded or repaired by a qualified service person. The faceplate is
hinged to allow easy access to the removable modules, and is itself removable to allow mounting on doors with limited rear
depth. There is also a removable dust cover that fits over the faceplate, which must be removed when attempting to access
the keypad or RS232 communications port.
The case dimensions are shown below, along with panel cutout details for panel mounting. When planning the location of
your panel cutout, ensure that provision is made for the faceplate to swing open without interference to or from adjacent
equipment.
The relay must be mounted such that the faceplate sits semi-flush with the panel or switchgear door, allowing the operator
access to the keypad and the RS232 communications port. The relay is secured to the panel with the use of four screws
supplied with the relay.

WARNING
The relay, being modular in design, allows for the withdrawal and insertion of modules. Modules must only be replaced with
like modules in their original factory configured slots.
The enhanced faceplate can be opened to the left, once the thumb screw has been removed, as shown below. This allows
for easy accessibility of the modules for withdrawal. The new wide-angle hinge assembly in the enhanced front panel opens
completely and allows easy access to all modules in the T60.

The 4.0x release of the T60 relay includes new hardware modules.The new CPU modules are specified with codes
9E and higher. The new CT/VT modules are specified with the codes 8F and higher.
NOTE
The new CT/VT modules can only be used with new CPUs; similarly, old CT/VT modules can only be used with old
CPUs. To prevent hardware mismatches, the new modules have blue labels and a warning sticker stating “Attn.:
Ensure CPU and DSP module label colors are the same!”. In the event that there is a mismatch between the
CPU and CT/VT module, the relay will not function and a DSP ERROR or HARDWARE MISMATCH error will be dis-
played.
All other input and output modules are compatible with the new hardware. Firmware versions 4.0x and higher are
only compatible with the new hardware modules. Previous versions of the firmware (3.4x and earlier) are only com-
patible with the older hardware modules.

The relay follows a convention with respect to terminal number assignments which are three characters long assigned in
order by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from the
first slot position (nearest to CPU module) which is indicated by an arrow marker on the terminal block. See the following

Filter networks and transient protection clamps are used in the hardware to prevent damage caused by high peak voltage
transients, radio frequency interference (RFI), and electromagnetic interference (EMI). These protective components can
be damaged by application of the ANSI/IEEE C37.90 specified test voltage for a period longer than the specified one min-
ute.
CONTROL POWER SUPPLIED TO THE RELAY MUST BE CONNECTED TO THE MATCHING POWER SUPPLY

OCCUR!
The T60 relay, like almost all electronic relays, contains electrolytic capacitors. These capacitors are well
known to be subject to deterioration over time if voltage is not applied periodically. Deterioration can be
NOTE
avoided by powering the relays up once a year.
The power supply module can be ordered for two possible voltage ranges, with or without a redundant power option. Each
range has a dedicated input connection for proper operation. The ranges are as shown below (see the Technical specifica-
tions section of chapter 2 for additional details):
• Low (LO) range: 24 to 48 V (DC only) nominal.
• High (HI) range: 125 to 250 V nominal.
The power supply module provides power to the relay and supplies power for dry contact input connections.
The power supply module provides 48 V DC power for dry contact input connections and a critical failure relay (see the
Typical wiring diagram earlier). The critical failure relay is a form-C device that will be energized once control power is
applied and the relay has successfully booted up with no critical self-test failures. If on-going self-test diagnostic checks
detect a critical failure (see the Self-test errors section in chapter 7) or control power is lost, the relay will de-energize.
For high reliability systems, the T60 has a redundant option in which two T60 power supplies are placed in parallel on the
bus. If one of the power supplies become faulted, the second power supply will assume the full load of the relay without any
interruptions. Each power supply has a green LED on the front of the module to indicate it is functional. The critical fail relay
of the module will also indicate a faulted power supply.
An LED on the front of the control power module shows the status of the power supply:

A CT/VT module may have voltage inputs on channels 1 through 4 inclusive, or channels 5 through 8 inclusive. Channels 1
and 5 are intended for connection to phase A, and are labeled as such in the relay. Likewise, channels 2 and 6 are intended
for connection to phase B, and channels 3 and 7 are intended for connection to phase C.
Channels 4 and 8 are intended for connection to a single-phase source. For voltage inputs, these channel are labelled as
auxiliary voltage (VX). For current inputs, these channels are intended for connection to a CT between system neutral and
ground, and are labelled as ground current (IG).
Verify that the connection made to the relay nominal current of 1 A or 5 A matches the secondary rating of
the connected CTs. Unmatched CTs may result in equipment damage or inadequate protection.
CAUTION
CT/VT modules may be ordered with a standard ground current input that is the same as the phase current input. Each AC
current input has an isolating transformer and an automatic shorting mechanism that shorts the input when the module is
withdrawn from the chassis. There are no internal ground connections on the current inputs. Current transformers with 1 to
50000 A primaries and 1 A or 5 A secondaries may be used.
CT/VT modules with a sensitive ground input are also available. The ground CT input of the sensitive ground modules is
ten times more sensitive than the ground CT input of standard CT/VT modules. However, the phase CT inputs and phase
VT inputs are the same as those of regular CT/VT modules.
The above modules are available with enhanced diagnostics. These modules can automatically detect CT/VT hardware
failure and take the relay out of service.
CT connections for both ABC and ACB phase rotations are identical as shown in the Typical wiring diagram.
The exact placement of a zero-sequence core balance CT to detect ground fault current is shown below. Twisted-pair
cabling on the zero-sequence CT is recommended.

The T60 can be ordered with a process bus interface module. This module is designed to interface with the GE Multilin
HardFiber system, allowing bi-directional IEC 61850 fiber optic communications with up to eight HardFiber merging units,
known as Bricks. The HardFiber system has been designed to integrate seamlessly with the existing UR-series applica-
tions, including protection functions, FlexLogic™, metering, and communications.
The IEC 61850 process bus system offers the following benefits.
• Drastically reduces labor associated with design, installation, and testing of protection and control applications using
the T60 by reducing the number of individual copper terminations.
• Integrates seamlessly with existing T60 applications, since the IEC 61850 process bus interface module replaces the
traditional CT/VT modules.
Every contact input/output module has 24 terminal connections. They are arranged as three terminals per row, with eight
rows in total. A given row of three terminals may be used for the outputs of one relay. For example, for form-C relay outputs,
the terminals connect to the normally open (NO), normally closed (NC), and common contacts of the relay. For a form-A
output, there are options of using current or voltage detection for feature supervision, depending on the module ordered.
The terminal configuration for contact inputs is different for the two applications.
The contact inputs are grouped with a common return. The T60 has two versions of grouping: four inputs per common
return and two inputs per common return. When a contact input/output module is ordered, four inputs per common is used.
The four inputs per common allows for high-density inputs in combination with outputs, with a compromise of four inputs
sharing one common. If the inputs must be isolated per row, then two inputs per common return should be selected (4D
module).
The tables and diagrams on the following pages illustrate the module types (6A, etc.) and contact arrangements that may
be ordered for the relay. Since an entire row is used for a single contact output, the name is assigned using the module slot
position and row number. However, since there are two contact inputs per row, these names are assigned by module slot
position, row number, and column position.
Some form-A / solid-state relay outputs include circuits to monitor the DC voltage across the output contact when it is open,
and the DC current through the output contact when it is closed. Each of the monitors contains a level detector whose out-
put is set to logic “On = 1” when the current in the circuit is above the threshold setting. The voltage monitor is set to “On =
1” when the current is above about 1 to 2.5 mA, and the current monitor is set to “On = 1” when the current exceeds about
80 to 100 mA. The voltage monitor is intended to check the health of the overall trip circuit, and the current monitor can be
used to seal-in the output contact until an external contact has interrupted current flow.
Block diagrams are shown below for form-A and solid-state relay outputs with optional voltage monitor, optional current
monitor, and with no monitoring. The actual values shown for contact output 1 are the same for all contact outputs.

Figure 3–16: FORM-A AND SOLID-STATE CONTACT OUTPUTS WITH VOLTAGE AND CURRENT MONITORING
The operation of voltage and current monitors is reflected with the corresponding FlexLogic™ operands (CONT OP # VON,
CONT OP # VOFF, and CONT OP # ION) which can be used in protection, control, and alarm logic. The typical application of
the voltage monitor is breaker trip circuit integrity monitoring; a typical application of the current monitor is seal-in of the
control command.
Refer to the Digital elements section of chapter 5 for an example of how form-A and solid-state relay contacts can be
applied for breaker trip circuit integrity monitoring.
Relay contacts must be considered unsafe to touch when the unit is energized! If the relay contacts need to
be used for low voltage accessible applications, it is the customer’s responsibility to ensure proper insula-

tion levels!
USE OF FORM-A AND SOLID-STATE RELAY OUTPUTS IN HIGH IMPEDANCE CIRCUITS
NOTE For form-A and solid-state relay output contacts internally equipped with a voltage measuring cIrcuit across the
contact, the circuit has an impedance that can cause a problem when used in conjunction with external high input
impedance monitoring equipment such as modern relay test set trigger circuits. These monitoring circuits may con-
tinue to read the form-A contact as being closed after it has closed and subsequently opened, when measured as
an impedance.
The solution to this problem is to use the voltage measuring trigger input of the relay test set, and connect the form-
A contact through a voltage-dropping resistor to a DC voltage source. If the 48 V DC output of the power supply is
used as a source, a 500 , 10 W resistor is appropriate. In this configuration, the voltage across either the form-A
contact or the resistor can be used to monitor the state of the output.
Wherever a tilde “~” symbol appears, substitute with the slot position of the module; wherever a number
sign “#” appears, substitute the contact number
NOTE
When current monitoring is used to seal-in the form-A and solid-state relay contact outputs, the Flex-
Logic™ operand driving the contact output should be given a reset delay of 10 ms to prevent damage of
NOTE
the output contact (in situations when the element initiating the contact output is bouncing, at values in the
region of the pickup value).

CONTACT INPUTS:
A dry contact has one side connected to terminal B3b. This is the positive 48 V DC voltage rail supplied by the power sup-
ply module. The other side of the dry contact is connected to the required contact input terminal. Each contact input group
has its own common (negative) terminal which must be connected to the DC negative terminal (B3a) of the power supply
module. When a dry contact closes, a current of 1 to 3 mA will flow through the associated circuit.
A wet contact has one side connected to the positive terminal of an external DC power supply. The other side of this contact
is connected to the required contact input terminal. If a wet contact is used, then the negative side of the external source
must be connected to the relay common (negative) terminal of each contact group. The maximum external source voltage
for this arrangement is 300 V DC.
The voltage threshold at which each group of four contact inputs will detect a closed contact input is programmable as
17 V DC for 24 V sources, 33 V DC for 48 V sources, 84 V DC for 110 to 125 V sources, and 166 V DC for 250 V sources.

Contact outputs may be ordered as form-a or form-C. The form-A contacts may be connected for external circuit supervi-
sion. These contacts are provided with voltage and current monitoring circuits used to detect the loss of DC voltage in the
circuit, and the presence of DC current flowing through the contacts when the form-A contact closes. If enabled, the current
monitoring can be used as a seal-in signal to ensure that the form-A contact does not attempt to break the energized induc-
tive coil circuit and weld the output contacts.
There is no provision in the relay to detect a DC ground fault on 48 V DC control power external output. We
recommend using an external DC supply.

Transducer input modules can receive input signals from external dcmA output transducers (dcmA In) or resistance tem-
perature detectors (RTD). Hardware and software is provided to receive signals from these external transducers and con-
vert these signals into a digital format for use as required.
Transducer output modules provide DC current outputs in several standard dcmA ranges. Software is provided to configure
virtually any analog quantity used in the relay to drive the analog outputs.
Every transducer input/output module has a total of 24 terminal connections. These connections are arranged as three ter-
minals per row with a total of eight rows. A given row may be used for either inputs or outputs, with terminals in column "a"
having positive polarity and terminals in column "c" having negative polarity. Since an entire row is used for a single input/
output channel, the name of the channel is assigned using the module slot position and row number.
Each module also requires that a connection from an external ground bus be made to terminal 8b. The current outputs
3 require a twisted-pair shielded cable, where the shield is grounded at one end only. The figure below illustrates the trans-
ducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that may be ordered for the relay.
Wherever a tilde “~” symbol appears, substitute with the slot position of the module.
NOTE
A 9-pin RS232C serial port is located on the T60 faceplate for programming with a personal computer. All that is required to
use this interface is a personal computer running the EnerVista UR Setup software provided with the relay. Cabling for the
RS232 port is shown in the following figure for both 9-pin and 25-pin connectors.
The baud rate for this port is fixed at 19200 bps.
NOTE
a) OPTIONS
In addition to the faceplate RS232 port, the T60 provides two additional communication ports or a managed six-port Ether-
net switch, depending on the installed CPU module.
The CPU modules do not require a surge ground connection.

b) RS485 PORTS
RS485 data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternat-
ing over the same two wires. Through the use of these ports, continuous monitoring and control from a remote computer,
SCADA system or PLC is possible.
To minimize errors from noise, the use of shielded twisted pair wire is recommended. Correct polarity must also be
observed. For instance, the relays must be connected with all RS485 “+” terminals connected together, and all RS485 “–”
terminals connected together. Though data is transmitted over a two-wire twisted pair, all RS485 devices require a shared
reference, or common voltage. This common voltage is implied to be a power supply common. Some systems allow the
shield (drain wire) to be used as common wire and to connect directly to the T60 COM terminal (#3); others function cor-
rectly only if the common wire is connected to the T60 COM terminal, but insulated from the shield.
To avoid loop currents, the shield should be grounded at only one point. If other system considerations require the shield to
be grounded at more than one point, install resistors (typically 100 ohms) between the shield and ground at each grounding
point. Each relay should also be daisy-chained to the next one in the link. A maximum of 32 relays can be connected in this
manner without exceeding driver capability. For larger systems, additional serial channels must be added. It is also possible
to use commercially available repeaters to have more than 32 relays on a single channel. Star or stub connections should
be avoided entirely.
Lightning strikes and ground surge currents can cause large momentary voltage differences between remote ends of the
communication link. For this reason, surge protection devices are internally provided at both communication ports. An iso-
lated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum reliability, all
equipment should have similar transient protection devices installed.
Both ends of the RS485 circuit should also be terminated with an impedance as shown below.
CAUTION
The fiber optic communication ports allow for fast and efficient communications between relays at 10 Mbps or 100 Mbps.
Optical fiber may be connected to the relay supporting a wavelength of 820 nm in multi-mode or 1310 nm in multi-mode
and single-mode. The 10 Mbps rate is available for CPU modules 9G and 9H; 100Mbps is available for modules 9H, 9J, 9K,
9L, 9M, 9N, 9P, and 9R. The 9H, 9K, 9M, and 9R modules have a second pair of identical optical fiber transmitter and
receiver for redundancy.
The optical fiber sizes supported include 50/125 µm, 62.5/125 µm and 100/140 µm for 10 Mbps. The fiber optic port is
designed such that the response times will not vary for any core that is 100 µm or less in diameter, 62.5 µm for 100 Mbps.
For optical power budgeting, splices are required every 1 km for the transmitter/receiver pair. When splicing optical fibers,
the diameter and numerical aperture of each fiber must be the same. In order to engage or disengage the ST type connec-
tor, only a quarter turn of the coupling is required.
3.2.10 IRIG-B
IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices within
1 millisecond. The IRIG time code formats are serial, width-modulated codes which can be either DC level shifted or ampli-
tude modulated (AM). Third party equipment is available for generating the IRIG-B signal; this equipment may use a GPS
satellite system to obtain the time reference so that devices at different geographic locations can also be synchronized.

NOTE
The T60 direct inputs and outputs feature makes use of the type 7 series of communications modules. These modules are
also used by the L90 Line Differential Relay for inter-relay communications. The direct input and output feature uses the
communications channels provided by these modules to exchange digital state information between relays. This feature is
available on all UR-series relay models except for the L90 Line Differential relay.
The communications channels are normally connected in a ring configuration as shown below. The transmitter of one mod-
ule is connected to the receiver of the next module. The transmitter of this second module is then connected to the receiver
of the next module in the ring. This is continued to form a communications ring. The figure below illustrates a ring of four
UR-series relays with the following connections: UR1-Tx to UR2-Rx, UR2-Tx to UR3-Rx, UR3-Tx to UR4-Rx, and UR4-Tx
to UR1-Rx. A maximum of sixteen (16) UR-series relays can be connected in a single ring

The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged position as
the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the
clips simultaneously. When the clips have locked into position, the module will be fully inserted.
The switch settings for the internal and loop timing modes are shown below:
842752A1.CDR
3 In minimum remote loopback mode, the multiplexer is enabled to return the data from the external interface without any
processing to assist in diagnosing G.703 line-side problems irrespective of clock rate. Data enters from the G.703 inputs,
passes through the data stabilization latch which also restores the proper signal polarity, passes through the multiplexer
and then returns to the transmitter. The differential received data is processed and passed to the G.703 transmitter module
after which point the data is discarded. The G.703 receiver module is fully functional and continues to process data and
passes it to the differential Manchester transmitter module. Since timing is returned as it is received, the timing source is
expected to be from the G.703 line side of the interface.

a) DESCRIPTION
There are two RS422 inter-relay communications modules available: single-channel RS422 (module 7T) and dual-channel
RS422 (module 7W). The modules can be configured to run at 64 kbps or 128 kbps. AWG 24 twisted shielded pair cable is
recommended for external connections. These modules are protected by optically-isolated surge suppression devices.
The shield pins (6a and 7b) are internally connected to the ground pin (8a). Proper shield termination is as follows:
• Site 1: Terminate shield to pins 6a or 7b or both.
• Site 2: Terminate shield to COM pin 2b.
The clock terminating impedance should match the impedance of the line.

c) TRANSMIT TIMING
The RS422 interface accepts one clock input for transmit timing. It is important that the rising edge of the 64 kHz transmit
timing clock of the multiplexer interface is sampling the data in the center of the transmit data window. Therefore, it is impor-
tant to confirm clock and data transitions to ensure proper system operation. For example, the following figure shows the
positive edge of the Tx clock in the center of the Tx data bit.
Tx Clock
Tx Data
d) RECEIVE TIMING
The RS422 interface utilizes NRZI-MARK modulation code and; therefore, does not rely on an Rx clock to recapture data.
NRZI-MARK is an edge-type, invertible, self-clocking code.
To recover the Rx clock from the data-stream, an integrated DPLL (digital phase lock loop) circuit is utilized. The DPLL is
driven by an internal clock, which is 16-times over-sampled, and uses this clock along with the data-stream to generate a
data clock that can be used as the SCC (serial communication controller) receive clock.
The following figure shows the combined RS422 plus Fiber interface configuration at 64K baud. The 7L, 7M, 7N, 7P, and 74
modules are used in two-terminal with a redundant channel or three-terminal configurations where channel 1 is employed
via the RS422 interface (possibly with a multiplexer) and channel 2 via direct fiber.
AWG 24 twisted shielded pair is recommended for external RS422 connections and the shield should be grounded only at
one end. For the direct fiber channel, power budget issues should be addressed properly.
When using a LASER Interface, attenuators may be necessary to ensure that you do not exceed maximum

The UR-series IEEE C37.94 communication modules (modules types 2G, 2H, 76, and 77) are designed to interface with
IEEE C37.94 compliant digital multiplexers or an IEEE C37.94 compliant interface converter for use with direct input and
output applications for firmware revisions 3.30 and higher. The IEEE C37.94 standard defines a point-to-point optical link
for synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard
provides for speeds up to 64n kbps, where n = 1, 2,…, 12. The UR-series C37.94 communication modules are either
64 kbps (with n fixed at 1) for 128 kbps (with n fixed at 2). The frame is a valid International Telecommunications Union
(ITU-T) recommended G.704 pattern from the standpoint of framing and data rate. The frame is 256 bits and is repeated at
a frame rate of 8000 Hz, with a resultant bit rate of 2048 kbps.
The specifications for the module are as follows:.
• IEEE standard: C37.94 for 1 128 kbps optical fiber interface (for 2G and 2H modules) or C37.94 for 2 64 kbps opti-
3 •
cal fiber interface (for 76 and 77 modules).
Fiber optic cable type: 50 mm or 62.5 mm core diameter optical fiber.
• Fiber optic mode: multi-mode.
• Fiber optic cable length: up to 2 km.
• Fiber optic connector: type ST.
• Wavelength: 830 ±40 nm.
• Connection: as per all fiber optic connections, a Tx to Rx connection is required.
The UR-series C37.94 communication module can be connected directly to any compliant digital multiplexer that supports
the IEEE C37.94 standard as shown below.
The UR-series C37.94 communication module can be connected to the electrical interface (G.703, RS422, or X.21) of a
non-compliant digital multiplexer via an optical-to-electrical interface converter that supports the IEEE C37.94 standard, as
shown below.
The UR-series C37.94 communication module has six (6) switches that are used to set the clock configuration. The func-
tions of these control switches is shown below.
842753A1.CDR
For the internal timing mode, the system clock is generated internally. therefore, the timing switch selection should be inter-
nal timing for relay 1 and loop timed for relay 2. There must be only one timing source configured.
For the looped timing mode, the system clock is derived from the received line signal. Therefore, the timing selection
should be in loop timing mode for connections to higher order systems.
The IEEE C37.94 communications module cover removal procedure is as follows:
1. Remove the IEEE C37.94 module (type 2G, 2H, 76 or 77 module):
The ejector/inserter clips located at the top and at the bottom of each module, must be pulled simultaneously in order
to release the module for removal. Before performing this action, control power must be removed from the relay.
The original location of the module should be recorded to help ensure that the same or replacement module is inserted
into the correct slot.
2. Remove the module cover screw.
3. Remove the top cover by sliding it towards the rear and then lift it upwards. 3
4. Set the timing selection switches (channel 1, channel 2) to the desired timing modes (see description above).
5. Replace the top cover and the cover screw.
6. Re-insert the IEEE C37.94 module. Take care to ensure that the correct module type is inserted into the correct slot
position. The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged posi-
tion as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis,
engage the clips simultaneously. When the clips have locked into position, the module will be fully inserted.
The UR-series C37.94SM communication modules (2A and 2B) are designed to interface with modified IEEE C37.94 com-
pliant digital multiplexers or IEEE C37.94 compliant interface converters that have been converted from 820 nm multi-mode
fiber optics to 1300 nm ELED single-mode fiber optics. The IEEE C37.94 standard defines a point-to-point optical link for
synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard pro-
vides for speeds up to 64n kbps, where n = 1, 2,…, 12. The UR-series C37.94SM communication module is 64 kbps only
with n fixed at 1. The frame is a valid International Telecommunications Union (ITU-T) recommended G.704 pattern from
the standpoint of framing and data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit
rate of 2048 kbps.
The specifications for the module are as follows:
• Emulated IEEE standard: emulates C37.94 for 1 64 kbps optical fiber interface (modules set to n = 1 or 64 kbps).
3 • Fiber optic cable type: 9/125 m core diameter optical fiber.
• Fiber optic mode: single-mode, ELED compatible with HP HFBR-1315T transmitter and HP HFBR-2316T receiver.
• Fiber optic cable length: up to 10 km.
• Fiber optic connector: type ST.
• Wavelength: 1300 ±40 nm.
• Connection: as per all fiber optic connections, a Tx to Rx connection is required.
The UR-series C37.94SM communication module can be connected directly to any compliant digital multiplexer that sup-
ports C37.94SM as shown below.
It can also can be connected directly to any other UR-series relay with a C37.94SM module as shown below.
The UR-series C37.94SM communication module has six (6) switches that are used to set the clock configuration. The
functions of these control switches is shown below.

The type 2S and 2T embedded managed switch modules are supported by UR-series relays containing type 9S CPU mod-
ules with revisions 5.5x and higher. The modules communicate to the T60 through an internal Ethernet port (referred to as
the UR port or port 7) and provide an additional six external Ethernet ports: two 10/100Base-T ports and four multimode ST
100Base-FX ports.
The Ethernet switch module should be powered up before or at the same time as the T60. Otherwise, the switch
module will not be detected on power up and the EQUIPMENT MISMATCH: ORDERCODE XXX self-test warning will be
NOTE issued.
3 The type 2S and 2T managed Ethernet switch modules provide two 10/100Base-T and four multimode ST 100Base-FX
external Ethernet ports accessible through the rear of the module. In addition, a serial console port is accessible from the
front of the module (requires the front panel faceplate to be open).

a) DESCRIPTION
This section describes the process for upgrading firmware on a UR-2S or UR-2T switch module.
There are several ways of updating firmware on a switch module:
• Using the EnerVista UR Setup software.
• Serially using the T60 switch module console port.
• Using FTP or TFTP through the T60 switch module console port.
It is highly recommended to use the EnerVista UR Setup software to upgrade firmware on a T60 switch module.
Firmware upgrades using the serial port, TFTP, and FTP are described in detail in the switch module manual.

2. Using the EnerVista UR Setup program, select the Settings > Product Setup > Communications > Ethernet Switch
> Firmware Upload menu item.
The following popup screen will appear warning that the settings will be lost when the firmware is upgraded.
It is highly recommended that you save the switch settings before upgrading the firmware.
NOTE
3. After saving the settings file, proceed with the firmware upload by selecting Yes to the above warning.
Another window will open, asking you to point to the location of the firmware file to be uploaded. 3
4. Select the firmware file to be loaded on to the Switch, and select the Open option.
The following window will pop up, indicating that the firmware file transfer is in progress.
If the firmware load was successful, the following window will appear:
Note
The switch will automatically reboot after a successful firmware file transfer.
NOTE
5. Once the firmware has been successfully uploaded to the switch module, load the settings file using the procedure
described earlier.
The following table provides details about Ethernet module self-test errors.
Be sure to enable the ETHERNET SWITCH FAIL setting in the PRODUCT SETUP USER-PROGRAMMABLE SELF-TESTS menu
and the relevant PORT 1 EVENTS through PORT 6 EVENTS settings under the PRODUCT SETUP COMMUNICATIONS
ETHERNET SWITCH menu.
The EnerVista UR Setup software provides a graphical user interface (GUI) as one of two human interfaces to a UR device.
The alternate human interface is implemented via the device’s faceplate keypad and display (refer to the Faceplate inter-
face section in this chapter).
The EnerVista UR Setup software provides a single facility to configure, monitor, maintain, and trouble-shoot the operation
of relay functions, connected over local or wide area communication networks. It can be used while disconnected (off-line)
or connected (on-line) to a UR device. In off-line mode, settings files can be created for eventual downloading to the device.
In on-line mode, you can communicate with the device in real-time.
The EnerVista UR Setup software, provided with every T60 relay, can be run from any computer supporting Microsoft Win-
dows® 95, 98, NT, 2000, ME, and XP. This chapter provides a summary of the basic EnerVista UR Setup software interface
features. The EnerVista UR Setup Help File provides details for getting started and using the EnerVista UR Setup software
interface.
To start using the EnerVista UR Setup software, a site definition and device definition must first be created. See the EnerV-
ista UR Setup Help File or refer to the Connecting EnerVista UR Setup with the T60 section in Chapter 1 for details.
f) FILE SUPPORT
• Execution: Any EnerVista UR Setup file which is double clicked or opened will launch the application, or provide focus
to the already opened application. If the file was a settings file (has a URS extension) which had been removed from
the Settings List tree menu, it will be added back to the Settings List tree menu.
• Drag and Drop: The Site List and Settings List control bar windows are each mutually a drag source and a drop target
for device-order-code-compatible files or individual menu items. Also, the Settings List control bar window and any
Windows Explorer directory folder are each mutually a file drag source and drop target.
New files which are dropped into the Settings List window are added to the tree which is automatically sorted alphabet-
ically with respect to settings file names. Files or individual menu items which are dropped in the selected device menu
in the Site List window will automatically be sent to the on-line communicating device.
g) FIRMWARE UPGRADES
The firmware of a T60 device can be upgraded, locally or remotely, via the EnerVista UR Setup software. The correspond-
ing instructions are provided by the EnerVista UR Setup Help file under the topic “Upgrading Firmware”.
Modbus addresses assigned to firmware modules, features, settings, and corresponding data items (i.e. default
values, minimum/maximum values, data type, and item size) may change slightly from version to version of firm-
NOTE
ware. The addresses are rearranged when new features are added or existing features are enhanced or modified.
The EEPROM DATA ERROR message displayed after upgrading/downgrading the firmware is a resettable, self-test
message intended to inform users that the Modbus addresses have changed with the upgraded firmware. This
message does not signal any problems when appearing after firmware upgrades.
The EnerVista UR Setup software main window supports the following primary display components:
1. Title bar which shows the pathname of the active data view.
2. Main window menu bar.
3. Main window tool bar.
4. Site list control bar window.
5. Settings list control bar window.
6. Device data view windows, with common tool bar.
7. Settings file data view windows, with common tool bar. 4
8. Workspace area with data view tabs.
9. Status bar.
10. Quick action hot links.

Setting file templates simplify the configuration and commissioning of multiple relays that protect similar assets. An exam-
ple of this is a substation that has ten similar feeders protected by ten UR-series F60 relays.
In these situations, typically 90% or greater of the settings are identical between all devices. The templates feature allows
engineers to configure and test these common settings, then lock them so they are not available to users. For example,
these locked down settings can be hidden from view for field engineers, allowing them to quickly identify and concentrate
on the specific settings.
The remaining settings (typically 10% or less) can be specified as editable and be made available to field engineers install-
ing the devices. These will be settings such as protection element pickup values and CT and VT ratios.
The settings template mode allows the user to define which settings will be visible in EnerVista UR Setup. Settings tem-
plates can be applied to both settings files (settings file templates) and online devices (online settings templates). The func-
tionality is identical for both purposes.
The settings template feature requires that both the EnerVista UR Setup software and the T60 firmware are at ver-
sions 5.40 or higher.
NOTE
The software will prompt for a template password. This password is required to use the template feature and must be
at least four characters in length.
3. Enter and re-enter the new password, then click OK to continue.
The online settings template is now enabled. The device is now in template editing mode.
By default, all settings are specified as locked and displayed against a grey background. The icon on the upper right of
the settings window will also indicate that EnerVista UR Setup is in EDIT mode. The following example shows the
phase time overcurrent settings window in edit mode.
The software will prompt for a template password. This password must be at least four characters in length.
Figure 4–4: APPLYING TEMPLATES VIA THE VIEW IN TEMPLATE MODE COMMAND
Viewing the settings in template mode also modifies the settings tree, showing only the settings categories that contain
editable settings. The effect of applying the template to a typical settings tree view is shown below.

4. Verify one more time that you wish to remove the template by clicking Yes.
The EnerVista software will remove all template information and all settings will be available.
The UR allows users to secure parts or all of a FlexLogic™ equation, preventing unauthorized viewing or modification of
critical FlexLogic™ applications. This is accomplished using the settings template feature to lock individual entries within
FlexLogic™ equations.
Secured FlexLogic™ equations will remain secure when files are sent to and retrieved from any UR-series device.
4 The following procedure describes how to lock individual entries of a FlexLogic™ equation.
1. Right-click the settings file or online device and select the Template Mode > Create Template item to enable the set-
tings template feature.
2. Select the FlexLogic > FlexLogic Equation Editor settings menu item.
By default, all FlexLogic™ entries are specified as viewable and displayed against a yellow background. The icon on
the upper right of the window will also indicate that EnerVista UR Setup is in EDIT mode.
3. Specify which entries to lock by clicking on them.
The locked entries will be displayed against a grey background as shown in the example below.
Once the template has been applied, users will only be able to view and edit the FlexLogic™ entries not locked by the tem-
plate. The effect of applying the template to the FlexLogic™ entries in the above procedure is shown below.
Typical FlexLogic™ entries without template applied. Typical FlexLogic™ entries locked with template via
the Template Mode > View In Template Mode command.
842861A1.CDR
4 3. Enter the serial number of the T60 device to lock to the settings file in the Serial # Lock field.
The settings file and corresponding secure FlexLogic™ equations are now locked to the T60 device specified by the serial
number.
A traceability feature for settings files allows the user to quickly determine if the settings in a T60 device have been
changed since the time of installation from a settings file. When a settings file is transfered to a T60 device, the date, time,
and serial number of the T60 are sent back to EnerVista UR Setup and added to the settings file on the local PC. This infor-
mation can be compared with the T60 actual values at any later date to determine if security has been compromised.
The traceability information is only included in the settings file if a complete settings file is either transferred to the T60
device or obtained from the T60 device. Any partial settings transfers by way of drag and drop do not add the traceability
information to the settings file.
The serial number of the UR-series device and the file transfer
date are added to the settings file when settings files
are transferred to the device.
1. The transfer date of a setting file written to a T60 is logged in the relay and can be viewed via EnerVista UR Setup or
the front panel display. Likewise, the transfer date of a setting file saved to a local PC is logged in EnerVista UR Setup.
2. Comparing the dates stored in the relay and on the settings file at any time in the future will indicate if any changes
have been made to the relay configuration since the settings file was saved.

• TROUBLE: This LED indicates that the relay has detected an internal problem.
• TEST MODE: This LED indicates that the relay is in test mode.
• TRIP: This LED indicates that the FlexLogic™ operand serving as a trip switch has operated. This indicator always
latches; as such, a reset command must be initiated to allow the latch to be reset.
• ALARM: This LED indicates that the FlexLogic™ operand serving as an alarm switch has operated. This indicator is
never latched.
• PICKUP: This LED indicates that an element is picked up. This indicator is never latched.
The event cause indicators in the first column are described below.
Events cause LEDs are turned on or off by protection elements that have their respective target setting selected as either
“Enabled” or “Latched”. If a protection element target setting is “Enabled”, then the corresponding event cause LEDs
remain on as long as operate operand associated with the element remains asserted. If a protection element target setting
is “Latched”, then the corresponding event cause LEDs turn on when the operate operand associated with the element is
asserted and remain on until the RESET button on the front panel is pressed after the operand is reset.
All elements that are able to discriminate faulted phases can independently turn off or on the phase A, B or C LEDs. This
includes phase instantaneous overcurrent, phase undervoltage, etc. This means that the phase A, B, and C operate oper-
ands for individual protection elements are ORed to turn on or off the phase A, B or C LEDs.
• VOLTAGE: This LED indicates voltage was involved. 4
• CURRENT: This LED indicates current was involved.
• FREQUENCY: This LED indicates frequency was involved.
• OTHER: This LED indicates a composite function was involved.
• PHASE A: This LED indicates phase A was involved.
• PHASE B: This LED indicates phase B was involved.
• PHASE C: This LED indicates phase C was involved.
• NEUTRAL/GROUND: This LED indicates that neutral or ground was involved.
The user-programmable LEDs consist of 48 amber LED indicators in four columns. The operation of these LEDs is user-
defined. Support for applying a customized label beside every LED is provided. Default labels are shipped in the label pack-
age of every T60, together with custom templates. The default labels can be replaced by user-printed labels.
User customization of LED operation is of maximum benefit in installations where languages other than English are used to
communicate with operators. Refer to the User-programmable LEDs section in chapter 5 for the settings used to program
the operation of the LEDs on these panels.
b) STANDARD FACEPLATE
The standard faceplate consists of three panels with LED indicators, keys, and a communications port. The RESET key is

Two methods of editing and storing a numerical setting value are available.
• 0 to 9 and decimal point: The relay numeric keypad works the same as that of any electronic calculator. A number is
entered one digit at a time. The leftmost digit is entered first and the rightmost digit is entered last. Pressing the MES-
SAGE LEFT key or pressing the ESCAPE key, returns the original value to the display.
• VALUE keys: The VALUE UP key increments the displayed value by the step value, up to the maximum value allowed.
4 While at the maximum value, pressing the VALUE UP key again will allow the setting selection to continue upward
from the minimum value. The VALUE DOWN key decrements the displayed value by the step value, down to the mini-
mum value. While at the minimum value, pressing the VALUE DOWN key again will allow the setting selection to con-
tinue downward from the maximum value.
FLASH MESSAGE As an example, set the flash message time setting to 2.5 seconds. Press the appropriate
TIME: 2.5 s numeric keys in the sequence “2 . 5". The display message will change as the digits are
being entered.

ELEMENTS
In the design of UR relays, the term element is used to describe a feature that is based around a comparator. The compar-
ator is provided with an input (or set of inputs) that is tested against a programmed setting (or group of settings) to deter-
mine if the input is within the defined range that will set the output to logic 1, also referred to as setting the flag. A single
comparator may make multiple tests and provide multiple outputs; for example, the time overcurrent comparator sets a
pickup flag when the current input is above the setting and sets an operate flag when the input current has been at a level
above the pickup setting for the time specified by the time-current curve settings. All comparators use analog parameter
actual values as the input.
The exception to the above rule are the digital elements, which use logic states as inputs.
5 NOTE
Elements are arranged into two classes, grouped and control. Each element classed as a grouped element is provided with
six alternate sets of settings, in setting groups numbered 1 through 6. The performance of a grouped element is defined by
the setting group that is active at a given time. The performance of a control element is independent of the selected active
setting group.
The main characteristics of an element are shown on the element logic diagram. This includes the inputs, settings, fixed
logic, and the output operands generated (abbreviations used on scheme logic diagrams are defined in Appendix F).
Some settings for current and voltage elements are specified in per-unit (pu) calculated quantities:
pu quantity = (actual quantity) / (base quantity)
For current elements, the base quantity is the nominal secondary or primary current of the CT.
Where the current source is the sum of two CTs with different ratios, the base quantity will be the common secondary or pri-
mary current to which the sum is scaled (that is, normalized to the larger of the two rated CT inputs). For example, if CT1 =
300 / 5 A and CT2 = 100 / 5 A, then in order to sum these, CT2 is scaled to the CT1 ratio. In this case, the base quantity will
be 5 A secondary or 300 A primary.
For voltage elements the base quantity is the nominal primary voltage of the protected system which corresponds (based
on VT ratio and connection) to secondary VT voltage applied to the relay.
For example, on a system with a 13.8 kV nominal primary voltage and with 14400:120 V delta-connected VTs, the second-
ary nominal voltage (1 pu) would be:
13800
---------------- 120 = 115 V (EQ 5.1)
14400
For wye-connected VTs, the secondary nominal voltage (1 pu) would be:
13800
---------------- 120
---------- = 66.4 V (EQ 5.2)
14400 3
Many settings are common to most elements and are discussed below:
• FUNCTION setting: This setting programs the element to be operational when selected as “Enabled”. The factory
default is “Disabled”. Once programmed to “Enabled”, any element associated with the function becomes active and all
options become available.
• NAME setting: This setting is used to uniquely identify the element.
• SOURCE setting: This setting is used to select the parameter or set of parameters to be monitored.
• PICKUP setting: For simple elements, this setting is used to program the level of the measured parameter above or
below which the pickup state is established. In more complex elements, a set of settings may be provided to define the
range of the measured parameters which will cause the element to pickup.
• PICKUP DELAY setting: This setting sets a time-delay-on-pickup, or on-delay, for the duration between the pickup
and operate output states.
• RESET DELAY setting: This setting is used to set a time-delay-on-dropout, or off-delay, for the duration between the
Operate output state and the return to logic 0 after the input transits outside the defined pickup range.
• BLOCK setting: The default output operand state of all comparators is a logic 0 or “flag not set”. The comparator
remains in this default state until a logic 1 is asserted at the RUN input, allowing the test to be performed. If the RUN
input changes to logic 0 at any time, the comparator returns to the default state. The RUN input is used to supervise
the comparator. The BLOCK input is used as one of the inputs to RUN control.
• TARGET setting: This setting is used to define the operation of an element target message. When set to “Disabled”,
no target message or illumination of a faceplate LED indicator is issued upon operation of the element. When set to
“Self-Reset”, the target message and LED indication follow the operate state of the element, and self-resets once the
operate element condition clears. When set to “Latched”, the target message and LED indication will remain visible
after the element output returns to logic 0 until a RESET command is received by the relay.
• EVENTS setting: This setting is used to control whether the pickup, dropout or operate states are recorded by the
event recorder. When set to “Disabled”, element pickup, dropout or operate are not recorded as events. When set to
“Enabled”, events are created for:
5
(Element) PKP (pickup)
(Element) DPO (dropout)
(Element) OP (operate)
The DPO event is created when the measure and decide comparator output transits from the pickup state (logic 1) to
the dropout state (logic 0). This could happen when the element is in the operate state if the reset delay time is not 0.
a) BACKGROUND
The T60 may be used on systems with breaker-and-a-half or ring bus configurations. In these applications, each of the two
three-phase sets of individual phase currents (one associated with each breaker) can be used as an input to a breaker fail-
ure element. The sum of both breaker phase currents and 3I_0 residual currents may be required for the circuit relaying
and metering functions. For a three-winding transformer application, it may be required to calculate watts and vars for each
of three windings, using voltage from different sets of VTs. These requirements can be satisfied with a single UR, equipped
with sufficient CT and VT input channels, by selecting the parameter to measure. A mechanism is provided to specify the
AC parameter (or group of parameters) used as the input to protection/control comparators and some metering elements.
Selection of the parameter(s) to measure is partially performed by the design of a measuring element or protection/control
comparator by identifying the type of parameter (fundamental frequency phasor, harmonic phasor, symmetrical component,
total waveform RMS magnitude, phase-phase or phase-ground voltage, etc.) to measure. The user completes the process
by selecting the instrument transformer input channels to use and some of the parameters calculated from these channels.
The input parameters available include the summation of currents from multiple input channels. For the summed currents of
phase, 3I_0, and ground current, current from CTs with different ratios are adjusted to a single ratio before summation.
A mechanism called a source configures the routing of CT and VT input channels to measurement sub-systems. Sources,
in the context of UR series relays, refer to the logical grouping of current and voltage signals such that one source contains
all the signals required to measure the load or fault in a particular power apparatus. A given source may contain all or some
of the following signals: three-phase currents, single-phase ground current, three-phase voltages and an auxiliary voltage
from a single VT for checking for synchronism.
To illustrate the concept of sources, as applied to current inputs only, consider the breaker-and-a-half scheme below. In this
application, the current flows as shown by the arrows. Some current flows through the upper bus bar to some other location
or power equipment, and some current flows into transformer winding 1. The current into winding 1 is the phasor sum (or
difference) of the currents in CT1 and CT2 (whether the sum or difference is used depends on the relative polarity of the CT
connections). The same considerations apply to transformer winding 2. The protection elements require access to the net
current for transformer protection, but some elements may need access to the individual currents from CT1 and CT2.

Banks are ordered sequentially from the block of lower-numbered channels to the block of higher-numbered channels, and
from the CT/VT module with the lowest slot position letter to the module with the highest slot position letter, as follows:
INCREASING SLOT POSITION LETTER -->
CT/VT MODULE 1 CT/VT MODULE 2 CT/VT MODULE 3
< bank 1 > < bank 3 > < bank 5 >
< bank 2 > < bank 4 > < bank 6 >
The UR platform allows for a maximum of three sets of three-phase voltages and six sets of three-phase currents. The
result of these restrictions leads to the maximum number of CT/VT modules in a chassis to three. The maximum number of
sources is six. A summary of CT/VT module configurations is shown below.

SECURITY ACCESS
PASSWORD ACCESS Range: Disabled, Enabled
MESSAGE
EVENTS: Disabled
Two levels of password security are provided via the ACCESS LEVEL setting: command and setting. The factory service level
is not available and intended for factory use only.
The following operations are under command password supervision:
• Changing the state of virtual inputs.
• Clearing the event records.
5 •
•
Clearing the oscillography records.
Changing the date and time.
• Clearing energy records.
• Clearing the data logger.
• Clearing the user-programmable pushbutton states.
The following operations are under setting password supervision:
• Changing any setting.
• Test mode operation.
The command and setting passwords are defaulted to “0” when the relay is shipped from the factory. When a password is
set to “0”, the password security feature is disabled.
The T60 supports password entry from a local or remote connection.
Local access is defined as any access to settings or commands via the faceplate interface. This includes both keypad entry
and the through the faceplate RS232 port. Remote access is defined as any access to settings or commands via any rear
communications port. This includes both Ethernet and RS485 connections. Any changes to the local or remote passwords
enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the correspond-
ing connection password. If the connection is to the back of the T60, the remote password must be used. If the connection
is to the RS232 port of the faceplate, the local password must be used.
The PASSWORD ACCESS EVENTS settings allows recording of password access events in the event recorder.
The local setting and command sessions are initiated by the user through the front panel display and are disabled either by
the user or by timeout (via the setting and command level access timeout settings). The remote setting and command ses-
sions are initiated by the user through the EnerVista UR Setup software and are disabled either by the user or by timeout.
The state of the session (local or remote, setting or command) determines the state of the following FlexLogic™ operands.
• ACCESS LOC SETG OFF: Asserted when local setting access is disabled.
• ACCESS LOC SETG ON: Asserted when local setting access is enabled.
• ACCESS LOC CMND OFF: Asserted when local command access is disabled.
• ACCESS LOC CMND ON: Asserted when local command access is enabled.
• ACCESS REM SETG OFF: Asserted when remote setting access is disabled.
• ACCESS REM SETG ON: Asserted when remote setting access is enabled.
• ACCESS REM CMND OFF: Asserted when remote command access is disabled.
• ACCESS REM CMND ON: Asserted when remote command access is enabled.
The appropriate events are also logged in the Event Recorder as well. The FlexLogic™ operands and events are updated
every five seconds.
A command or setting write operation is required to update the state of all the remote and local security operands
shown above.
NOTE
b) LOCAL PASSWORDS
PATH: SETTINGS PRODUCT SETUP SECURITY CHANGE LOCAL PASSWORDS
Proper password codes are required to enable each access level. A password consists of 1 to 10 numerical characters.
5
When a CHANGE COMMAND PASSWORD or CHANGE SETTING PASSWORD setting is programmed to “Yes” via the front panel
interface, the following message sequence is invoked:
1. ENTER NEW PASSWORD: ____________.
2. VERIFY NEW PASSWORD: ____________.
3. NEW PASSWORD HAS BEEN STORED.
To gain write access to a “Restricted” setting, program the ACCESS LEVEL setting in the main security menu to “Setting” and
then change the setting, or attempt to change the setting and follow the prompt to enter the programmed password. If the
password is correctly entered, access will be allowed. Accessibility automatically reverts to the “Restricted” level according
to the access level timeout setting values.
If an entered password is lost (or forgotten), consult the factory with the corresponding ENCRYPTED PASSWORD.
If the setting and command passwords are identical, then this one password allows access to both com-
mands and settings.
NOTE
c) REMOTE PASSWORDS
The remote password settings are only visible from a remote connection via the EnerVista UR Setup software. Select the
Settings > Product Setup > Password Security menu item to open the remote password settings window.
Proper passwords are required to enable each command or setting level access. A command or setting password consists
of 1 to 10 numerical characters and are initially programmed to “0”. The following procedure describes how the set the com-
mand or setting password.
1. Enter the new password in the Enter New Password field.
2. Re-enter the password in the Confirm New Password field.
3. Click the Change button. This button will not be active until the new password matches the confirmation password.
4. If the original password is not “0”, then enter the original password in the Enter Password field and click the Send
Password to Device button.
5. The new password is accepted and a value is assigned to the ENCRYPTED PASSWORD item.
If a command or setting password is lost (or forgotten), consult the factory with the corresponding Encrypted Password
value.
d) ACCESS SUPERVISION
PATH: SETTINGS PRODUCT SETUP SECURITY ACCESS SUPERVISION
The UNAUTHORIZED ACCESS operand is reset with the COMMANDS CLEAR RECORDS RESET UNAUTHORIZED
ALARMS command. Therefore, to apply this feature with security, the command level should be password-protected. The
operand does not generate events or targets.
If events or targets are required, the UNAUTHORIZED ACCESS operand can be assigned to a digital element programmed
with event logs or targets enabled.
The access level timeout settings are shown below.
PATH: SETTINGS PRODUCT SETUP SECURITY ACCESS SUPERVISION ACCESS LEVEL TIMEOUTS
These settings allow the user to specify the length of inactivity required before returning to the restricted access level. Note
that the access level will set as restricted if control power is cycled.
• COMMAND LEVEL ACCESS TIMEOUT: This setting specifies the length of inactivity (no local or remote access)
required to return to restricted access from the command password level.
• SETTING LEVEL ACCESS TIMEOUT: This setting specifies the length of inactivity (no local or remote access)
required to return to restricted access from the command password level.

The dual permission security access feature provides a mechanism for customers to prevent unauthorized or unintended
upload of settings to a relay through the local or remote interfaces interface.
The following settings are available through the local (front panel) interface only.
• LOCAL SETTING AUTH: This setting is used for local (front panel or RS232 interface) setting access supervision.
Valid values for the FlexLogic™ operands are either “On” (default) or any physical “Contact Input ~~ On” value.
If this setting is “On“, then local setting access functions as normal; that is, a local setting password is required. If this
setting is any contact input on FlexLogic™ operand, then the operand must be asserted (set as on) prior to providing
the local setting password to gain setting access.
If setting access is not authorized for local operation (front panel or RS232 interface) and the user attempts to obtain
setting access, then the UNAUTHORIZED ACCESS message is displayed on the front panel.
• REMOTE SETTING AUTH: This setting is used for remote (Ethernet or RS485 interfaces) setting access supervision.
If this setting is “On” (the default setting), then remote setting access functions as normal; that is, a remote password is
required). If this setting is “Off”, then remote setting access is blocked even if the correct remote setting password is
provided. If this setting is any other FlexLogic™ operand, then the operand must be asserted (set as on) prior to pro-
viding the remote setting password to gain setting access.
• ACCESS AUTH TIMEOUT: This setting represents the timeout delay for local setting access. This setting is applicable
when the LOCAL SETTING AUTH setting is programmed to any operand except “On”. The state of the FlexLogic™ oper-
and is continuously monitored for an off-to-on transition. When this occurs, local access is permitted and the timer pro-
grammed with the ACCESS AUTH TIMEOUT setting value is started. When this timer expires, local setting access is
immediately denied. If access is permitted and an off-to-on transition of the FlexLogic™ operand is detected, the time-
out is restarted. The status of this timer is updated every 5 seconds.
The following settings are available through the remote (EnerVista UR Setup) interface only. Select the Settings > Product
Setup > Security menu item to display the security settings window.
The Remote Settings Authorization setting is used for remote (Ethernet or RS485 interfaces) setting access supervision.
If this setting is “On” (the default setting), then remote setting access functions as normal; that is, a remote password is
required). If this setting is “Off”, then remote setting access is blocked even if the correct remote setting password is pro-
vided. If this setting is any other FlexLogic™ operand, then the operand must be asserted (set as on) prior to providing the
remote setting password to gain setting access.
The Access Authorization Timeout setting represents the timeout delay remote setting access. This setting is applicable
when the Remote Settings Authorization setting is programmed to any operand except “On” or “Off”. The state of the
FlexLogic™ operand is continuously monitored for an off-to-on transition. When this occurs, remote setting access is per-
mitted and the timer programmed with the Access Authorization Timeout setting value is started. When this timer
expires, remote setting access is immediately denied. If access is permitted and an off-to-on transition of the FlexLogic™
operand is detected, the timeout is restarted. The status of this timer is updated every 5 seconds.
Some relay messaging characteristics can be modified to suit different situations using the display properties settings.
• LANGUAGE: This setting selects the language used to display settings, actual values, and targets. The range is
dependent on the order code of the relay.
• FLASH MESSAGE TIME: Flash messages are status, warning, error, or information messages displayed for several
seconds in response to certain key presses during setting programming. These messages override any normal mes-
sages. The duration of a flash message on the display can be changed to accommodate different reading rates.
• DEFAULT MESSAGE TIMEOUT: If the keypad is inactive for a period of time, the relay automatically reverts to a
default message. The inactivity time is modified via this setting to ensure messages remain on the screen long enough
during programming or reading of actual values.
• DEFAULT MESSAGE INTENSITY: To extend phosphor life in the vacuum fluorescent display, the brightness can be
attenuated during default message display. During keypad interrogation, the display always operates at full brightness.
• SCREEN SAVER FEATURE and SCREEN SAVER WAIT TIME: These settings are only visible if the T60 has a liquid
crystal display (LCD) and control its backlighting. When the SCREEN SAVER FEATURE is “Enabled”, the LCD backlighting
is turned off after the DEFAULT MESSAGE TIMEOUT followed by the SCREEN SAVER WAIT TIME, providing that no keys
have been pressed and no target messages are active. When a keypress occurs or a target becomes active, the LCD
backlighting is turned on.
• CURRENT CUT-OFF LEVEL: This setting modifies the current cut-off threshold. Very low currents (1 to 2% of the
rated value) are very susceptible to noise. Some customers prefer very low currents to display as zero, while others
prefer the current be displayed even when the value reflects noise rather than the actual signal. The T60 applies a cut-
off value to the magnitudes and angles of the measured currents. If the magnitude is below the cut-off level, it is substi-
tuted with zero. This applies to phase and ground current phasors as well as true RMS values and symmetrical compo-
nents. The cut-off operation applies to quantities used for metering, protection, and control, as well as those used by
communications protocols. Note that the cut-off level for the sensitive ground input is 10 times lower that the CURRENT
CUT-OFF LEVEL setting value. Raw current samples available via oscillography are not subject to cut-off.
• VOLTAGE CUT-OFF LEVEL: This setting modifies the voltage cut-off threshold. Very low secondary voltage measure-
ments (at the fractional volt level) can be affected by noise. Some customers prefer these low voltages to be displayed
as zero, while others prefer the voltage to be displayed even when the value reflects noise rather than the actual sig-
nal. The T60 applies a cut-off value to the magnitudes and angles of the measured voltages. If the magnitude is below
the cut-off level, it is substituted with zero. This operation applies to phase and auxiliary voltages, and symmetrical
components. The cut-off operation applies to quantities used for metering, protection, and control, as well as those
used by communications protocols. Raw samples of the voltages available via oscillography are not subject cut-off.
The CURRENT CUT-OFF LEVEL and the VOLTAGE CUT-OFF LEVEL are used to determine the metered power cut-off levels. The
power cut-off level is calculated as shown below. For Delta connections:
We have:
CT primary = “100 A”, and
VT primary = PHASE VT SECONDARY x PHASE VT RATIO = 66.4 V x 208 = 13811.2 V
The power cut-off is therefore:
power cut-off = (CURRENT CUT-OFF LEVEL VOLTAGE CUT-OFF LEVEL CT primary VT primary)/VT secondary
= ( 3 0.02 pu 1.0 V 100 A 13811.2 V) / 66.4 V
= 720.5 watts
Any calculated power value below this cut-off will not be displayed. As well, the three-phase energy data will not accumu-
late if the total power from all three phases does not exceed the power cut-off.
Lower the VOLTAGE CUT-OFF LEVEL and CURRENT CUT-OFF LEVEL with care as the relay accepts lower signals
as valid measurements. Unless dictated otherwise by a specific application, the default settings of “0.02
NOTE
pu” for CURRENT CUT-OFF LEVEL and “1.0 V” for VOLTAGE CUT-OFF LEVEL are recommended.
Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program-
mable pushbuttons to clear specific records are typical applications for these commands. Since the T60 responds to rising
edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
Clearing records with user-programmable operands is not protected by the command password. However, user-program-
mable pushbuttons are protected by the command password. Thus, if they are used to clear records, the user-programma-
ble pushbuttons can provide extra security if required.
For example, to assign user-programmable pushbutton 1 to clear demand records, the following settings should be applied.

The T60 is equipped with up to three independent serial communication ports. The faceplate RS232 port is intended for
local use and is fixed at 19200 baud and no parity. The rear COM1 port type is selected when ordering: either an Ethernet
or RS485 port. The rear COM2 port be used for either RS485 or RRTD communications.

5 It is important that the baud rate and parity settings agree with the settings used on the computer or other equipment that is
connected to these ports.
The RS485 ports may be connected to a computer running EnerVista UR Setup. This software can download and upload
setting files, view measured parameters, and upgrade the relay firmware. A maximum of 32 relays can be daisy-chained
and connected to a DCS, PLC or PC using the RS485 ports.
The baud rate for standard RS485 communications can be selected as 300, 1200, 2400, 4800, 9600, 14400, 19200,
28800, 33600, 38400, 57600, or 115200 bps.
For each RS485 port, the minimum time before the port will transmit after receiving data from a host can be
set. This feature allows operation with hosts which hold the RS485 transmitter active for some time after
NOTE
each transmission.
If the COM2 USAGE setting is “RRTD”, then the COM2 port is used to monitor the RTDs on a remote RTD unit. The remote
RTD unit uses the Modbus RTU protocol over RS485. The RRTD device must have a unique address from 1 to 254. The
baud rate for RRTD communications can be selected as 300, 1200, 2400, 4800, 9600, 14400, or 19200 bps.
If the RS485 COM2 port is used for an RRTD, then there must not be any other devices connected in the daisy-chain for
any other purpose. The port is strictly dedicated to RRTD usage when COM2 USAGE is selected as “RRTD”.
Power must be cycled to the T60 for changes to the COM2 USAGE setting to take effect.
NOTE
c) NETWORK
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS NETWORK
These messages appear only if the T60 is ordered with an Ethernet card.
The IP addresses are used with the DNP, Modbus/TCP, IEC 61580, IEC 60870-5-104, TFTP, and HTTP protocols. The
NSAP address is used with the IEC 61850 protocol over the OSI (CLNP/TP4) stack only. Each network protocol has a set-
ting for the TCP/UDP port number. These settings are used only in advanced network configurations and should normally
be left at their default values, but may be changed if required (for example, to allow access to multiple UR-series relays
behind a router). By setting a different TCP/UDP PORT NUMBER for a given protocol on each UR-series relay, the router can
map the relays to the same external IP address. The client software (EnerVista UR Setup, for example) must be configured
to use the correct port number if these settings are used.
When the NSAP address, any TCP/UDP port number, or any user map setting (when used with DNP) is changed, it
will not become active until power to the relay has been cycled (off-on). 5
NOTE
Do not set more than one protocol to the same TCP/UDP PORT NUMBER, as this will result in unreliable opera-
tion of those protocols.
WARNING
d) MODBUS PROTOCOL
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS MODBUS PROTOCOL
The serial communication ports utilize the Modbus protocol, unless configured for DNP or IEC 60870-5-104 operation (see
descriptions below). This allows the EnerVista UR Setup software to be used. The UR operates as a Modbus slave device
only. When using Modbus protocol on the RS232 port, the T60 will respond regardless of the MODBUS SLAVE ADDRESS pro-
grammed. For the RS485 ports each T60 must have a unique address from 1 to 254. Address 0 is the broadcast address
which all Modbus slave devices listen to. Addresses do not have to be sequential, but no two devices can have the same
address or conflicts resulting in errors will occur. Generally, each device added to the link should use the next higher
address starting at 1. Refer to Appendix B for more information on the Modbus protocol.
Changes to the MODBUS TCP PORT NUMBER setting will not take effect until the T60 is restarted.
NOTE
e) DNP PROTOCOL
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS DNP PROTOCOL
The T60 supports the Distributed Network Protocol (DNP) version 3.0. The T60 can be used as a DNP slave device con-
nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the T60 maintains two sets of DNP
data change buffers and connection information, two DNP masters can actively communicate with the T60 at one time.
The IEC 60870-5-104 and DNP protocols cannot be simultaneously. When the IEC 60870-5-104 FUNCTION set-
ting is set to “Enabled”, the DNP protocol will not be operational. When this setting is changed it will not
NOTE
become active until power to the relay has been cycled (off-to-on).
The DNP Channels sub-menu is shown below.
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS DNP PROTOCOL DNP CHANNELS

The DNP CHANNEL 1 PORT and DNP CHANNEL 2 PORT settings select the communications port assigned to the DNP protocol
for each channel. Once DNP is assigned to a serial port, the Modbus protocol is disabled on that port. Note that COM1 can
be used only in non-Ethernet UR relays. When this setting is set to “Network - TCP”, the DNP protocol can be used over
TCP/IP on channels 1 or 2. When this value is set to “Network - UDP”, the DNP protocol can be used over UDP/IP on chan-
nel 1 only. Refer to Appendix E for additional information on the DNP protocol.
Changes to the DNP CHANNEL 1 PORT and DNP CHANNEL 2 PORT settings will take effect only after power has
been cycled to the relay.
NOTE
The DNP NETWORK CLIENT ADDRESS settings can force the T60 to respond to a maximum of five specific DNP masters. The
settings in this sub-menu are shown below.
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS DNP PROTOCOL DNP NETWORK CLIENT ADDRESSES
The DNP UNSOL RESPONSE FUNCTION should be “Disabled” for RS485 applications since there is no collision avoidance
mechanism. The DNP UNSOL RESPONSE TIMEOUT sets the time the T60 waits for a DNP master to confirm an unsolicited
response. The DNP UNSOL RESPONSE MAX RETRIES setting determines the number of times the T60 retransmits an unsolic-
ited response without receiving confirmation from the master; a value of “255” allows infinite re-tries. The DNP UNSOL
RESPONSE DEST ADDRESS is the DNP address to which all unsolicited responses are sent. The IP address to which unsolic-
ited responses are sent is determined by the T60 from the current TCP connection or the most recent UDP message.
The DNP scale factor settings are numbers used to scale analog input point values. These settings group the T60 analog
input data into the following types: current, voltage, power, energy, power factor, and other. Each setting represents the
scale factor for all analog input points of that type. For example, if the DNP VOLTAGE SCALE FACTOR setting is set to “1000”,
all DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000
5 V on the T60 will be returned as 72). These settings are useful when analog input values must be adjusted to fit within cer-
tain ranges in DNP masters. Note that a scale factor of 0.1 is equivalent to a multiplier of 10 (that is, the value will be 10
times larger).
The DNP DEFAULT DEADBAND settings determine when to trigger unsolicited responses containing analog input data. These
settings group the T60 analog input data into the following types: current, voltage, power, energy, power factor, and other.
Each setting represents the default deadband value for all analog input points of that type. For example, to trigger unsolic-
ited responses from the T60 when any current values change by 15 A, the DNP CURRENT DEFAULT DEADBAND setting should
be set to “15”. Note that these settings are the deadband default values. DNP object 34 points can be used to change dead-
band values, from the default, for each individual DNP analog input point. Whenever power is removed and re-applied to
the T60, the default deadbands will be in effect.
The DNP TIME SYNC IIN PERIOD setting determines how often the Need Time Internal Indication (IIN) bit is set by the T60.
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
The DNP MESSAGE FRAGMENT SIZE setting determines the size, in bytes, at which message fragmentation occurs. Large
fragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to be
necessary which can provide for more robust data transfer over noisy communication channels.
When the DNP data points (analog inputs and/or binary inputs) are configured for Ethernet-enabled relays,
check the “DNP Points Lists” T60 web page to view the points lists. This page can be viewed with a web
NOTE
browser by entering the T60 IP address to access the T60 “Main Menu”, then by selecting the “Device Infor-
mation Menu” > “DNP Points Lists” menu item.
The DNP OBJECT 1 DEFAULT VARIATION to DNP OBJECT 32 DEFAULT VARIATION settings allow the user to select the DNP
default variation number for object types 1, 2, 20, 21, 22, 23, 30, and 32. The default variation refers to the variation
response when variation 0 is requested and/or in class 0, 1, 2, or 3 scans. Refer to the DNP implementation section in
appendix E for additional details.
The DNP binary outputs typically map one-to-one to IED data points. That is, each DNP binary output controls a single
physical or virtual control point in an IED. In the T60 relay, DNP binary outputs are mapped to virtual inputs. However, some
legacy DNP implementations use a mapping of one DNP binary output to two physical or virtual control points to support
the concept of trip/close (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is, the DNP
master can operate a single point for both trip and close, or raise and lower, operations. The T60 can be configured to sup-
port paired control points, with each paired control point operating two virtual inputs. The DNP NUMBER OF PAIRED CONTROL
POINTS setting allows configuration of from 0 to 32 binary output paired controls. Points not configured as paired operate on
a one-to-one basis.
The DNP ADDRESS setting is the DNP slave address. This number identifies the T60 on a DNP communications link. Each
DNP slave should be assigned a unique address.
The DNP TCP CONNECTION TIMEOUT setting specifies a time delay for the detection of dead network TCP connections. If
there is no data traffic on a DNP TCP connection for greater than the time specified by this setting, the connection will be
aborted by the T60. This frees up the connection to be re-used by a client.
Relay power must be re-cycled after changing the DNP TCP CONNECTION TIMEOUT setting for the changes to take
effect.
NOTE
The binary and analog inputs points for the DNP protocol, or the MSP and MME points for IEC 60870-5-104 protocol, can
configured to a maximum of 256 points. The value for each point is user-programmable and can be configured by assigning
FlexLogic™ operands for binary inputs / MSP points or FlexAnalog parameters for analog inputs / MME points.
The menu for the binary input points (DNP) or MSP points (IEC 60870-5-104) is shown below.

Up to 256 binary input points can be configured for the DNP or IEC 60870-5-104 protocols. The points are configured by
assigning an appropriate FlexLogic™ operand. Refer to the Introduction to FlexLogic™ section in this chapter for the full
range of assignable operands.
The menu for the analog input points (DNP) or MME points (IEC 60870-5-104) is shown below.

Up to 256 analog input points can be configured for the DNP or IEC 60870-5-104 protocols. The analog point list is config-
ured by assigning an appropriate FlexAnalog parameter to each point. Refer to Appendix A: FlexAnalog Parameters for the
full range of assignable parameters.
The DNP / IEC 60870-5-104 point lists always begin with point 0 and end at the first “Off” value. Since DNP /
IEC 60870-5-104 point lists must be in one continuous block, any points assigned after the first “Off” point
NOTE are ignored.
Changes to the DNP / IEC 60870-5-104 point lists will not take effect until the T60 is restarted.
NOTE
The T60 Transformer Protection System is provided with optional IEC 61850 communications capability.
This feature is specified as a software option at the time of ordering. Refer to the Ordering section of chap-
ter 2 for additional details. The IEC 61850 protocol features are not available if CPU type E is ordered.
The T60 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported
over two protocol stacks: TCP/IP over ethernet and TP4/CLNP (OSI) over ethernet. The T60 operates as an IEC 61850
server. The Remote inputs and outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.
The GSSE/GOOSE configuration main menu is divided into two areas: transmission and reception.

setting controls the steady-state heartbeat time interval.
The DEFAULT GSSE/GOOSE UPDATE TIME setting is applicable to GSSE, fixed T60 GOOSE, and configurable GOOSE.

These settings are applicable to GSSE only. If the fixed GOOSE function is enabled, GSSE messages are not transmitted.
The GSSE ID setting represents the IEC 61850 GSSE application ID name string sent as part of each GSSE message. This
string identifies the GSSE message to the receiving device. In T60 releases previous to 5.0x, this name string was repre-
sented by the RELAY NAME setting.
The details about each scheme are shown in the following table.
The configurable GOOSE feature is recommended for applications that require GOOSE data transfer between UR-series
IEDs and devices from other manufacturers. Fixed GOOSE is recommended for applications that require GOOSE data
transfer between UR-series IEDs.
IEC 61850 GOOSE messaging contains a number of configurable parameters, all of which must be correct to achieve the
successful transfer of data. It is critical that the configured datasets at the transmission and reception devices are an exact
match in terms of data structure, and that the GOOSE addresses and name strings match exactly. Manual configuration is
possible, but third-party substation configuration software may be used to automate the process. The EnerVista UR Setup
software can produce IEC 61850 ICD files and import IEC 61850 SCD files produced by a substation configurator (refer to
the IEC 61850 IED configuration section later in this appendix).
The following example illustrates the configuration required to transfer IEC 61850 data items between two devices. The
general steps required for transmission configuration are:
1. Configure the transmission dataset.
2. Configure the GOOSE service settings.
3. Configure the data.
The general steps required for reception configuration are:
1. Configure the reception dataset.
2. Configure the GOOSE service settings.
3. Configure the data.
This example shows how to configure the transmission and reception of three IEC 61850 data items: a single point status
value, its associated quality flags, and a floating point analog value.
The following procedure illustrates the transmission configuration.
1. Configure the transmission dataset by making the following changes in the PRODUCT SETUP COMMUNICATION
IEC 61850 PROTOCOL GSSE/GOOSE CONFIGURATION TRANSMISSION CONFIGURABLE GOOSE CONFIGURABLE
GOOSE 1 CONFIG GSE 1 DATASET ITEMS settings menu:
– Set ITEM 1 to “GGIO1.ST.Ind1.q” to indicate quality flags for GGIO1 status indication 1.
– Set ITEM 2 to “GGIO1.ST.Ind1.stVal” to indicate the status value for GGIO1 status indication 1.
– Set ITEM 3 to “MMXU1.MX.Hz.mag.f” to indicate the analog frequency magnitude for MMXU1 (the metered fre-
quency for SRC1).
The transmission dataset now contains a quality flag, a single point status Boolean value, and a floating point analog
value. The reception dataset on the receiving device must exactly match this structure.
2. Configure the GOOSE service settings by making the following changes in the PRODUCT SETUP COMMUNICATION
IEC 61850 PROTOCOL GSSE/GOOSE CONFIGURATION TRANSMISSION CONFIGURABLE GOOSE CONFIGU-
RABLE GOOSE 1 settings menu:
– Set ITEM 1 to “GGIO3.ST.Ind1.q” to indicate quality flags for GGIO3 status indication 1.
– Set ITEM 2 to “GGIO3.ST.Ind1.stVal” to indicate the status value for GGIO3 status indication 1.
– Set ITEM 3 to “GGIO3.MX.AnIn1.mag.f” to indicate the analog magnitude for GGIO3 analog input 1.
The reception dataset now contains a quality flag, a single point status Boolean value, and a floating point analog
value. This matches the transmission dataset configuration above.
2. Configure the GOOSE service settings by making the following changes in the INPUTS/OUTPUTS REMOTE DEVICES
REMOTE DEVICE 1 settings menu:
– Set REMOTE DEVICE 1 ID to match the GOOSE ID string for the transmitting device. Enter “GOOSEOut_1”.
– Set REMOTE DEVICE 1 ETYPE APPID to match the ETHERTYPE application ID from the transmitting device. This is
“0” in the example above.
– Set the REMOTE DEVICE 1 DATASET value. This value represents the dataset number in use. Since we are using
configurable GOOSE 1 in this example, program this value as “GOOSEIn 1”.
3. Configure the Boolean data by making the following changes in the INPUTS/OUTPUTS REMOTE INPUTS REMOTE
INPUT 1settings menu:
– Set REMOTE IN 1 DEVICE to “GOOSEOut_1”.
– Set REMOTE IN 1 ITEM to “Dataset Item 2”. This assigns the value of the GGIO3.ST.Ind1.stVal single point status
item to remote input 1.
4. Configure the analog data by making the following changes in the INPUTS/OUTPUTS IEC 61850 GOOSE ANALOG
INPUTS settings menu:
– Set the IEC61850 GOOSE ANALOG INPUT 1 DEFAULT VALUE to “60.000”.
– Enter “Hz” for the IEC61850 GOOSE ANALOG INPUT 1 UNITS setting.
The GOOSE analog input 1 can now be used as a FlexAnalog™ value in a FlexElement™ or in other settings. The T60
must be rebooted (control power removed and re-applied) before these settings take effect.
The value of GOOSE analog input 1 in the receiving device will be determined by the MMXU1.MX.Hz.mag.f value in the
sending device. This MMXU value is determined by the source 1 frequency value and the MMXU Hz deadband setting of
the sending device.
Remote input 1 can now be used in FlexLogic™ equations or other settings. The T60 must be rebooted (control power
removed and re-applied) before these settings take effect.
The value of remote input 1 (Boolean on or off) in the receiving device will be determined by the GGIO1.ST.Ind1.stVal value
5 in the sending device. The above settings will be automatically populated by the EnerVista UR Setup software when a com-
plete SCD file is created by third party substation configurator software.
For intercommunication between T60 IEDs, the fixed (DNA/UserSt) dataset can be used. The DNA/UserSt dataset contains
the same DNA and UserSt bit pairs that are included in GSSE messages. All GOOSE messages transmitted by the T60
(DNA/UserSt dataset and configurable datasets) use the IEC 61850 GOOSE messaging services (for example, VLAN sup-
port).
Set the CONFIG GSE 1 FUNCTION function to “Disabled” when configuration changes are required. Once changes are
entered, return the CONFIG GSE 1 FUNCTION to “Enabled” and restart the unit for changes to take effect.

To create a configurable GOOSE dataset that contains an IEC 61850 Single Point Status indication and its associated qual-
ity flags, the following dataset items can be selected: “GGIO1.ST.Ind1.stVal” and “GGIO1.ST.Ind1.q”. The T60 will then cre-
ate a dataset containing these two data items. The status value for GGIO1.ST.Ind1.stVal is determined by the FlexLogic™
operand assigned to GGIO1 indication 1. Changes to this operand will result in the transmission of GOOSE messages con-
taining the defined dataset.

The configurable GOOSE settings allow the T60 to be configured to receive a number of different datasets within IEC
61850 GOOSE messages. Up to sixteen different configurable datasets can be configured for reception. This is useful for
intercommunication between T60 IEDs and devices from other manufacturers that support IEC 61850.
For intercommunication between T60 IEDs, the fixed (DNA/UserSt) dataset can be used. The DNA/UserSt dataset contains
the same DNA and UserSt bit pairs that are included in GSSE messages.
To set up a T60 to receive a configurable GOOSE dataset that contains two IEC 61850 single point status indications, the
following dataset items can be selected (for example, for configurable GOOSE dataset 1): “GGIO3.ST.Ind1.stVal” and
“GGIO3.ST.Ind2.stVal”. The T60 will then create a dataset containing these two data items. The Boolean status values from
these data items can be utilized as remote input FlexLogic™ operands. First, the REMOTE DEVICE 1(16) DATASET setting 5
must be set to contain dataset “GOOSEIn 1” (that is, the first configurable dataset). Then REMOTE IN 1(16) ITEM settings
must be set to “Dataset Item 1” and “Dataset Item 2”. These remote input FlexLogic™ operands will then change state in
accordance with the status values of the data items in the configured dataset.
Double-point status values may be included in the GOOSE dataset. Received values are populated in the
GGIO3.ST.IndPos1.stVal and higher items.
Floating point analog values originating from MMXU logical nodes may be included in GOOSE datasets. Deadband (non-
instantaneous) values can be transmitted. Received values are used to populate the GGIO3.MX.AnIn1 and higher items.
Received values are also available as FlexAnalog™ parameters (GOOSE analog In1 and up).
GGIO3.MX.AnIn1 to GGIO3.MX.AnIn32 can only be used once for all sixteen reception datasets.

PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS IEC 61850 PROTOCOL SERVER CONFIGURATION
The IED NAME and LD INST settings represent the MMS domain name (IEC 61850 logical device) where all IEC/MMS logical
nodes are located. Valid characters for these values are upper and lowercase letters, numbers, and the underscore (_)
character, and the first character in the string must be a letter. This conforms to the IEC 61850 standard. The LOCATION is a
variable string and can be composed of ASCII characters. This string appears within the PhyName of the LPHD node.
The IEC/MMS TCP PORT NUMBER setting allows the user to change the TCP port number for MMS connections. The INCLUDE
NON-IEC DATA setting determines whether or not the “UR” MMS domain will be available. This domain contains a large num-
ber of UR-series specific data items that are not available in the IEC 61850 logical nodes. This data does not follow the IEC
61850 naming conventions. For communications schemes that strictly follow the IEC 61850 standard, this setting should be
“Disabled”.
The SERVER SCANNING feature should be set to “Disabled” when IEC 61850 client/server functionality is not required. IEC
61850 has two modes of functionality: GOOSE/GSSE inter-device communication and client/server communication. If the
GOOSE/GSSE functionality is required without the IEC 61850 client server feature, then server scanning can be disabled
to increase CPU resources. When server scanning is disabled, there will be not updated to the IEC 61850 logical node sta-
tus values in the T60. Clients will still be able to connect to the server (T60 relay), but most data values will not be updated.
This setting does not affect GOOSE/GSSE operation.
Changes to the IED NAME setting, LD INST setting, and GOOSE dataset will not take effect until the T60 is restarted.

maximum value for each MMXU measured quantity, since this represents the 100.00% value for the deadband.
The minimum value for all quantities is 0; the maximum values are as follows:
• phase current: 46 phase CT primary setting
• neutral current: 46 ground CT primary setting
• voltage: 275 VT ratio setting
• power (real, reactive, and apparent): 46 phase CT primary setting 275 VT ratio setting

The GGIO5 logical node allows IEC 61850 client access to integer data values. This allows access to as many as 16
unsigned integer value points, associated timestamps, and quality flags. The method of configuration is similar to that of
GGIO1 (binary status values). The settings allow the selection of FlexInteger™ values for each GGIO5 integer value point.
It is intended that clients use GGIO5 to access generic integer values from the T60. Additional settings are provided to
allow the selection of the number of integer values available in GGIO5 (1 to 16), and to assign FlexInteger™ values to the
GGIO5 integer inputs. The following setting is available for all GGIO5 configuration points.
• GGIO5 UINT IN 1 VALUE: This setting selects the FlexInteger™ value to drive each GGIO5 integer status value

Since GSSE/GOOSE messages are multicast Ethernet by specification, they will not usually be forwarded by net-
work routers. However, GOOSE messages may be fowarded by routers if the router has been configured for VLAN
NOTE functionality.
The T60 contains an embedded web server and is capable of transferring web pages to a web browser such as Microsoft
Internet Explorer or Mozilla Firefox. This feature is available only if the T60 has the ethernet option installed. The web
pages are organized as a series of menus that can be accessed starting at the T60 “Main Menu”. Web pages are available
showing DNP and IEC 60870-5-104 points lists, Modbus registers, event records, fault reports, etc. The web pages can be
accessed by connecting the UR and a computer to an ethernet network. The main menu will be displayed in the web
browser on the computer simply by entering the IP address of the T60 into the “Address” box on the web browser.
i) TFTP PROTOCOL
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS TFTP PROTOCOL
The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the T60 over a network. The T60 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file
obtained from the T60 contains a list and description of all available files (event records, oscillography, etc.).
The T60 supports the IEC 60870-5-104 protocol. The T60 can be used as an IEC 60870-5-104 slave device connected to a
maximum of two masters (usually either an RTU or a SCADA master station). Since the T60 maintains two sets of IEC
60870-5-104 data change buffers, no more than two masters should actively communicate with the T60 at one time.
The IEC ------- DEFAULT THRESHOLD settings are used to determine when to trigger spontaneous responses containing
M_ME_NC_1 analog data. These settings group the T60 analog data into types: current, voltage, power, energy, and other.
Each setting represents the default threshold value for all M_ME_NC_1 analog points of that type. For example, to trigger
spontaneous responses from the T60 when any current values change by 15 A, the IEC CURRENT DEFAULT THRESHOLD set-
ting should be set to 15. Note that these settings are the default values of the deadbands. P_ME_NC_1 (parameter of mea-
sured value, short floating point value) points can be used to change threshold values, from the default, for each individual
M_ME_NC_1 analog point. Whenever power is removed and re-applied to the T60, the default thresholds will be in effect.
The IEC 60870-5-104 and DNP protocols cannot be used simultaneously. When the IEC 60870-5-104 FUNCTION
setting is set to “Enabled”, the DNP protocol will not be operational. When this setting is changed it will not
NOTE
become active until power to the relay has been cycled (off-to-on).
k) SNTP PROTOCOL
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS SNTP PROTOCOL
The T60 supports the Simple Network Time Protocol specified in RFC-2030. With SNTP, the T60 can obtain clock time over
an Ethernet network. The T60 acts as an SNTP client to receive time values from an SNTP/NTP server, usually a dedicated
product using a GPS receiver to provide an accurate time. Both unicast and broadcast SNTP are supported.
If SNTP functionality is enabled at the same time as IRIG-B, the IRIG-B signal provides the time value to the T60 clock for
as long as a valid signal is present. If the IRIG-B signal is removed, the time obtained from the SNTP server is used. If
either SNTP or IRIG-B is enabled, the T60 clock value cannot be changed using the front panel keypad.
To use SNTP in unicast mode, SNTP SERVER IP ADDR must be set to the SNTP/NTP server IP address. Once this address is
set and SNTP FUNCTION is “Enabled”, the T60 attempts to obtain time values from the SNTP/NTP server. Since many time
values are obtained and averaged, it generally takes three to four minutes until the T60 clock is closely synchronized with
the SNTP/NTP server. It may take up to two minutes for the T60 to signal an SNTP self-test error if the server is offline.
To use SNTP in broadcast mode, set the SNTP SERVER IP ADDR setting to “0.0.0.0” and SNTP FUNCTION to “Enabled”. The
T60 then listens to SNTP messages sent to the “all ones” broadcast address for the subnet. The T60 waits up to eighteen
minutes (>1024 seconds) without receiving an SNTP broadcast message before signaling an SNTP self-test error.
The UR-series relays do not support the multicast or anycast SNTP functionality. 5
l) EGD PROTOCOL
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS EGD PROTOCOL
The T60 Transformer Protection System is provided with optional Ethernet Global Data (EGD) communi-
cations capability. This feature is specified as a software option at the time of ordering. Refer to the Order-
ing section of chapter 2 for additional details. The Ethernet Global Data (EGD) protocol feature is not
available if CPU Type E is ordered.
The relay supports one fast Ethernet Global Data (EGD) exchange and two slow EGD exchanges. There are 20 data items
in the fast-produced EGD exchange and 50 data items in each slow-produced exchange.
Ethernet Global Data (EGD) is a suite of protocols used for the real-time transfer of data for display and control purposes.
The relay can be configured to ‘produce’ EGD data exchanges, and other devices can be configured to ‘consume’ EGD
data exchanges. The number of produced exchanges (up to three), the data items in each exchange (up to 50), and the
exchange production rate can be configured.
EGD cannot be used to transfer data between UR-series relays. The relay supports EGD production only. An EGD
exchange will not be transmitted unless the destination address is non-zero, and at least the first data item address is set to
a valid Modbus register address. Note that the default setting value of “0” is considered invalid.
The settings menu for the fast EGD exchange is shown below:
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS EGD PROTOCOL FAST PROD EXCH 1 CONFIGURATION
Fast exchanges (50 to 1000 ms) are generally used in control schemes. The T60 has one fast exchange (exchange 1) and
two slow exchanges (exchange 2 and 3).
5 The settings menu for the slow EGD exchanges is shown below:
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS EGD PROTOCOL SLOW PROD EXCH 1(2) CONFIGURATION
Slow EGD exchanges (500 to 1000 ms) are generally used for the transfer and display of data items. The settings for the
fast and slow exchanges are described below:
• EXCH 1 DESTINATION: This setting specifies the destination IP address of the produced EGD exchange. This is usu-
ally unicast or broadcast.
• EXCH 1 DATA RATE: This setting specifies the rate at which this EGD exchange is transmitted. If the setting is 50 ms,
the exchange data will be updated and sent once every 50 ms. If the setting is 1000 ms, the exchange data will be
updated and sent once per second. EGD exchange 1 has a setting range of 50 to 1000 ms. Exchanges 2 and 3 have a
setting range of 500 to 1000 ms.
• EXCH 1 DATA ITEM 1 to 20/50: These settings specify the data items that are part of this EGD exchange. Almost any
data from the T60 memory map can be configured to be included in an EGD exchange. The settings are the starting
Modbus register address for the data item in decimal format. Refer to Appendix B for the complete Modbus memory
map. Note that the Modbus memory map displays shows addresses in hexadecimal format. as such, it will be neces-
sary to convert these values to decimal format before entering them as values for these setpoints.
To select a data item to be part of an exchange, it is only necessary to choose the starting Modbus address of the item.
That is, for items occupying more than one Modbus register (for example, 32 bit integers and floating point values),
only the first Modbus address is required. The EGD exchange configured with these settings contains the data items
up to the first setting that contains a Modbus address with no data, or 0. That is, if the first three settings contain valid
Modbus addresses and the fourth is 0, the produced EGD exchange will contain three data items.
m) ETHERNET SWITCH
PATH: SETTINGS PRODUCT SETUP COMMUNICATIONS ETHERNET SWITCH
These settings appear only if the T60 is ordered with an Ethernet switch module (type 2S or 2T).
The IP address and Modbus TCP port number for the Ethernet switch module are specified in this menu. These settings
are used in advanced network configurations. Please consult the network administrator before making changes to these
settings. The client software (EnerVista UR Setup, for example) is the preferred interface to configure these settings.
The PORT 1 EVENTS through PORT 6 EVENTS settings allow Ethernet switch module events to be logged in the event
recorder.
The Modbus user map provides read-only access for up to 256 registers. To obtain a memory map value, enter the desired
address in the ADDRESS line (this value must be converted from hex to decimal format). The corresponding value is dis-
played in the VALUE line. A value of “0” in subsequent register ADDRESS lines automatically returns values for the previous
ADDRESS lines incremented by “1”. An address value of “0” in the initial register means “none” and values of “0” will be dis-
played for all registers. Different ADDRESS values can be entered as required in any of the register positions.

The date and time can be synchronized a known time base and to other relays using an IRIG-B signal. It has the same
accuracy as an electronic watch, approximately ±1 minute per month. If an IRIG-B signal is connected to the relay, only the
current year needs to be entered. See the COMMANDS SET DATE AND TIME menu to manually set the relay clock.
The REAL TIME CLOCK EVENTS setting allows changes to the date and/or time to be captured in the event record.
The LOCAL TIME OFFSET FROM UTC setting is used to specify the local time zone offset from Universal Coordinated Time
(Greenwich Mean Time) in hours. This setting has two uses. When the T60 is time synchronized with IRIG-B, or has no per-
manent time synchronization, the offset is used to calculate UTC time for IEC 61850 features. When the T60 is time syn-
chronized with SNTP, the offset is used to determine the local time for the T60 clock, since SNTP provides UTC time.
The daylight savings time (DST) settings can be used to allow the T60 clock can follow the DST rules of the local time zone.
Note that when IRIG-B time synchronization is active, the DST settings are ignored. The DST settings are used when the
T60 is synchronized with SNTP, or when neither SNTP nor IRIG-B is used.
Only timestamps in the event recorder and communications protocols are affected by the daylight savings time set-
tings. The reported real-time clock value does not change.

PATH: SETTINGS PRODUCT SETUP USER-PROGRAMMABLE FAULT REPORT USER-PROGRAMMABLE FAULT REPORT 1(2)
FAULT REPORT 1 #32: Range: Off, any actual value analog parameter
MESSAGE
Off
When enabled, this function monitors the pre-fault trigger. The pre-fault data are stored in the memory for prospective cre-
ation of the fault report on the rising edge of the pre-fault trigger. The element waits for the fault trigger as long as the pre-
fault trigger is asserted, but not shorter than 1 second. When the fault trigger occurs, the fault data is stored and the com- 5
plete report is created. If the fault trigger does not occur within 1 second after the pre-fault trigger drops out, the element
resets and no record is created.
The user programmable record contains the following information: the user-programmed relay name, detailed firmware
revision (5.9x, for example) and relay model (T60), the date and time of trigger, the name of pre-fault trigger (a specific
FlexLogic™ operand), the name of fault trigger (a specific FlexLogic™ operand), the active setting group at pre-fault trig-
ger, the active setting group at fault trigger, pre-fault values of all programmed analog channels (one cycle before pre-fault
trigger), and fault values of all programmed analog channels (at the fault trigger).
The report includes fault duration times for each of the breakers (created by the breaker arcing current feature). To include
fault duration times in the fault report, the user must enable and configure breaker arcing current feature for each of the
breakers. Fault duration is reported on a per-phase basis.
Each fault report is stored as a file to a maximum capacity of ten files. An eleventh trigger overwrites the oldest file. The
EnerVista UR Setup software is required to view all captured data. A FAULT RPT TRIG event is automatically created when
the report is triggered.
The relay includes two user-programmable fault reports to enable capture of two types of trips (for example, trip from ther-
mal protection with the report configured to include temperatures, and short-circuit trip with the report configured to include
voltages and currents). Both reports feed the same report file queue.
The last record is available as individual data items via communications protocols.
• PRE-FAULT 1 TRIGGER: Specifies the FlexLogic™ operand to capture the pre-fault data. The rising edge of this
operand stores one cycle-old data for subsequent reporting. The element waits for the fault trigger to actually create a
record as long as the operand selected as PRE-FAULT 1 TRIGGER is “On”. If the operand remains “Off” for 1 second, the
element resets and no record is created.
• FAULT 1 TRIGGER: Specifies the FlexLogic™ operand to capture the fault data. The rising edge of this operand
stores the data as fault data and results in a new report. The trigger (not the pre-fault trigger) controls the date and time
of the report.
• FAULT REPORT 1 #1 to FAULT REPORT 1 #32: These settings specify an actual value such as voltage or current
magnitude, true RMS, phase angle, frequency, temperature, etc., to be stored should the report be created. Up to 32
channels can be configured. Two reports are configurable to cope with variety of trip conditions and items of interest.
5.2.8 OSCILLOGRAPHY
a) MAIN MENU
PATH: SETTINGS PRODUCT SETUP OSCILLOGRAPHY
Oscillography records contain waveforms captured at the sampling rate as well as other relay data at the point of trigger.
Oscillography records are triggered by a programmable FlexLogic™ operand. Multiple oscillography records may be cap-
5 tured simultaneously.
The NUMBER OF RECORDS is selectable, but the number of cycles captured in a single record varies considerably based on
other factors such as sample rate and the number of operational modules. There is a fixed amount of data storage for oscil-
lography; the more data captured, the less the number of cycles captured per record. See the ACTUAL VALUES
RECORDS OSCILLOGRAPHY menu to view the number of cycles captured per record. The following table provides sam-
ple configurations with corresponding cycles/record.
A new record may automatically overwrite an older record if TRIGGER MODE is set to “Automatic Overwrite”.
Set the TRIGGER POSITION to a percentage of the total buffer size (for example, 10%, 50%, 75%, etc.). A trigger position of
25% consists of 25% pre- and 75% post-trigger data. The TRIGGER SOURCE is always captured in oscillography and may be
any FlexLogic™ parameter (element state, contact input, virtual output, etc.). The relay sampling rate is 64 samples per
cycle.
The AC INPUT WAVEFORMS setting determines the sampling rate at which AC input signals (that is, current and voltage) are
stored. Reducing the sampling rate allows longer records to be stored. This setting has no effect on the internal sampling
rate of the relay which is always 64 samples per cycle; that is, it has no effect on the fundamental calculations of the device.
When changes are made to the oscillography settings, all existing oscillography records will be CLEARED.

These settings select the metering actual value recorded in an oscillography trace. The length of each oscillography trace
depends in part on the number of parameters selected here. Parameters set to “Off” are ignored. The parameters available
in a given relay are dependent on:
• The type of relay,
• The type and number of CT/VT hardware modules installed, and
• The type and number of analog input hardware modules installed.
Upon startup, the relay will automatically prepare the parameter list. A list of all possible analog metering actual value
parameters is presented in Appendix A: FlexAnalog parameters. The parameter index number shown in any of the tables is
used to expedite the selection of the parameter on the relay display. It can be quite time-consuming to scan through the list
of parameters via the relay keypad and display - entering this number via the relay keypad will cause the corresponding
parameter to be displayed.
All eight CT/VT module channels are stored in the oscillography file. The CT/VT module channels are named as follows:
<slot_letter><terminal_number>—<I or V><phase A, B, or C, or 4th input>
The fourth current input in a bank is called IG, and the fourth voltage input in a bank is called VX. For example, F2-IB desig-
nates the IB signal on terminal 2 of the CT/VT module in slot F.
If there are no CT/VT modules and analog input modules, no analog traces will appear in the file; only the digital traces will
appear.
The source harmonic indices appear as oscillography analog channels numbered from 0 to 23. These correspond
directly to the to the 2nd to 25th harmonics in the relay as follows:

The data logger samples and records up to 16 analog parameters at a user-defined sampling rate. This recorded data may

All data is stored in non-volatile memory, meaning that the information is retained when power to the relay is lost.
For a fixed sampling rate, the data logger can be configured with a few channels over a long period or a larger number of
channels for a shorter period. The relay automatically partitions the available memory between the channels in use. Exam-
ple storage capacities for a system frequency of 60 Hz are shown in the following table.
Changing any setting affecting data logger operation will clear any data that is currently in the log.
NOTE
• DATA LOGGER MODE: This setting configures the mode in which the data logger will operate. When set to “Continu-
ous”, the data logger will actively record any configured channels at the rate as defined by the DATA LOGGER RATE. The
5
data logger will be idle in this mode if no channels are configured. When set to “Trigger”, the data logger will begin to
record any configured channels at the instance of the rising edge of the DATA LOGGER TRIGGER source FlexLogic™
operand. The data logger will ignore all subsequent triggers and will continue to record data until the active record is
full. Once the data logger is full a CLEAR DATA LOGGER command is required to clear the data logger record before a
new record can be started. Performing the CLEAR DATA LOGGER command will also stop the current record and reset
the data logger to be ready for the next trigger.
• DATA LOGGER TRIGGER: This setting selects the signal used to trigger the start of a new data logger record. Any
FlexLogic™ operand can be used as the trigger source. The DATA LOGGER TRIGGER setting only applies when the
mode is set to “Trigger”.
• DATA LOGGER RATE: This setting selects the time interval at which the actual value data will be recorded.
• DATA LOGGER CHNL 1(16): This setting selects the metering actual value that is to be recorded in Channel 1(16) of

5.2.10 DEMAND
The relay measures current demand on each phase, and three-phase demand for real, reactive, and apparent power. Cur-
rent and Power methods can be chosen separately for the convenience of the user. Settings are provided to allow the user
to emulate some common electrical utility demand measuring techniques, for statistical or control purposes. If the CRNT
DEMAND METHOD is set to "Block Interval" and the DEMAND TRIGGER is set to “Off”, Method 2 is used (see below). If
DEMAND TRIGGER is assigned to any other FlexLogic™ operand, Method 2a is used (see below).
The relay can be set to calculate demand by any of three methods as described below:
CALCULATION METHOD 1: THERMAL EXPONENTIAL
This method emulates the action of an analog peak recording thermal demand meter. The relay measures the quantity
(RMS current, real power, reactive power, or apparent power) on each phase every second, and assumes the circuit quan-
5 tity remains at this value until updated by the next measurement. It calculates the 'thermal demand equivalent' based on the
following equation:
– kt
dt = D1 – e (EQ 5.6)
where: d = demand value after applying input quantity for time t (in minutes)
D = input quantity (constant), and k = 2.3 / thermal 90% response time.
The 90% thermal response time characteristic of 15 minutes is illustrated below. A setpoint establishes the time to reach
90% of a steady-state value, just as the response time of an analog instrument. A steady state value applied for twice the
response time will indicate 99% of the value.
Demand (%)
If no trigger is assigned in the DEMAND TRIGGER setting and the CRNT DEMAND METHOD is "Block Interval", use cal-
culating method #2. If a trigger is assigned, the maximum allowed time between 2 trigger signals is 60 minutes. If
NOTE
no trigger signal appears within 60 minutes, demand calculations are performed and available and the algorithm
resets and starts the new cycle of calculations. The minimum required time for trigger contact closure is 20 s.
CALCULATION METHOD 3: ROLLING DEMAND
This method calculates a linear average of the quantity (RMS current, real power, reactive power, or apparent power) over
the programmed demand time interval, in the same way as Block Interval. The value is updated every minute and indicates
the demand over the time interval just preceding the time of update.

b) LED TEST
PATH: SETTINGS PRODUCT SETUP USER-PROGRAMMABLE LEDS LED TEST
When enabled, the LED test can be initiated from any digital input or user-programmable condition such as user-program-
mable pushbutton. The control operand is configured under the LED TEST CONTROL setting. The test covers all LEDs,
including the LEDs of the optional user-programmable pushbuttons.
The test consists of three stages.
1. All 62 LEDs on the relay are illuminated. This is a quick test to verify if any of the LEDs is “burned”. This stage lasts as
long as the control input is on, up to a maximum of 1 minute. After 1 minute, the test will end.
2. All the LEDs are turned off, and then one LED at a time turns on for 1 second, then back off. The test routine starts at
the top left panel, moving from the top to bottom of each LED column. This test checks for hardware failures that lead
to more than one LED being turned on from a single logic point. This stage can be interrupted at any time.
3. All the LEDs are turned on. One LED at a time turns off for 1 second, then back on. The test routine starts at the top left
panel moving from top to bottom of each column of the LEDs. This test checks for hardware failures that lead to more
than one LED being turned off from a single logic point. This stage can be interrupted at any time.
When testing is in progress, the LEDs are controlled by the test sequence, rather than the protection, control, and monitor-
ing features. However, the LED control mechanism accepts all the changes to LED states generated by the relay and
stores the actual LED states (on or off) in memory. When the test completes, the LEDs reflect the actual state resulting from
relay response during testing. The reset pushbutton will not clear any targets when the LED Test is in progress.
A dedicated FlexLogic™ operand, LED TEST IN PROGRESS, is set for the duration of the test. When the test sequence is ini-
tiated, the LED TEST INITIATED event is stored in the event recorder.
The entire test procedure is user-controlled. In particular, stage 1 can last as long as necessary, and stages 2 and 3 can be
interrupted. The test responds to the position and rising edges of the control input defined by the LED TEST CONTROL set-
ting. The control pulses must last at least 250 ms to take effect. The following diagram explains how the test is executed.

Configure the LED test to recognize user-programmable pushbutton 1 by making the following entries in the SETTINGS
PRODUCT SETUP USER-PROGRAMMABLE LEDS LED TEST menu:
The test will be initiated when the user-programmable pushbutton 1 is pressed. The pushbutton should remain pressed for
as long as the LEDs are being visually inspected. When finished, the pushbutton should be released. The relay will then
automatically start stage 2. At this point forward, test may be aborted by pressing the pushbutton.
APPLICATION EXAMPLE 2:
Assume one needs to check if any LEDs are “burned” as well as exercise one LED at a time to check for other failures. This
is to be performed via user-programmable pushbutton 1.
After applying the settings in application example 1, hold down the pushbutton as long as necessary to test all LEDs. Next,
release the pushbutton to automatically start stage 2. Once stage 2 has started, the pushbutton can be released. When
stage 2 is completed, stage 3 will automatically start. The test may be aborted at any time by pressing the pushbutton.

The trip and alarm LEDs are in the first LED column (enhanced faceplate) and on LED panel 1 (standard faceplate). Each
indicator can be programmed to become illuminated when the selected FlexLogic™ operand is in the logic 1 state.
There are 48 amber LEDs across the relay faceplate LED panels. Each of these indicators can be programmed to illumi-
nate when the selected FlexLogic™ operand is in the logic 1 state.
For the standard faceplate, the LEDs are located as follows.

• LED Panel 2: user-programmable LEDs 1 through 24
• LED Panel 3: user programmable LEDs 25 through 48
For the enhanced faceplate, the LEDs are located as follows.
• LED column 2: user-programmable LEDs 1 through 12
• LED column 3: user-programmable LEDs 13 through 24
• LED column 4: user-programmable LEDs 25 through 36
• LED column 5: user-programmable LEDs 37 through 48
Refer to the LED indicators section in chapter 4 for additional information on the location of these indexed LEDs.
The user-programmable LED settings select the FlexLogic™ operands that control the LEDs. If the LED 1 TYPE setting is
“Self-Reset” (the default setting), the LED illumination will track the state of the selected LED operand. If the LED 1 TYPE set-
ting is “Latched”, the LED, once lit, remains so until reset by the faceplate RESET button, from a remote device via a com-
munications channel, or from any programmed operand, even if the LED operand state de-asserts.
Refer to the Control of setting groups example in the Control elements section of this chapter for group activation.

All major self-test alarms are reported automatically with their corresponding FlexLogic™ operands, events, and targets.
Most of the minor alarms can be disabled if desired.
When in the “Disabled” mode, minor alarms will not assert a FlexLogic™ operand, write to the event recorder, or display
target messages. Moreover, they will not trigger the ANY MINOR ALARM or ANY SELF-TEST messages. When in the “Enabled”
mode, minor alarms continue to function along with other major and minor alarms. Refer to the Relay self-tests section in
chapter 7 for additional information on major and minor self-test alarms.
To enable the Ethernet switch failure function, ensure that the ETHERNET SWITCH FAIL FUNCTION is “Enabled” in this

NOTE
There are three standard control pushbuttons, labeled USER 1, USER 2, and USER 3, on the standard and enhanced front
panels. These are user-programmable and can be used for various applications such as performing an LED test, switching
setting groups, and invoking and scrolling though user-programmable displays.

The optional user-programmable pushbuttons (specified in the order code) provide an easy and error-free method of enter-
ing digital state (on, off) information. The number of available pushbuttons is dependent on the faceplate module ordered
with the relay.
• Type P faceplate: standard horizontal faceplate with 12 user-programmable pushbuttons.
• Type Q faceplate: enhanced horizontal faceplate with 16 user-programmable pushbuttons.
The digital state can be entered locally (by directly pressing the front panel pushbutton) or remotely (via FlexLogic™ oper-
ands) into FlexLogic™ equations, protection elements, and control elements. Typical applications include breaker control,
autorecloser blocking, and setting groups changes. The user-programmable pushbuttons are under the control level of
password protection.
The user-configurable pushbuttons for the enhanced faceplate are shown below.

The pushbuttons can be automatically controlled by activating the operands assigned to the PUSHBTN 1 SET (for latched and
self-reset mode) and PUSHBTN 1 RESET (for latched mode only) settings. The pushbutton reset status is declared when the
PUSHBUTTON 1 OFF operand is asserted. The activation and deactivation of user-programmable pushbuttons is dependent
on whether latched or self-reset mode is programmed.
• Latched mode: In latched mode, a pushbutton can be set (activated) by asserting the operand assigned to the PUSH-
BTN 1 SET setting or by directly pressing the associated front panel pushbutton. The pushbutton maintains the set state
until deactivated by the reset command or after a user-specified time delay. The state of each pushbutton is stored in
non-volatile memory and maintained through a loss of control power.
The pushbutton is reset (deactivated) in latched mode by asserting the operand assigned to the PUSHBTN 1 RESET set-
ting or by directly pressing the associated active front panel pushbutton.
It can also be programmed to reset automatically through the PUSHBTN 1 AUTORST and PUSHBTN 1 AUTORST DELAY set-
tings. These settings enable the autoreset timer and specify the associated time delay. The autoreset timer can be
used in select-before-operate (SBO) breaker control applications, where the command type (close/open) or breaker
location (feeder number) must be selected prior to command execution. The selection must reset automatically if con-
trol is not executed within a specified time period.
• Self-reset mode: In self-reset mode, a pushbutton will remain active for the time it is pressed (the pulse duration) plus
the dropout time specified in the PUSHBTN 1 DROP-OUT TIME setting. If the pushbutton is activated via FlexLogic™, the
pulse duration is specified by the PUSHBTN 1 DROP-OUT TIME only. The time the operand remains assigned to the PUSH-
BTN 1 SET setting has no effect on the pulse duration.
The pushbutton is reset (deactivated) in self-reset mode when the dropout delay specified in the PUSHBTN 1 DROP-OUT
TIMEsetting expires.
The pulse duration of the remote set, remote reset, or local pushbutton must be at least 50 ms to operate the push-
button. This allows the user-programmable pushbuttons to properly operate during power cycling events and vari-
NOTE ous system disturbances that may cause transient assertion of the operating signals.
The local and remote operation of each user-programmable pushbutton can be inhibited through the PUSHBTN 1 LOCAL and
PUSHBTN 1 REMOTE settings, respectively. If local locking is applied, the pushbutton will ignore set and reset commands
executed through the front panel pushbuttons. If remote locking is applied, the pushbutton will ignore set and reset com-
mands executed through FlexLogic™ operands.
The locking functions are not applied to the autorestart feature. In this case, the inhibit function can be used in SBO control
operations to prevent the pushbutton function from being activated and ensuring “one-at-a-time” select operation.
The locking functions can also be used to prevent the accidental pressing of the front panel pushbuttons. The separate
inhibit of the local and remote operation simplifies the implementation of local/remote control supervision.
5 Pushbutton states can be logged by the event recorder and displayed as target messages. In latched mode, user-defined
messages can also be associated with each pushbutton and displayed when the pushbutton is on or changing to off.
• PUSHBUTTON 1 FUNCTION: This setting selects the characteristic of the pushbutton. If set to “Disabled”, the push-
button is not active and the corresponding FlexLogic™ operands (both “On” and “Off”) are de-asserted. If set to “Self-
Reset”, the control logic is activated by the pulse (longer than 100 ms) issued when the pushbutton is being physically
pressed or virtually pressed via a FlexLogic™ operand assigned to the PUSHBTN 1 SET setting.
When in “Self-Reset” mode and activated locally, the pushbutton control logic asserts the “On” corresponding Flex-
Logic™ operand as long as the pushbutton is being physically pressed, and after being released the deactivation of
the operand is delayed by the drop out timer. The “Off” operand is asserted when the pushbutton element is deacti-
vated. If the pushbutton is activated remotely, the control logic of the pushbutton asserts the corresponding “On” Flex-
Logic™ operand only for the time period specified by the PUSHBTN 1 DROP-OUT TIME setting.
If set to “Latched”, the control logic alternates the state of the corresponding FlexLogic™ operand between “On” and
“Off” on each button press or by virtually activating the pushbutton (assigning set and reset operands). When in the
“Latched” mode, the states of the FlexLogic™ operands are stored in a non-volatile memory. Should the power supply
be lost, the correct state of the pushbutton is retained upon subsequent power up of the relay.
• PUSHBTN 1 ID TEXT: This setting specifies the top 20-character line of the user-programmable message and is
intended to provide ID information of the pushbutton. Refer to the User-definable displays section for instructions on
how to enter alphanumeric characters from the keypad.
• PUSHBTN 1 ON TEXT: This setting specifies the bottom 20-character line of the user-programmable message and is
displayed when the pushbutton is in the “on” position. Refer to the User-definable displays section for instructions on
entering alphanumeric characters from the keypad.
• PUSHBTN 1 OFF TEXT: This setting specifies the bottom 20-character line of the user-programmable message and is
displayed when the pushbutton is activated from the on to the off position and the PUSHBUTTON 1 FUNCTION is
“Latched”. This message is not displayed when the PUSHBUTTON 1 FUNCTION is “Self-reset” as the pushbutton operand
status is implied to be “Off” upon its release. The length of the “Off” message is configured with the PRODUCT SETUP
DISPLAY PROPERTIES FLASH MESSAGE TIME setting.
• PUSHBTN 1 HOLD: This setting specifies the time required for a pushbutton to be pressed before it is deemed active.
This timer is reset upon release of the pushbutton. Note that any pushbutton operation will require the pushbutton to be
pressed a minimum of 50 ms. This minimum time is required prior to activating the pushbutton hold timer.
• PUSHBTN 1 SET: This setting assigns the FlexLogic™ operand serving to operate the pushbutton element and to
assert PUSHBUTTON 1 ON operand. The duration of the incoming set signal must be at least 100 ms.
• PUSHBTN 1 RESET: This setting assigns the FlexLogic™ operand serving to reset pushbutton element and to assert
PUSHBUTTON 1 OFF operand. This setting is applicable only if pushbutton is in latched mode. The duration of the
incoming reset signal must be at least 50 ms.
• PUSHBTN 1 AUTORST: This setting enables the user-programmable pushbutton autoreset feature. This setting is
applicable only if the pushbutton is in the “Latched” mode.
• PUSHBTN 1 AUTORST DELAY: This setting specifies the time delay for automatic reset of the pushbutton when in
the latched mode.
• PUSHBTN 1 REMOTE: This setting assigns the FlexLogic™ operand serving to inhibit pushbutton operation from the
operand assigned to the PUSHBTN 1 SET or PUSHBTN 1 RESET settings.
• PUSHBTN 1 LOCAL: This setting assigns the FlexLogic™ operand serving to inhibit pushbutton operation from the
front panel pushbuttons. This locking functionality is not applicable to pushbutton autoreset.
• PUSHBTN 1 DROP-OUT TIME: This setting applies only to “Self-Reset” mode and specifies the duration of the push-
button active status after the pushbutton has been released. When activated remotely, this setting specifies the entire
activation time of the pushbutton status; the length of time the operand remains on has no effect on the pulse duration.
This setting is required to set the duration of the pushbutton operating pulse.
• PUSHBTN 1 LED CTL: This setting assigns the FlexLogic™ operand serving to drive pushbutton LED. If this setting is
“Off”, then LED operation is directly linked to PUSHBUTTON 1 ON operand.
• PUSHBTN 1 MESSAGE: If pushbutton message is set to “High Priority”, the message programmed in the PUSHBTN 1
IDand PUSHBTN 1 ON TEXT settings will be displayed undisturbed as long as PUSHBUTTON 1 ON operand is asserted.
The high priority option is not applicable to the PUSHBTN 1 OFF TEXT setting.
This message can be temporary removed if any front panel keypad button is pressed. However, ten seconds of keypad 5
inactivity will restore the message if the PUSHBUTTON 1 ON operand is still active.
If the PUSHBTN 1 MESSAGE is set to “Normal”, the message programmed in the PUSHBTN 1 ID and PUSHBTN 1 ON TEXT
settings will be displayed as long as PUSHBUTTON 1 ON operand is asserted, but not longer than time period specified
by FLASH MESSAGE TIME setting. After the flash time is expired, the default message or other active target message is
displayed. The instantaneous reset of the flash message will be executed if any relay front panel button is pressed or
any new target or message becomes active.
The PUSHBTN 1 OFF TEXT setting is linked to PUSHBUTTON 1 OFF operand and will be displayed in conjunction with
PUSHBTN 1 ID only if pushbutton element is in the “Latched” mode. The PUSHBTN 1 OFF TEXT message will be displayed
as “Normal” if the PUSHBTN 1 MESSAGE setting is “High Priority” or “Normal”.
• PUSHBUTTON 1 EVENTS: If this setting is enabled, each pushbutton state change will be logged as an event into
event recorder.

This feature provides a mechanism where any of 256 selected FlexLogic™ operand states can be used for efficient moni-
toring. The feature allows user-customized access to the FlexLogic™ operand states in the relay. The state bits are packed
so that 16 states may be read out in a single Modbus register. The state bits can be configured so that all of the states
which are of interest to the user are available in a minimum number of Modbus registers.
The state bits may be read out in the “Flex States” register array beginning at Modbus address 0900h. Sixteen states are
packed into each register, with the lowest-numbered state in the lowest-order bit. There are sixteen registers to accommo-
date the 256 state bits.

PATH: SETTINGS PRODUCT SETUP USER-DEFINABLE DISPLAYS
5 MESSAGE
USER DISPLAY 16
Range: up to 20 alphanumeric characters
This menu provides a mechanism for manually creating up to 16 user-defined information displays in a convenient viewing
sequence in the USER DISPLAYS menu (between the TARGETS and ACTUAL VALUES top-level menus). The sub-menus facili-
tate text entry and Modbus register data pointer options for defining the user display content.
Once programmed, the user-definable displays can be viewed in two ways.
• KEYPAD: Use the MENU key to select the USER DISPLAYS menu item to access the first user-definable display (note
that only the programmed screens are displayed). The screens can be scrolled using the UP and DOWN keys. The
display disappears after the default message time-out period specified by the PRODUCT SETUP DISPLAY PROPER-
TIES DEFAULT MESSAGE TIMEOUT setting.
• USER-PROGRAMMABLE CONTROL INPUT: The user-definable displays also respond to the INVOKE AND SCROLL
setting. Any FlexLogic™ operand (in particular, the user-programmable pushbutton operands), can be used to navi-
gate the programmed displays.
On the rising edge of the configured operand (such as when the pushbutton is pressed), the displays are invoked by
showing the last user-definable display shown during the previous activity. From this moment onward, the operand
acts exactly as the down key and allows scrolling through the configured displays. The last display wraps up to the first
one. The INVOKE AND SCROLL input and the DOWN key operate concurrently.
When the default timer expires (set by the DEFAULT MESSAGE TIMEOUT setting), the relay will start to cycle through the
user displays. The next activity of the INVOKE AND SCROLL input stops the cycling at the currently displayed user dis-
play, not at the first user-defined display. The INVOKE AND SCROLL pulses must last for at least 250 ms to take effect.
Any existing system display can be automatically copied into an available user display by selecting the existing display and
pressing the ENTER key. The display will then prompt ADD TO USER DISPLAY LIST?. After selecting “Yes”, a message indi-
cates that the selected display has been added to the user display list. When this type of entry occurs, the sub-menus are
automatically configured with the proper content – this content may subsequently be edited.
This menu is used to enter user-defined text and user-selected Modbus-registered data fields into the particular user dis- 5
play. Each user display consists of two 20-character lines (top and bottom). The tilde (~) character is used to mark the start
of a data field – the length of the data field needs to be accounted for. Up to five separate data fields can be entered in a
user display – the nth tilde (~) refers to the nth item.
A user display may be entered from the faceplate keypad or the EnerVista UR Setup interface (preferred for convenience).
The following procedure shows how to enter text characters in the top and bottom lines from the faceplate keypad:
1. Select the line to be edited.
2. Press the decimal key to enter text edit mode.
3. Use either VALUE key to scroll through the characters. A space is selected like a character.
4. Press the decimal key to advance the cursor to the next position.
5. Repeat step 3 and continue entering characters until the desired text is displayed.
6. The HELP key may be pressed at any time for context sensitive help information.
7. Press the ENTER key to store the new settings.
To enter a numerical value for any of the five items (the decimal form of the selected Modbus address) from the faceplate
keypad, use the number keypad. Use the value of “0” for any items not being used. Use the HELP key at any selected sys-
tem display (setting, actual value, or command) which has a Modbus address, to view the hexadecimal form of the Modbus
address, then manually convert it to decimal form before entering it (EnerVista UR Setup usage conveniently facilitates this
conversion).
Use the MENU key to go to the user displays menu to view the user-defined content. The current user displays will show in
sequence, changing every four seconds. While viewing a user display, press the ENTER key and then select the ‘Yes”
option to remove the display from the user display list. Use the MENU key again to exit the user displays menu.

a) MAIN MENU
PATH: SETTINGS PRODUCT SETUP DIRECT I/O
Direct inputs and outputs are intended for exchange of status information (inputs and outputs) between UR-series relays
connected directly via type 7 digital communications cards. The mechanism is very similar to IEC 61850 GSSE, except that
communications takes place over a non-switchable isolated network and is optimized for speed. On type 7 cards that sup-
port two channels, direct output messages are sent from both channels simultaneously. This effectively sends direct output
messages both ways around a ring configuration. On type 7 cards that support one channel, direct output messages are
sent only in one direction. Messages will be resent (forwarded) when it is determined that the message did not originate at
the receiver.
Direct output message timing is similar to GSSE message timing. Integrity messages (with no state changes) are sent at
least every 1000 ms. Messages with state changes are sent within the main pass scanning the inputs and asserting the
outputs unless the communication channel bandwidth has been exceeded. Two self-tests are performed and signaled by
the following FlexLogic™ operands:
1. DIRECT RING BREAK (direct input/output ring break). This FlexLogic™ operand indicates that direct output messages
sent from a UR-series relay are not being received back by the relay.
2. DIRECT DEVICE 1 OFF to DIRECT DEVICE 16 OFF (direct device offline). These FlexLogic™ operands indicate that direct
output messages from at least one direct device are not being received.
Direct input and output settings are similar to remote input and output settings. The equivalent of the remote device name
strings for direct inputs and outputs is the DIRECT OUTPUT DEVICE ID. The DIRECT OUTPUT DEVICE ID setting identifies the
relay in all direct output messages. All UR-series IEDs in a ring should have unique numbers assigned. The IED ID is used
to identify the sender of the direct input and output message.
If the direct input and output scheme is configured to operate in a ring (DIRECT I/O CH1 RING CONFIGURATION or DIRECT I/O
CH2 RING CONFIGURATION is “Yes”), all direct output messages should be received back. If not, the direct input/output ring
break self-test is triggered. The self-test error is signaled by the DIRECT RING BREAK FlexLogic™ operand.
Select the DIRECT I/O DATA RATE to match the data capabilities of the communications channel. All IEDs communicating
over direct inputs and outputs must be set to the same data rate. UR-series IEDs equipped with dual-channel communica- 5
tions cards apply the same data rate to both channels. Delivery time for direct input and output messages is approximately
0.2 of a power system cycle at 128 kbps and 0.4 of a power system cycle at 64 kbps, per each ‘bridge’.
The G.703 modules are fixed at 64 kbps. The DIRECT I/O DATA RATE setting is not applicable to these modules.
NOTE
The DIRECT I/O CHANNEL CROSSOVER setting applies to T60s with dual-channel communication cards and allows crossing
over messages from channel 1 to channel 2. This places all UR-series IEDs into one direct input and output network
regardless of the physical media of the two communication channels.
The following application examples illustrate the basic concepts for direct input and output configuration. Please refer to the
Inputs and outputs section in this chapter for information on configuring FlexLogic™ operands (flags, bits) to be exchanged.

The T60 checks integrity of the incoming direct input and output messages using a 32-bit CRC. The CRC alarm function is
available for monitoring the communication medium noise by tracking the rate of messages failing the CRC check. The
monitoring function counts all incoming messages, including messages that failed the CRC check. A separate counter adds
up messages that failed the CRC check. When the failed CRC counter reaches the user-defined level specified by the CRC
ALARM CH1 THRESHOLD setting within the user-defined message count CRC ALARM 1 CH1 COUNT, the DIR IO CH1 CRC ALARM
FlexLogic™ operand is set.
When the total message counter reaches the user-defined maximum specified by the CRC ALARM CH1 MESSAGE COUNT set-
ting, both the counters reset and the monitoring process is restarted.
The operand shall be configured to drive an output contact, user-programmable LED, or selected communication-based
output. Latching and acknowledging conditions - if required - should be programmed accordingly.
The CRC alarm function is available on a per-channel basis. The total number of direct input and output messages that
failed the CRC check is available as the ACTUAL VALUES STATUS DIRECT INPUTS CRC FAIL COUNT CH1 actual
value.
• Message count and length of the monitoring window: To monitor communications integrity, the relay sends 1 message
per second (at 64 kbps) or 2 messages per second (128 kbps) even if there is no change in the direct outputs. For
example, setting the CRC ALARM CH1 MESSAGE COUNT to “10000”, corresponds a time window of about 160 minutes at
64 kbps and 80 minutes at 128 kbps. If the messages are sent faster as a result of direct outputs activity, the monitor-
ing time interval will shorten. This should be taken into account when determining the CRC ALARM CH1 MESSAGE COUNT
setting. For example, if the requirement is a maximum monitoring time interval of 10 minutes at 64 kbps, then the CRC
ALARM CH1 MESSAGE COUNT should be set to 10 60 1 = 600.
• Correlation of failed CRC and bit error rate (BER): The CRC check may fail if one or more bits in a packet are cor-
rupted. Therefore, an exact correlation between the CRC fail rate and the BER is not possible. Under certain assump-
tions an approximation can be made as follows. A direct input and output packet containing 20 bytes results in 160 bits
of data being sent and therefore, a transmission of 63 packets is equivalent to 10,000 bits. A BER of 10–4 implies 1 bit
error for every 10000 bits sent or received. Assuming the best case of only 1 bit error in a failed packet, having 1 failed
packet for every 63 received is about equal to a BER of 10–4.

The T60 checks integrity of the direct input and output communication ring by counting unreturned messages. In the ring
configuration, all messages originating at a given device should return within a pre-defined period of time. The unreturned
messages alarm function is available for monitoring the integrity of the communication ring by tracking the rate of unre-
turned messages. This function counts all the outgoing messages and a separate counter adds the messages have failed

5.2.18 TELEPROTECTION
Digital teleprotection functionality is designed to transfer protection commands between two or three relays in a secure,
fast, dependable, and deterministic fashion. Possible applications are permissive or blocking pilot schemes and direct
transfer trip (DTT). Teleprotection can be applied over any analog or digital channels and any communications media, such
as direct fiber, copper wires, optical networks, or microwave radio links. A mixture of communication media is possible.
Once teleprotection is enabled and the teleprotection input/outputs are configured, data packets are transmitted continu-
5 ously every 1/4 cycle (3/8 cycle if using C37.94 modules) from peer-to-peer. Security of communication channel data is
achieved by using CRC-32 on the data packet.
Teleprotection inputs/outputs and direct inputs/outputs are mutually exclusive – as such, they cannot be used simu-
latneously. Once teleprotection inputs and outputs are enabled, direct inputs and outputs are blocked, and vice
NOTE versa.
• NUMBER OF TERMINALS: Specifies whether the teleprotection system operates between two peers or three peers.
• NUMBER OF CHANNELS: Specifies how many channels are used. If the NUMBER OF TERMINALS is “3” (three-terminal
system), set the NUMBER OF CHANNELS to “2”. For a two-terminal system, the NUMBER OF CHANNELS can set to “1” or
“2” (redundant channels).
• LOCAL RELAY ID NUMBER, TERMINAL 1 RELAY ID NUMBER, and TERMINAL 2 RELAY ID NUMBER: In installa-
tions that use multiplexers or modems, it is desirable to ensure that the data used by the relays protecting a given line
is from the correct relays. The teleprotection function performs this check by reading the message ID sent by transmit-
ting relays and comparing it to the programmed ID in the receiving relay. This check is also used to block inputs if inad-
vertently set to loopback mode or data is being received from a wrong relay by checking the ID on a received channel.
If an incorrect ID is found on a channel during normal operation, the TELEPROT CH1 ID FAIL or TELEPROT CH2 ID FAIL
FlexLogic™ operand is set, driving the event with the same name and blocking the teleprotection inputs. For commis-
sioning purposes, the result of channel identification is also shown in the STATUS CHANNEL TESTS VALIDITY OF
CHANNEL CONFIGURATION actual value. The default value of “0” for the LOCAL RELAY ID NUMBER indicates that relay ID
is not to be checked. On two- terminals two-channel systems, the same LOCAL RELAY ID NUMBER is transmitted over
both channels; as such, only the TERMINAL 1 ID NUMBER has to be programmed on the receiving end.
5.2.19 INSTALLATION
To safeguard against the installation of a relay without any entered settings, the unit will not allow signaling of any output
relay until RELAY SETTINGS is set to "Programmed". This setting is defaulted to "Not Programmed" when at the factory. The
UNIT NOT PROGRAMMED self-test error message is displayed until the relay is put into the "Programmed" state.
The RELAY NAME setting allows the user to uniquely identify a relay. This name will appear on generated reports. This name
is also used to identify specific devices which are engaged in automatically sending/receiving data over the Ethernet com-
munications channel using the IEC 61850 protocol.
When T60 is ordered with a process card module as a part of HardFiber system, then an additional Remote Resources
menu tree is available in EnerVista UR Setup software to allow configuring HardFiber system.
a) CURRENT BANKS
PATH: SETTINGS SYSTEM SETUP AC INPUTS CURRENT BANK F1(U5)
Because energy parameters are accumulated, these values should be recorded and then reset immediately
prior to changing CT characteristics.
NOTE
Six banks of phase and ground CTs can be set, where the current banks are denoted in the following format (X represents
the module slot position letter):
Xa, where X = {F, M, U} and a = {1, 5}.
See the Introduction to AC Sources section at the beginning of this chapter for additional details.
These settings are critical for all features that have settings dependent on current measurements. When the relay is
ordered, the CT module must be specified to include a standard or sensitive ground input. As the phase CTs are connected
in wye (star), the calculated phasor sum of the three phase currents (IA + IB + IC = neutral current = 3Io) is used as the
5
input for the neutral overcurrent elements. In addition, a zero-sequence (core balance) CT which senses current in all of the
circuit primary conductors, or a CT in a neutral grounding conductor may also be used. For this configuration, the ground
CT primary rating must be entered. To detect low level ground fault currents, the sensitive ground input may be used. In this
case, the sensitive ground CT primary rating must be entered. Refer to chapter 3 for more details on CT connections.
Enter the rated CT primary current values. For both 1000:5 and 1000:1 CTs, the entry would be 1000. For correct opera-
tion, the CT secondary rating must match the setting (which must also correspond to the specific CT connections used).
The following example illustrates how multiple CT inputs (current banks) are summed as one source current. Given If the
following current banks:
• F1: CT bank with 500:1 ratio.
• F5: CT bank with 1000: ratio.
• M1: CT bank with 800:1 ratio.
The following rule applies:
SRC 1 = F1 + F5 + M1 (EQ 5.7)
1 pu is the highest primary current. In this case, 1000 is entered and the secondary current from the 500:1 ratio CT will be
adjusted to that created by a 1000:1 CT before summation. If a protection element is set up to act on SRC 1 currents, then
a pickup level of 1 pu will operate on 1000 A primary.
The same rule applies for current sums from CTs with different secondary taps (5 A and 1 A).
b) VOLTAGE BANKS
PATH: SETTINGS SYSTEM SETUP AC INPUTS VOLTAGE BANK F5(U5)
Because energy parameters are accumulated, these values should be recorded and then reset immediately
prior to changing VT characteristics.
CAUTION
Three banks of phase/auxiliary VTs can be set, where voltage banks are denoted in the following format (X represents the
module slot position letter):
Xa, where X = {F, M, U} and a = {5}.
5 See the Introduction to AC sources section at the beginning of this chapter for additional details.
With VTs installed, the relay can perform voltage measurements as well as power calculations. Enter the PHASE VT F5 CON-
NECTION made to the system as “Wye” or “Delta”. An open-delta source VT connection would be entered as “Delta”.
The nominal PHASE VT F5 SECONDARY voltage setting is the voltage across the relay input terminals when nominal
voltage is applied to the VT primary.
NOTE
For example, on a system with a 13.8 kV nominal primary voltage and with a 14400:120 volt VT in a delta connec-
tion, the secondary voltage would be 115; that is, (13800 / 14400) × 120. For a wye connection, the voltage value
entered must be the phase to neutral voltage which would be 115 3 = 66.4.
On a 14.4 kV system with a delta connection and a VT primary to secondary turns ratio of 14400:120, the voltage
value entered would be 120; that is, 14400 / 120.
The power system NOMINAL FREQUENCY value is used as a default to set the digital sampling rate if the system frequency
cannot be measured from available signals. This may happen if the signals are not present or are heavily distorted. Before
reverting to the nominal frequency, the frequency tracking algorithm holds the last valid frequency measurement for a safe
period of time while waiting for the signals to reappear or for the distortions to decay.
The phase sequence of the power system is required to properly calculate sequence components and power parameters.
The PHASE ROTATION setting matches the power system phase sequence. Note that this setting informs the relay of the
actual system phase sequence, either ABC or ACB. CT and VT inputs on the relay, labeled as A, B, and C, must be con-
nected to system phases A, B, and C for correct operation.
The FREQUENCY AND PHASE REFERENCE setting determines which signal source is used (and hence which AC signal) for
phase angle reference. The AC signal used is prioritized based on the AC inputs that are configured for the signal source:
phase voltages takes precedence, followed by auxiliary voltage, then phase currents, and finally ground current. 5
For three phase selection, phase A is used for angle referencing ( V ANGLE REF = V A ), while Clarke transformation of the
phase signals is used for frequency metering and tracking ( V FREQUENCY = 2V A – V B – V C 3 ) for better performance dur-
ing fault, open pole, and VT and CT fail conditions.
The phase reference and frequency tracking AC signals are selected based upon the Source configuration, regardless of
whether or not a particular signal is actually applied to the relay.
Phase angle of the reference signal will always display zero degrees and all other phase angles will be relative to this sig-
nal. If the pre-selected reference signal is not measurable at a given time, the phase angles are not referenced.
The phase angle referencing is done via a phase locked loop, which can synchronize independent UR-series relays if they
have the same AC signal reference. These results in very precise correlation of time tagging in the event recorder between
different UR-series relays provided the relays have an IRIG-B connection.
FREQUENCY TRACKING should only be set to “Disabled” in very unusual circumstances; consult the factory for spe-
cial variable-frequency applications.
NOTE
The frequency tracking feature will function only when the T60 is in the “Programmed” mode. If the T60 is “Not Pro-
grammed”, then metering values will be available but may exhibit significant errors.
NOTE
Systems with an ACB phase sequence require special consideration. Refer to the Phase relationships of
three-phase transformers sub-section of chapter 5.
NOTE
Identical menus are available for each source. The "SRC 1" text can be replaced by with a user-defined name appropriate
for the associated source.
The first letter in the source identifier represents the module slot position. The number directly following this letter repre-
sents either the first bank of four channels (1, 2, 3, 4) called “1” or the second bank of four channels (5, 6, 7, 8) called “5” in
a particular CT/VT module. Refer to the Introduction to AC sources section at the beginning of this chapter for additional
details on this concept.
It is possible to select the sum of all CT combinations. The first channel displayed is the CT to which all others will be
5 referred. For example, the selection “F1+F5” indicates the sum of each phase from channels “F1” and “F5”, scaled to
whichever CT has the higher ratio. Selecting “None” hides the associated actual values.
The approach used to configure the AC sources consists of several steps; first step is to specify the information about each
CT and VT input. For CT inputs, this is the nominal primary and secondary current. For VTs, this is the connection type,
ratio and nominal secondary voltage. Once the inputs have been specified, the configuration for each source is entered,
including specifying which CTs will be summed together.
User selection of AC parameters for comparator elements:
CT/VT modules automatically calculate all current and voltage parameters from the available inputs. Users must select the
specific input parameters to be measured by every element in the relevant settings menu. The internal design of the ele-
ment specifies which type of parameter to use and provides a setting for source selection. In elements where the parameter
may be either fundamental or RMS magnitude, such as phase time overcurrent, two settings are provided. One setting
specifies the source, the second setting selects between fundamental phasor and RMS.
AC input actual values:
The calculated parameters associated with the configured voltage and current inputs are displayed in the current and volt-
age sections of actual values. Only the phasor quantities associated with the actual AC physical input channels will be dis-
played here. All parameters contained within a configured source are displayed in the sources section of the actual values.
DISTURBANCE DETECTORS (INTERNAL):
The disturbance detector (ANSI 50DD) element is a sensitive current disturbance detector that detects any disturbance on
the protected system. The 50DD function is intended for use in conjunction with measuring elements, blocking of current
based elements (to prevent maloperation as a result of the wrong settings), and starting oscillography data capture. A dis-
turbance detector is provided for each source.
The 50DD function responds to the changes in magnitude of the sequence currents. The disturbance detector scheme
logic is as follows:

tem. The following figure shows the arrangement of sources used to provide the functions required in this application, and

The T60 Transformer Protection System has been designed to provide primary protection for medium to high voltage power
transformers. It is able to perform this function on 2 to 5 winding transformers in a variety of system configurations.
5 b) GENERAL TRANSFORMER SETTINGS
PATH: SETTINGS SYSTEM SETUP TRANSFORMER GENERAL
The general transformer settings apply to all windings. Settings specific to each winding are shown in the following section.
• NUMBER OF WINDINGS: Selects the number of windings for transformer setup.
• PHASE COMPENSATION: Selects the type of phase compensation to be performed by the relay. If set to “Internal
(software)”, the transformer phase shift is compensated internally by the relay algorithm. If set to “External (with CTs)”,
the transformer phase shift is externally compensated by the CT connections.
• LOAD LOSS AT RATED LOAD: This setting should be taken from the transformer nameplate. If not available from the
2
nameplate, the setting value can be computed as P R = I n W R , where I n W is the winding rated current and R is
the three-phase series resistance. The setting is used as an input for the calculation of the hottest-spot winding tem-
perature.
• RATED WINDING TEMP RISE: This setting defines the winding temperature rise over 30°C ambient temperature. The
setting is automatically selected for the transformer type as shown in the table below.
The loss of life function calculates the insulation aging acceleration factor using the settings entered in this section, by
following equation:
15000
---------------------------- 15000 -
- – ---------------------------
H_R + 273 H t + 273
F AA t = e (EQ 5.8)
where H_R is the rated hottest-spot temperature as per the table below,
and H t is the actual computed winding hottest-spot temperature.
The aging acceleration factor is computed every minute. It has a value of 1.0 when the actual winding hottest spot tem-
perature is equal to the rated temperature, is greater than 1 if the actual temperature is above the rated temperature,
and less than 1 if the actual temperature is below the rated temperature.
• NO LOAD LOSS: This setting is obtained from the transformer data and is used to calculate the aging acceleration
factor.
• TYPE OF COOLING: The setting defines the type of transformer cooling and is used to calculate the aging accelera-
tion factor. The values and their description for this setting are as follows:
“OA”: oil-air
“FA”: forced air
“Non-directed FOA/FOW”: non-directed forced-oil-air/forced-oil-water
“Directed FOA/FOW”: directed forced-oil-air/forced-oil-water
“Sealed Self Cooled”, “Vented Self Cooled”, “Forced Cooled”: as named
• TOP OIL RISE OVER AMBIENT: This setting should be available from the transformer nameplate data
• THERMAL CAPACITY: The setting should be available from the transformer nameplate data. If not, refer to the follow-
ing calculations. For the “OA” and “FA” cooling types:
C = 0.06 (core and coil assembly in lbs.) + 0.04 (tank and fittings in lbs.) +1.33 (gallons of oil), Wh/°C; or
C = 0.0272 (core and coil assembly in kg) + 0.01814 (tank and fittings in kg) + 5.034 (L of oil), Wh/°C
For the “Non-directed FOA/FOW” (non-directed forced-oil-air/forced-oil-water) or “Directed FOA/FOW” (directed
forced-oil-air/forced-oil-water) cooling types, the thermal capacity is given by:
C = 0.06 (core and coil assembly in lbs.) + 0.06 (tank and fittings in lbs.) + 1.93 (gallons of oil), Wh/°C; or
C =0.0272 (weight of core and coil assembly in kg) + 0.0272 (weight of tank and fittings in kg) + 7.305 (L of oil), Wh/°C

It may be suggested that phase relationship for the ACB sequence can be returned the transformer nameplate values by
connecting source phases A, B and C to transformer terminals A, C, and B respectively. Although this restores the name-
plate phase shifts, it causes incorrect identification of phases B and C within the relay, and is therefore not recommended.
All information presented in this manual is based on connecting the relay phase A, B and C terminals to the power system
phases A, B, and C respectively. The transformer types and phase relationships presented are for a system phase
sequence of ABC, in accordance with the standards for power transformers. Users with a system phase sequence of ACB
must determine the transformer type for this sequence.
If a power system with ACB rotation is connected to the Wye winding terminals 1, 2, and 3, respectively, from a Y/d30 trans-
former, select a Power Rotation setting of ACB into the relay and enter data for the Y/d330 transformer type.
e) MAGNITUDE COMPENSATION
Transformer protection presents problems in the application of current transformers. CTs should be matched to the current
rating of each transformer winding, so that normal current through the power transformer is equal on the secondary side of
the CT on different windings. However, because only standard CT ratios are available, this matching may not be exact.
In our example, the transformer has a voltage ratio of 220 kV / 69 kV (i.e. about 3.188 to 1) and a compensating CT ratio is
500 A to 1500 A (i.e. 1 to 3). Historically, this would have resulted in a steady state current at the differential relay. Interpos-
ing CTs or tapped relay windings were used to minimize this error.
The T60 automatically corrects for CT mismatch errors. All currents are magnitude compensated to be in units of the CTs of
one winding before the calculation of differential and restraint quantities.
The reference winding (wref) is the winding to which all currents are referred. This means that the differential and restraint
currents will be in per unit of nominal of the CTs on the reference winding. This is important to know, because the settings of
the operate characteristic of the percent differential element (pickup, breakpoints 1 and 2) are entered in terms of the same
per unit of nominal.
The reference winding is chosen by the relay to be the winding which has the smallest margin of CT primary current with 5
respect to winding rated current, meaning that the CTs on the reference winding will most likely begin to saturate before
those on other windings with heavy through currents. The characteristics of the reference winding CTs determine how the
percent differential element operate characteristic should be set.
The T60 determines the reference winding as follows:
1. Calculate the rated current (Irated) for each winding:
P rated w
- , where w = 1 2 w total
I rated w = ------------------------------------ (EQ 5.9)
3 V nom w
Note: enter the self-cooled MVA rating for the Prated setting.
2. Calculate the CT margin (Imargin) for each winding:
CT primary w
I margin = --------------------------------------- , where w = 1 2 w total (EQ 5.10)
I rated w
2. With these rated currents, calculate the CT margin for windings 1 and 2:
primary 1 - = -------------------- CT primary 2
I margin 1 = CT
500 A - = 1.91 1500 A
------------------------------------- , I margin 2 = -------------------------------------- = --------------------- = 1.79 (EQ 5.12)
I rated 1 262.4 A I rated 2 836.7 A
The unit for calculation of the differential and restraint currents and base for the differential restraint settings is the CT pri-
mary associated with the reference winding. In this example, the unit CT is 1500:5 on winding 2.
Magnitude compensation factors (M) are the scaling values by which each winding current is multiplied to refer it to the ref-
erence winding. The T60 calculates magnitude compensation factors for each winding as follows:
I primary w V nom w
M w = ---------------------------------------------------------------------- , where w = 1 2 w total (EQ 5.13)
I primary w ref V nom w ref
The maximum allowed magnitude compensation factor (and hence the maximum allowed CT ratio mismatch) is 32.

p 2 1 1 p 2 1 1 p 2 1 1
I A 1 = --- I A 1 – --- I B 1 – --- I C 1 ; I B 1 = --- I B 1 – --- I A 1 – --- I C 1 ; I C 1 = --- I C 1 – --- I A 1 – --- I B 1 (EQ 5.16)
3 3 3 3 3 3 3 3 3
For Winding 2:
p 1 1 p 1 1 p 1 1
I A w = ------- I A 2 – ------- I B 2 ; I B w = ------- I B 2 – ------- I C 2 ; I C w = ------- I C 2 – ------- I A 2 (EQ 5.17)
3 3 3 3 3 3
c p
I B w = M w I B w , where w = 1 2 w total (EQ 5.19)
c p
I C w = M w I C w , where w = 1 2 w total (EQ 5.20)
c c c
where: IA w , IB w , and IC w
= magnitude, phase and zero sequence compensated winding w phase currents
M w = magnitude compensation factor for winding w (see previous sections)
p c c
I A w , I B w , and I C w = phase and zero sequence compensated winding w phase currents (see earlier)
c c c
Id B = I B 1 + I B 2 + + I B w total (EQ 5.22)
c c c
Id C = I C 1 + I C 2 + + I C w total (EQ 5.23)
c c c
Ir A = max I A 1 I A 2 I A w total (EQ 5.24)
c c c
Ir B = max I B 1 I B 2 I B w total (EQ 5.25)
c c c
Ir C = max I C 1 I C 2 I C w total (EQ 5.26)
where Id A , Id B , and Id C are the phase differential currents and Ir A , Ir B , and Ir C are the phase restraint currents.

A description of the operation of the breaker control and status monitoring features is provided in chapter 4. Only informa-
tion concerning programming of the associated settings is covered here. These features are provided for two or more
breakers; a user may use only those portions of the design relevant to a single breaker, which must be breaker 1.
The number of breaker control elements is dependent on the number of CT/VT modules specified with the T60. The follow-
ing settings are available for each breaker control element.
• BREAKER 1 FUNCTION: This setting enables and disables the operation of the breaker control feature.
• BREAKER1 PUSH BUTTON CONTROL: Set to “Enable” to allow faceplate push button operations.
• BREAKER 1 NAME: Assign a user-defined name (up to six characters) to the breaker. This name will be used in flash
messages related to breaker 1.
• BREAKER 1 MODE: This setting selects “3-Pole” mode, where all breaker poles are operated simultaneously, or “1-
Pole” mode where all breaker poles are operated either independently or simultaneously.
• BREAKER 1 OPEN: This setting selects an operand that creates a programmable signal to operate an output relay to
open breaker 1.
• BREAKER 1 BLK OPEN: This setting selects an operand that prevents opening of the breaker. This setting can be
used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
• BREAKER 1 CLOSE: This setting selects an operand that creates a programmable signal to operate an output relay
to close breaker 1.
• BREAKER 1 BLK CLOSE: This setting selects an operand that prevents closing of the breaker. This setting can be
used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
• BREAKER 1 A/3P CLOSED: This setting selects an operand, usually a contact input connected to a breaker auxil-
iary position tracking mechanism. This input should be a normally-open 52/a status input to create a logic 1 when the
breaker is closed. If the BREAKER 1 MODE setting is selected as “3-Pole”, this setting selects a single input as the oper-
and used to track the breaker open or closed position. If the mode is selected as “1-Pole”, the input mentioned above
5
is used to track phase A and the BREAKER 1 B and BREAKER 1 C settings select operands to track phases B and C,
respectively.
• BREAKER 1 A/3P OPND: This setting selects an operand, usually a contact input, that should be a normally-closed
52/b status input to create a logic 1 when the breaker is open. If a separate 52/b contact input is not available, then the
inverted BREAKER 1 CLOSED status signal can be used.
• BREAKER 1 B CLOSED: If the mode is selected as three-pole, this setting has no function. If the mode is selected
as single-pole, this input is used to track the breaker phase B closed position as above for phase A.
• BREAKER 1 B OPENED: If the mode is selected as three-pole, this setting has no function. If the mode is selected
as single-pole, this input is used to track the breaker phase B opened position as above for phase A.
• BREAKER 1 C CLOSED: If the mode is selected as three-pole, this setting has no function. If the mode is selected
as single-pole, this input is used to track the breaker phase C closed position as above for phase A.
• BREAKER 1 C OPENED: If the mode is selected as three-pole, this setting has no function. If the mode is selected
as single-pole, this input is used to track the breaker phase C opened position as above for phase A.
• BREAKER 1 Toperate: This setting specifies the required interval to overcome transient disagreement between the
52/a and 52/b auxiliary contacts during breaker operation. If transient disagreement still exists after this time has
expired, the BREAKER 1 BAD STATUS FlexLogic™ operand is asserted from alarm or blocking purposes.
• BREAKER 1 EXT ALARM: This setting selects an operand, usually an external contact input, connected to a breaker
alarm reporting contact.
• BREAKER 1 ALARM DELAY: This setting specifies the delay interval during which a disagreement of status among
the three-pole position tracking operands will not declare a pole disagreement. This allows for non-simultaneous oper-
ation of the poles.
• MANUAL CLOSE RECAL1 TIME: This setting specifies the interval required to maintain setting changes in effect after
an operator has initiated a manual close command to operate a circuit breaker.
• BREAKER 1 OUT OF SV: Selects an operand indicating that breaker 1 is out-of-service.

The disconnect switch element contains the auxiliary logic for status and serves as the interface for opening and closing of
disconnect switches from SCADA or through the front panel interface. The disconnect switch element can be used to cre-
ate an interlocking functionality. For greater security in determination of the switch pole position, both the 52/a and 52/b
auxiliary contacts are used with reporting of the discrepancy between them. The number of available disconnect switches
depends on the number of the CT/VT modules ordered with the T60.
• SWITCH 1 FUNCTION: This setting enables and disables the operation of the disconnect switch element.
• SWITCH 1 NAME: Assign a user-defined name (up to six characters) to the disconnect switch. This name will be used
in flash messages related to disconnect switch 1.
• SWITCH 1 MODE: This setting selects “3-Pole” mode, where all disconnect switch poles are operated simultaneously,
or “1-Pole” mode where all disconnect switch poles are operated either independently or simultaneously.
• SWITCH 1 OPEN: This setting selects an operand that creates a programmable signal to operate an output relay to
open disconnect switch 1.
• SWITCH 1 BLK OPEN: This setting selects an operand that prevents opening of the disconnect switch. This setting
can be used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
• SWITCH 1 CLOSE: This setting selects an operand that creates a programmable signal to operate an output relay to
close disconnect switch 1.
• SWITCH 1 BLK CLOSE: This setting selects an operand that prevents closing of the disconnect switch. This setting
can be used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
• SWTCH 1 A/3P CLSD: This setting selects an operand, usually a contact input connected to a disconnect switch
auxiliary position tracking mechanism. This input should be a normally-open 52/a status input to create a logic 1 when
the disconnect switch is closed. If the SWITCH 1 MODE setting is selected as “3-Pole”, this setting selects a single input
as the operand used to track the disconnect switch open or closed position. If the mode is selected as “1-Pole”, the
input mentioned above is used to track phase A and the SWITCH 1 B and SWITCH 1 C settings select operands to
track phases B and C, respectively.
• SWITCH 1 A/3P OPND: This setting selects an operand, usually a contact input, that should be a normally-closed
52/b status input to create a logic 1 when the disconnect switch is open. If a separate 52/b contact input is not avail-
able, then the inverted SWITCH 1 CLOSED status signal can be used.
• SWITCH 1 B CLOSED: If the mode is selected as three-pole, this setting has no function. If the mode is selected as
single-pole, this input is used to track the disconnect switch phase B closed position as above for phase A.
• SWITCH 1 B OPENED: If the mode is selected as three-pole, this setting has no function. If the mode is selected as
single-pole, this input is used to track the disconnect switch phase B opened position as above for phase A.
• SWITCH 1 C CLOSED: If the mode is selected as three-pole, this setting has no function. If the mode is selected as
single-pole, this input is used to track the disconnect switch phase C closed position as above for phase A. 5
• SWITCH 1 C OPENED: If the mode is selected as three-pole, this setting has no function. If the mode is selected as
single-pole, this input is used to track the disconnect switch phase C opened position as above for phase A.
• SWITCH 1 Toperate: This setting specifies the required interval to overcome transient disagreement between the 52/a
and 52/b auxiliary contacts during disconnect switch operation. If transient disagreement still exists after this time has
expired, the SWITCH 1 BAD STATUS FlexLogic™ operand is asserted from alarm or blocking purposes.
• SWITCH 1 ALARM DELAY: This setting specifies the delay interval during which a disagreement of status among the
three-pole position tracking operands will not declare a pole disagreement. This allows for non-simultaneous operation
of the poles.
IEC 61850 functionality is permitted when the T60 is in “Programmed” mode and not in the local control mode.

5.4.7 FLEXCURVES™
a) SETTINGS
PATH: SETTINGS SYSTEM SETUP FLEXCURVES FLEXCURVE A(D)
FlexCurves™ A through D have settings for entering times to reset and operate at the following pickup levels: 0.00 to 0.98
and 1.03 to 20.00. This data is converted into two continuous curves by linear interpolation between data points. To enter a
custom FlexCurve™, enter the reset and operate times (using the VALUE keys) for each selected pickup point (using the
MESSAGE UP/DOWN keys) for the desired protection curve (A, B, C, or D).
The relay using a given FlexCurve™ applies linear approximation for times between the user-entered
points. Special care must be applied when setting the two points that are close to the multiple of pickup of
NOTE
1; that is, 0.98 pu and 1.03 pu. It is recommended to set the two times to a similar value; otherwise, the lin-
ear approximation may result in undesired behavior for the operating quantity that is close to 1.00 pu.
Addr: Adds the time specified in this field (in ms) to each
curve operating time value.
d) EXAMPLE
A composite curve can be created from the GE_111 standard with MRT = 200 ms and HCT initially disabled and then
enabled at eight (8) times pickup with an operating time of 30 ms. At approximately four (4) times pickup, the curve operat-
ing time is equal to the MRT and from then onwards the operating time remains at 200 ms (see below).

UR Synchrophasor Implementation
PHASORS are used within protection relays. If these phasors are referenced to a common time base they are referred to as
a SYNCHROPHASOR. A vastly improved method for tracking power system dynamic phenomena for improved power system
monitoring, protection, operation, and control can be realized if Synchrophasors from different locations within the power
system are networked to a central location. The complete Synchrophasor implementation for Firmware version 6.0 is
shown in the figure below.
Depending on the applied filter, the Synchrophasors that are produced are classified as either P (protection) or M (meter-
ing) class Synchrophasors as described in the latest C37.118 standard. Sychrophasors available within the UR that have
no filtering applied are classified as NONE. Depending on the model number, the UR can support up to a maximum of three
DSP’s. The four PMUs within the UR can be configured to read the sychrophasors from any of the six sources at a user
programmable rate. When one source is selected by one PMU it cannot be used in other PMUs. In firmware version 6.0 a
maximum of two aggregators allow the user to aggregate selected PMUs as per IEC 37.118 to form a custom data set that
is sent to a client optimizing bandwidth. As with sources, a given aggregator can aggregate data form PMUs with the same
rate. With firmware 6.0 a maximum of two PMUs can be set to a reporting rate of 120 Hz for a 60 Hz system (or 100Hz for
a 50 Hz system) and each aggregator can be configured to support a TCP or a UDP connection to a client allowing the UR
to support a total of two TCP connections or two UDP connections or a combination of a TCP and a UDP connection per
aggregator for real-time data reporting. Also note that if hard fiber is used it will have no impact on this specification.
Precise IRIG-B input is vital for correct synchrophasor measurement and reporting. A DC level shift IRIG-B receiver
must be used for the phasor measurement unit to output proper synchrophasor values.

This section contains basic phasor measurement unit (PMU) data, such as functions, source settings, and names.
• PMU 1 FUNCTION: This setting enables the PMU 1 functionality. Any associated functions (such as the recorder or
triggering comparators) will not function if this setting is “Disabled”. Use this setting to permanently enable or disable
the feature.
• PMU 1 IDCODE: This setting assigns a numerical ID to the PMU. It corresponds to the IDCODE field of the data, con-
figuration, header, and command frames of the C37.118 protocol. The PMU uses this value when sending data, config-
uration, and header frames; and it responds to this value when receiving the command frame. This is used when only
data from one PMU is present.
• PMU 1 STN: This setting assigns an alphanumeric ID to the PMU station. It corresponds to the STN field of the config-
uration frame of the C37.118 protocol. This value is a 16-character ASCII string as per the C37.118 standard.
• PMU 1 SIGNAL SOURCE: This setting specifies one of the available T60 signal sources for processing in the PMU.
Note that any combination of voltages and currents can be configured as a source. The current channels could be con-
figured as sums of physically connected currents. This facilitates PMU applications in breaker-and-a-half, ring-bus, and
similar arrangements. The PMU feature calculates voltage phasors for actual voltage (A, B, C, and auxiliary) and cur-
rent (A, B, C, and ground) channels of the source, as well as symmetrical components (0, 1, and 2) of both voltages
and currents. When configuring communication and recording features of the PMU, the user could select – from the
5
above superset – the content to be sent out or recorded. When one source is selected by one PMU, it cannot be
selected by another PMU.
• PMU 1 CLASS (Range P, M, None): This setting selects the synchrophasor class. Note that a reporting rate of 100 or
120 can only be selected for class P synchrophasors and if the system frequency is 50 Hz or 60 Hz, respectively.
• PMU 1 NETWORK REPORTING FORMAT: This setting selects whether synchrophasors are reported as 16-bit inte-
gers or 32-bit IEEE floating point numbers. This setting complies with bit-1 of the FORMAT field of the C37.118 config-
uration frame. Note that this setting applies to synchrophasors only; the user-selectable FlexAnalog™ channels are
always transmitted as 16-bit integer values.
• PMU 1 NETWORK REPORTING STYLE: This setting selects whether synchrophasors are reported in rectangular
(real and imaginary) coordinates or in polar (magnitude and angle) coordinates. This setting complies with bit-0 of the
FORMAT field of the C37.118 configuration frame.
• PMU 1 REPORTING RATE: This setting specifies the reporting rate for the network (Ethernet) port. This value applies
to all PMU streams of the device that are assigned to transmit over this aggregator. For a system frequency of 60 Hz
(50 Hz), the T60 will generate a reporting mismatch message if the selected rate is not set as 10 Hz, 12 Hz, 15 Hz,
20 Hz, 30 Hz, 60 Hz, or 120 Hz (or 10 Hz, 25 Hz, 50 Hz or 100 Hz when the system frequency is 50 Hz) when entered
via the keypad or software; and the T60 will stop the transmission of reports. See the tables below for additional detail.
Note that for firmware 6.0 a maximum of two PMUs can be set to a reporting rate of 120 Hz for a 60 Hz system (or
100 Hz for 50 Hz system).

These settings allow for optimizing the frame size and maximizing transmission channel usage, depending on a given
application. Select “Off” to suppress transmission of a given value.
• PMU1 PHS-1 NM to PMU1 PHS-14 NM: These settings allow for custom naming of the synchrophasor channels. Six-
teen-character ASCII strings are allowed as in the CHNAM field of the configuration frame. These names are typically
based on station, bus, or breaker names.
• PMU1 A-CH-1 to PMU1 A-CH-16: These settings specify any analog data measured by the relay to be included as a
user-selectable analog channel of the data frame. Up to eight analog channels can be configured to send any FlexAn-
alog value from the relay. Examples include active and reactive power, per phase or three-phase power, power factor,
temperature via RTD inputs, and THD. The configured analog values are sampled concurrently with the synchrophasor
instant and sent as 16-bit integer values.
• PMU1 A-CH-1 NM to PMU1 A-CH-16 NM: These settings allow for custom naming of the analog channels. Sixteen-
character ASCII strings are allowed as in the CHNAM field of the configuration frame.
• PMU1 D-CH-1 to PMU1 D-CH-16: These settings specify any digital flag measured by the relay to be included as a
user-selectable digital channel of the data frame. Up to sixteen digital channels can be configured to send any Flex-
Logic operand from the relay. The configured digital flags are sampled concurrently with the synchrophasor instant.
These values are mapped into a two-byte integer number, with byte 1 LSB corresponding to the digital channel 1and
byte 2 MSB corresponding to digital channel 16.
• PMU1 D-CH-1 NM to PMU1 D-CH-16 NM: These settings allow for custom naming of the digital channels. Sixteen-
character ASCII strings are allowed as in the CHNAM field of the configuration frame.
• PMU1 D-CH-1 NORMAL STATE to PMU1 D-CH-16 NORMAL STATE: These settings allow for specifying a normal
state for each digital channel. These states are transmitted in configuration frames to the data concentrator.
c) AGGREGATORS
PATH: SETTINGS PRODUCT SETUP SYSTEM SETUP PHASOR MEASUREMENT PMU AGGREGATORS 1
• PMU AGGREGATOR1 IDCODE: This setting specifies an IDCODE for the aggregator. Individual PMU data streams
transmitted over this port are identified via their own IDCODES, as per the PMU IDCODE settings. This IDCODE is to
be used by the command frame to start/stop transmission, and request configuration.
• PMU AGGREGATOR1 PROTOCOL: This setting selects if C37.118 or the new IEC61850 standard will be used. In
firmware release 6.0 only C37.118 will be available.
• PMU AGGREGATOR1: TCP PORT: This setting selects the TCP port number that will be used by this aggregator for
network reporting. When using more than one aggregator, the default value of the port must be properly changed to
avoid port number collisions.
• PMU AGGREGATOR1 UDP PORT: This setting selects the UDP port number that will be used by this aggregator for
network reporting. When using more than one aggregator, the default value of the port must be properly changed to
avoid port number collisions.
• PMU AGGREGATOR1 PDC CONTROL: The synchrophasor standard allows for user-defined controls originating at
the PDC, to be executed on the PMU. The control is accomplished via an extended command frame. The relay
decodes the first word of the extended field, EXTFRAME, to drive 16 dedicated FlexLogic operands. Each aggregator
supports 16 FlexLogic operands as shown in table 2. The operands are asserted for 5 seconds following reception of
the command frame. If the new command frame arrives within the 5 second period, the FlexLogic operands are
updated, and the 5 second timer is re-started. This setting enables or disables the control. When enabled, all 16 oper-
ands for each aggregator are active; when disabled all 16 operands for each aggregator remain reset.
• PMU AGGREGATOR1 PMU1 to PMU4: If set to Yes aggregator 1 will include PMU1 data set in the reporting data
stream. Aggregator 1 will not include PMU1 data set in the report if set to No. For a system frequency of 60Hz (50 Hz)
the UR will generate a Reporting Mismatch message if the selected rate isn’t 10Hz, 12Hz, 15Hz, 20Hz, 30Hz, 60 Hz,
120 Hz (10Hz, 25Hz, 50Hz or 100Hz) when entered via the keypad or software and the UR will stop the transmission
of reports. Note: If changes are made to PMU settings the PMU must be removed from the aggregator and the settings
5
saved and then the PMU should be added back into the aggregator and the settings saved such that the new PMU set-
tings take effect.
d) CALIBRATION
PATH: SETTINGS SYSTEM SETUP PHASOR MEASUREMENT UNIT PHASOR MEASUREMENT UNIT 1 PMU 1 (to 4)
CALIBRATION
This menu contains user angle and magnitude calibration data for the phasor measurement unit (PMU). This data is com-
bined with the factory adjustments to shift the phasors for better accuracy.
• PMU 1 VA... IG CALIBRATION ANGLE: These settings recognize applications with protection class voltage and cur-
rent sources, and allow the user to calibrate each channel (four voltages and four currents) individually to offset errors
introduced by VTs, CTs, and cabling. The setting values are effectively added to the measured angles. Therefore, enter
a positive correction of the secondary signal lags the true signal; and negative value if the secondary signal leads the
true signal.
• PMU 1 VA... IG CALIBRATION MAGNITUDE: These settings recognize applications with protection class voltage and
current sources, and allow the user to calibrate each channel (four voltages and four currents) individually to offset
errors introduced by VTs, CTs. The setting values are effectively a multiplier of the measured magnitudes. Therefore,
enter a multiplier greater then 100% of the secondary signal increases the true signal; and a multiplier less than 100%
value of the secondary signal reduces the true signal.
• PMU 1 SEQ VOLT SHIFT ANGLE: This setting allows correcting positive- and negative-sequence voltages for vector
groups of power transformers located between the PMU voltage point, and the reference node. This angle is effectively
added to the positive-sequence voltage angle, and subtracted from the negative-sequence voltage angle. Note that:
1. When this setting is not “0°”, the phase and sequence voltages will not agree. Unlike sequence voltages, the
phase voltages cannot be corrected in a general case, and therefore are reported as measured.
2. When receiving synchrophasor date at multiple locations, with possibly different reference nodes, it may be more
beneficial to allow the central locations to perform the compensation of sequence voltages.
3. This setting applies to PMU data only. The T60 calculates symmetrical voltages independently for protection and
control purposes without applying this correction.
4. When connected to line-to-line voltages, the PMU calculates symmetrical voltages with the reference to the AG
voltage, and not to the physically connected AB voltage (see the Metering Conventions section in Chapter 6).
• PMU 1 SEQ CURR SHIFT ANGLE: This setting allows correcting positive and negative-sequence currents for vector
groups of power transformers located between the PMU current point and the reference node. The setting has the
same meaning for currents as the PMU 1 SEQ VOLT SHIFT ANGLE setting has for voltages. Normally, the two correcting
angles are set identically, except rare applications when the voltage and current measuring points are located at differ-
ent windings of a power transformer.
Each logical phasor measurement unit (PMU) contains five triggering mechanisms to facilitate triggering of the associated
PMU recorder, or cross-triggering of other PMUs of the system. They are:
• Overfrequency and underfrequency.
• Overvoltage and undervoltage.
• Overcurrent.
• Overpower.
• High rate of change of frequency.
The pre-configured triggers could be augmented with a user-specified condition built freely using programmable logic of the
relay. The entire triggering logic is refreshed once every two power system cycles.
All five triggering functions and the user-definable condition are consolidated (ORed) and connected to the PMU recorder.
Each trigger can be programmed to log its operation into the event recorder, and to signal its operation via targets. The five
triggers drive the STAT bits of the data frame to inform the destination of the synchrophasor data regarding the cause of
trigger. The following convention is adopted to drive bits 11, 3, 2, 1, and 0 of the STAT word.

g) FREQUENCY TRIGGERING
PATH: SETTINGS SYSTEM SETUP PHASOR MEASUREMENT... PMU 1 TRIGGERING PMU 1 FREQUENCY TRIGGER
The trigger responds to the frequency signal of the phasor measurement unit (PMU) source. The frequency is calculated
from either phase voltages, auxiliary voltage, phase currents and ground current, in this hierarchy, depending on the source
configuration as per T60 standards. This element requires the frequency is above the minimum measurable value. If the
frequency is below this value, such as when the circuit is de-energized, the trigger will drop out.
• PMU 1 FREQ TRIGGER LOW-FREQ: This setting specifies the low threshold for the abnormal frequency trigger. The
comparator applies a 0.03 Hz hysteresis.
• PMU 1 FREQ TRIGGER HIGH-FREQ: This setting specifies the high threshold for the abnormal frequency trigger. The
comparator applies a 0.03 Hz hysteresis.
• PMU 1 FREQ TRIGGER PKP TIME: This setting could be used to filter out spurious conditions and avoid unnecessary
triggering of the recorder.
• PMU 1 FREQ TRIGGER DPO TIME: This setting could be used to extend the trigger after the situation returned to nor-
mal. This setting is of particular importance when using the recorder in the forced mode (recording as long as the trig-
gering condition is asserted).

AB, BC, and CA) are processed independently and could trigger the recorder. A minimum voltage supervision of 0.1 pu is
implemented to prevent pickup on a de-energized circuit, similarly to the undervoltage protection element.
• PMU 1 VOLT TRIGGER LOW-VOLT: This setting specifies the low threshold for the abnormal voltage trigger, in per-
unit of the PMU source. 1 pu is a nominal voltage value defined as the nominal secondary voltage times VT ratio. The
comparator applies a 3% hysteresis.

This element responds to abnormal power. Separate thresholds are provided for active, reactive, and apparent powers. In
terms of signaling its operation the element does not differentiate between the three types of power. The trigger responds to
the single-phase and three-phase power signals of the phasor measurement unit (PMU) source.
• PMU 1 POWER TRIGGER ACTIVE: This setting specifies the pickup threshold for the active power of the source. For
single-phase power, 1 pu is a product of 1 pu voltage and 1 pu current, or the product of nominal secondary voltage,
the VT ratio and the nominal primary current. For the three-phase power, 1 pu is three times that for a single-phase

• PMU 1 POWER TRIGGER REACTIVE: This setting specifies the pickup threshold for the reactive power of the
source. For single-phase power, 1 pu is a product of 1 pu voltage and 1 pu current, or the product of nominal second-

records. As the number of records is increased the available storage for each record is reduced. The relay supports a
maximum of 128 records in either timed or forced mode.
• PMU 1 TRIGGER MODE: This setting specifies what happens when the recorder uses its entire available memory
storage. Under the “Automatic Overwrite”, the last record is erased to facilitate new recording, when triggered. Under
the “Protected” selection, the recorder stops creating new records when the entire memory is used up by the old un-
cleared records.
5 • PMU 1 TIMED TRIGGER POSITION: This setting specifies the amount of pre-trigger data as a percent of the entire
record. This setting applies only to the timed mode of recording.
m) NETWORK CONNECTION
PATH: SETTINGS SYSTEM SETUP PHASOR... PHASOR MEASUREMENT UNIT 1(4) REPORTING OVER NETWORK
The Ethernet connection works simultaneously with other communication means working over the Ethernet and is config-
ured as follows. Up to three clients can be simultaneously supported.
• NETWORK REPORTING IDCODE: This setting specifies an IDCODE for the entire port. Individual PMU streams
transmitted over this port are identified via their own IDCODES as per the device settings. This IDCODE is to be used
by the command frame to start or stop transmission, and request configuration or header frames.
• NETWORK REPORTING RATE: This setting specifies the reporting rate for the network (Ethernet) port. This value
applies to all PMU streams of the device that are assigned to transmit over this port.
• NETWORK REPORTING STYLE: This setting selects between reporting synchrophasors in rectangular (real and
imaginary) or in polar (magnitude and angle) coordinates. This setting complies with bit-0 of the format field of the
C37.118 configuration frame.
• NETWORK REPORTING FORMAT: This setting selects between reporting synchrophasors as 16-bit integer or 32-bit
IEEE floating point numbers. This setting complies with bit 1 of the format field of the C37.118 configuration frame.
Note that this setting applies to synchrophasors only – the user-selectable FlexAnalog channels are always transmit-
ted as 32-bit floating point numbers.
• NETWORK PDC CONTROL: The synchrophasor standard allows for user-defined controls originating at the PDC, to
be executed on the PMU. The control is accomplished via an extended command frame. The relay decodes the first
word of the extended field, EXTFRAME, to drive 16 dedicated FlexLogic operands: PDC NETWORK CNTRL 1 (from the
least significant bit) to PDC NETWORK CNTRL 16 (from the most significant bit). Other words, if any, in the EXTFRAME
are ignored. The operands are asserted for 5 seconds following reception of the command frame. If the new command
frame arrives within the 5 second period, the FlexLogic™ operands are updated, and the 5 second timer is re-started.
This setting enables or disables the control. When enabled, all 16 operands are active; when disabled all 16 operands
remain reset.
• NETWORK TCP PORT: This setting selects the TCP port number that will be used for network reporting.
• NETWORK UDP PORT 1: This setting selects the first UDP port that will be used for network reporting.
• NETWORK UDP PORT 2: This setting selects the second UDP port that will be used for network reporting. 5
To provide maximum flexibility to the user, the arrangement of internal digital logic combines fixed and user-programmed
parameters. Logic upon which individual features are designed is fixed, and all other logic, from digital input signals through
elements or combinations of elements to digital outputs, is variable. The user has complete control of all variable logic
through FlexLogic™. In general, the system receives analog and digital inputs which it uses to produce analog and digital
outputs. The major sub-systems of a generic UR-series relay involved in this process are shown below.
The logic that determines the interaction of inputs, elements, schemes and outputs is field programmable through the use
of logic equations that are sequentially processed. The use of virtual inputs and outputs in addition to hardware is available
internally and on the communication ports for other relays to use (distributed FlexLogic™).
FlexLogic™ allows users to customize the relay through a series of equations that consist of operators and operands. The
operands are the states of inputs, elements, schemes and outputs. The operators are logic gates, timers and latches (with
set and reset inputs). A system of sequential operations allows any combination of specified operands to be assigned as
inputs to specified operators to create an output. The final output of an equation is a numbered register called a virtual out-
put. Virtual outputs can be used as an input operand in any equation, including the equation that generates the output, as a
seal-in or other type of feedback.
A FlexLogic™ equation consists of parameters that are either operands or operators. Operands have a logic state of 1 or 0.
Operators provide a defined function, such as an AND gate or a Timer. Each equation defines the combinations of parame-
ters to be used to set a Virtual Output flag. Evaluation of an equation results in either a 1 (=ON, i.e. flag set) or 0 (=OFF, i.e.
flag not set). Each equation is evaluated at least 4 times every power system cycle.
Some types of operands are present in the relay in multiple instances; e.g. contact and remote inputs. These types of oper-
ands are grouped together (for presentation purposes only) on the faceplate display. The characteristics of the different
types of operands are listed in the table below.
The operands available for this relay are listed alphabetically by types in the following table.

RESETTING RESET OP Reset command is operated (set by all three operands below).
RESET OP (COMMS) Communications source of the reset command.
RESET OP (OPERAND) Operand (assigned in the INPUTS/OUTPUTS RESETTING menu) source
of the reset command.
RESET OP (PUSHBUTTON) Reset key (pushbutton) source of the reset command.
Some operands can be re-named by the user. These are the names of the breakers in the breaker control feature, the ID
(identification) of contact inputs, the ID of virtual inputs, and the ID of virtual outputs. If the user changes the default name
or ID of any of these operands, the assigned name will appear in the relay list of operands. The default names are shown in
the FlexLogic™ operands table above.
The characteristics of the logic gates are tabulated below, and the operators available in FlexLogic™ are listed in the Flex-
Logic™ operators table.
When forming a FlexLogic™ equation, the sequence in the linear array of parameters must follow these general rules:
1. Operands must precede the operator which uses the operands as inputs.
2. Operators have only one output. The output of an operator must be used to create a virtual output if it is to be used as
an input to two or more operators.
3. Assigning the output of an operator to a virtual output terminates the equation.
4. A timer operator (for example, "TIMER 1") or virtual output assignment (for example, " = Virt Op 1") may only be used
once. If this rule is broken, a syntax error will be declared.
Each equation is evaluated in the order in which the parameters have been entered.
FlexLogic™ provides latches which by definition have a memory action, remaining in the set state after the
set input has been asserted. However, they are volatile; that is, they reset on the re-application of control
NOTE power.
When making changes to settings, all FlexLogic™ equations are re-compiled whenever any new setting
value is entered, so all latches are automatically reset. If it is necessary to re-initialize FlexLogic™ during
testing, for example, it is suggested to power the unit down and then back up.
This section provides an example of implementing logic for a typical application. The sequence of the steps is quite impor-
tant as it should minimize the work necessary to develop the relay settings. Note that the example presented in the figure
below is intended to demonstrate the procedure, not to solve a specific application situation.
In the example below, it is assumed that logic has already been programmed to produce virtual outputs 1 and 2, and is only
a part of the full set of equations used. When using FlexLogic™, it is important to make a note of each virtual output used –
a virtual output designation (1 to 96) can only be properly assigned once.

5 1. Inspect the example logic diagram to determine if the required logic can be implemented with the FlexLogic™ opera-
tors. If this is not possible, the logic must be altered until this condition is satisfied. Once this is done, count the inputs
to each gate to verify that the number of inputs does not exceed the FlexLogic™ limits, which is unlikely but possible. If
the number of inputs is too high, subdivide the inputs into multiple gates to produce an equivalent. For example, if 25
inputs to an AND gate are required, connect Inputs 1 through 16 to AND(16), 17 through 25 to AND(9), and the outputs
from these two gates to AND(2).
Inspect each operator between the initial operands and final virtual outputs to determine if the output from the operator
is used as an input to more than one following operator. If so, the operator output must be assigned as a virtual output.
For the example shown above, the output of the AND gate is used as an input to both OR#1 and Timer 1, and must
therefore be made a virtual output and assigned the next available number (i.e. Virtual Output 3). The final output must
also be assigned to a virtual output as virtual output 4, which will be programmed in the contact output section to oper-
ate relay H1 (that is, contact output H1).
Therefore, the required logic can be implemented with two FlexLogic™ equations with outputs of virtual output 3 and
virtual output 4 as shown below.

2. Prepare a logic diagram for the equation to produce virtual output 3, as this output will be used as an operand in the
virtual output 4 equation (create the equation for every output that will be used as an operand first, so that when these
operands are required they will already have been evaluated and assigned to a specific virtual output). The logic for
virtual output 3 is shown below with the final output assigned.

98: The gate preceding the output is an AND, which in this case requires two inputs. The operator for this gate is a 2-
input AND so the parameter is “AND(2)”. Note that FlexLogic™ rules require that the number of inputs to most
types of operators must be specified to identify the operands for the gate. As the 2-input AND will operate on the
two operands preceding it, these inputs must be specified, starting with the lower.
97: This lower input to the AND gate must be passed through an inverter (the NOT operator) so the next parameter is
“NOT”. The NOT operator acts upon the operand immediately preceding it, so specify the inverter input next.
96: The input to the NOT gate is to be contact input H1c. The ON state of a contact input can be programmed to be
set when the contact is either open or closed. Assume for this example the state is to be ON for a closed contact.
The operand is therefore “Cont Ip H1c On”.
95: The last step in the procedure is to specify the upper input to the AND gate, the operated state of digital element 2.
This operand is "DIG ELEM 2 OP".
Writing the parameters in numerical order can now form the equation for virtual output 3:
[95] DIG ELEM 2 OP
[96] Cont Ip H1c On
[97] NOT
[98] AND(2)
[99] = Virt Op 3
It is now possible to check that this selection of parameters will produce the required logic by converting the set of parame-
ters into a logic diagram. The result of this process is shown below, which is compared to the logic for virtual output 3 dia-
gram as a check.

In the expression above, the virtual output 4 input to the four-input OR is listed before it is created. This is typical of a
form of feedback, in this case, used to create a seal-in effect with the latch, and is correct.
8. The logic should always be tested after it is loaded into the relay, in the same fashion as has been used in the past.
Testing can be simplified by placing an "END" operator within the overall set of FlexLogic™ equations. The equations
will then only be evaluated up to the first "END" operator.
The "On" and "Off" operands can be placed in an equation to establish a known set of conditions for test purposes, and
the "INSERT" and "DELETE" commands can be used to modify equations.
There are 512 FlexLogic™ entries available, numbered from 1 to 512, with default END entry settings. If a "Disabled" Ele-
ment is selected as a FlexLogic™ entry, the associated state flag will never be set to ‘1’. The ‘+/–‘ key may be used when
editing FlexLogic™ equations from the keypad to quickly scan through the major parameter types.
There are 32 identical FlexLogic™ timers available. These timers can be used as operators for FlexLogic™ equations.
• TIMER 1 TYPE: This setting is used to select the time measuring unit.
• TIMER 1 PICKUP DELAY: Sets the time delay to pickup. If a pickup delay is not required, set this function to "0".
• TIMER 1 DROPOUT DELAY: Sets the time delay to dropout. If a dropout delay is not required, set this function to "0".
5.5.7 FLEXELEMENTS™
A FlexElement™ is a universal comparator that can be used to monitor any analog actual value calculated by the relay or a
net difference of any two analog actual values of the same type. The effective operating signal could be treated as a signed
number or its absolute value could be used as per user's choice.
The element can be programmed to respond either to a signal level or to a rate-of-change (delta) over a pre-defined period
of time. The output operand is asserted when the operating signal is higher than a threshold or lower than a threshold as
per user's choice.

The FLEXELEMENT 1 PICKUP setting specifies the operating threshold for the effective operating signal of the element. If set
to “Over”, the element picks up when the operating signal exceeds the FLEXELEMENT 1 PICKUP value. If set to “Under”, the
element picks up when the operating signal falls below the FLEXELEMENT 1 PICKUP value.
The FLEXELEMENT 1 HYSTERESIS setting controls the element dropout. It should be noticed that both the operating signal
and the pickup threshold can be negative facilitating applications such as reverse power alarm protection. The FlexEle-
ment™ can be programmed to work with all analog actual values measured by the relay. The FLEXELEMENT 1 PICKUP set-
ting is entered in per-unit values using the following definitions of the base units:
The FLEXELEMENT 1 HYSTERESIS setting defines the pickup–dropout relation of the element by specifying the width of the
hysteresis loop as a percentage of the pickup value as shown in the FlexElement™ direction, pickup, and hysteresis dia-
gram.
The FLEXELEMENT 1 DT UNIT setting specifies the time unit for the setting FLEXELEMENT 1 dt. This setting is applicable only if
FLEXELEMENT 1 COMP MODE is set to “Delta”. The FLEXELEMENT 1 DT setting specifies duration of the time interval for the
rate of change mode of operation. This setting is applicable only if FLEXELEMENT 1 COMP MODE is set to “Delta”.
This FLEXELEMENT 1 PKP DELAY setting specifies the pickup delay of the element. The FLEXELEMENT 1 RST DELAY setting
specifies the reset delay of the element.
The non-volatile latches provide a permanent logical flag that is stored safely and will not reset upon reboot after the relay
is powered down. Typical applications include sustaining operator commands or permanently block relay functions, such as
Autorecloser, until a deliberate interface action resets the latch. The settings element operation is described below:
• LATCH 1 TYPE: This setting characterizes Latch 1 to be Set- or Reset-dominant.
• LATCH 1 SET: If asserted, the specified FlexLogic™ operands 'sets' Latch 1.
• LATCH 1 RESET: If asserted, the specified FlexLogic™ operand 'resets' Latch 1. 5

Each protection element can be assigned up to six different sets of settings according to setting group designations 1 to 6.
The performance of these elements is defined by the active setting group at a given time. Multiple setting groups allow the
user to conveniently change protection settings for different operating situations (for example, altered power system config-
uration, season of the year, etc.). The active setting group can be preset or selected via the SETTING GROUPS menu (see the
Control elements section later in this chapter). See also the Introduction to elements section at the beginning of this chap-
ter.
Each of the six setting group menus is identical. Setting group 1 (the default active group) automatically becomes active if
no other group is active (see the Control elements section for additional details).
5.6.3 DISTANCE
MESSAGE
GROUND DISTANCE Z2
See page 5–153. 5
GROUND DISTANCE Z3
MESSAGE See page 5–153.
Four common settings are available for distance protection. The DISTANCE SOURCE identifies the signal source for all dis-
tance functions. The mho distance functions use a dynamic characteristic: the positive-sequence voltage – either memo-
rized or actual – is used as a polarizing signal. The memory voltage is also used by the built-in directional supervising
functions applied for both the mho and quad characteristics.
The MEMORY DURATION setting specifies the length of time a memorized positive-sequence voltage should be used in the
distance calculations. After this interval expires, the relay checks the magnitude of the actual positive-sequence voltage. If
it is higher than 10% of the nominal, the actual voltage is used, if lower – the memory voltage continues to be used.
The memory is established when the positive-sequence voltage stays above 80% of its nominal value for five power system
cycles. For this reason it is important to ensure that the nominal secondary voltage of the VT is entered correctly under the
SETTINGS SYSTEM SETUP AC INPUTS VOLTAGE BANK menu.
Set MEMORY DURATION long enough to ensure stability on close-in reverse three-phase faults. For this purpose, the maxi-
mum fault clearing time (breaker fail time) in the substation should be considered. On the other hand, the MEMORY DURA-
TION cannot be too long as the power system may experience power swing conditions rotating the voltage and current
phasors slowly while the memory voltage is static, as frozen at the beginning of the fault. Keeping the memory in effect for
too long may eventually lead to incorrect operation of the distance functions.
The distance zones can be forced to become self-polarized through the FORCE SELF-POLAR setting. Any user-selected con-
dition (FlexLogic™ operand) can be configured to force self-polarization. When the selected operand is asserted (logic 1),
the distance functions become self-polarized regardless of other memory voltage logic conditions. When the selected oper-
and is de-asserted (logic 0), the distance functions follow other conditions of the memory voltage logic as shown below.
The distance zones can be forced to become memory-polarized through the FORCE MEM-POLAR setting. Any user-selected
condition (any FlexLogic™ operand) can be configured to force memory polarization. When the selected operand is
asserted (logic 1), the distance functions become memory-polarized regardless of the positive-sequence voltage magni-
tude at this time. When the selected operand is de-asserted (logic 0), the distance functions follow other conditions of the
memory voltage logic.
The FORCE SELF-POLAR and FORCE MEM-POLAR settings should never be asserted simultaneously. If this happens, the logic
will give higher priority to forcing self-polarization as indicated in the logic below. This is consistent with the overall philoso-
phy of distance memory polarization.
The memory polarization cannot be applied permanently but for a limited time only; the self-polarization may be
applied permanently and therefore should take higher priority.

5 PATH: SETTINGS GROUPED ELEMENTS SETTING GROUP 1(6) DISTANCE PHASE DISTANCE Z1(Z3)
Three zones of phase distance protection with a minimum 150 ms time delay are provided as backup protection for trans-
5
formers or adjacent lines.
The phase mho distance function uses a dynamic 100% memory-polarized mho characteristic with additional reactance,
directional, and overcurrent supervising characteristics. When set to “Non-directional”, the mho function becomes an offset
mho with the reverse reach controlled independently from the forward reach, and all the directional characteristics
removed.
The phase quadrilateral distance function is comprised of a reactance characteristic, right and left blinders, and 100%
memory-polarized directional and current supervising characteristics. When set to “Non-directional”, the quadrilateral func-
tion applies a reactance line in the reverse direction instead of the directional comparators. Refer to Chapter 8 for additional
information.
Each phase distance zone is configured individually through its own setting menu. All of the settings can be independently
modified for each of the zones except:
1. The SIGNAL SOURCE setting (common for the distance elements of all zones as entered under SETTINGS GROUPED
ELEMENTS SETTING GROUP 1(6) DISTANCE).
2. The MEMORY DURATION setting (common for the distance elements of all zones as entered under SETTINGS
GROUPED ELEMENTS SETTING GROUP 1(6) DISTANCE).
The common distance settings described earlier must be properly chosen for correct operation of the phase distance ele-
ments. Additional details may be found in chapter 8: Theory of operation.
Although all zones can be used as either instantaneous elements (pickup [PKP] and dropout [DPO] FlexLogic™ operands)
or time-delayed elements (operate [OP] FlexLogic™ operands), only zone 1 is intended for the instantaneous under-reach-
ing tripping mode.
Ensure that the PHASE VT SECONDARY VOLTAGE setting (see the SETTINGS SYSTEM SETUP AC INPUTS
VOLTAGE BANK menu) is set correctly to prevent improper operation of associated memory action.

• PHS DIST Z1 DIR: All phase distance zones are reversible. The forward direction is defined by the PHS DIST Z1 RCA
setting, whereas the reverse direction is shifted 180° from that angle. The non-directional zone spans between the for-
ward reach impedance defined by the PHS DIST Z1 REACH and PHS DIST Z1 RCA settings, and the reverse reach imped-
ance defined by PHS DIST Z1 REV REACH and PHS DIST Z1 REV REACH RCA as illustrated below.
• PHS DIST Z1 SHAPE: This setting selects the shape of the phase distance function between the mho and quadrilat-
eral characteristics. The selection is available on a per-zone basis. The two characteristics and their possible varia-
tions are shown in the following figures.

• PHS DIST Z1 XFMR VOL CONNECTION: The phase distance elements can be applied to look through a three-phase
delta-wye or wye-delta power transformer. In addition, VTs and CTs could be located independently from one another
at different windings of the transformer. If the potential source is located at the correct side of the transformer, this set-
ting shall be set to “None”.
This setting specifies the location of the voltage source with respect to the involved power transformer in the direction
of the zone. The following figure illustrates the usage of this setting. In section (a), zone 1 is looking through a trans-
former from the delta into the wye winding. Therefore, the Z1 setting shall be set to “Dy11”. In section (b), Zone 3 is
looking through a transformer from the wye into the delta winding. Therefore, the Z3 setting shall be set to “Yd1”. The
zone is restricted by the potential point (location of the VTs) as illustrated in Figure (e).
• PHS DIST Z1 XFMR CUR CONNECTION: This setting specifies the location of the current source with respect to the
involved power transformer in the direction of the zone. In section (a) of the following figure, zone 1 is looking through
a transformer from the delta into the wye winding. Therefore, the Z1 setting shall be set to “Dy11”. In section (b), the
CTs are located at the same side as the read point. Therefore, the Z3 setting shall be set to “None”.

lating distance reach settings in applications involving power transformers.

• PHS DIST Z1 REV REACH: This setting defines the reverse reach of the zone set to non-directional (PHS DIST Z1 DIR
setting). The value must be entered in secondary ohms. This setting does not apply when the zone direction is set to
“Forward” or “Reverse”.
• PHS DIST Z1 REV REACH RCA: This setting defines the angle of the reverse reach impedance if the zone is set to
non-directional (PHS DIST Z1 DIR setting). This setting does not apply when the zone direction is set to “Forward” or
“Reverse”.
• PHS DIST Z1 COMP LIMIT: This setting shapes the operating characteristic. In particular, it produces the lens-type
characteristic of the mho function and a tent-shaped characteristic of the reactance boundary of the quadrilateral func-
tion. If the mho shape is selected, the same limit angle applies to both the mho and supervising reactance compara-
tors. In conjunction with the mho shape selection, the setting improves loadability of the protected line. In conjunction
with the quadrilateral characteristic, this setting improves security for faults close to the reach point by adjusting the
reactance boundary into a tent-shape.
• PHS DIST Z1 DIR RCA: This setting selects the characteristic angle (or maximum torque angle) of the directional
supervising function. If the mho shape is applied, the directional function is an extra supervising function as the
dynamic mho characteristic is itself directional. In conjunction with the quadrilateral shape, this setting defines the only
directional function built into the phase distance element. The directional function uses the memory voltage for polar-
ization. This setting typically equals the distance characteristic angle PHS DIST Z1 RCA.
• PHS DIST Z1 DIR COMP LIMIT: Selects the comparator limit angle for the directional supervising function.
• PHS DIST Z1 QUAD RGT BLD: This setting defines the right blinder position of the quadrilateral characteristic along
the resistive axis of the impedance plane (see the Quadrilateral distance characteristic figures). The angular position of
the blinder is adjustable with the use of the PHS DIST Z1 QUAD RGT BLD RCA setting. This setting applies only to the
quadrilateral characteristic and should be set giving consideration to the maximum load current and required resistive
coverage.
5 • PHS DIST Z1 QUAD RGT BLD RCA: This setting defines the angular position of the right blinder of the quadrilateral
characteristic (see the Quadrilateral distance characteristic figures).
• PHS DIST Z1 QUAD LFT BLD: This setting defines the left blinder position of the quadrilateral characteristic along the
resistive axis of the impedance plane (see the Quadrilateral distance characteristic figures). The angular position of the
blinder is adjustable with the use of the PHS DIST Z1 QUAD LFT BLD RCA setting. This setting applies only to the quadri-
lateral characteristic and should be set with consideration to the maximum load current.
• PHS DIST Z1 QUAD LFT BLD RCA: This setting defines the angular position of the left blinder of the quadrilateral
characteristic (see the Quadrilateral distance characteristic figures).
• PHS DIST Z1 SUPV: The phase distance elements are supervised by the magnitude of the line-to-line current (fault
loop current used for the distance calculations). For convenience, 3 is accommodated by the pickup (that is, before
being used, the entered value of the threshold setting is multiplied by 3 ).
If the minimum fault current level is sufficient, the current supervision pickup should be set above maximum full load
current preventing maloperation under VT fuse fail conditions. This requirement may be difficult to meet for remote
faults at the end of zones 2 and above. If this is the case, the current supervision pickup would be set below the full
load current, but this may result in maloperation during fuse fail conditions.
• PHS DIST Z1 VOLT LEVEL: This setting is relevant for applications on series-compensated lines, or in general, if
series capacitors are located between the relaying point and a point where the zone shall not overreach. For plain
(non-compensated) lines, set to zero. Otherwise, the setting is entered in per unit of the phase VT bank configured
under the DISTANCE SOURCE. Effectively, this setting facilitates dynamic current-based reach reduction. In non-direc-
tional applications (PHS DIST Z1 DIR set to “Non-directional”), this setting applies only to the forward reach of the non-
directional zone. See chapters 8 and 9 for information on calculating this setting for series compensated lines.
• PHS DIST Z1 DELAY: This setting allows the user to delay operation of the distance elements and implement stepped
distance protection. The distance element timers for zones 2 and higher apply a short dropout delay to cope with faults
located close to the zone boundary when small oscillations in the voltages or currents could inadvertently reset the
timer. Zone 1 does not need any drop out delay since it is sealed-in by the presence of current.
• PHS DIST Z1 BLK: This setting enables the user to select a FlexLogic™ operand to block a given distance element.
VT fuse fail detection is one of the applications for this setting.

c) GROUND DISTANCE
PATH: SETTINGS GROUPED ELEMENTS SETTING GROUP 1(6) DISTANCE GROUND DISTANCE Z1(Z3)
Three zones of ground distance protection with a minimum 150 ms time delay are provided as backup protection for trans-
formers or adjacent lines.
The ground mho distance function uses a dynamic 100% memory-polarized mho characteristic with additional reactance,
directional, current, and phase selection supervising characteristics. The ground quadrilateral distance function is com-
posed of a reactance characteristic, right and left blinders, and 100% memory-polarized directional, overcurrent, and phase
selection supervising characteristics.
When set to non-directional, the mho function becomes an offset mho with the reverse reach controlled independently from
the forward reach, and all the directional characteristics removed. When set to non-directional, the quadrilateral function
applies a reactance line in the reverse direction instead of the directional comparators.
The reactance supervision for the mho function uses the zero-sequence current for polarization. The reactance line of the
quadrilateral function uses either zero-sequence or negative-sequence current as a polarizing quantity. The selection is
5 controlled by a user setting and depends on the degree of non-homogeneity of the zero-sequence and negative-sequence
equivalent networks.
The directional supervision uses memory voltage as polarizing quantity and both zero- and negative-sequence currents as
operating quantities.
The phase selection supervision restrains the ground elements during double-line-to-ground faults as they – by principles
of distance relaying – may be inaccurate in such conditions. Ground distance zones 1 and higher apply additional zero-
sequence directional supervision. See chapter 8 for additional details.
Each ground distance zone is configured individually through its own setting menu. All of the settings can be independently
modified for each of the zones except:
1. The SIGNAL SOURCE setting (common for both phase and ground elements for all zones as entered under the SETTINGS
GROUPED ELEMENTS SETTING GROUP 1(6) DISTANCE menu).
2. The MEMORY DURATION setting (common for both phase and ground elements for all zones as entered under the SET-
TINGS GROUPED ELEMENTS SETTING GROUP 1(6) DISTANCE menu).
The common distance settings noted at the start of this section must be properly chosen for correct operation of the ground
distance elements.
Although all ground distance zones can be used as either instantaneous elements (pickup [PKP] and dropout [DPO] Flex-
Logic™ signals) or time-delayed elements (operate [OP] FlexLogic™ signals), only zone 1 is intended for the instantaneous
under-reaching tripping mode.
Ensure that the PHASE VT SECONDARY VOLTAGE (see the SETTINGS SYSTEM SETUP AC INPUTS VOLTAGE
BANK menu) is set correctly to prevent improper operation of associated memory action.
WARNING
• GND DIST Z1 DIR: All ground distance zones are reversible. The forward direction is defined by the GND DIST Z1 RCA
setting and the reverse direction is shifted by 180° from that angle. The non-directional zone spans between the for-
ward reach impedance defined by the GND DIST Z1 REACH and GND DIST Z1 RCA settings, and the reverse reach imped-
ance defined by the GND DIST Z1 REV REACH and GND DIST Z1 REV REACH RCA settings.
• GND DIST Z1 SHAPE: This setting selects the shape of the ground distance characteristic between the mho and
quadrilateral characteristics. The selection is available on a per-zone basis.

tive to set this setting to zero if the compensation is not to be performed.
• GND DIST Z1 ZOM/Z1 ANG: This setting specifies the angle difference between the mutual zero-sequence imped-
ance between the lines and the positive-sequence impedance of the protected line.
• GND DIST Z1 REACH: This setting defines the reach of the zone for the forward and reverse applications. In non-
directional applications, this setting defines the forward reach of the zone. The reverse reach impedance in non-direc-

The reach impedance is entered in secondary ohms.
• GND DIST Z1 RCA: This setting specifies the characteristic angle (similar to the maximum torque angle in previous
technologies) of the ground distance characteristic for the forward and reverse applications. In the non-directional
applications this setting defines the forward reach of the zone. The reverse reach impedance in the non-directional
applications is set independently. This setting is independent from the GND DIST Z1 DIR RCA setting (the characteristic
angle of an extra directional supervising function).

• GND DIST Z1 REV REACH: This setting defines the reverse reach of the zone set to non-directional (GND DIST Z1 DIR
setting). The value must be entered in secondary ohms. This setting does not apply when the zone direction is set to
“Forward” or “Reverse”.
• GND DIST Z1 REV REACH RCA: This setting defines the angle of the reverse reach impedance if the zone is set to
non-directional (GND DIST Z1 DIR setting). This setting does not apply when the zone direction is set to “Forward” or
5 “Reverse”.
• GND DIST Z1 POL CURRENT: This setting applies only if the GND DIST Z1 SHAPE is set to “Quad” and controls the
polarizing current used by the reactance comparator of the quadrilateral characteristic. Either the zero-sequence or
negative-sequence current could be used. In general, a variety of system conditions must be examined to select an
optimum polarizing current. This setting becomes less relevant when the resistive coverage and zone reach are set
conservatively. Also, this setting is more relevant in lower voltage applications such as on distribution lines or cables,
as compared with high-voltage transmission lines. This setting applies to both the zone 1 and reverse reactance lines
if the zone is set to non-directional. Refer to chapters 8 and 9 for additional information.
• GND DIST Z1 NON-HOMOGEN ANG: This setting applies only if the GND DIST Z1 SHAPE is set to “Quad” and provides
a method to correct the angle of the polarizing current of the reactance comparator for non-homogeneity of the zero-
sequence or negative-sequence networks. In general, a variety of system conditions must be examined to select this
setting. In many applications this angle is used to reduce the reach at high resistances in order to avoid overreaching
under far-out reach settings and/or when the sequence networks are greatly non-homogeneous. This setting applies to
both the forward and reverse reactance lines if the zone is set to non-directional. Refer to chapters 8 and 9 for addi-
tional information.
• GND DIST Z1 COMP LIMIT: This setting shapes the operating characteristic. In particular, it enables a lens-shaped
characteristic of the mho function and a tent-shaped characteristic of the quadrilateral function reactance boundary. If
the mho shape is selected, the same limit angle applies to mho and supervising reactance comparators. In conjunction
with the mho shape selection, this setting improves loadability of the protected line. In conjunction with the quadrilat-
eral characteristic, this setting improves security for faults close to the reach point by adjusting the reactance boundary
into a tent-shape.
• GND DIST Z1 DIR RCA: Selects the characteristic angle (or ‘maximum torque angle’) of the directional supervising
function. If the mho shape is applied, the directional function is an extra supervising function, as the dynamic mho
characteristic itself is a directional one. In conjunction with the quadrilateral shape selection, this setting defines the
only directional function built into the ground distance element. The directional function uses memory voltage for polar-
ization.
• GND DIST Z1 DIR COMP LIMIT: This setting selects the comparator limit angle for the directional supervising function.
• GND DIST Z1 QUAD RGT BLD: This setting defines the right blinder position of the quadrilateral characteristic along
the resistive axis of the impedance plane (see the Quadrilateral distance characteristic figure). The angular position of
the blinder is adjustable with the use of the GND DIST Z1 QUAD RGT BLD RCA setting. This setting applies only to the
quadrilateral characteristic and should be set with consideration to the maximum load current and required resistive
coverage.
• GND DIST Z1 QUAD RGT BLD RCA: This setting defines the angular position of the right blinder of the quadrilateral
characteristic (see the Quadrilateral distance characteristic figure).
• GND DIST Z1 QUAD LFT BLD: This setting defines the left blinder position of the quadrilateral characteristic along the
resistive axis of the impedance plane (see the Quadrilateral distance characteristic figure). The angular position of the
blinder is adjustable with the use of the GND DIST Z1 QUAD LFT BLD RCA setting. This setting applies only to the quadri-
lateral characteristic and should be set with consideration to the maximum load current.
• GND DIST Z1 QUAD LFT BLD RCA: This setting defines the angular position of the left blinder of the quadrilateral
characteristic (see the Quadrilateral distance characteristic figure).
• GND DIST Z1 SUPV: The ground distance elements are supervised by the magnitude of the neutral (3I_0) current.
The current supervision pickup should be set less than the minimum 3I_0 current for the end of the zone fault, taking
into account the desired fault resistance coverage to prevent maloperation due to VT fuse failure. Settings less than
0.2 pu are not recommended and should be applied with caution. To enhance ground distance security against spuri-
ous neutral current during switch-off transients, three-phase faults, and phase-to-phase faults, a positive-sequence
current restraint of 5% is applied to the neutral current supervision magnitude. This setting should be at least three
times the CURRENT CUTOFF LEVEL setting specified in the PRODUCT SETUP DISPLAY PROPERTIES menu
• GND DIST Z1 VOLT LEVEL: This setting is relevant for applications on series-compensated lines, or in general, if
series capacitors are located between the relaying point and a point for which the zone shall not overreach. For plain
(non-compensated) lines, this setting shall be set to zero. Otherwise, the setting is entered in per unit of the VT bank
configured under the DISTANCE SOURCE. Effectively, this setting facilitates dynamic current-based reach reduction. In
non-directional applications (GND DIST Z1 DIR set to “Non-directional”), this setting applies only to the forward reach of
the non-directional zone. See chapters 8 and 9 for additional details and information on calculating this setting value
for applications on series compensated lines.

• GND DIST Z1 DELAY: This setting enables the user to delay operation of the distance elements and implement a

located close to the boundary of the zone when small oscillations in the voltages or currents could inadvertently reset
the timer.

PATH: SETTINGS GROUPED ELEMENTS SETTING GROUP 1(6) POWER SWING DETECT
The power swing detect element provides both power swing blocking and out-of-step tripping functions. The element mea-
sures the positive-sequence apparent impedance and traces its locus with respect to either two or three user-selectable
operating characteristic boundaries. Upon detecting appropriate timing relations, the blocking and tripping indications are
given through FlexLogic™ operands. The element incorporates an adaptive disturbance detector. This function does not
trigger on power swings, but is capable of detecting faster disturbances – faults in particular – that may occur during power
swings. Operation of this dedicated disturbance detector is signaled via the POWER SWING 50DD operand.
The power swing detect element asserts two outputs intended for blocking selected protection elements on power swings:
POWER SWING BLOCK is a traditional signal that is safely asserted for the entire duration of the power swing, and POWER
SWING UN/BLOCK is established in the same way, but resets when an extra disturbance is detected during the power swing.
The POWER SWING UN/BLOCK operand may be used for blocking selected protection elements if the intent is to respond to
faults during power swing conditions.
Different protection elements respond differently to power swings. If tripping is required for faults during power swing condi-
tions, some elements may be blocked permanently (using the POWER SWING BLOCK operand), and others may be blocked
and dynamically unblocked upon fault detection (using the POWER SWING UN/BLOCK operand).
The operating characteristic and logic figures should be viewed along with the following discussion to develop an under-
standing of the operation of the element.
The power swing detect element operates in three-step or two-step mode:
• Three-step operation: The power swing blocking sequence essentially times the passage of the locus of the positive-
sequence impedance between the outer and the middle characteristic boundaries. If the locus enters the outer charac-
teristic (indicated by the POWER SWING OUTER FlexLogic™ operand) but stays outside the middle characteristic (indi-
cated by the POWER SWING MIDDLE FlexLogic™ operand) for an interval longer than POWER SWING PICKUP DELAY 1,
the power swing blocking signal (POWER SWING BLOCK FlexLogic™ operand) is established and sealed-in. The block-
ing signal resets when the locus leaves the outer characteristic, but not sooner than the POWER SWING RESET DELAY 1
time.
• Two-step operation: If the two-step mode is selected, the sequence is identical, but it is the outer and inner character-
istics that are used to time the power swing locus.
The out-of-step tripping feature operates as follows for three-step and two-step power swing detection modes:
• Three-step operation: The out-of-step trip sequence identifies unstable power swings by determining if the imped-
ance locus spends a finite time between the outer and middle characteristics and then a finite time between the middle
and inner characteristics. The first step is similar to the power swing blocking sequence. After timer POWER SWING
PICKUP DELAY 1 times out, latch 1 is set as long as the impedance stays within the outer characteristic.
If afterwards, at any time (given the impedance stays within the outer characteristic), the locus enters the middle char-
acteristic but stays outside the inner characteristic for a period of time defined as POWER SWING PICKUP DELAY 2, latch
2 is set as long as the impedance stays inside the outer characteristic. If afterwards, at any time (given the impedance
stays within the outer characteristic), the locus enters the inner characteristic and stays there for a period of time
defined as POWER SWING PICKUP DELAY 3, latch 2 is set as long as the impedance stays inside the outer characteristic;
the element is now ready to trip.
If the "Early" trip mode is selected, the POWER SWING TRIP operand is set immediately and sealed-in for the interval 5
set by the POWER SWING SEAL-IN DELAY. If the "Delayed" trip mode is selected, the element waits until the impedance
locus leaves the inner characteristic, then times out the POWER SWING PICKUP DELAY 2 and sets Latch 4; the element is
now ready to trip. The trip operand is set later, when the impedance locus leaves the outer characteristic.
• Two-step operation: The two-step mode of operation is similar to the three-step mode with two exceptions. First, the
initial stage monitors the time spent by the impedance locus between the outer and inner characteristics. Second, the
stage involving the POWER SWING PICKUP DELAY 2 timer is bypassed. It is up to the user to integrate the blocking
(POWER SWING BLOCK) and tripping (POWER SWING TRIP) FlexLogic™ operands with other protection functions and
output contacts in order to make this element fully operational.
The element can be set to use either lens (mho) or rectangular (quadrilateral) characteristics as illustrated below. When set
to “Mho”, the element applies the right and left blinders as well. If the blinders are not required, their settings should be set
high enough to effectively disable the blinders.

Figure 5–79: POWER SWING DETECT QUADRILATERAL OPERATING CHARACTERISTICS
The FlexLogic™ output operands for the power swing detect element are described below:
• The POWER SWING OUTER, POWER SWING MIDDLE, POWER SWING INNER, POWER SWING TMR2 PKP, POWER SWING
TMR3 PKP, and POWER SWING TMR4 PKP FlexLogic™ operands are auxiliary operands that could be used to facilitate
testing and special applications.
• The POWER SWING BLOCK FlexLogic™ operand shall be used to block selected protection elements such as distance
functions.
• The POWER SWING UN/BLOCK FlexLogic™ operand shall be used to block those protection elements that are intended
to be blocked under power swings, but subsequently unblocked should a fault occur after the power swing blocking
condition has been established.
• The POWER SWING 50DD FlexLogic™ operand indicates that an adaptive disturbance detector integrated with the ele-
ment has picked up. This operand will trigger on faults occurring during power swing conditions. This includes both
three-phase and single-pole-open conditions.
• The POWER SWING INCOMING FlexLogic™ operand indicates an unstable power swing with an incoming locus (the
locus enters the inner characteristic).
• The POWER SWING OUTGOING FlexLogic™ operand indicates an unstable power swing with an outgoing locus (the
locus leaving the outer characteristic). This operand can be used to count unstable swings and take certain action only
after pre-defined number of unstable power swings.
• The POWER SWING TRIP FlexLogic™ operand is a trip command.
The settings for the power swing detect element are described below:
• POWER SWING FUNCTION: This setting enables and disables the entire power swing detection element. The setting
applies to both power swing blocking and out-of-step tripping functions.
• POWER SWING SOURCE: The source setting identifies the signal source for both blocking and tripping functions.
• POWER SWING SHAPE: This setting selects the shapes (either “Mho” or “Quad”) of the outer, middle and, inner char-
acteristics of the power swing detect element. The operating principle is not affected. The “Mho” characteristics use the
left and right blinders.
• POWER SWING MODE: This setting selects between the two-step and three-step operating modes and applies to
both power swing blocking and out-of-step tripping functions. The three-step mode applies if there is enough space
between the maximum load impedances and distance characteristics of the relay that all three (outer, middle, and
inner) characteristics can be placed between the load and the distance characteristics. Whether the spans between
the outer and middle as well as the middle and inner characteristics are sufficient should be determined by analysis of
the fastest power swings expected in correlation with settings of the power swing timers.
The two-step mode uses only the outer and inner characteristics for both blocking and tripping functions. This leaves
more space in heavily loaded systems to place two power swing characteristics between the distance characteristics
and the maximum load, but allows for only one determination of the impedance trajectory.
• POWER SWING SUPV: A common overcurrent pickup level supervises all three power swing characteristics. The
supervision responds to the positive sequence current.
• POWER SWING FWD REACH: This setting specifies the forward reach of all three mho characteristics and the inner
quadrilateral characteristic. For a simple system consisting of a line and two equivalent sources, this reach should be
higher than the sum of the line and remote source positive-sequence impedances. Detailed transient stability studies
may be needed for complex systems in order to determine this setting. The angle of this reach impedance is specified
by the POWER SWING FWD RCA setting.
• POWER SWING QUAD FWD REACH MID: This setting specifies the forward reach of the middle quadrilateral charac-
teristic. The angle of this reach impedance is specified by the POWER SWING FWD RCA setting. The setting is not used if
the shape setting is “Mho”.
• POWER SWING QUAD FWD REACH OUT: This setting specifies the forward reach of the outer quadrilateral charac-
teristic. The angle of this reach impedance is specified by the POWER SWING FWD RCA setting. The setting is not used if
the shape setting is “Mho”.
• POWER SWING FWD RCA: This setting specifies the angle of the forward reach impedance for the mho characteris-
5 tics, angles of all the blinders, and both forward and reverse reach impedances of the quadrilateral characteristics.
• POWER SWING REV REACH: This setting specifies the reverse reach of all three mho characteristics and the inner
quadrilateral characteristic. For a simple system of a line and two equivalent sources, this reach should be higher than
the positive-sequence impedance of the local source. Detailed transient stability studies may be needed for complex
systems to determine this setting. The angle of this reach impedance is specified by the POWER SWING REV RCA setting
for “Mho”, and the POWER SWING FWD RCA setting for “Quad”.
• POWER SWING QUAD REV REACH MID: This setting specifies the reverse reach of the middle quadrilateral charac-
teristic. The angle of this reach impedance is specified by the POWER SWING FWD RCA setting. The setting is not used if
the shape setting is “Mho”.
• POWER SWING QUAD REV REACH OUT: This setting specifies the reverse reach of the outer quadrilateral charac-
teristic. The angle of this reach impedance is specified by the POWER SWING FWD RCA setting. The setting is not used if
the shape setting is “Mho”.
• POWER SWING REV RCA: This setting specifies the angle of the reverse reach impedance for the mho characteris-
tics. This setting applies to mho shapes only.
• POWER SWING OUTER LIMIT ANGLE: This setting defines the outer power swing characteristic. The convention
depicted in the Power swing detect characteristic diagram should be observed: values greater than 90° result in an
apple-shaped characteristic; values less than 90° result in a lens shaped characteristic. This angle must be selected in
consideration of the maximum expected load. If the maximum load angle is known, the outer limit angle should be
coordinated with a 20° security margin. Detailed studies may be needed for complex systems to determine this setting.
This setting applies to mho shapes only.
• POWER SWING MIDDLE LIMIT ANGLE: This setting defines the middle power swing detect characteristic. It is rele-
vant only for the 3-step mode. A typical value would be close to the average of the outer and inner limit angles. This
setting applies to mho shapes only.
• POWER SWING INNER LIMIT ANGLE: This setting defines the inner power swing detect characteristic. The inner
characteristic is used by the out-of-step tripping function: beyond the inner characteristic out-of-step trip action is defi-
nite (the actual trip may be delayed as per the TRIP MODE setting). Therefore, this angle must be selected in consider-
ation to the power swing angle beyond which the system becomes unstable and cannot recover.
The inner characteristic is also used by the power swing blocking function in the two-step mode. In this case, set this
angle large enough so that the characteristics of the distance elements are safely enclosed by the inner characteristic.
This setting applies to mho shapes only.
• POWER SWING OUTER, MIDDLE, and INNER RGT BLD: These settings specify the resistive reach of the right
blinder. The blinder applies to both “Mho” and “Quad” characteristics. Set these value high if no blinder is required for
the “Mho” characteristic.
• POWER SWING OUTER, MIDDLE, and INNER LFT BLD: These settings specify the resistive reach of the left blinder.
Enter a positive value; the relay automatically uses a negative value. The blinder applies to both “Mho” and “Quad”
characteristics. Set this value high if no blinder is required for the “Mho” characteristic.
• POWER SWING PICKUP DELAY 1: All the coordinating timers are related to each other and should be set to detect
the fastest expected power swing and produce out-of-step tripping in a secure manner. The timers should be set in
consideration to the power swing detect characteristics, mode of power swing detect operation and mode of out-of-
step tripping. This timer defines the interval that the impedance locus must spend between the outer and inner charac-
teristics (two-step operating mode), or between the outer and middle characteristics (three-step operating mode)
before the power swing blocking signal is established. This time delay must be set shorter than the time required for
the impedance locus to travel between the two selected characteristics during the fastest expected power swing. This
setting is relevant for both power swing blocking and out-of-step tripping.
• POWER SWING RESET DELAY 1: This setting defines the dropout delay for the power swing blocking signal. Detec-
tion of a condition requiring a block output sets latch 1 after PICKUP DELAY 1 time. When the impedance locus leaves
the outer characteristic, timer POWER SWING RESET DELAY 1 is started. When the timer times-out the latch is reset. This
setting should be selected to give extra security for the power swing blocking action.
• POWER SWING PICKUP DELAY 2: Controls the out-of-step tripping function in the three-step mode only. This timer
defines the interval the impedance locus must spend between the middle and inner characteristics before the second
step of the out-of-step tripping sequence is completed. This time delay must be set shorter than the time required for
the impedance locus to travel between the two characteristics during the fastest expected power swing. 5
• POWER SWING PICKUP DELAY 3: Controls the out-of-step tripping function only. It defines the interval the imped-
ance locus must spend within the inner characteristic before the last step of the out-of-step tripping sequence is com-
pleted and the element is armed to trip. The actual moment of tripping is controlled by the TRIP MODE setting. This time
delay is provided for extra security before the out-of-step trip action is executed.
• POWER SWING PICKUP DELAY 4: Controls the out-of-step tripping function in “Delayed” trip mode only. This timer
defines the interval the impedance locus must spend outside the inner characteristic but within the outer characteristic
before the element is armed for the delayed trip. The delayed trip occurs when the impedance leaves the outer charac-
teristic. This time delay is provided for extra security and should be set considering the fastest expected power swing.
• POWER SWING SEAL-IN DELAY: The out-of-step trip FlexLogic™ operand (POWER SWING TRIP) is sealed-in for the
specified period of time. The sealing-in is crucial in the delayed trip mode, as the original trip signal is a very short
pulse occurring when the impedance locus leaves the outer characteristic after the out-of-step sequence is completed.
• POWER SWING TRIP MODE: Selection of the “Early” trip mode results in an instantaneous trip after the last step in
the out-of-step tripping sequence is completed. The early trip mode will stress the circuit breakers as the currents at
that moment are high (the electromotive forces of the two equivalent systems are approximately 180° apart). Selection
of the “Delayed” trip mode results in a trip at the moment when the impedance locus leaves the outer characteristic.
delayed trip mode will relax the operating conditions for the breakers as the currents at that moment are low. The
selection should be made considering the capability of the breakers in the system.
• POWER SWING BLK: This setting specifies the FlexLogic™ operand used for blocking the out-of-step function only.
The power swing blocking function is operational all the time as long as the element is enabled. The blocking signal
resets the output POWER SWING TRIP operand but does not stop the out-of-step tripping sequence.

The calculation of differential (Id) and restraint (Ir) currents for the purposes of the percent differential element is described
by the following block diagram, where “” has as its output the vector sum of inputs, and “max” has as its output the input of
maximum magnitude; these calculations are performed for each phase.
The differential current is calculated as a vector sum of currents from all windings after magnitude and angle compensation.
The restraint current is calculated as a maximum of the same internally compensated currents.
The element operates if Id > PKP and Id > Ir, where PKP represents a differential pickup setting and K is a restraint factor.

• PERCENT DIFFERENTIAL PICKUP: This setting defines the minimum differential current required for operation. It is
chosen, based on the amount of differential current that might be seen under normal operating conditions. Two factors
may create differential current during the normal transformer operation: errors due to CT inaccuracies and current vari-
ation due to onload tap changer operation.
A setting of 0.1 to 0.3 is generally recommended (the factory default is 0.1 pu).
• PERCENT DIFFERENTIAL SLOPE 1: This setting defines the differential restraint during normal operating conditions
to assure sensitivity to internal faults. The setting must be high enough, however, to cope with CT saturation errors dur-
ing saturation under small current magnitudes but significant and long lasting DC components (such as during distant
external faults in vicinity of generators).
• PERCENT DIFFERENTIAL BREAK 1 and PERCENT DIFFERENTIAL BREAK 2: The settings for break 1 and break
2 depend very much on the capability of CTs to correctly transform primary into secondary currents during external
faults. Break 2 should be set below the fault current that is most likely to saturate some CTs due to an AC component
alone. Break 1 should be set below a current that would cause CT saturation due to DC components and/or residual
magnetism. The latter may be as high as 80% of the nominal flux, effectively reducing the CT capabilities by the factor
of 5.
• PERCENT DIFFERENTIAL SLOPE 2: The slope 2 setting ensures stability during heavy through fault conditions,
where CT saturation results in high differential current. Slope 2 should be set high to cater for the worst case where
one set of CTs saturates but the other set doesn't. In such a case the ratio of the differential current to restraint current
can be as high as 95 to 98%.
• INRUSH INHIBIT FUNCTION: This setting provides a choice for 2nd harmonic differential protection blocking during
magnetizing inrush conditions. Two choices are available: “Adapt. 2nd” – adaptive 2nd harmonic, and “Trad. 2nd” – tra-
ditional 2nd harmonic blocking. The adaptive 2nd harmonic restraint responds to magnitudes and phase angles of the
2nd harmonic and the fundamental frequency component. The traditional 2nd harmonic restraint responds to the ratio
of magnitudes of the 2nd harmonic and fundamental frequency components. If low second harmonic ratios during
magnetizing inrush conditions are not expected, the relay should be set to traditional way of restraining. 5
• INRUSH INHIBIT MODE: This setting specifies mode of blocking on magnetizing inrush conditions. Modern transform-
ers may produce small 2nd harmonic ratios during inrush conditions. This may result undesired tripping of the pro-
tected transformer. Reducing the 2nd harmonic inhibit threshold may jeopardize dependability and speed of protection.
The 2nd harmonic ratio, if low, causes problems in one phase only. This may be utilized as a mean to ensure security
by applying cross-phase blocking rather than lowering the inrush inhibit threshold.
If set to “Per phase”, the relay performs inrush inhibit individually in each phase. If used on modern transformers, this
setting should be combined with adaptive 2nd harmonic function.
If set to “2-out-of-3”, the relay checks 2nd harmonic level in all three phases individually. If any two phases establish a
blocking condition, the remaining phase is restrained automatically.
If set to “Average”, the relay first calculates the average 2nd harmonic ratio, then applies the inrush threshold to the
calculated average. This mode works only in conjunction with the traditional 2nd harmonic function.
• INRUSH INHIBIT LEVEL: This setting specifies the level of 2nd harmonic component in the transformer magnetizing
inrush current above which the percent differential element will be inhibited from operating. The value of the INRUSH
INHIBIT MODE setting must be taken into account when programming this value. The INRUSH INHIBIT LEVEL is typically
set to 20%.
• OVEREXCITATION INHIBIT MODE: An overexcitation condition resulting from an increased volts/hertz ratio poses a
danger to the protected transformer, hence the volts/hertz protection. A given transformer can, however, tolerate an
overfluxing condition for a limited time, as the danger is associated with thermal processes in the core. Instantaneous
tripping of the transformer from the differential protection is not desirable. The relay uses a traditional 5th harmonic
ratio for inhibiting its differential function during overexcitation conditions.
• OVEREXCITATION INHIBIT LEVEL: This setting is provided to block the differential protection during overexcitation.
When the 5th harmonic level exceeds the specified setting (5th harmonic ratio) the differential element is blocked. The
overexcitation inhibit works on a per-phase basis.
The relay produces three FlexLogic™ operands that may be used for testing or for special applications such as building
custom logic (1-out-of-3) or supervising some protection functions (ground time overcurrent, for example) from the 2nd har-
monic inhibit.

5 The phase current elements can be used for tripping, alarming, or other functions. The actual number of elements depends
on the number of current banks.
A time dial multiplier setting allows selection of a multiple of the base curve shape (where the time dial multiplier = 1) with
the curve shape (CURVE) setting. Unlike the electromechanical time dial equivalent, operate times are directly proportional
to the time multiplier (TD MULTIPLIER) setting value. For example, all times for a multiplier of 10 are 10 times the multiplier 1
or base curve values. Setting the multiplier to zero results in an instantaneous response to all current levels above pickup.
Time overcurrent time calculations are made with an internal energy capacity memory variable. When this variable indi-
cates that the energy capacity has reached 100%, a time overcurrent element will operate. If less than 100% energy capac-
ity is accumulated in this variable and the current falls below the dropout threshold of 97 to 98% of the pickup value, the
variable must be reduced. Two methods of this resetting operation are available: “Instantaneous” and “Timed”. The “Instan-
taneous” selection is intended for applications with other relays, such as most static relays, which set the energy capacity
directly to zero when the current falls below the reset threshold. The “Timed” selection can be used where the relay must
coordinate with electromechanical relays.
IEEE CURVES:
The IEEE time overcurrent curve shapes conform to industry standards and the IEEE C37.112-1996 curve classifications
for extremely, very, and moderately inverse. The IEEE curves are derived from the formulae:

The phase time overcurrent element can provide a desired time-delay operating characteristic versus the applied current or
be used as a simple definite time element. The phase current input quantities may be programmed as fundamental phasor
magnitude or total waveform RMS magnitude as required by the application.
Two methods of resetting operation are available: “Timed” and “Instantaneous” (refer to the Inverse Time overcurrent
curves characteristic sub-section earlier for details on curve setup, trip times, and reset operation). When the element is
blocked, the time accumulator will reset according to the reset characteristic. For example, if the element reset characteris-
tic is set to “Instantaneous” and the element is blocked, the time accumulator will be cleared immediately.
The PHASE TOC1 PICKUP setting can be dynamically reduced by a voltage restraint feature (when enabled). This is accom-
plished via the multipliers (Mvr) corresponding to the phase-phase voltages of the voltage restraint characteristic curve (see
the figure below); the pickup level is calculated as ‘Mvr’ times the PHASE TOC1 PICKUP setting. If the voltage restraint feature
is disabled, the pickup level always remains at the setting value.

This element is intended to apply a block signal to an overcurrent element to prevent an operation when current is flowing
in a particular direction. The direction of current flow is determined by measuring the phase angle between the current from
the phase CTs and the line-line voltage from the VTs, based on the 90° or quadrature connection. If there is a requirement
to supervise overcurrent elements for flows in opposite directions, such as can happen through a bus-tie breaker, two
phase directional elements should be programmed with opposite element characteristic angle (ECA) settings.
To increase security for three phase faults very close to the VTs used to measure the polarizing voltage, a voltage memory
feature is incorporated. This feature stores the polarizing voltage the moment before the voltage collapses, and uses it to
determine direction. The voltage memory remains valid for one second after the voltage has collapsed.
The main component of the phase directional element is the phase angle comparator with two inputs: the operating signal
(phase current) and the polarizing signal (the line voltage, shifted in the leading direction by the characteristic angle, ECA).
The following table shows the operating and polarizing signals used for phase directional control:

B angle of IB angle of VCA (1ECA) angle of VAC 1ECA)
C angle of IC angle of VAB (1ECA) angle of VBA (1ECA)
MODE OF OPERATION:
• When the function is “Disabled”, or the operating current is below 5% CT nominal, the element output is “0”.
• When the function is “Enabled”, the operating current is above 5% CT nominal, and the polarizing voltage is above
the PRODUCT SETUP DISPLAY PROPERTIES VOLTAGE CUT-OFF LEVEL value, the element output is dependent on
the phase angle between the operating and polarizing signals:
5 – The element output is logic “0” when the operating current is within polarizing voltage ±90°.
– For all other angles, the element output is logic “1”.
• Once the voltage memory has expired, the phase overcurrent elements under directional control can be set to block or
trip on overcurrent as follows:
– When BLOCK WHEN V MEM EXP is set to “Yes”, the directional element will block the operation of any phase
overcurrent element under directional control when voltage memory expires.
– When BLOCK WHEN V MEM EXP is set to “No”, the directional element allows tripping of phase overcurrent elements
under directional control when voltage memory expires.
In all cases, directional blocking will be permitted to resume when the polarizing voltage becomes greater than the ‘polariz-
ing voltage threshold’.
SETTINGS:
• PHASE DIR 1 SIGNAL SOURCE: This setting is used to select the source for the operating and polarizing signals.
The operating current for the phase directional element is the phase current for the selected current source. The polar-
izing voltage is the line voltage from the phase VTs, based on the 90° or ‘quadrature’ connection and shifted in the
leading direction by the element characteristic angle (ECA).
• PHASE DIR 1 ECA: This setting is used to select the element characteristic angle, i.e. the angle by which the polariz-
ing voltage is shifted in the leading direction to achieve dependable operation. In the design of the UR-series elements,
a block is applied to an element by asserting logic 1 at the blocking input. This element should be programmed via the
ECA setting so that the output is logic 1 for current in the non-tripping direction.
• PHASE DIR 1 POL V THRESHOLD: This setting is used to establish the minimum level of voltage for which the phase
angle measurement is reliable. The setting is based on VT accuracy. The default value is “0.700 pu”.
• PHASE DIR 1 BLOCK WHEN V MEM EXP: This setting is used to select the required operation upon expiration of
voltage memory. When set to "Yes", the directional element blocks the operation of any phase overcurrent element
under directional control, when voltage memory expires; when set to "No", the directional element allows tripping of
phase overcurrent elements under directional control.
The phase directional element responds to the forward load current. In the case of a following reverse fault,
the element needs some time – in the order of 8 ms – to establish a blocking signal. Some protection ele-
NOTE
ments such as instantaneous overcurrent may respond to reverse faults before the blocking signal is
established. Therefore, a coordination time of at least 10 ms must be added to all the instantaneous protec-
tion elements under the supervision of the phase directional element. If current reversal is of a concern, a
longer delay – in the order of 20 ms – may be needed.

5 The T60 relay contains six neutral time overcurrent elements, eight neutral instantaneous overcurrent elements, and one
neutral directional overcurrent element. For additional information on the neutral time overcurrent curves, refer to Inverse
TOC Characteristics on page 5–180.
The neutral time overcurrent element can provide a desired time-delay operating characteristic versus the applied current
or be used as a simple definite time element. The neutral current input value is a quantity calculated as 3Io from the phase
currents and may be programmed as fundamental phasor magnitude or total waveform RMS magnitude as required by the
application.
Two methods of resetting operation are available: “Timed” and “Instantaneous” (refer to the Inverse time overcurrent curve
characteristics section for details on curve setup, trip times and reset operation). When the element is blocked, the time
accumulator will reset according to the reset characteristic. For example, if the element reset characteristic is set to “Instan-
taneous” and the element is blocked, the time accumulator will be cleared immediately.

The neutral instantaneous overcurrent element may be used as an instantaneous function with no intentional delay or as a
5 definite time function. The element essentially responds to the magnitude of a neutral current fundamental frequency pha-
sor calculated from the phase currents. A positive-sequence restraint is applied for better performance. A small portion
(6.25%) of the positive-sequence current magnitude is subtracted from the zero-sequence current magnitude when forming
the operating quantity of the element as follows:
I op = 3 I_0 – K I_1 where K = 1 16 (EQ 5.37)
The positive-sequence restraint allows for more sensitive settings by counterbalancing spurious zero-sequence currents
resulting from:
• System unbalances under heavy load conditions
• Transformation errors of current transformers (CTs) during double-line and three-phase faults.
• Switch-off transients during double-line and three-phase faults.
The positive-sequence restraint must be considered when testing for pickup accuracy and response time (multiple of
pickup). The operating quantity depends on how test currents are injected into the relay (single-phase injection:
I op = 0.9375 I injected ; three-phase pure zero-sequence injection: I op = 3 I injected ).
SETTING
Off=0
SETTING
The neutral directional overcurrent element provides both forward and reverse fault direction indications the NEUTRAL DIR
OC1 FWD and NEUTRAL DIR OC1 REV operands, respectively. The output operand is asserted if the magnitude of the oper-
ating current is above a pickup level (overcurrent unit) and the fault direction is seen as forward or reverse, respectively
(directional unit).
The overcurrent unit responds to the magnitude of a fundamental frequency phasor of the either the neutral current calcu-
lated from the phase currents or the ground current. There are separate pickup settings for the forward-looking and
reverse-looking functions. If set to use the calculated 3I_0, the element applies a positive-sequence restraint for better per-
formance: a small user-programmable portion of the positive-sequence current magnitude is subtracted from the zero-
sequence current magnitude when forming the operating quantity.
I op = 3 I_0 – K I_1 (EQ 5.38)
The positive-sequence restraint allows for more sensitive settings by counterbalancing spurious zero-sequence currents
resulting from:
• System unbalances under heavy load conditions.
• Transformation errors of current transformers (CTs) during double-line and three-phase faults.
• Switch-off transients during double-line and three-phase faults.
The positive-sequence restraint must be considered when testing for pickup accuracy and response time (multiple of
pickup). The operating quantity depends on the way the test currents are injected into the relay (single-phase injection:
Iop = (1 – K) Iinjected ; three-phase pure zero-sequence injection: Iop = 3 Iinjected).
The positive-sequence restraint is removed for low currents. If the positive-sequence current is below 0.8 pu, the restraint is
removed by changing the constant K to zero. This facilitates better response to high-resistance faults when the unbalance
is very small and there is no danger of excessive CT errors as the current is low.
The directional unit uses the zero-sequence current (I_0) or ground current (IG) for fault direction discrimination and may
be programmed to use either zero-sequence voltage (“Calculated V0” or “Measured VX”), ground current (IG), or both for
polarizing. The following tables define the neutral directional overcurrent element.

ECA = element characteristic angle and IG = ground current
When NEUTRAL DIR OC1 POL VOLT is set to “Measured VX”, one-third of this voltage is used in place of V_0. The following
figure explains the usage of the voltage polarized directional unit of the element.
The figure below shows the voltage-polarized phase angle comparator characteristics for a phase A to ground fault, with:
• ECA = 90° (element characteristic angle = centerline of operating characteristic)
• FWD LA = 80° (forward limit angle = the ± angular limit with the ECA for operation)
• REV LA = 80° (reverse limit angle = the ± angular limit with the ECA for operation)
The above bias should be taken into account when using the neutral directional overcurrent element to directionalize other
protection elements.

For a choice of current polarizing, it is recommended that the polarizing signal be analyzed to ensure that a known
direction is maintained irrespective of the fault location. For example, if using an autotransformer neutral current
as a polarizing source, it should be ensured that a reversal of the ground current does not occur for a high-side
fault. The low-side system impedance should be assumed minimal when checking for this condition. A similar sit-
uation arises for a wye/delta/wye transformer, where current in one transformer winding neutral may reverse when
faults on both sides of the transformer are considered.
– If “Dual” polarizing is selected, the element performs both directional comparisons as described above. A given
direction is confirmed if either voltage or current comparators indicate so. If a conflicting (simultaneous forward
and reverse) indication occurs, the forward direction overrides the reverse direction.
• NEUTRAL DIR OC1 POL VOLT: Selects the polarizing voltage used by the directional unit when "Voltage" or "Dual"
polarizing mode is set. The polarizing voltage can be programmed to be either the zero-sequence voltage calculated
from the phase voltages ("Calculated V0") or supplied externally as an auxiliary voltage ("Measured VX").
• NEUTRAL DIR OC1 OP CURR: This setting indicates whether the 3I_0 current calculated from the phase currents, or
the ground current shall be used by this protection. This setting acts as a switch between the neutral and ground
modes of operation (67N and 67G). If set to “Calculated 3I0” the element uses the phase currents and applies the pos-
itive-sequence restraint; if set to “Measured IG” the element uses ground current supplied to the ground CT of the CT
bank configured as NEUTRAL DIR OC1 SOURCE. If this setting is “Measured IG”, then the NEUTRAL DIR OC1 POLARIZING
setting must be “Voltage”, as it is not possible to use the ground current as an operating and polarizing signal simulta-
neously.
• NEUTRAL DIR OC1 POS-SEQ RESTRAINT: This setting controls the amount of the positive-sequence restraint. Set
to 0.063 for backward compatibility with firmware revision 3.40 and older. Set to zero to remove the restraint. Set
higher if large system unbalances or poor CT performance are expected.
• NEUTRAL DIR OC1 OFFSET: This setting specifies the offset impedance used by this protection. The primary appli-
cation for the offset impedance is to guarantee correct identification of fault direction on series compensated lines. In
regular applications, the offset impedance ensures proper operation even if the zero-sequence voltage at the relaying
point is very small. If this is the intent, the offset impedance shall not be larger than the zero-sequence impedance of
the protected circuit. Practically, it shall be several times smaller. The offset impedance shall be entered in secondary
ohms.
• NEUTRAL DIR OC1 FWD ECA: This setting defines the characteristic angle (ECA) for the forward direction in the
"Voltage" polarizing mode. The "Current" polarizing mode uses a fixed ECA of 0°. The ECA in the reverse direction is
the angle set for the forward direction shifted by 180°.
• NEUTRAL DIR OC1 FWD LIMIT ANGLE: This setting defines a symmetrical (in both directions from the ECA) limit
angle for the forward direction.
• NEUTRAL DIR OC1 FWD PICKUP: This setting defines the pickup level for the overcurrent unit of the element in the
forward direction. When selecting this setting it must be kept in mind that the design uses a ‘positive-sequence

NEUTRAL DIR OC1 REV LIMIT ANGLE: This setting defines a symmetrical (in both directions from the ECA) limit
angle for the reverse direction.

The T60 relay contains six Ground Time Overcurrent elements, eight Ground Instantaneous Overcurrent elements, and
four Restricted Ground Fault elements. For additional information on the Ground Time Overcurrent curves, refer to Inverse
TOC Characteristics on page 5–180.
This element can provide a desired time-delay operating characteristic versus the applied current or be used as a simple
definite time element. The ground current input value is the quantity measured by the ground input CT and is the funda-
mental phasor or RMS magnitude. Two methods of resetting operation are available: “Timed” and “Instantaneous” (refer to
the Inverse time overcurrent curve characteristics section for details). When the element is blocked, the time accumulator
will reset according to the reset characteristic. For example, if the element reset characteristic is set to “Instantaneous” and
the element is blocked, the time accumulator will be cleared immediately.
These elements measure the current that is connected to the ground channel of a CT/VT module. The conversion
range of a standard channel is from 0.02 to 46 times the CT rating.
NOTE
This channel may be also equipped with a sensitive input. The conversion range of a sensitive channel is from
0.002 to 4.6 times the CT rating.

The relay automatically matches the CT ratios between the phase and ground CTs by re-scaling the ground CT to the
phase CT level. The restraining signal ensures stability of protection during CT saturation conditions and is produced as a
maximum value between three components related to zero, negative, and positive-sequence currents of the three phase
CTs as follows:
Irest = max IR0 IR1 IR2 (EQ 5.40)
The zero-sequence component of the restraining signal (IR0) is meant to provide maximum restraint during external ground
faults, and therefore is calculated as a vectorial difference of the ground and neutral currents:
The equation above brings an advantage of generating the restraining signal of twice the external ground fault current,
while reducing the restraint below the internal ground fault current. The negative-sequence component of the restraining
signal (IR2) is meant to provide maximum restraint during external phase-to-phase faults and is calculated as follows:
IR2 = I_2 or IR2 = 3 I_2 (EQ 5.42)
The multiplier of 1 is used by the relay for first two cycles following complete de-energization of the winding (all three phase
currents below 5% of nominal for at least five cycles). The multiplier of 3 is used during normal operation; that is, two cycles
after the winding has been energized. The lower multiplier is used to ensure better sensitivity when energizing a faulty
winding.
The positive-sequence component of the restraining signal (IR1) is meant to provide restraint during symmetrical condi-
tions, either symmetrical faults or load, and is calculated according to the following algorithm:
1 If I_1 1.5 pu of phase CT, then
2 If I_1 I_0 , then IR1 = 3 I_1 – I_0
3 else IR1 = 0
4 else IR1 = I_1 8
Under load-level currents (below 150% of nominal), the positive-sequence restraint is set to 1/8th of the positive-sequence
current (line 4). This is to ensure maximum sensitivity during low-current faults under full load conditions. Under fault-level
currents (above 150% of nominal), the positive-sequence restraint is removed if the zero-sequence component is greater
than the positive-sequence (line 3), or set at the net difference of the two (line 2).
The raw restraining signal (Irest) is further post-filtered for better performance during external faults with heavy CT satura-
tion and for better switch-off transient control:
Igr k = max Irest k Igr k – 1 (EQ 5.43) 5
where k represents a present sample, k – 1 represents the previous sample, and is a factory constant ( 1). The equa-
tion above introduces a decaying memory to the restraining signal. Should the raw restraining signal (Irest) disappear or
drop significantly, such as when an external fault gets cleared or a CT saturates heavily, the actual restraining signal (Igr(k))
will not reduce instantly but will keep decaying decreasing its value by 50% each 15.5 power system cycles.
Having the differential and restraining signals developed, the element applies a single slope differential characteristic with a
minimum pickup as shown in the logic diagram below.

The following examples explain how the restraining signal is created for maximum sensitivity and security. These examples
clarify the operating principle and provide guidance for testing of the element.
EXAMPLE 1: EXTERNAL SINGLE-LINE-TO-GROUND FAULT

PATH: SETTINGS GROUPED ELEMENTS SETTING GROUP 1(6) BREAKER FAILURE BREAKER FAILURE 1(4)
In general, a breaker failure scheme determines that a breaker signaled to trip has not cleared a fault within a definite time,
so further tripping action must be performed. Tripping from the breaker failure scheme should trip all breakers, both local
and remote, that can supply current to the faulted zone. Usually operation of a breaker failure element will cause clearing of
a larger section of the power system than the initial trip. Because breaker failure can result in tripping a large number of
breakers and this affects system safety and stability, a very high level of security is required.
Two schemes are provided: one for three-pole tripping only (identified by the name “3BF”) and one for three pole plus sin-
gle-pole operation (identified by the name “1BF”). The philosophy used in these schemes is identical. The operation of a
breaker failure element includes three stages: initiation, determination of a breaker failure condition, and output.
INITIATION STAGE:
A FlexLogic™ operand representing the protection trip signal initially sent to the breaker must be selected to initiate the
scheme. The initiating signal should be sealed-in if primary fault detection can reset before the breaker failure timers have
finished timing. The seal-in is supervised by current level, so it is reset when the fault is cleared. If desired, an incomplete
sequence seal-in reset can be implemented by using the initiating operand to also initiate a FlexLogic™ timer, set longer
than any breaker failure timer, whose output operand is selected to block the breaker failure scheme.
Schemes can be initiated either directly or with current level supervision. It is particularly important in any application to
decide if a current-supervised initiate is to be used. The use of a current-supervised initiate results in the breaker failure ele-
ment not being initiated for a breaker that has very little or no current flowing through it, which may be the case for trans-
former faults. For those situations where it is required to maintain breaker fail coverage for fault levels below the BF1 PH
AMP SUPV PICKUP or the BF1 N AMP SUPV PICKUP setting, a current supervised initiate should not be used. This feature
should be utilized for those situations where coordinating margins may be reduced when high speed reclosing is used.
Thus, if this choice is made, fault levels must always be above the supervision pickup levels for dependable operation of
the breaker fail scheme. This can also occur in breaker-and-a-half or ring bus configurations where the first breaker closes
into a fault; the protection trips and attempts to initiate breaker failure for the second breaker, which is in the process of
closing, but does not yet have current flowing through it.
When the scheme is initiated, it immediately sends a trip signal to the breaker initially signaled to trip (this feature is usually
described as re-trip). This reduces the possibility of widespread tripping that results from a declaration of a failed breaker.
DETERMINATION OF A BREAKER FAILURE CONDITION:
The schemes determine a breaker failure condition via three paths. Each of these paths is equipped with a time delay, after
which a failed breaker is declared and trip signals are sent to all breakers required to clear the zone. The delayed paths are
associated with breaker failure timers 1, 2, and 3, which are intended to have delays increasing with increasing timer num-
bers. These delayed paths are individually enabled to allow for maximum flexibility.
Timer 1 logic (early path) is supervised by a fast-operating breaker auxiliary contact. If the breaker is still closed (as indi-
cated by the auxiliary contact) and fault current is detected after the delay interval, an output is issued. Operation of the
breaker auxiliary switch indicates that the breaker has mechanically operated. The continued presence of current indicates
that the breaker has failed to interrupt the circuit.
Timer 2 logic (main path) is not supervised by a breaker auxiliary contact. If fault current is detected after the delay interval,
an output is issued. This path is intended to detect a breaker that opens mechanically but fails to interrupt fault current; the
logic therefore does not use a breaker auxiliary contact.
The timer 1 and 2 paths provide two levels of current supervision, high-set and low-set, that allow the supervision level to
change from a current which flows before a breaker inserts an opening resistor into the faulted circuit to a lower level after
resistor insertion. The high-set detector is enabled after timeout of timer 1 or 2, along with a timer that will enable the low-
set detector after its delay interval. The delay interval between high-set and low-set is the expected breaker opening time.
Both current detectors provide a fast operating time for currents at small multiples of the pickup value. The overcurrent
detectors are required to operate after the breaker failure delay interval to eliminate the need for very fast resetting overcur-
rent detectors.
Timer 3 logic (slow path) is supervised by a breaker auxiliary contact and a control switch contact used to indicate that the
breaker is in or out-of-service, disabling this path when the breaker is out-of-service for maintenance. There is no current
level check in this logic as it is intended to detect low magnitude faults and it is therefore the slowest to operate. 5
OUTPUT:
The outputs from the schemes are:
• FlexLogic™ operands that report on the operation of portions of the scheme
• FlexLogic™ operand used to re-trip the protected breaker
• FlexLogic™ operands that initiate tripping required to clear the faulted zone. The trip output can be sealed-in for an
adjustable period.
• Target message indicating a failed breaker has been declared
• Illumination of the faceplate Trip LED (and the Phase A, B or C LED, if applicable)

the supervision pickup level.
BF1 USE SEAL-IN: If set to "Yes", the element will only be sealed-in if current flowing through the breaker is above the
supervision pickup level.
• BF1 3-POLE INITIATE: This setting selects the FlexLogic™ operand that will initiate three-pole tripping of the breaker.
• BF1 PH AMP SUPV PICKUP: This setting is used to set the phase current initiation and seal-in supervision level.
Generally this setting should detect the lowest expected fault current on the protected breaker. It can be set as low as
necessary (lower than breaker resistor current or lower than load current) – high-set and low-set current supervision
will guarantee correct operation.
• BF1 N AMP SUPV PICKUP: This setting is used to set the neutral current initiate and seal-in supervision level. Gener-
ally this setting should detect the lowest expected fault current on the protected breaker. Neutral current supervision is
used only in the three phase scheme to provide increased sensitivity. This setting is valid only for three-pole tripping
schemes.
• BF1 USE TIMER 1: If set to "Yes", the early path is operational.
• BF1 TIMER 1 PICKUP DELAY: Timer 1 is set to the shortest time required for breaker auxiliary contact Status-1 to
open, from the time the initial trip signal is applied to the breaker trip circuit, plus a safety margin.
• BF1 USE TIMER 2: If set to "Yes", the main path is operational.
• BF1 TIMER 2 PICKUP DELAY: Timer 2 is set to the expected opening time of the breaker, plus a safety margin. This
safety margin was historically intended to allow for measuring and timing errors in the breaker failure scheme equip-
ment. In microprocessor relays this time is not significant. In T60 relays, which use a Fourier transform, the calculated
current magnitude will ramp-down to zero one power frequency cycle after the current is interrupted, and this lag
should be included in the overall margin duration, as it occurs after current interruption. The Breaker failure main path
sequence diagram below shows a margin of two cycles; this interval is considered the minimum appropriate for most
applications.
Note that in bulk oil circuit breakers, the interrupting time for currents less than 25% of the interrupting rating can be
significantly longer than the normal interrupting time.
• BF1 USE TIMER 3: If set to "Yes", the Slow Path is operational.
• BF1 TIMER 3 PICKUP DELAY: Timer 3 is set to the same interval as timer 2, plus an increased safety margin.
Because this path is intended to operate only for low level faults, the delay can be in the order of 300 to 500 ms.
• BF1 BKR POS1 A/3P: This setting selects the FlexLogic™ operand that represents the protected breaker early-type
auxiliary switch contact (52/a). When using the single-pole breaker failure scheme, this operand represents the pro-
tected breaker early-type auxiliary switch contact on pole A. This is normally a non-multiplied form-A contact. The con-
tact may even be adjusted to have the shortest possible operating time.
• BF1 BKR POS2 A/3P: This setting selects the FlexLogic™ operand that represents the breaker normal-type auxiliary
switch contact (52/a). When using the single-pole breaker failure scheme, this operand represents the protected
breaker auxiliary switch contact on pole A. This may be a multiplied contact.
• BF1 BREAKER TEST ON: This setting is used to select the FlexLogic™ operand that represents the breaker in-ser-
vice/out-of-service switch set to the out-of-service position.
• BF1 PH AMP HISET PICKUP: This setting sets the phase current output supervision level. Generally this setting
should detect the lowest expected fault current on the protected breaker, before a breaker opening resistor is inserted.
• BF1 N AMP HISET PICKUP: This setting sets the neutral current output supervision level. Generally this setting
should detect the lowest expected fault current on the protected breaker, before a breaker opening resistor is inserted.
Neutral current supervision is used only in the three pole scheme to provide increased sensitivity. This setting is valid
only for three-pole breaker failure schemes.
• BF1 PH AMP LOSET PICKUP: This setting sets the phase current output supervision level. Generally this setting
should detect the lowest expected fault current on the protected breaker, after a breaker opening resistor is inserted
(approximately 90% of the resistor current).
• BF1 N AMP LOSET PICKUP: This setting sets the neutral current output supervision level. Generally this setting
should detect the lowest expected fault current on the protected breaker, after a breaker opening resistor is inserted
(approximately 90% of the resistor current). This setting is valid only for three-pole breaker failure schemes.
• BF1 LOSET TIME DELAY: Sets the pickup delay for current detection after opening resistor insertion.
• BF1 TRIP DROPOUT DELAY: This setting is used to set the period of time for which the trip output is sealed-in. This
timer must be coordinated with the automatic reclosing scheme of the failed breaker, to which the breaker failure ele-
5
ment sends a cancel reclosure signal. Reclosure of a remote breaker can also be prevented by holding a transfer trip
signal on longer than the reclaim time.
• BF1 PH A INITIATE / BF1 PH B INITIATE / BF 1 PH C INITIATE: These settings select the FlexLogic™ operand to ini-
tiate phase A, B, or C single-pole tripping of the breaker and the phase A, B, or C portion of the scheme, accordingly.
This setting is only valid for single-pole breaker failure schemes.
• BF1 BKR POS1 B / BF1 BKR POS 1 C: These settings select the FlexLogic™ operand to represents the protected
breaker early-type auxiliary switch contact on poles B or C, accordingly. This contact is normally a non-multiplied Form-
A contact. The contact may even be adjusted to have the shortest possible operating time. This setting is valid only for
single-pole breaker failure schemes.
• BF1 BKR POS2 B: Selects the FlexLogic™ operand that represents the protected breaker normal-type auxiliary
switch contact on pole B (52/a). This may be a multiplied contact. This setting is valid only for single-pole breaker fail-
ure schemes.
• BF1 BKR POS2 C: This setting selects the FlexLogic™ operand that represents the protected breaker normal-type
auxiliary switch contact on pole C (52/a). This may be a multiplied contact. For single-pole operation, the scheme has
the same overall general concept except that it provides re-tripping of each single pole of the protected breaker. The
approach shown in the following single pole tripping diagram uses the initiating information to determine which pole is
supposed to trip. The logic is segregated on a per-pole basis. The overcurrent detectors have ganged settings. This
setting is valid only for single-pole breaker failure schemes.
Upon operation of the breaker failure element for a single pole trip command, a three-pole trip command should be
given via output operand BKR FAIL 1 TRIP OP.

These protection elements can be used for a variety of applications such as:
• Undervoltage Protection: For voltage sensitive loads, such as induction motors, a drop in voltage increases the
drawn current which may cause dangerous overheating in the motor. The undervoltage protection feature can be used
to either cause a trip or generate an alarm when the voltage drops below a specified voltage setting for a specified time
delay.
• Permissive Functions: The undervoltage feature may be used to block the functioning of external devices by operat-
ing an output relay when the voltage falls below the specified voltage setting. The undervoltage feature may also be
used to block the functioning of other elements through the block feature of those elements.
• Source Transfer Schemes: In the event of an undervoltage, a transfer signal may be generated to transfer a load
from its normal source to a standby or emergency power source.
The undervoltage elements can be programmed to have a definite time delay characteristic. The definite time curve oper-
ates when the voltage drops below the pickup level for a specified period of time. The time delay is adjustable from 0 to
600.00 seconds in steps of 0.01. The undervoltage elements can also be programmed to have an inverse time delay char-
acteristic.
The undervoltage delay setting defines the family of curves shown below.

The T60 contains one auxiliary overvoltage element for each VT bank. This element is intended for monitoring overvoltage
conditions of the auxiliary voltage. The nominal secondary voltage of the auxiliary voltage channel entered under SYSTEM
SETUP AC INPUTS VOLTAGE BANK X5 AUXILIARY VT X5 SECONDARY is the per-unit (pu) base used when setting the 5

The per-unit volts-per-hertz (V/Hz) value is calculated using the maximum of the three-phase voltage inputs or the auxiliary
voltage channel Vx input, if the source is not configured with phase voltages. To use the V/Hz element with auxiliary volt-
age, set SYSTEM SETUP SIGNAL SOURCES SOURCE 1(6) SOURCE 1(6) PHASE VT to “None” and SOURCE 1(6) AUX VT
to the corresponding voltage input bank. If there is no voltage on the relay terminals in either case, the per-unit V/Hz value
is automatically set to “0”. The per unit value is established as per voltage and nominal frequency power system settings as
follows:
1. If the phase voltage inputs defined in the source menu are used for V/Hz operation, then “1 pu” is the selected SYSTEM
SETUP AC INPUTS VOLTAGE BANK N PHASE VT N SECONDARY setting, divided by the divided by the SYSTEM
SETUP POWER SYSTEM NOMINAL FREQUENCY setting.
2. If the voltage bank connection value is selected as “Delta”, then the phase-to-phase nominal voltage is used to define
the per-unit value. If the voltage bank connection value is selected as “Wye”, then the VOLTS/HZ 1 VOLTAGE MODE set-
ting further defines the operating quantity and per-unit value for this element. If the voltage mode is set as “Phase-
phase”, then the operating quantity for this element will be phase-to-phase nominal voltage. Likewise, if the voltage
mode is set to “Phase-ground”, then the operating quantity for this element will be the phase-to-ground nominal volt-
age. It is beneficial to use the phase-to-phase voltage mode for this element when the T60 device is applied on an iso-
lated or resistance-grounded system.
3. When the auxiliary voltage Vx is used (regarding the condition for “None” phase voltage setting mentioned above),
then the 1 pu value is the SYSTEM SETUP AC INPUTS VOLTAGE BANK N AUXILIARY VT N SECONDARY setting
divided by the SYSTEM SETUP POWER SYSTEM NOMINAL FREQUENCY setting.
4. If V/Hz source is configured with both phase and auxiliary voltages, the maximum phase among the three voltage
channels at any given point in time is the input voltage signal for element operation, and therefore the per-unit value
will be calculated as described in Step 1 above. If the measured voltage of all three phase voltages is 0, than the per-
unit value becomes automatically 0 regardless of the presence of auxiliary voltage.

Control elements are generally used for control rather than protection. See the Introduction to Elements section at the
beginning of this chapter for further information.
The trip bus element allows aggregating outputs of protection and control elements without using FlexLogic™ and assign-
ing them a simple and effective manner. Each trip bus can be assigned for either trip or alarm actions. Simple trip condition-
ing such as latch, delay, and seal-in delay are available.
The easiest way to assign element outputs to a trip bus is through the EnerVista UR Setup software A protection summary
is displayed by navigating to a specific protection or control protection element and checking the desired bus box. Once the
desired element is selected for a specific bus, a list of element operate-type operands are displayed and can be assigned
to a trip bus. If more than one operate-type operand is required, it may be assigned directly from the trip bus menu.

GROUP 6 NAME: Range: up to 16 alphanumeric characters
The setting groups menu controls the activation and deactivation of up to six possible groups of settings in the GROUPED
ELEMENTS settings menu. The faceplate Settings In Use LEDs indicate which active group (with a non-flashing energized
LED) is in service.
The SETTING GROUPS BLK setting prevents the active setting group from changing when the FlexLogic™ parameter is set to
"On". This can be useful in applications where it is undesirable to change the settings under certain conditions, such as the
breaker being open.
The GROUP 2 ACTIVATE ON to GROUP 6 ACTIVATE ON settings select a FlexLogic™ operand which, when set, will make the
particular setting group active for use by any grouped element. A priority scheme ensures that only one group is active at a
given time – the highest-numbered group which is activated by its ACTIVATE ON parameter takes priority over the lower-
numbered groups. There is no activate on setting for group 1 (the default active group), because group 1 automatically
becomes active if no other group is active.
The SETTING GROUP 1 NAME to SETTING GROUP 6 NAME settings allows to user to assign a name to each of the six settings
groups. Once programmed, this name will appear on the second line of the GROUPED ELEMENTS SETTING GROUP 1(6)
menu display.
The relay can be set up via a FlexLogic™ equation to receive requests to activate or de-activate a particular non-default
settings group. The following FlexLogic™ equation (see the figure below) illustrates requests via remote communications
(for example, VIRTUAL INPUT 1 ON) or from a local contact input (for example, CONTACT IP 1 ON) to initiate the use of a par-
ticular settings group, and requests from several overcurrent pickup measuring elements to inhibit the use of the particular
settings group. The assigned VIRTUAL OUTPUT 1 operand is used to control the “On” state of a particular settings group.

The selector switch element is intended to replace a mechanical selector switch. Typical applications include setting group
control or control of multiple logic sub-circuits in user-programmable logic.
The element provides for two control inputs. The step-up control allows stepping through selector position one step at a
time with each pulse of the control input, such as a user-programmable pushbutton. The three-bit control input allows set-
ting the selector to the position defined by a three-bit word.
The element allows pre-selecting a new position without applying it. The pre-selected position gets applied either after time-
out or upon acknowledgement via separate inputs (user setting). The selector position is stored in non-volatile memory.
Upon power-up, either the previous position is restored or the relay synchronizes to the current three-bit word (user set-
ting). Basic alarm functionality alerts the user under abnormal conditions; for example, the three-bit control input being out
of range.
• SELECTOR 1 FULL RANGE: This setting defines the upper position of the selector. When stepping up through avail-
able positions of the selector, the upper position wraps up to the lower position (position 1). When using a direct three-
bit control word for programming the selector to a desired position, the change would take place only if the control word
is within the range of 1 to the SELECTOR FULL RANGE. If the control word is outside the range, an alarm is established
by setting the SELECTOR ALARM FlexLogic™ operand for 3 seconds.
• SELECTOR 1 TIME-OUT: This setting defines the time-out period for the selector. This value is used by the relay in
the following two ways. When the SELECTOR STEP-UP MODE is “Time-out”, the setting specifies the required period of
inactivity of the control input after which the pre-selected position is automatically applied. When the SELECTOR STEP-
UP MODE is “Acknowledge”, the setting specifies the period of time for the acknowledging input to appear. The timer is
re-started by any activity of the control input. The acknowledging input must come before the SELECTOR 1 TIME-OUT
timer expires; otherwise, the change will not take place and an alarm will be set.
• SELECTOR 1 STEP-UP: This setting specifies a control input for the selector switch. The switch is shifted to a new
position at each rising edge of this signal. The position changes incrementally, wrapping up from the last (SELECTOR 1
5 FULL RANGE) to the first (position 1). Consecutive pulses of this control operand must not occur faster than every
50 ms. After each rising edge of the assigned operand, the time-out timer is restarted and the SELECTOR SWITCH 1:
POS Z CHNG INITIATED target message is displayed, where Z the pre-selected position. The message is displayed for
the time specified by the FLASH MESSAGE TIME setting. The pre-selected position is applied after the selector times out
(“Time-out” mode), or when the acknowledging signal appears before the element times out (“Acknowledge” mode).
When the new position is applied, the relay displays the SELECTOR SWITCH 1: POSITION Z IN USE message. Typically,
a user-programmable pushbutton is configured as the stepping up control input.
• SELECTOR 1 STEP-UP MODE: This setting defines the selector mode of operation. When set to “Time-out”, the
selector will change its position after a pre-defined period of inactivity at the control input. The change is automatic and
does not require any explicit confirmation of the intent to change the selector's position. When set to “Acknowledge”,
the selector will change its position only after the intent is confirmed through a separate acknowledging signal. If the
acknowledging signal does not appear within a pre-defined period of time, the selector does not accept the change
and an alarm is established by setting the SELECTOR STP ALARM output FlexLogic™ operand for 3 seconds.
• SELECTOR 1 ACK: This setting specifies an acknowledging input for the stepping up control input. The pre-selected
position is applied on the rising edge of the assigned operand. This setting is active only under “Acknowledge” mode of
operation. The acknowledging signal must appear within the time defined by the SELECTOR 1 TIME-OUT setting after the
last activity of the control input. A user-programmable pushbutton is typically configured as the acknowledging input.
• SELECTOR 1 3BIT A0, A1, and A2: These settings specify a three-bit control input of the selector. The three-bit con-
trol word pre-selects the position using the following encoding convention:
A2 A1 A0 POSITION
0 0 0 rest
0 0 1 1
0 1 0 2
0 1 1 3
1 0 0 4
1 0 1 5
1 1 0 6
1 1 1 7
The “rest” position (0, 0, 0) does not generate an action and is intended for situations when the device generating the
three-bit control word is having a problem. When SELECTOR 1 3BIT MODE is “Time-out”, the pre-selected position is
applied in SELECTOR 1 TIME-OUT seconds after the last activity of the three-bit input. When SELECTOR 1 3BIT MODE is
“Acknowledge”, the pre-selected position is applied on the rising edge of the SELECTOR 1 3BIT ACK acknowledging
input.
The stepping up control input (SELECTOR 1 STEP-UP) and the three-bit control inputs (SELECTOR 1 3BIT A0 through A2)
lock-out mutually: once the stepping up sequence is initiated, the three-bit control input is inactive; once the three-bit
control sequence is initiated, the stepping up input is inactive.
• SELECTOR 1 3BIT MODE: This setting defines the selector mode of operation. When set to “Time-out”, the selector
changes its position after a pre-defined period of inactivity at the control input. The change is automatic and does not
require explicit confirmation to change the selector position. When set to “Acknowledge”, the selector changes its posi-
tion only after confirmation via a separate acknowledging signal. If the acknowledging signal does not appear within a
pre-defined period of time, the selector rejects the change and an alarm established by invoking the SELECTOR BIT
ALARM FlexLogic™ operand for 3 seconds.
• SELECTOR 1 3BIT ACK: This setting specifies an acknowledging input for the three-bit control input. The pre-
selected position is applied on the rising edge of the assigned FlexLogic™ operand. This setting is active only under
the “Acknowledge” mode of operation. The acknowledging signal must appear within the time defined by the SELEC-
TOR TIME-OUT setting after the last activity of the three-bit control inputs. Note that the stepping up control input and
three-bit control input have independent acknowledging signals (SELECTOR 1 ACK and SELECTOR 1 3BIT ACK, accord-
ingly).
• SELECTOR 1 POWER-UP MODE: This setting specifies the element behavior on power up of the relay.
When set to “Restore”, the last position of the selector (stored in the non-volatile memory) is restored after powering up
the relay. If the position restored from memory is out of range, position 0 (no output operand selected) is applied and
an alarm is set (SELECTOR 1 PWR ALARM).
5
When set to “Synchronize” selector switch acts as follows. For two power cycles, the selector applies position 0 to the
switch and activates SELECTOR 1 PWR ALARM. After two power cycles expire, the selector synchronizes to the position
dictated by the three-bit control input. This operation does not wait for time-out or the acknowledging input. When the
synchronization attempt is unsuccessful (that is, the three-bit input is not available (0,0,0) or out of range) then the
selector switch output is set to position 0 (no output operand selected) and an alarm is established (SELECTOR 1 PWR
ALARM).
The operation of “Synch/Restore” mode is similar to the “Synchronize” mode. The only difference is that after an
unsuccessful synchronization attempt, the switch will attempt to restore the position stored in the relay memory. The
“Synch/Restore” mode is useful for applications where the selector switch is employed to change the setting group in
redundant (two relay) protection schemes.
• SELECTOR 1 EVENTS: If enabled, the following events are logged:

5.7.7 SYNCHROCHECK
The T60 Transformer Protection System is provided with an optional synchrocheck element. This element
is specified as a software option (select “10” or “11”) at the time of ordering. Refer to the Ordering section
of chapter 2 for additional details.

where: = phase angle difference in degrees; F = frequency difference in Hz.
If one or both sources are de-energized, the synchrocheck programming can allow for closing of the circuit breaker using
undervoltage control to by-pass the synchrocheck measurements (dead source function).
• SYNCHK1 V1 SOURCE: This setting selects the source for voltage V1 (see NOTES below).
• SYNCHK1 V2 SOURCE: This setting selects the source for voltage V2, which must not be the same as used for the
V1 (see NOTES below).
• SYNCHK1 MAX VOLT DIFF: This setting selects the maximum primary voltage difference in volts between the two
sources. A primary voltage magnitude difference between the two input voltages below this value is within the permis-
sible limit for synchronism.
• SYNCHK1 MAX ANGLE DIFF: This setting selects the maximum angular difference in degrees between the two
sources. An angular difference between the two input voltage phasors below this value is within the permissible limit
for synchronism.
• SYNCHK1 MAX FREQ DIFF: This setting selects the maximum frequency difference in ‘Hz’ between the two sources.
A frequency difference between the two input voltage systems below this value is within the permissible limit for syn-
chronism.
• SYNCHK1 MAX FREQ HYSTERESIS: This setting specifies the required hysteresis for the maximum frequency differ-
ence condition. The condition becomes satisfied when the frequency difference becomes lower than SYNCHK1 MAX
FREQ DIFF. Once the Synchrocheck element has operated, the frequency difference must increase above the SYNCHK1
MAX FREQ DIFF + SYNCHK1 MAX FREQ HYSTERESIS sum to drop out (assuming the other two conditions, voltage and
5 angle, remain satisfied).
• SYNCHK1 DEAD SOURCE SELECT: This setting selects the combination of dead and live sources that will by-pass
synchronism check function and permit the breaker to be closed when one or both of the two voltages (V1 or/and V2)
are below the maximum voltage threshold. A dead or live source is declared by monitoring the voltage level. Six
options are available:
None: Dead Source function is disabled
LV1 and DV2: Live V1 and Dead V2
DV1 and LV2: Dead V1 and Live V2
DV1 or DV2: Dead V1 or Dead V2
DV1 Xor DV2: Dead V1 exclusive-or Dead V2 (one source is Dead and the other is Live)
DV1 and DV2: Dead V1 and Dead V2
• SYNCHK1 DEAD V1 MAX VOLT: This setting establishes a maximum voltage magnitude for V1 in 1 ‘pu’. Below this
magnitude, the V1 voltage input used for synchrocheck will be considered “Dead” or de-energized.
• SYNCHK1 DEAD V2 MAX VOLT: This setting establishes a maximum voltage magnitude for V2 in ‘pu’. Below this
magnitude, the V2 voltage input used for synchrocheck will be considered “Dead” or de-energized.
• SYNCHK1 LIVE V1 MIN VOLT: This setting establishes a minimum voltage magnitude for V1 in ‘pu’. Above this mag-
nitude, the V1 voltage input used for synchrocheck will be considered “Live” or energized.
• SYNCHK1 LIVE V2 MIN VOLT: This setting establishes a minimum voltage magnitude for V2 in ‘pu’. Above this mag-
nitude, the V2 voltage input used for synchrocheck will be considered “Live” or energized.
The voltages V1 and V2 will be matched automatically so that the corresponding voltages from the two sources will be
used to measure conditions. A phase to phase voltage will be used if available in both sources; if one or both of the
Sources have only an auxiliary voltage, this voltage will be used. For example, if an auxiliary voltage is programmed to
VAG, the synchrocheck element will automatically select VAG from the other source. If the comparison is required on a
specific voltage, the user can externally connect that specific voltage to auxiliary voltage terminals and then use this
"Auxiliary Voltage" to check the synchronism conditions.
If using a single CT/VT module with both phase voltages and an auxiliary voltage, ensure that only the auxiliary voltage 5
is programmed in one of the sources to be used for synchrocheck.
Exception: Synchronism cannot be checked between Delta connected phase VTs and a Wye con-
nected auxiliary voltage.
NOTE
2. The relay measures frequency and Volts/Hz from an input on a given source with priorities as established by the con-
figuration of input channels to the source. The relay will use the phase channel of a three-phase set of voltages if pro-
grammed as part of that source. The relay will use the auxiliary voltage channel only if that channel is programmed as
part of the Source and a three-phase set is not.

As long as the current through the voltage monitor is above a threshold (see technical specifications for form-A), the “Cont
Op 1 VOn” FlexLogic™ operand will be set (for contact input 1 – corresponding operands exist for each contact output). If
the output circuit has a high resistance or the DC current is interrupted, the trickle current will drop below the threshold and
the “Cont Op 1 VOff” FlexLogic™ operand will be set. Consequently, the state of these operands can be used as indicators
of the integrity of the circuits in which form-A contacts are inserted.
EXAMPLE 1: BREAKER TRIP CIRCUIT INTEGRITY MONITORING
In many applications it is desired to monitor the breaker trip circuit integrity so problems can be detected before a trip oper-
ation is required. The circuit is considered to be healthy when the voltage monitor connected across the trip output contact
detects a low level of current, well below the operating current of the breaker trip coil. If the circuit presents a high resis-
tance, the trickle current will fall below the monitor threshold and an alarm would be declared.
In most breaker control circuits, the trip coil is connected in series with a breaker auxiliary contact which is open when the
breaker is open (see diagram below). To prevent unwanted alarms in this situation, the trip circuit monitoring logic must
include the breaker position.

There are 8 identical digital counters, numbered from 1 to 8. A digital counter counts the number of state transitions from
Logic 0 to Logic 1. The counter is used to count operations such as the pickups of an element, the changes of state of an
external contact (e.g. breaker auxiliary switch), or pulses from a watt-hour meter.
• COUNTER 1 UNITS: Assigns a label to identify the unit of measure pertaining to the digital transitions to be counted.
The units label will appear in the corresponding actual values status.
• COUNTER 1 PRESET: Sets the count to a required preset value before counting operations begin, as in the case
where a substitute relay is to be installed in place of an in-service relay, or while the counter is running.
• COUNTER 1 COMPARE: Sets the value to which the accumulated count value is compared. Three FlexLogic™ output
operands are provided to indicate if the present value is ‘more than (HI)’, ‘equal to (EQL)’, or ‘less than (LO)’ the set
value.
• COUNTER 1 UP: Selects the FlexLogic™ operand for incrementing the counter. If an enabled UP input is received
when the accumulated value is at the limit of +2,147,483,647 counts, the counter will rollover to –2,147,483,648.
• COUNTER 1 DOWN: Selects the FlexLogic™ operand for decrementing the counter. If an enabled DOWN input is
received when the accumulated value is at the limit of –2,147,483,648 counts, the counter will rollover to
+2,147,483,647.
• COUNTER 1 BLOCK: Selects the FlexLogic™ operand for blocking the counting operation. All counter operands are
blocked.
• CNT1 SET TO PRESET: Selects the FlexLogic™ operand used to set the count to the preset value. The counter will
be set to the preset value in the following situations:
1. When the counter is enabled and the CNT1 SET TO PRESET operand has the value 1 (when the counter is enabled
and CNT1 SET TO PRESET operand is 0, the counter will be set to 0).
2. When the counter is running and the CNT1 SET TO PRESET operand changes the state from 0 to 1 (CNT1 SET TO
PRESET changing from 1 to 0 while the counter is running has no effect on the count).
3. When a reset or reset/freeze command is sent to the counter and the CNT1 SET TO PRESET operand has the value
1 (when a reset or reset/freeze command is sent to the counter and the CNT1 SET TO PRESET operand has the
value 0, the counter will be set to 0).
• COUNTER 1 RESET: Selects the FlexLogic™ operand for setting the count to either “0” or the preset value depending
on the state of the CNT1 SET TO PRESET operand.
• COUNTER 1 FREEZE/RESET: Selects the FlexLogic™ operand for capturing (freezing) the accumulated count value
into a separate register with the date and time of the operation, and resetting the count to “0”.
• COUNTER 1 FREEZE/COUNT: Selects the FlexLogic™ operand for capturing (freezing) the accumulated count value
into a separate register with the date and time of the operation, and continuing counting. The present accumulated
value and captured frozen value with the associated date/time stamp are available as actual values. If control power is
interrupted, the accumulated and frozen values are saved into non-volatile memory during the power down operation.

PROTECTION
There is one breaker arcing current element available per CT bank, with a minimum of two elements. This element calcu-
lates an estimate of the per-phase wear on the breaker contacts by measuring and integrating the current squared passing
through the breaker contacts as an arc. These per-phase values are added to accumulated totals for each phase and com-
pared to a programmed threshold value. When the threshold is exceeded in any phase, the relay can set an output operand
to “1”. The accumulated value for each phase can be displayed as an actual value.
The operation of the scheme is shown in the following logic diagram. The same output operand that is selected to operate
the output relay used to trip the breaker, indicating a tripping sequence has begun, is used to initiate this feature. A time
delay is introduced between initiation and the starting of integration to prevent integration of current flow through the
breaker before the contacts have parted. This interval includes the operating time of the output relay, any other auxiliary
relays and the breaker mechanism. For maximum measurement accuracy, the interval between change-of-state of the
operand (from 0 to 1) and contact separation should be measured for the specific installation. Integration of the measured
current continues for 100 ms, which is expected to include the total arcing period.
The feature is programmed to perform fault duration calculations. Fault duration is defined as a time between operation of
the disturbance detector occurring before initiation of this feature, and reset of an internal low-set overcurrent function. Cor-
rection is implemented to account for a non-zero reset time of the overcurrent function.
Breaker arcing currents and fault duration values are available under the ACTUAL VALUES RECORDS MAINTENANCE
BREAKER 1(4) menus.
• BKR 1 ARC AMP INT-A(C): Select the same output operands that are configured to operate the output relays used to
trip the breaker. In three-pole tripping applications, the same operand should be configured to initiate arcing current
calculations for poles A, B and C of the breaker. In single-pole tripping applications, per-pole tripping operands should
be configured to initiate the calculations for the poles that are actually tripped.
• BKR 1 ARC AMP DELAY: This setting is used to program the delay interval between the time the tripping sequence is
initiated and the time the breaker contacts are expected to part, starting the integration of the measured current.
• BKR 1 ARC AMP LIMIT: Selects the threshold value above which the output operand is set.

The thermal overload protection element corresponds to the IEC 255-8 standard and is used to detect thermal overload
conditions in protected power system elements. Choosing an appropriate time constant element can be used to protect dif-
ferent elements of the power system. The cold curve characteristic is applied when the previous averaged load current over
the last 5 cycles is less than 10% of the base current. If this current is greater or equal than 10% than the base current, then
the hot curve characteristic is applied.
The IEC255-8 cold curve is defined as follows:

CONTACT INPUTS
CONTACT INPUT
THRESHOLDS
The contact inputs menu contains configuration settings for each contact input as well as voltage thresholds for each group
of four contact inputs. Upon startup, the relay processor determines (from an assessment of the installed modules) which
contact inputs are available and then display settings for only those inputs.
An alphanumeric ID may be assigned to a contact input for diagnostic, setting, and event recording purposes. The CON-
TACT IP X On” (Logic 1) FlexLogic™ operand corresponds to contact input “X” being closed, while CONTACT IP X Off corre-
sponds to contact input “X” being open. The CONTACT INPUT DEBNCE TIME defines the time required for the contact to
overcome ‘contact bouncing’ conditions. As this time differs for different contact types and manufacturers, set it as a maxi-
mum contact debounce time (per manufacturer specifications) plus some margin to ensure proper operation. If CONTACT
INPUT EVENTS is set to “Enabled”, every change in the contact input state will trigger an event.
A raw status is scanned for all Contact Inputs synchronously at the constant rate of 0.5 ms as shown in the figure below.
The DC input voltage is compared to a user-settable threshold. A new contact input state must be maintained for a user-
settable debounce time in order for the T60 to validate the new contact state. In the figure below, the debounce time is set
at 2.5 ms; thus the 6th sample in a row validates the change of state (mark no. 1 in the diagram). Once validated (de-
bounced), the contact input asserts a corresponding FlexLogic™ operand and logs an event as per user setting.
A time stamp of the first sample in the sequence that validates the new state is used when logging the change of the con-
tact input into the Event Recorder (mark no. 2 in the diagram).
Protection and control elements, as well as FlexLogic™ equations and timers, are executed eight times in a power system
cycle. The protection pass duration is controlled by the frequency tracking mechanism. The FlexLogic™ operand reflecting
the debounced state of the contact is updated at the protection pass following the validation (marks no. 3 and 4 on the fig-
ure below). The update is performed at the beginning of the protection pass so all protection and control functions, as well
as FlexLogic™ equations, are fed with the updated states of the contact inputs.
The FlexLogic™ operand response time to the contact input change is equal to the debounce time setting plus up to one
protection pass (variable and depending on system frequency if frequency tracking enabled). If the change of state occurs
just after a protection pass, the recognition is delayed until the subsequent protection pass; that is, by the entire duration of
the protection pass. If the change occurs just prior to a protection pass, the state is recognized immediately. Statistically a
delay of half the protection pass is expected. Owing to the 0.5 ms scan rate, the time resolution for the input contact is
below 1msec.
For example, 8 protection passes per cycle on a 60 Hz system correspond to a protection pass every 2.1 ms. With a con-
tact debounce time setting of 3.0 ms, the FlexLogic™ operand-assert time limits are: 3.0 + 0.0 = 3.0 ms and 3.0 + 2.1 = 5.1
ms. These time limits depend on how soon the protection pass runs after the debouncing time.
Regardless of the contact debounce time setting, the contact input event is time-stamped with a 1 s accuracy using the
time of the first scan corresponding to the new state (mark no. 2 below). Therefore, the time stamp reflects a change in the
DC voltage across the contact input terminals that was not accidental as it was subsequently validated using the debounce
timer. Keep in mind that the associated FlexLogic™ operand is asserted/de-asserted later, after validating the change.
The debounce algorithm is symmetrical: the same procedure and debounce time are used to filter the LOW-HIGH (marks
no.1, 2, 3, and 4 in the figure below) and HIGH-LOW (marks no. 5, 6, 7, and 8 below) transitions.

Figure 5–144: INPUT CONTACT DEBOUNCING MECHANISM AND TIME-STAMPING SAMPLE TIMING
Contact inputs are isolated in groups of four to allow connection of wet contacts from different voltage sources for each
group. The CONTACT INPUT THRESHOLDS determine the minimum voltage required to detect a closed contact input. This
value should be selected according to the following criteria: 17 for 24 V sources, 33 for 48 V sources, 84 for 110 to 125 V
sources and 166 for 250 V sources.
For example, to use contact input H5a as a status input from the breaker 52b contact to seal-in the trip relay and record it in
the Event Records menu, make the following settings changes:
CONTACT INPUT H5A ID: "Breaker Closed (52b)"
CONTACT INPUT H5A EVENTS: "Enabled"
Note that the 52b contact is closed when the breaker is open and open when the breaker is closed.
There are 64 virtual inputs that can be individually programmed to respond to input signals from the keypad (via the COM-
MANDS menu) and communications protocols. All virtual input operands are defaulted to “Off” (logic 0) unless the appropri-
ate input signal is received.
If the VIRTUAL INPUT x FUNCTION is to “Disabled”, the input will be forced to off (logic 0) regardless of any attempt to alter the
input. If set to “Enabled”, the input operates as shown on the logic diagram and generates output FlexLogic™ operands in
response to received input signals and the applied settings.
There are two types of operation: self-reset and latched. If VIRTUAL INPUT x TYPE is “Self-Reset”, when the input signal tran-
sits from off to on, the output operand will be set to on for only one evaluation of the FlexLogic™ equations and then return
to off. If set to “Latched”, the virtual input sets the state of the output operand to the same state as the most recent received
input.
The self-reset operating mode generates the output operand for a single evaluation of the FlexLogic™ 5
equations. If the operand is to be used anywhere other than internally in a FlexLogic™ equation, it will
NOTE
likely have to be lengthened in time. A FlexLogic™ timer with a delayed reset can perform this function.

a) DIGITAL OUTPUTS
PATH: SETTINGS INPUTS/OUTPUTS CONTACT OUTPUTS CONTACT OUTPUT H1
Upon startup of the relay, the main processor will determine from an assessment of the modules installed in the chassis
which contact outputs are available and present the settings for only these outputs.
An ID may be assigned to each contact output. The signal that can OPERATE a contact output may be any FlexLogic™
operand (virtual output, element state, contact input, or virtual input). An additional FlexLogic™ operand may be used to
SEAL-IN the relay. Any change of state of a contact output can be logged as an Event if programmed to do so.
For example, the trip circuit current is monitored by providing a current threshold detector in series with some Form-A con-
tacts (see the trip circuit example in the Digital elements section). The monitor will set a flag (see the specifications for
Form-A). The name of the FlexLogic™ operand set by the monitor, consists of the output relay designation, followed by the
name of the flag; for example, CONT OP 1 ION.
5 In most breaker control circuits, the trip coil is connected in series with a breaker auxiliary contact used to interrupt current
flow after the breaker has tripped, to prevent damage to the less robust initiating contact. This can be done by monitoring
an auxiliary contact on the breaker which opens when the breaker has tripped, but this scheme is subject to incorrect oper-
ation caused by differences in timing between breaker auxiliary contact change-of-state and interruption of current in the
trip circuit. The most dependable protection of the initiating contact is provided by directly measuring current in the tripping
circuit, and using this parameter to control resetting of the initiating relay. This scheme is often called trip seal-in.
This can be realized in the T60 using the CONT OP 1 ION FlexLogic™ operand to seal-in the contact output as follows:
CONTACT OUTPUT H1 ID: “Cont Op 1"
OUTPUT H1 OPERATE: any suitable FlexLogic™ operand
OUTPUT H1 SEAL-IN: “Cont Op 1 IOn”
CONTACT OUTPUT H1 EVENTS: “Enabled”
b) LATCHING OUTPUTS
PATH: SETTINGS INPUTS/OUTPUTS CONTACT OUTPUTS CONTACT OUTPUT H1a
The T60 latching output contacts are mechanically bi-stable and controlled by two separate (open and close) coils. As such
they retain their position even if the relay is not powered up. The relay recognizes all latching output contact cards and pop-
ulates the setting menu accordingly. On power up, the relay reads positions of the latching contacts from the hardware
before executing any other functions of the relay (such as protection and control features or FlexLogic™).
The latching output modules, either as a part of the relay or as individual modules, are shipped from the factory with all
latching contacts opened. It is highly recommended to double-check the programming and positions of the latching con-
tacts when replacing a module.
Since the relay asserts the output contact and reads back its position, it is possible to incorporate self-monitoring capabili-
ties for the latching outputs. If any latching outputs exhibits a discrepancy, the LATCHING OUTPUT ERROR self-test error is
declared. The error is signaled by the LATCHING OUT ERROR FlexLogic™ operand, event, and target message.
• OUTPUT H1a OPERATE: This setting specifies a FlexLogic™ operand to operate the ‘close coil’ of the contact. The
relay will seal-in this input to safely close the contact. Once the contact is closed and the RESET input is logic 0 (off),
any activity of the OPERATE input, such as subsequent chattering, will not have any effect. With both the OPERATE and
RESET inputs active (logic 1), the response of the latching contact is specified by the OUTPUT H1A TYPE setting.
• OUTPUT H1a RESET: This setting specifies a FlexLogic™ operand to operate the ‘trip coil’ of the contact. The relay
will seal-in this input to safely open the contact. Once the contact is opened and the OPERATE input is logic 0 (off), any
activity of the RESET input, such as subsequent chattering, will not have any effect. With both the OPERATE and RESET
inputs active (logic 1), the response of the latching contact is specified by the OUTPUT H1A TYPE setting.
• OUTPUT H1a TYPE: This setting specifies the contact response under conflicting control inputs; that is, when both the
OPERATE and RESET signals are applied. With both control inputs applied simultaneously, the contact will close if set to
“Operate-dominant” and will open if set to “Reset-dominant”.
Application Example 1:
A latching output contact H1a is to be controlled from two user-programmable pushbuttons (buttons number 1 and 2). The 5
following settings should be applied.
Program the Latching Outputs by making the following changes in the SETTINGS INPUTS/OUTPUTS CONTACT OUT-
PUTS CONTACT OUTPUT H1a menu (assuming an H4L module):
Program the pushbuttons by making the following changes in the PRODUCT SETUP USER-PROGRAMMABLE PUSHBUT-
TONS USER PUSHBUTTON 1 and USER PUSHBUTTON 2 menus:
Application Example 2:
A relay, having two latching contacts H1a and H1c, is to be programmed. The H1a contact is to be a Type-a contact, while
the H1c contact is to be a Type-b contact (Type-a means closed after exercising the operate input; Type-b means closed
after exercising the reset input). The relay is to be controlled from virtual outputs: VO1 to operate and VO2 to reset.
Program the Latching Outputs by making the following changes in the SETTINGS INPUTS/OUTPUTS CONTACT OUT-
PUTS CONTACT OUTPUT H1a and CONTACT OUTPUT H1c menus (assuming an H4L module):
Since the two physical contacts in this example are mechanically separated and have individual control inputs, they will not
operate at exactly the same time. A discrepancy in the range of a fraction of a maximum operating time may occur. There-
fore, a pair of contacts programmed to be a multi-contact relay will not guarantee any specific sequence of operation (such
as make before break). If required, the sequence of operation must be programmed explicitly by delaying some of the con-
trol inputs as shown in the next application example.
Application Example 3:
A make before break functionality must be added to the preceding example. An overlap of 20 ms is required to implement
this functionality as described below:
Both timers (Timer 1 and Timer 2) should be set to 20 ms pickup and 0 ms dropout.
Program the Latching Outputs by making the following changes in the SETTINGS INPUTS/OUTPUTS CONTACT OUT-
PUTS CONTACT OUTPUT H1a and CONTACT OUTPUT H1c menus (assuming an H4L module):
OUTPUT H1a OPERATE: “VO1” OUTPUT H1c OPERATE: “VO2”
OUTPUT H1a RESET: “VO4” OUTPUT H1c RESET: “VO3”
Application Example 4:
A latching contact H1a is to be controlled from a single virtual output VO1. The contact should stay closed as long as VO1
is high, and should stay opened when VO1 is low. Program the relay as follows.
Write the following FlexLogic™ equation (EnerVista UR Setup example shown):

Program the Latching Outputs by making the following changes in the SETTINGS INPUTS/OUTPUTS CONTACT OUT-
PUTS CONTACT OUTPUT H1a menu (assuming an H4L module):
OUTPUT H1a OPERATE: “VO1”
OUTPUT H1a RESET: “VO2”
There are 96 virtual outputs that may be assigned via FlexLogic™. If not assigned, the output will be forced to ‘OFF’ (Logic
0). An ID may be assigned to each virtual output. Virtual outputs are resolved in each pass through the evaluation of the
FlexLogic™ equations. Any change of state of a virtual output can be logged as an event if programmed to do so.
For example, if Virtual Output 1 is the trip signal from FlexLogic™ and the trip relay is used to signal events, the settings
would be programmed as follows:
The sharing of digital point state information between GSSE/GOOSE equipped relays is essentially an extension to Flex-
Logic™, allowing distributed FlexLogic™ by making operands available to/from devices on a common communications net-
work. In addition to digital point states, GSSE/GOOSE messages identify the originator of the message and provide other
information required by the communication specification. All devices listen to network messages and capture data only from
messages that have originated in selected devices.
IEC 61850 GSSE messages are compatible with UCA GOOSE messages and contain a fixed set of digital points. IEC
61850 GOOSE messages can, in general, contain any configurable data items. When used by the remote input/output fea-
ture, IEC 61850 GOOSE messages contain the same data as GSSE messages.
Both GSSE and GOOSE messages are designed to be short, reliable, and high priority. GOOSE messages have additional
advantages over GSSE messages due to their support of VLAN (virtual LAN) and Ethernet priority tagging functionality.
The GSSE message structure contains space for 128 bit pairs representing digital point state information. The IEC 61850
specification provides 32 “DNA” bit pairs that represent the state of two pre-defined events and 30 user-defined events. All
remaining bit pairs are “UserSt” bit pairs, which are status bits representing user-definable events. The T60 implementation 5
provides 32 of the 96 available UserSt bit pairs.
The IEC 61850 specification includes features that are used to cope with the loss of communication between transmitting
and receiving devices. Each transmitting device will send a GSSE/GOOSE message upon a successful power-up, when
the state of any included point changes, or after a specified interval (the default update time) if a change-of-state has not
occurred. The transmitting device also sends a ‘hold time’ which is set greater than three times the programmed default
time required by the receiving device.
Receiving devices are constantly monitoring the communications network for messages they require, as recognized by the
identification of the originating device carried in the message. Messages received from remote devices include the mes-
sage time allowed to live. The receiving relay sets a timer assigned to the originating device to this time interval, and if it
has not received another message from this device at time-out, the remote device is declared to be non-communicating, so
it will use the programmed default state for all points from that specific remote device. If a message is received from a
remote device before the time allowed to live expires, all points for that device are updated to the states contained in the
message and the hold timer is restarted. The status of a remote device, where “Offline” indicates non-communicating, can
be displayed.
The remote input/output facility provides for 32 remote inputs and 64 remote outputs.
Likewise, the device ID that represents the IEC 61850 GSSE application ID name string sent as part of each GSSE mes-
sage is programmed in the SETTINGS PRODUCT SETUP COMMUNICATIONS IEC 61850 PROTOCOL GSSE/GOOSE
CONFIGURATION TRANSMISSION GSSE GSSE ID setting.
In T60 releases previous to 5.0x, these name strings were represented by the RELAY NAME setting.
Remote devices are available for setting purposes. A receiving relay must be programmed to capture messages from only
those originating remote devices of interest. This setting is used to select specific remote devices by entering (bottom row)
the exact identification (ID) assigned to those devices.
The REMOTE DEVICE 1 ETYPE APPID setting is only used with GOOSE messages; they are not applicable to GSSE mes-
sages. This setting identifies the Ethernet application identification in the GOOSE message. It should match the corre-
sponding settings on the sending device.
The REMOTE DEVICE 1 DATASET setting provides for the choice of the T60 fixed (DNA/UserSt) dataset (that is, containing
DNA and UserSt bit pairs), or one of the configurable datasets.
Note that the dataset for the received data items must be made up of existing items in an existing logical node. For this rea-
son, logical node GGIO3 is instantiated to hold the incoming data items. GGIO3 is not necessary to make use of the
received data. The remote input data item mapping takes care of the mapping of the inputs to remote input FlexLogic™
operands. However, GGIO3 data can be read by IEC 61850 clients.
Remote Inputs that create FlexLogic™ operands at the receiving relay are extracted from GSSE/GOOSE messages origi-
nating in remote devices. Each remote input can be selected from a list consisting of: DNA-1 through DNA-32, UserSt-1
through UserSt-32, and Dataset Item 1 through Dataset Item 32. The function of DNA inputs is defined in the IEC 61850
specification and is presented in the IEC 61850 DNA Assignments table in the Remote outputs section. The function of
UserSt inputs is defined by the user selection of the FlexLogic™ operand whose state is represented in the GSSE/GOOSE
message. A user must program a DNA point from the appropriate FlexLogic™ operand.
Remote input 1 must be programmed to replicate the logic state of a specific signal from a specific remote device for local
use. This programming is performed via the three settings shown above.
The REMOTE INPUT 1 ID setting allows the user to assign descriptive text to the remote input. The REMOTE IN 1 DEVICE setting
selects the remote device which originates the required signal, as previously assigned to the remote device via the setting
REMOTE DEVICE (16) ID (see the Remote devices section). The REMOTE IN 1 ITEM setting selects the specific bits of the
GSSE/GOOSE message required.
The REMOTE IN 1 DEFAULT STATE setting selects the logic state for this point if the local relay has just completed startup or
the remote device sending the point is declared to be non-communicating. The following choices are available:
• Setting REMOTE IN 1 DEFAULT STATE to “On” value defaults the input to logic 1.
• Setting REMOTE IN 1 DEFAULT STATE to “Off” value defaults the input to logic 0.
• Setting REMOTE IN 1 DEFAULT STATE to “Latest/On” freezes the input in case of lost communications. If the latest state is
not known, such as after relay power-up but before the first communication exchange, the input will default to logic 1.
When communication resumes, the input becomes fully operational.
• Setting REMOTE IN 1 DEFAULT STATE to “Latest/Off” freezes the input in case of lost communications. If the latest state is
not known, such as after relay power-up but before the first communication exchange, the input will default to logic 0.
When communication resumes, the input becomes fully operational.

ter.

Remote double-point status inputs are extracted from GOOSE messages originating in the remote device. Each remote
double point status input must be programmed to replicate the logic state of a specific signal from a specific remote device
for local use. This functionality is accomplished with the five remote double-point status input settings.
• REM DPS IN 1 ID: This setting assigns descriptive text to the remote double-point status input.
• REM DPS IN 1 DEV: This setting selects a remote device ID to indicate the origin of a GOOSE message. The range is
selected from the remote device IDs specified in the Remote devices section.
• REM DPS IN 1 ITEM: This setting specifies the required bits of the GOOSE message.
The configurable GOOSE dataset items must be changed to accept a double-point status item from a GOOSE dataset
(changes are made in the SETTINGS COMMUNICATION IEC 61850 PROTOCOL GSSE/GOOSE CONFIGURATION
RECEPTION CONFIGURABLE GOOSE CONFIGIGURABLE GOOSE 1(16) CONFIG GSE 1 DATASET ITEMS menus). Dataset
items configured to receive any of “GGIO3.ST.IndPos1.stV” to “GGIO3.ST.IndPos5.stV” will accept double-point status
information that will be decoded by the remote double-point status inputs configured to this dataset item.
The remote double point status is recovered from the received IEC 61850 dataset and is available as through the RemDPS
Ip 1 BAD, RemDPS Ip 1 INTERM, RemDPS Ip 1 OFF, and RemDPS Ip 1 ON FlexLogic™ operands. These operands can then be
used in breaker or disconnect control schemes.
Remote outputs (1 to 32) are FlexLogic™ operands inserted into GSSE/GOOSE messages that are transmitted to remote
devices on a LAN. Each digital point in the message must be programmed to carry the state of a specific FlexLogic™ oper-
and. The above operand setting represents a specific DNA function (as shown in the following table) to be transmitted.
Remote outputs 1 to 32 originate as GSSE/GOOSE messages to be transmitted to remote devices. Each digital point in the
message must be programmed to carry the state of a specific FlexLogic™ operand. The setting above is used to select the
operand which represents a specific UserSt function (as selected by the user) to be transmitted.
The following setting represents the time between sending GSSE/GOOSE messages when there has been no change of
state of any selected digital point. This setting is located in the PRODUCT SETUP COMMUNICATIONS IEC 61850 PROTO-
COL GSSE/GOOSE CONFIGURATION settings menu.

For more information on GSSE/GOOSE messaging, refer to Remote Inputs/Outputs Overview in the
Remote Devices section.
NOTE
5.8.9 RESETTING
Some events can be programmed to latch the faceplate LED event indicators and the target message on the display. Once
set, the latching mechanism will hold all of the latched indicators or messages in the set state after the initiating condition
has cleared until a RESET command is received to return these latches (not including FlexLogic™ latches) to the reset
state. The RESET command can be sent from the faceplate Reset button, a remote device via a communications channel,
or any programmed operand.
When the RESET command is received by the relay, two FlexLogic™ operands are created. These operands, which are
stored as events, reset the latches if the initiating condition has cleared. The three sources of RESET commands each cre-
ate the RESET OP FlexLogic™ operand. Each individual source of a RESET command also creates its individual operand
RESET OP (PUSHBUTTON), RESET OP (COMMS) or RESET OP (OPERAND) to identify the source of the command. The setting
shown above selects the operand that will create the RESET OP (OPERAND) operand.
a) DIRECT INPUTS
PATH: SETTINGS INPUTS/OUTPUTS DIRECT INPUTS DIRECT INPUT 1(32)
These settings specify how the direct input information is processed. The DIRECT INPUT 1 NAME setting allows the user to
assign a descriptive name to the direct input. The DIRECT INPUT 1 DEVICE ID represents the source of direct input 1. The
specified direct input is driven by the device identified here.
The DIRECT INPUT 1 BIT NUMBER is the bit number to extract the state for direct input 1. Direct Input 1 is driven by the bit
identified as DIRECT INPUT 1 BIT NUMBER. This corresponds to the direct output number of the sending device.
The DIRECT INPUT 1 DEFAULT STATE represents the state of the direct input when the associated direct device is offline. The
following choices are available:
• Setting DIRECT INPUT 1 DEFAULT STATE to “On” value defaults the input to Logic 1.
5
• Setting DIRECT INPUT 1 DEFAULT STATE to “Off” value defaults the input to Logic 0.
• Setting DIRECT INPUT 1 DEFAULT STATE to “Latest/On” freezes the input in case of lost communications. If the latest
state is not known, such as after relay power-up but before the first communication exchange, the input will default to
Logic 1. When communication resumes, the input becomes fully operational.
• Setting DIRECT INPUT 1 DEFAULT STATE to “Latest/Off” freezes the input in case of lost communications. If the latest
state is not known, such as after relay power-up but before the first communication exchange, the input will default to
Logic 0. When communication resumes, the input becomes fully operational.
b) DIRECT OUTPUTS
PATH: SETTINGS INPUTS/OUTPUTS DIRECT OUTPUTS DIRECT OUTPUT 1(32)
The DIRECT OUT 1 NAME setting allows the user to assign a descriptive name to the direct output. The DIR OUT 1 OPERAND is
the FlexLogic™ operand that determines the state of this direct output.
c) APPLICATION EXAMPLES

UR IED 1: DIRECT INPUT 5 DEVICE ID = “2” UR IED 2: DIRECT OUT 12 OPERAND = “Cont Ip 1 On”
DIRECT INPUT 5 BIT NUMBER = “12”
The Cont Ip 1 On operand of UR IED 2 is now available in UR IED 1 as DIRECT INPUT 5 ON.
EXAMPLE 2: INTERLOCKING BUSBAR PROTECTION
A simple interlocking busbar protection scheme can be accomplished by sending a blocking signal from downstream

In three-terminal applications, both the remote terminals must grant permission to trip. Therefore, at each terminal, direct

The “Latest/On” and “Latest/Off” values freeze the input in case of lost communications. If the latest state is not known,
such as after relay power-up but before the first communication exchange, then the input defaults to logic 1 for “Latest/On”
and logic 0 for “Latest/Off”.

As the following figure demonstrates, processing of the teleprotection inputs/outputs is dependent on the number of com-
munication channels and terminals. On two-terminal two-channel systems, they are processed continuously on each chan-
nel and mapped separately per channel. Therefore, to achieve redundancy, the user must assign the same operand on
both channels (teleprotection outputs at the sending end or corresponding teleprotection inputs at the receiving end). On
three-terminal two-channel systems, redundancy is achieved by programming signal re-transmittal in the case of channel
failure between any pair of relays.

PATH: SETTINGS INPUTS/OUTPUTS IEC 61850 GOOSE ANALOGS GOOSE ANALOG INPUT 1(32)
The IEC 61850 GOOSE analog inputs feature allows the transmission of analog values between any two UR-series
devices. The following settings are available for each GOOSE analog input.
• ANALOG 1 DEFAULT: This setting specifies the value of the GOOSE analog input when the sending device is offline
and the ANALOG 1 DEFAULT MODE is set to “Default Value”.This setting is stored as an IEEE 754 / IEC 60559 floating
point number. Because of the large range of this setting, not all possible values can be stored. Some values may be
rounded to the closest possible floating point number.
• ANALOG 1 DEFAULT MODE: When the sending device is offline and this setting is “Last Known”, the value of the
GOOSE analog input remains at the last received value. When the sending device is offline and this setting value is
“Default Value”, then the value of the GOOSE analog input is defined by the ANALOG 1 DEFAULT setting.
• GOOSE ANALOG 1 UNITS: This setting specifies a four-character alphanumeric string that can is used in the actual
values display of the corresponding GOOSE analog input value.
• GOOSE ANALOG 1 PU: This setting specifies the per-unit base factor when using the GOOSE analog input FlexAna-
log™ values in other T60 features, such as FlexElements™. The base factor is applied to the GOOSE analog input
FlexAnalog quantity to normalize it to a per-unit quantity. The base units are described in the following table.
The GOOSE analog input FlexAnalog™ values are available for use in other T60 functions that use FlexAnalog™ values.
PATH: SETTINGS INPUTS/OUTPUTS IEC 61850 GOOSE UINTEGERS GOOSE UINTEGER INPUT 1(16)
The IEC 61850 GOOSE uinteger inputs feature allows the transmission of FlexInteger™ values between any two UR-
series devices. The following settings are available for each GOOSE uinteger input.
• UINTEGER 1 DEFAULT: This setting specifies the value of the GOOSE uinteger input when the sending device is
offline and the UINTEGER 1 DEFAULT MODE is set to “Default Value”.This setting is stored as a 32-bit unsigned integer
number.
• UINTEGER 1 DEFAULT MODE: When the sending device is offline and this setting is “Last Known”, the value of the
GOOSE uinteger input remains at the last received value. When the sending device is offline and this setting value is
“Default Value”, then the value of the GOOSE uinteger input is defined by the UINTEGER 1 DEFAULT setting.
The GOOSE integer input FlexInteger™ values are available for use in other T60 functions that use FlexInteger™ values.
Hardware and software is provided to receive signals from external transducers and convert these signals into a digital for-
mat for use as required. The relay will accept inputs in the range of –1 to +20 mA DC, suitable for use with most common
transducer output ranges; all inputs are assumed to be linear over the complete range. Specific hardware details are con-
tained in chapter 3.
Before the dcmA input signal can be used, the value of the signal measured by the relay must be converted to the range
5 and quantity of the external transducer primary input parameter, such as DC voltage or temperature. The relay simplifies
this process by internally scaling the output from the external transducer and displaying the actual primary parameter.
dcmA input channels are arranged in a manner similar to CT and VT channels. The user configures individual channels
with the settings shown here.
The channels are arranged in sub-modules of two channels, numbered from 1 through 8 from top to bottom. On power-up,
the relay will automatically generate configuration settings for every channel, based on the order code, in the same general
manner that is used for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8 inclu-
sive, which is used as the channel number. The relay generates an actual value for each available input channel.
Settings are automatically generated for every channel available in the specific relay as shown above for the first channel of
a type 5F transducer module installed in slot F.
The function of the channel may be either “Enabled” or “Disabled”. If “Disabled”, no actual values are created for the chan-
nel. An alphanumeric “ID” is assigned to each channel; this ID will be included in the channel actual value, along with the
programmed units associated with the parameter measured by the transducer, such as volts, °C, megawatts, etc. This ID is
also used to reference the channel as the input parameter to features designed to measure this type of parameter. The
DCMA INPUT F1 RANGE setting specifies the mA DC range of the transducer connected to the input channel.
The DCMA INPUT F1 MIN VALUE and DCMA INPUT F1 MAX VALUE settings are used to program the span of the transducer in pri-
mary units. For example, a temperature transducer might have a span from 0 to 250°C; in this case the DCMA INPUT F1 MIN
VALUE value is “0” and the DCMA INPUT F1 MAX VALUE value is “250”. Another example would be a watts transducer with a
span from –20 to +180 MW; in this case the DCMA INPUT F1 MIN VALUE value would be “–20” and the DCMA INPUT F1 MAX
VALUE value “180”. Intermediate values between the min and max values are scaled linearly.
Hardware and software is provided to receive signals from external resistance temperature detectors and convert these
signals into a digital format for use as required. These channels are intended to be connected to any of the RTD types in
common use. Specific hardware details are contained in chapter 3.
RTD input channels are arranged in a manner similar to CT and VT channels. The user configures individual channels with
the settings shown here.
The channels are arranged in sub-modules of two channels, numbered from 1 through 8 from top to bottom. On power-up,
the relay will automatically generate configuration settings for every channel, based on the order code, in the same general
manner that is used for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8 inclu-
sive, which is used as the channel number. The relay generates an actual value for each available input channel.
Settings are automatically generated for every channel available in the specific relay as shown above for the first channel of
a type 5C transducer module installed in the first available slot.
The function of the channel may be either “Enabled” or “Disabled”. If “Disabled”, there will not be an actual value created for
the channel. An alphanumeric ID is assigned to the channel; this ID will be included in the channel actual values. It is also 5
used to reference the channel as the input parameter to features designed to measure this type of parameter. Selecting the
type of RTD connected to the channel configures the channel.
Actions based on RTD overtemperature, such as trips or alarms, are done in conjunction with the FlexElements™ feature.
In FlexElements™, the operate level is scaled to a base of 100°C. For example, a trip level of 150°C is achieved by setting
the operate level at 1.5 pu. FlexElement™ operands are available to FlexLogic™ for further interlocking or to operate an
output contact directly.

MESSAGE See page 5-277.
It is recommended to use the T60 to configure the RRTD parameters. If the RRTDPC software is used to change the RRTD
settings directly (the application and type settings), then one of the following two operations is required for changes to be
reflected in the T60.
• Cycle power to T60.
• Break then re-establish the communication link between the RRTD unit and the T60. This will cause the RRTD COMM
FAIL operand to be asserted then de-asserted.
The remote RTD inputs convert values of input resistance into temperature for further operations. These inputs are
intended to be connected to any of the RTD types in common use. Specific hardware details are contained in chapter 3.
On power up, the T60 reads and saves all application and type settings from the RRTD. This synchronizes the RRTD and
T60. Any changes to RRTD settings (function, application, or type) from the T60 interface are immediately reflected in the
RRTD. The following rules are followed.
• If the RRTD 1 FUNCTION setting is “Enabled”, then the RRTD 1 APPLICATION setting value will be written to RRTD device.
• If the RRTD 1 FUNCTION setting is “Disabled”, then RRTD1 APPLICATION setting value is set as “None”.
• If the RRTD 1 APPLICATION or RRTD 1 TYPE settings are changes, then these settings are immediately written to the
RRTD device.
• If the RRTD 1 APPLICATION setting is “Group 1” or “Group 2”, then a value of “Other” is written to the RRTD device.
An RRTD actual value of –43°C implies that the RRTD 1 FUNCTION setting is “Enabled” but the corresponding RRTD 1 APPLI-
CATION setting is “None”.
If the RRTD communication link with the T60 is broken, then the last temperature actual values are retained until the RRTD
communication failure is detected. When this occurs, a RRTD COMM FAILURE self-test alarm and target message is gen-
erated, and an event is logged in the event recorder and the temperature actual values reset to 0. When the link is re-estab-
lished, the RRTD 1 APPLICATION and RRTD 1 TYPE settings are read from the RRTD to re-synchronize the device.
• RRTD 1 FUNCTION: This setting enables and disables the remote RTD. If set to “Disabled”, no actual value is created
for the remote RTD.
• RRTD 1 ID: This setting is used to assign alphanumeric ID is assigned to the remote RTD. This ID will be included in
the remote RTD actual values. It is also used to reference the remote RTD input to features using the remote RTD.
• RRTD 1 TYPE: This setting specifies the remote RTD type. Four different RTD types are available: 100 Nickel, 10
Copper, 100 Platinum, and 120 Nickel.
The RRTD converts resistance to temperature as per the values in the following table. The T60 reads the RTD temper-
atures from the RRTD once every five seconds and applies protection accordingly. The RRTDs can be used to provide
RTD bias in the existing thermal model.
An RRTD open condition is detected when actual RRTD resistance is greater than 1000 ohms and RRTD open is dis-
played as “250°C” in the T60.
An RRTD short condition is detected when actual RRTD temperature is less than –40°C and RRTD short is displayed
as is “–50°C”. in the T60.
• RRTD 1 APPLICATION: This setting allows each remote RTD to be assigned to a group application. This is useful for
applications that require group measurement for voting. A value of “None” specifies that the remote RTD will operate
individually and not part of any RTD group. All remote RTDs programmed to “Stator” are used for RTD biasing of the
T60 thermal model. Common groups are provided for rotating machines applications such as ambient, bearing, group
1, or group 2. If the REMOTE RTD 1 TRIP VOTING setting value is “Group”, then it is allowed to issue a trip if N – 1 RTDs
from the same group also pick up, where N is the number of enabled RTDs from the group.
• RRTD 1 ALARM TEMPERATURE: This setting specifies the temperature pickup level for the alarm stage. The range
of 1 to 200°C differs from the existing RTD settings to correspond to the range of the RRTD unit.
• RRTD 1 ALARM PKP DELAY: This setting specifies time delay for the alarm stage until the output can be asserted.
The range of 5 to 600 seconds differs from the existing RTD settings to correspond to the range of the RRTD unit.
• RRTD 1 TRIP TEMPERATURE: This setting specifies the temperature pickup level for the trip stage. The range of 1 to
200°C differs from the existing RTD settings to correspond to the range of the RRTD unit.
• RRTD 1 TRIP PKP DELAY: This setting specifies time delay for the trip stage until the output can be asserted. The
range of 5 to 600 seconds differs from the existing RTD settings to correspond to the range of the RRTD unit.
• RRTD 1 TRIP RST DELAY: This setting specifies the reset delay to seal-in the trip signal.
• RRTD 1 TRIP VOTING: This setting allows securing trip signal by voting with other RTDs. A value of “None” indicates
that element operates individually and no voting takes place.
A value of “Group” indicates that element is allowed to issue a trip if N – 1 of other RTDs of the same group pick up as
well (where N is the number of enabled RTDs from the group). For example, if three RTDs are assigned to the same
group, there should be at least one additional RTD of the same group picked up to issue a trip command.
The “Remote RTD 1” through “Remote RTD 12” values indicate that element is allowed to issue a trip if the corre- 5
sponding peer RTD is also picked up.
• RRTD 1 OPEN: This setting allows monitoring an open remote RTD sensor circuit. If this functionality is not required,
then a value of “None” will disable monitoring and assertion of output operands.
If set to “Alarm”, the monitor will set an alarm when a broken sensor is detected.
If set to “Block”, the monitor will set an alarm and simultaneously block remote RTD operation when a broken sensor is
detected.
If targets are enabled, a message will appear on the display identifying the broken RTD. If this feature is used, it is rec-
ommended that the alarm be programmed as latched so that intermittent RTDs are detected and corrective action may
be taken.
• RRTD 1 BLOCK: This setting is used to block remote RTD operation.

Hardware and software is provided to generate dcmA signals that allow interfacing with external equipment. Specific hard-
ware details are contained in chapter 3. The dcmA output channels are arranged in a manner similar to transducer input or
CT and VT channels. The user configures individual channels with the settings shown below.
The channels are arranged in sub-modules of two channels, numbered 1 through 8 from top to bottom. On power-up, the
relay automatically generates configuration settings for every channel, based on the order code, in the same manner used
for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8 inclusive, which is used as
the channel number.
Both the output range and a signal driving a given output are user-programmable via the following settings menu (an exam-
ple for channel M5 is shown).
The relay checks the driving signal (x in equations below) for the minimum and maximum limits, and subsequently re-
scales so the limits defined as MIN VAL and MAX VAL match the output range of the hardware defined as RANGE. The follow-
ing equation is applied:
The feature is intentionally inhibited if the MAX VAL and MIN VAL settings are entered incorrectly, e.g. when MAX VAL – MIN
VAL< 0.1 pu. The resulting characteristic is illustrated in the following figure.

The base unit for power (refer to the FlexElements section in this chapter for additional details) is:
P BASE = 115 V 120 1.2 kA = 16.56 MW (EQ 5.58)
The minimum and maximum power values to be monitored (in pu) are:
20.65 MW = – 1.247 pu, maximum power = 20.65 MW- = 1.247 pu
minimum power = –------------------------------ -------------------------- (EQ 5.59)

The following settings should be entered:
DCMA OUTPUT H1 SOURCE: “SRC 1 P”
DCMA OUTPUT H1 RANGE: “–1 to 1 mA”
DCMA OUTPUT H1 MIN VAL: “–1.247 pu”
DCMA OUTPUT H1 MAX VAL: “1.247 pu”
With the above settings, the output will represent the power with the scale of 1 mA per 20.65 MW. The worst-case error for
this application can be calculated by superimposing the following two sources of error:
• ±0.5% of the full scale for the analog output module, or 0.005 1 – – 1 20.65 MW = 0.207 MW
• ±1% of reading error for the active power at power factor of 0.9
For example at the reading of 20 MW, the worst-case error is 0.01 20 MW + 0.207 MW = 0.407 MW.
EXAMPLE: CURRENT MONITORING
The phase A current (true RMS value) is to be monitored via the H2 current output working with the range from 4 to 20 mA.
The CT ratio is 5000:5 and the maximum load current is 4200 A. The current should be monitored from 0 A upwards, allow-
ing for 50% overload.
The base unit for current (refer to the FlexElements section in this chapter for additional details) is:
I BASE = 5 kA (EQ 5.61)
The minimum and maximum power values to be monitored (in pu) are:
The worst-case error for this application could be calculated by superimposing the following two sources of error:
• ±0.5% of the full scale for the analog output module, or 0.005 20 – 4 6.3 kA = 0.504 kA
• ±0.25% of reading or ±0.1% of rated (whichever is greater) for currents between 0.1 and 2.0 of nominal
For example, at the reading of 4.2 kA, the worst-case error is max(0.0025 4.2 kA, 0.001 5 kA) + 0.504 kA = 0.515 kA.
EXAMPLE: VOLTAGE MONITORING
A positive-sequence voltage on a 400 kV system measured via source 2 is to be monitored by the dcmA H3 output with a
range of 0 to 1 mA. The VT secondary setting is 66.4 V, the VT ratio setting is 6024, and the VT connection setting is
“Delta”. The voltage should be monitored in the range from 70% to 110% of nominal.
The minimum and maximum positive-sequence voltages to be monitored are:
400 kV 400 kV

The base unit for voltage (refer to the FlexElements section in this chapter for additional details) is:
The minimum and maximum voltage values to be monitored (in pu) are:
minimum voltage = 161.66 kV- = 0.404 pu, maximum voltage = 254.03 kV- = 0.635 pu
-------------------------- -------------------------- (EQ 5.65)
400 kV 400 kV
The following settings should be entered:
DCMA OUTPUT H3 SOURCE: “SRC 2 V_1 mag”
DCMA OUTPUT H3 RANGE: “0 to 1 mA”
DCMA OUTPUT H3 MIN VAL: “0.404 pu”
DCMA OUTPUT H3 MAX VAL: “0.635 pu”
The limit settings differ from the expected 0.7 pu and 1.1 pu because the relay calculates the positive-sequence quantities
scaled to the phase-to-ground voltages, even if the VTs are connected in “Delta” (refer to the Metering conventions section
in chapter 6), while at the same time the VT nominal voltage is 1 pu for the settings. Consequently the settings required in
this example differ from naturally expected by the factor of 3 .
The worst-case error for this application could be calculated by superimposing the following two sources of error:
• ±0.5% of the full scale for the analog output module, or 0.005 1 – 0 254.03 kV = 1.27 kV
• ±0.5% of reading
For example, under nominal conditions, the positive-sequence reads 230.94 kV and the worst-case error is
0.005 x 230.94 kV + 1.27 kV = 2.42 kV.
The T60 provides a test facility to verify the functionality of contact inputs and outputs, some communication channels and
the phasor measurement unit (where applicable), using simulated conditions. The test mode is indicated on the relay face-
plate by a Test Mode LED indicator.
The test mode may be in any of three states: disabled, isolated, or forcible.
In the “Disabled” mode, T60 operation is normal and all test features are disabled.
In the “Isolated” mode, the T60 is prevented from performing certain control actions, including tripping via contact outputs.
All relay contact outputs, including latching outputs, are disabled. Channel tests and phasor measurement unit tests remain
usable on applicable UR-series models.
In the “Forcible” mode, the operand selected by the TEST MODE FORCING setting controls the relay inputs and outputs. If the
test mode is forcible, and the operand assigned to the TEST MODE FORCING setting is “Off”, the T60 inputs and outputs oper-
ate normally. If the test mode is forcible, and the operand assigned to the TEST MODE FORCING setting is “On”, the T60 con-
tact inputs and outputs are forced to the values specified in the following sections. Forcing may be controlled by manually
changing the operand selected by the TEST MODE FORCING setting between on and off, or by selecting a user-programma-
ble pushbutton, contact input, or communication-based input operand. Channel tests and phasor measurement unit tests
When in “Forcible” mode, the operand selected by the TEST MODE FORCING setting dictates further response of the T60 to
testing conditions. To force contact inputs and outputs through relay settings, set TEST MODE FORCING to “On”. To force con-
tact inputs and outputs through a user-programmable condition, such as FlexLogic™ operand (pushbutton, digital input,
communication-based input, or a combination of these), set TEST MODE FORCING to the desired operand. The contact input
or output is forced when the selected operand assumes a logic 1 state.
The T60 remains fully operational in test mode, allowing for various testing procedures. In particular, the protection and
control elements, FlexLogic™, and communication-based inputs and outputs function normally.
The only difference between the normal operation and the test mode is the behavior of the input and output contacts. The
contact inputs can be forced to report as open or closed or remain fully operational, whereas the contact outputs can be
forced to open, close, freeze, or remain fully operational. The response of the digital input and output contacts to the test
mode is programmed individually for each input and output using the force contact inputs and force contact outputs test
functions described in the following sections.
The test mode state is indicated on the relay faceplate by a combination of the Test Mode LED indicator, the In-Service LED
indicator, and by the critical fail relay, as shown in the following table.
The TEST MODE FUNCTION setting can only be changed by a direct user command. Following a restart, power up, settings
upload, or firmware upgrade, the test mode will remain at the last programmed value. This allows a T60 that has been
placed in isolated mode to remain isolated during testing and maintenance activities. On restart, the TEST MODE FORCING
setting and the force contact input and force contact output settings all revert to their default states.
The relay digital inputs (contact inputs) could be pre-programmed to respond to the test mode in the following ways:
• If set to “Disabled”, the input remains fully operational. It is controlled by the voltage across its input terminals and can
be turned on and off by external circuitry. This value should be selected if a given input must be operational during the
test. This includes, for example, an input initiating the test, or being a part of a user pre-programmed test sequence.
• If set to “Open”, the input is forced to report as opened (Logic 0) for the entire duration of the test mode regardless of
the voltage across the input terminals.
• If set to “Closed”, the input is forced to report as closed (Logic 1) for the entire duration of the test mode regardless of
the voltage across the input terminals.
The force contact inputs feature provides a method of performing checks on the function of all contact inputs. Once
enabled, the relay is placed into test mode, allowing this feature to override the normal function of contact inputs. The Test
Mode LED will be on, indicating that the relay is in test mode. The state of each contact input may be programmed as “Dis-
abled”, “Open”, or “Closed”. All contact input operations return to normal when all settings for this feature are disabled.
The relay contact outputs can be pre-programmed to respond to the test mode.
If set to “Disabled”, the contact output remains fully operational. If operates when its control operand is logic 1 and will
resets when its control operand is logic 0. If set to “Energized”, the output will close and remain closed for the entire dura-
tion of the test mode, regardless of the status of the operand configured to control the output contact. If set to “De-ener-
gized”, the output will open and remain opened for the entire duration of the test mode regardless of the status of the
operand configured to control the output contact. If set to “Freeze”, the output retains its position from before entering the
test mode, regardless of the status of the operand configured to control the output contact.
These settings are applied two ways. First, external circuits may be tested by energizing or de-energizing contacts. Sec-
ond, by controlling the output contact state, relay logic may be tested and undesirable effects on external circuits avoided.
Example 1: Initiating test mode through user-programmable pushbutton 1
5 For example, the test mode can be initiated from user-programmable pushbutton 1. The pushbutton will be programmed as
“Latched” (pushbutton pressed to initiate the test, and pressed again to terminate the test). During the test, digital input 1
should remain operational, digital inputs 2 and 3 should open, and digital input 4 should close. Also, contact output 1 should
freeze, contact output 2 should open, contact output 3 should close, and contact output 4 should remain fully operational.
The required settings are shown below.
To enable user-programmable pushbutton 1 to initiate the test mode, make the following changes in the SETTINGS
TESTING TEST MODE menu: TEST MODE FUNCTION: “Enabled” and TEST MODE INITIATE: “PUSHBUTTON 1 ON”
Make the following changes to configure the contact inputs and outputs. In the SETTINGS TESTING FORCE CONTACT
INPUTS and FORCE CONTACT OUTPUTS menus, set:
FORCE Cont Ip 1: “Disabled”, FORCE Cont Ip 2: “Open”, FORCE Cont Ip 3: “Open”, and FORCE Cont Ip 4: “Closed”
FORCE Cont Op 1: “Freeze”, FORCE Cont Op 2: “De-energized”, FORCE Cont Op 3: “Energized”,
and FORCE Cont Op 4: “Disabled”
Example 2: Initiating a test from user-programmable pushbutton 1 or through remote input 1
In this example, the test can be initiated locally from user-programmable pushbutton 1 or remotely through remote input 1.
Both the pushbutton and the remote input will be programmed as “Latched”. Write the following FlexLogic™ equation:
Set the user-programmable pushbutton as latching by changing SETTINGS PRODUCT SETUP USER-PROGRAMMABLE
PUSHBUTTONS USER PUSHBUTTON 1 PUSHBUTTON 1 FUNCTION to “Latched”. To enable either pushbutton 1 or remote
input 1 to initiate the Test mode, make the following changes in the SETTINGS TESTING TEST MODE menu:
TEST MODE FUNCTION: “Enabled” and TEST MODE INITIATE: “VO1”
The relay must be in test mode to use the PMU test mode. That is, the TESTING TEST MODE FUNCTION setting must be
“Enabled” and the TESTING TEST MODE INITIATE initiating signal must be “On”.
During the PMU test mode, the physical channels (VA, VB, VC, VX, IA, IB, IC, and IG), frequency, and rate of change of fre-
quency are substituted with user values, while the symmetrical components are calculated from the physical channels. The
test values are not explicitly marked in the outgoing data frames. When required, it is recommended to use the user-pro-
grammable digital channels to signal the C37.118 client that test values are being sent in place of the real measurements.

b) PHASE ANGLES
All phasors calculated by UR-series relays and used for protection, control and metering functions are rotating phasors that
maintain the correct phase angle relationships with each other at all times.
For display and oscillography purposes, all phasor angles in a given relay are referred to an AC input channel pre-selected
by the SETTINGS SYSTEM SETUP POWER SYSTEM FREQUENCY AND PHASE REFERENCE setting. This setting
defines a particular AC signal source to be used as the reference.
The relay will first determine if any “Phase VT” bank is indicated in the source. If it is, voltage channel VA of that bank is
used as the angle reference. Otherwise, the relay determines if any “Aux VT” bank is indicated; if it is, the auxiliary voltage
channel of that bank is used as the angle reference. If neither of the two conditions is satisfied, then two more steps of this
hierarchical procedure to determine the reference signal include “Phase CT” bank and “Ground CT” bank.
If the AC signal pre-selected by the relay upon configuration is not measurable, the phase angles are not referenced. The
phase angles are assigned as positive in the leading direction, and are presented as negative in the lagging direction, to
more closely align with power system metering conventions. This is illustrated below.

c) SYMMETRICAL COMPONENTS
The UR-series of relays calculate voltage symmetrical components for the power system phase A line-to-neutral voltage,
and symmetrical components of the currents for the power system phase A current. Owing to the above definition, phase
angle relations between the symmetrical currents and voltages stay the same irrespective of the connection of instrument
transformers. This is important for setting directional protection elements that use symmetrical voltages.
For display and oscillography purposes the phase angles of symmetrical components are referenced to a common refer-
ence as described in the previous sub-section.

transients.
The metered current harmonics values are displayed in this menu. The "SRC 1" text will be replaced by whatever name

6 The event records menu shows the contextual data associated with up to the last 1024 events, listed in chronological order
from most recent to oldest. If all 1024 event records have been filled, the oldest record will be removed as a new record is
added. Each event record shows the event identifier/sequence number, cause, and date/time stamp associated with the
event trigger. Refer to the COMMANDS CLEAR RECORDS menu for clearing event records.
6.4.3 OSCILLOGRAPHY
This menu allows the user to view the number of triggers involved and number of oscillography traces available. The
CYCLES PER RECORD value is calculated to account for the fixed amount of data storage for oscillography. See the Oscillog-
raphy section of chapter 5 for additional details.
A trigger can be forced here at any time by setting “Yes” to the FORCE TRIGGER? command. Refer to the COMMANDS
CLEAR RECORDS menu for information on clearing the oscillography records.
The OLDEST SAMPLE TIME represents the time at which the oldest available samples were taken. It will be static until the log
gets full, at which time it will start counting at the defined sampling rate. The NEWEST SAMPLE TIME represents the time the
most recent samples were taken. It counts up at the defined sampling rate. If the data logger channels are defined, then
both values are static.
Refer to the COMMANDS CLEAR RECORDS menu for clearing data logger records.
The number of triggers applicable to the phasor measurement unit recorder is indicated by the NUMBER OF TRIGGERS value.

The PERFORM LAMPTEST command turns on all faceplate LEDs and display pixels for a short duration. The UPDATE
ORDER CODE command causes the relay to scan the backplane for the hardware modules and update the order code to
match. If an update occurs, the following message is shown.
UPDATING...
PLEASE WAIT
There is no impact if there have been no changes to the hardware modules. When an update does not occur, the ORDER
CODE NOT UPDATED message will be shown.
The SERVICE COMMAND is used to perform specific T60 service actions. Presently, there is only one service action available.
Code “101” is used to clear factory diagnostic information stored in the non-volatile memory. If a code other than “101” is
entered, the command will be ignored and no actions will be taken. Various self-checking diagnostics are performed in the
background while the T60 is running, and diagnostic information is stored on the non-volatile memory from time to time
based on the self-checking result. Although the diagnostic information is cleared before the T60 is shipped from the factory,
the user may want to clear the diagnostic information for themselves under certain circumstances. For example, it may be
desirable to clear diagnostic information after replacement of hardware. Once the diagnostic information is cleared, all self-
checking variables are reset to their initial state and diagnostics will restart from scratch.
This feature allows pre-scheduling a PMU measurement at a specific point in time. This functionality can be used to test for
accuracy of the PMU, and for manual collection of synchronized measurements through the system, as explained below.
When enabled, the function continuously compares the present time with the pre-set PMU ONE-SHOT TIME. When the two
times match, the function compares the present sequence number of the measured synchrophasors with the pre-set PMU
ONE-SHOT SEQUENCE NUMBER. When the two numbers match, the function freezes the synchrophasor actual values and
the corresponding protocol data items for 30 seconds. This allows manual read-out of the synchrophasor values for the pre-
set time and pre-set sequence number (via the faceplate display, supported communication protocols such as Modbus or
DNP, and the EnerVista UR Setup software).
When freezing the actual values the function also asserts a PMU ONE-SHOT OP FlexLogic™ operand. This operand may be
configured to drive an output contact and trigger an external measuring device such as a digital scope with the intent to ver-
ify the accuracy of the PMU under test.
With reference to the figure below, the PMU one-shot function (when enabled) controls three FlexLogic™ operands:
• The PMU ONE-SHOT EXPIRED operand indicates that the one-shot operation has been executed, and the present time
is at least 30 seconds past the scheduled one-shot time.
• The PMU ONE-SHOT PENDING operand indicates that the one-shot operation is pending; that is, the present time is
before the scheduled one-shot time.
• The PMU ONE-SHOT OP operand indicates the one-shot operation and remains asserted for 30 seconds afterwards.
When the function is disabled, all three operands are de-asserted. The one-shot function applies to all logical PMUs of a
given T60 relay.
7 respect to the timing reference provided to the PMU and not to the absolute UTC time. Therefore a simple IRIG-B genera-
tor could be used instead. Also, the test set does not have to support GPS synchronization. Any stable signal source can
be used. If both the PMU under test and the test set use the timing reference, they should be driven from the same IRIG-B
signal: either the same GPS receiver or IRIG-B generator. Otherwise, the setpoints of the test set and the PMU measure-
ments should not be compared as they are referenced to different time scales.

COLLECTING SYNCHRONIZED MEASUREMENTS AD HOC:
The one-shot feature can be used for ad hoc collection of synchronized measurements in the network. Two or more PMU
can be pre-scheduled to freeze their measurements at the same time. When frozen the measurements could be collected
using EnerVista UR Setup or a protocol client.

Two levels of password security are provided via the ACCESS LEVEL setting: command and setting. The factory service level
is not available and intended for factory use only.
The following operations are under command password supervision:
• Changing the state of virtual inputs.
• Clearing the event records.
• Clearing the oscillography records.
• Changing the date and time.
• Clearing energy records.
• Clearing the data logger.
• Clearing the user-programmable pushbutton states.
The following operations are under setting password supervision:
• Changing any setting.
• Test mode operation.
The command and setting passwords are defaulted to “0” when the relay is shipped from the factory. When a password is
set to “0”, the password security feature is disabled.
The T60 supports password entry from a local or remote connection.
Local access is defined as any access to settings or commands via the faceplate interface. This includes both keypad entry
and the through the faceplate RS232 port. Remote access is defined as any access to settings or commands via any rear
communications port. This includes both Ethernet and RS485 connections. Any changes to the local or remote passwords
enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the correspond-
ing connection password. If the connection is to the back of the T60, the remote password must be used. If the connection
is to the RS232 port of the faceplate, the local password must be used.
The PASSWORD ACCESS EVENTS settings allows recording of password access events in the event recorder.
The local setting and command sessions are initiated by the user through the front panel display and are disabled either by
the user or by timeout (via the setting and command level access timeout settings). The remote setting and command ses-
sions are initiated by the user through the EnerVista UR Setup software and are disabled either by the user or by timeout.
The state of the session (local or remote, setting or command) determines the state of the following FlexLogic™ operands.
• ACCESS LOC SETG OFF: Asserted when local setting access is disabled.
• ACCESS LOC SETG ON: Asserted when local setting access is enabled.
• ACCESS LOC CMND OFF: Asserted when local command access is disabled.
•
•
ACCESS LOC CMND ON: Asserted when local command access is enabled.
ACCESS REM SETG OFF: Asserted when remote setting access is disabled.

• ACCESS REM SETG ON: Asserted when remote setting access is enabled.
• ACCESS REM CMND OFF: Asserted when remote command access is disabled.
• ACCESS REM CMND ON: Asserted when remote command access is enabled.
The appropriate events are also logged in the Event Recorder as well. The FlexLogic™ operands and events are updated
every five seconds.
A command or setting write operation is required to update the state of all the remote and local security operands
shown above.

The dual permission security access feature provides a mechanism for customers to prevent unauthorized or unintended
upload of settings to a relay through the local or remote interfaces interface.
The following settings are available through the local (front panel) interface only.
• LOCAL SETTING AUTH: This setting is used for local (front panel or RS232 interface) setting access supervision.
Valid values for the FlexLogic™ operands are either “On” (default) or any physical “Contact Input ~~ On” value.
If this setting is “On“, then local setting access functions as normal; that is, a local setting password is required. If this
setting is any contact input on FlexLogic™ operand, then the operand must be asserted (set as on) prior to providing
the local setting password to gain setting access.
If setting access is not authorized for local operation (front panel or RS232 interface) and the user attempts to obtain
setting access, then the UNAUTHORIZED ACCESS message is displayed on the front panel.
• REMOTE SETTING AUTH: This setting is used for remote (Ethernet or RS485 interfaces) setting access supervision.
If this setting is “On” (the default setting), then remote setting access functions as normal; that is, a remote password is
required). If this setting is “Off”, then remote setting access is blocked even if the correct remote setting password is
provided. If this setting is any other FlexLogic™ operand, then the operand must be asserted (set as on) prior to pro-
viding the remote setting password to gain setting access.
• ACCESS AUTH TIMEOUT: This setting represents the timeout delay for local setting access. This setting is applicable
when the LOCAL SETTING AUTH setting is programmed to any operand except “On”. The state of the FlexLogic™ oper-
and is continuously monitored for an off-to-on transition. When this occurs, local access is permitted and the timer pro-
grammed with the ACCESS AUTH TIMEOUT setting value is started. When this timer expires, local setting access is
immediately denied. If access is permitted and an off-to-on transition of the FlexLogic™ operand is detected, the time-
out is restarted. The status of this timer is updated every 5 seconds.
The following settings are available through the remote (EnerVista UR Setup) interface only. Select the Settings > Product
Setup > Security menu item to display the security settings window.
The Remote Settings Authorization setting is used for remote (Ethernet or RS485 interfaces) setting access supervision.
If this setting is “On” (the default setting), then remote setting access functions as normal; that is, a remote password is
required). If this setting is “Off”, then remote setting access is blocked even if the correct remote setting password is pro-
vided. If this setting is any other FlexLogic™ operand, then the operand must be asserted (set as on) prior to providing the
remote setting password to gain setting access.
The Access Authorization Timeout setting represents the timeout delay remote setting access. This setting is applicable
when the Remote Settings Authorization setting is programmed to any operand except “On” or “Off”. The state of the
FlexLogic™ operand is continuously monitored for an off-to-on transition. When this occurs, remote setting access is per-
mitted and the timer programmed with the Access Authorization Timeout setting value is started. When this timer
expires, remote setting access is immediately denied. If access is permitted and an off-to-on transition of the FlexLogic™
operand is detected, the timeout is restarted. The status of this timer is updated every 5 seconds.
Setting file templates simplify the configuration and commissioning of multiple relays that protect similar assets. An exam-
ple of this is a substation that has ten similar feeders protected by ten UR-series F60 relays.
In these situations, typically 90% or greater of the settings are identical between all devices. The templates feature allows
engineers to configure and test these common settings, then lock them so they are not available to users. For example,
these locked down settings can be hidden from view for field engineers, allowing them to quickly identify and concentrate
on the specific settings.
The remaining settings (typically 10% or less) can be specified as editable and be made available to field engineers install-
ing the devices. These will be settings such as protection element pickup values and CT and VT ratios.
The settings template mode allows the user to define which settings will be visible in EnerVista UR Setup. Settings tem-
plates can be applied to both settings files (settings file templates) and online devices (online settings templates). The func-
tionality is identical for both purposes.
The settings template feature requires that both the EnerVista UR Setup software and the T60 firmware are at ver-
sions 5.40 or higher.
NOTE
The software will prompt for a template password. This password is required to use the template feature and must be
at least four characters in length.

A traceability feature for settings files allows the user to quickly determine if the settings in a T60 device have been
changed since the time of installation from a settings file. When a settings file is transfered to a T60 device, the date, time,
and serial number of the T60 are sent back to EnerVista UR Setup and added to the settings file on the local PC. This infor-
mation can be compared with the T60 actual values at any later date to determine if security has been compromised.
The traceability information is only included in the settings file if a complete settings file is either transferred to the T60
device or obtained from the T60 device. Any partial settings transfers by way of drag and drop do not add the traceability
information to the settings file.
The serial number of the UR-series device and the file transfer
date are added to the settings file when settings files
are transferred to the device.
1. The transfer date of a setting file written to a T60 is logged in the relay and can be viewed via EnerVista UR Setup or
the front panel display. Likewise, the transfer date of a setting file saved to a local PC is logged in EnerVista UR Setup.
2. Comparing the dates stored in the relay and on the settings file at any time in the future will indicate if any changes
have been made to the relay configuration since the settings file was saved.

The EnerVista security management system is a role-based access control (RBAC) system that allows a security adminis-
trator to easily manage the security privileges of multiple users. This allows for access control of URPlus-series devices by
multiple personnel within a substation and conforms to the principles of RBAC as defined in ANSI INCITS 359-2004. The
EnerVista security management system is disabled by default to allow the administrator direct access to the EnerVista soft-
ware after installation. It is recommended that security be enabled before placing the device in service.
The EnerVista security management system is disabled by default. This allows access to the device immediately after

a) OVERVIEW
The following commissioning tests are organized in two parts: general procedures for testing points of the differential-
restraint characteristics, and examples of the percent differential element response, based on different transformer configu-
rations and fault current distribution. The following tests can be performed by using either 2 or 3 individually adjustable cur-
rents, and do not require additional specialized equipment.
PREPARATION:
1. Select a 0° or 180° transformer phase shift and identical winding connection type into the relay.
2. Select the “Not Within Zone” setting value for each winding grounding setting.
3. Select and set the CT ratios for each winding.
4. Calculate the magnitude compensation factors M[1] and M[2] for each winding.
5. Enable the Transformer Percent Differential element, and enter the required test settings to shape the differential
restraint characteristic.
6. Connect the relay test set to inject x current (Ix) into the Winding 1 Phase A CT input, and y current (IY) into the Wind-
ing 2 Phase A CT input.
TESTING:
The tests of the differential restraint characteristic verify the minimum pickup point, the intersection point of Breakpoint 1
and Slope 1, and the intersection point of Breakpoint 2 and Slope 2.
For simplicity, enter the following settings for each winding:
SYSTEM SETUP TRANSFORMER WINDING 1(4) WINDING 1(4) CONNECTION: “Wye”
SYSTEM SETUP TRANSFORMER WINDING 1(4) WINDING 1(4) GROUNDING: “Not Within Zone”
SYSTEM SETUP TRANSFORMER WINDING 2(4) WINDING 2(4) ANGLE WRT WINDING 1: “0°”
If the power transformer phase shift is 0°, the two currents to be injected to the relay should be 180° apart. The 180° phase
shift results from the inversion of the field CT, as their positive marks are away from the protected transformer terminals and
are connected to the positively marked terminals on the relay.
b) MINIMUM PICKUP
Inject current (Ix) into Winding 1 Phase A and monitor the per-unit Phase A differential current until it exceeds the minimum
pickup setting. The theoretical injected current for minimum pickup verification can be computed as follows:
CT
I x = minimum pickup ----------- (EQ 9.1)
M[1]
where CT is the 1 A or 5 A tap, and M[1] is the calculated magnitude compensation factor (see the Transformer section in
Chapter 5 for details on calculating the M[1] and M[2] factors).
c) SLOPE 1 / BREAKPOINT 1
The point of Slope 1 and Breakpoint 1 is tested as follows. Refer to the Differential Restraint Characteristic diagram below
for details.
1. Inject current (Iy) into Winding 2 Phase A as follows:
CT
I YB1 = Breakpoint 1 ----------- (EQ 9.2)
M[2]
2. At Breakpoint 1, the injected current IXOP1 is determined by:
CT
I XOP1 = Breakpoint 1 1 – Slope 1 ----------- (EQ 9.3)
M[1]
and the differential current should be equal to:
I d = Slope 1 (in %) Breakpoint 1 (in pu) (EQ 9.4)
3. Preset the Ix current to 1.05 I XOP1 . Switch on the test set. The relay should restraint, as the differential to restraint
ratio will become less than the Slope 1 setting. Switch off the current.
4. Preset the Ix current to 0.95 I XOP1 . Switch on the test set. The relay should operate. Switch off the current.
To test any other point from the Slope 1 section of the curve, inject a per-unit restraint current smaller than the Breakpoint 1
current and repeat the steps above by substituting the Breakpoint 1 value with the new per-unit restraint current value into
the equations above.
d) SLOPE 2 / BREAKPOINT 2
The point of Slope 2 and Breakpoint 2 is tested as follows. Refer to the diagram below for details.
1. Preset the Iy current to a magnitude that results in the restraint current being equal to Breakpoint 2. Use the following
calculation to define the magnitude of the injected current:
CT
I YB2 = Breakpoint 2 ----------- (EQ 9.5)
M[2]
2. At the above current (restraint), the IXOP2 current required to operate the element is calculated as:
CT
I XOP2 = Breakpoint 2 1 – Slope 2 ----------- (EQ 9.6)
M[1]
3. Preset the Ix current to 1.05 I XOP1 and switch on the test set. The relay should restrain, as the differential to restraint
ratio will become less than the Slope 2 setting. Switch off the current.
4. Preset the Ix current to 0.95 I XOP1 . Switch on the test set and verify relay operation. Switch off the current.
To test any point from the Slope 2 portion of the characteristic, inject a per-unit restraint current greater than the Breakpoint
2 current as restraint and repeat the steps above by substituting the Breakpoint 2 value in the equations above with the new
per-unit restraint current value.

The T60 commissioning tests are based on secondary current injections, where two or three individually adjustable cur-
rents are required. The differential protection compares the magnitudes of the varying HV and LV currents in real time.
Therefore, the test set currents and their angles must be an exact replica of the HV and LV currents and angles shown on
the diagrams, along with the correct CT polarity and orientation.
Ensure that the thermal rating of the relay current inputs is not exceeded. Stopping the injection of the currents to the relay
by using contact outputs triggered by protection operation can prevent this from occurring.
Due to the complexity of the mathematics defining the operating characteristic of the region between Breakpoint 1 and 2,
the use of a factory-supplied Microsoft Excel simulation utility is highly recommended. This utility indicates graphically
whether the relay should operate, based on the settings and winding current injection. This allows the tester to define and
confirm various points on the operating characteristic. The spreadsheet can be found at GE Multilin website at http://

Consider the above system, which illustrates the importance of CT orientation, polarity and relay connection. These factors
will also apply when performing the tests outlined in the next examples.
The transformer high voltage (HV) and low voltage (LV) side fault currents, and angles are all related. More specifically, the
HV and LV primary fault currents are displaced by 180°. The CT polarity marks point away from the protected zone and are
connected to the ~a terminals of the relay. The displayed current is what is reported by the relay.

NOTE
a) DESCRIPTION
TRANSFORMER DATA:
• 20 MVA, 115/12.47 kV, CT (HV) = 200:1, CT (LV) = 1000:1, Y/y0° with a grounded LV neutral
TEST SET CONFIGURATION:
The fault current distribution for an external b-c fault is identical for the HV and LV transformer sides and can be simulated
easily with two current sources. Connect the first current source to the relay Phase “B” and “C” terminals, corresponding to
the HV winding CTs in series, and the second source to the Phase “b” and “c” relay terminals, corresponding to the LV CTs.
Ensure the polarity is correct and the relative phase angles are similar to the shown in the figure; that is, 180° between IB
and IC, 180° between Ib and Ic, 180° between IB and Ib, and 180° between IC and Ic. Follow the magnitudes and angles of
the injected currents from the tables below to ensure the test will be performed correctly
OPERATING CRITERIA:
The differential element operates if the differential current (Id) exceeds the characteristic defined by the relay settings for
restraint current magnitude (Ir). The differential current Id is the vector sum of the compensated currents, and Ir is the larg-
est compensated current. Compensation refers to vector and magnitude corrections applied to the currents from the HV
and LV transformer sides.
The tests verify the operation and no-operation response for points from all regions of the percentage differential character-
istic. These tests are:
• Test for zero differential current
• Minimum Pickup
• Slope 1
• The region between Slope 1 and Slope 2
• Slope 2

The relay will not operate since Id is still lower that the 0.1 pu MINIMUM PICKUP setting.
6. Increase I1 to 0.2 A. The differential current increases to I d = 0.136 pu Min PKP and I r 0.67 pu .

Inject current in such a manner that the magnitude of Ir is larger than the restraint current of 0.67 pu, corresponding to the
intersection of the minimum PKP and Slope 1 and smaller than the Breakpoint 1 setting; that is,
I r intersection of Min PKP and Slope 1 I r actual I r Break 1 (EQ 9.9)

The Percent Differential element will not operate even though Id is larger than the Minimum Pickup, because Id
is not large enough to make the I d I r ratio larger than the Slope 1 setting of 15%. The actual ratio is 11.3%.
NOTE
3. Adjust the I1 current as shown below (thereby increasing Id) and verify that the element operates.

The I d I r ratio is 36.77% and the Differential element does not operate because the actual I d = 1.287 pu is still too
low at I r = 3.5 pu .
Due to the mathematical complexity involved in shaping the curve between Breakpoint 1 and Breakpoint 2, an
Excel-based simulation tool is available from the GE Multilin website at http://www.GEindustrial.com/multilin.
NOTE
With this tool, the user can see the preset I d I r curve point ratios and the actual I d I r ratio as per the entered
test currents. The tool graphically indicates differential and restraint current magnitudes and indicates whether
the relay should operate.
3. In this example, a ratio of I d I r 38% causes the element to trip. Decreasing I1 as shown in the table below increases
the differential current Id, causing the element to operate.

g) SUMMARY
The above tests describe the principles of testing the differential element for all regions from the operating characteristic.
For verification of more points, one should consider adjusting the magnitude of the restraint current Ir to the desired portion
of the characteristic and change the other current to vary Id until the relay operates. Use the Excel tool to compare the
actual and expected operating values.

Three adjustable currents are required in this case. The Phase A and C Wye-side line currents, identical in magnitude but
displaced by 180°, can be simulated with one current source passed through these relay terminals in series. The second

The Inrush Inhibit Test requires a secondary injection test capable of producing a current with an adjustable second
harmonic component. Use the appropriate commissioning tables at the end of this chapter to record values.
NOTE
This procedure is based upon the example provided in the Differential Characteristic Test Example section. The trans-
former parameters are as follows:
Transformer: Y/y0°, 230/69 kV, CT1 (300:1), CT2 (1000:1)
2nd Harmonic Setting = 20%
1. Connect the relay test set to inject current into the Winding 1 Phase A CT input.
2. Inject currents into the relay as shown in the table below until the biased differential element picks up.
3. Confirm that only the percent differential element has operated.
4. Increase the harmonic content until the element drops out. Record this value as the Inrush Inhibit Level Pickup.
5. Gradually decrease the harmonic content level until the element picks up. Record this value as the Inrush Inhibit
Level Dropout.
6. Switch off the current.
7. Repeat steps 1 through 6 for phases B and C.
8. Repeat steps 1 through 7 for Winding 2 (and Windings 3 and 4 if necessary).
The second harmonic inhibit feature can be verified by setting the INRUSH INHIBIT MODE setting as follows:
For INRUSH INHIBIT MODE set to "2-out-of-3":
1. Set the INRUSH INHIBIT FUNCTION to "Trad. 2nd" and the INRUSH INHIBIT LEVEL to "20%".
2. Inject currents into one CT bank (one winding only) until the biased differential operates for all three phases.
3. Apply a second harmonic to Phase A higher than the set threshold and monitor operation of Phases A, B, and C. The
9 4.
element should stay operated on all three phases.
Apply a second harmonic to Phase B with a level less than the set threshold.
5. Increase the second harmonic level in Phase B. When it passes the set threshold, all three phases of differential pro-
tection should drop out.
For INRUSH INHIBIT MODE set to "Average":
1. Set the INRUSH INHIBIT FUNCTION to "Trad. 2nd" and the INRUSH INHIBIT LEVEL to "20%".
2. Inject currents into one CT bank (one winding only) until the biased differential operates for all three phases.
3. Apply a second harmonic to Phase A with a level greater than the set threshold and monitor the operation of the Per-
cent Differential element. The element should drop out when the injected second harmonic level becomes three times
larger than the set threshold.
The Overexcitation Inhibit Test requires a secondary injection from a source capable of producing an adjustable 5th
harmonic component. Use the appropriate commissioning tables at the end of this chapter to record values.
NOTE
This procedure is based upon the example provided in the Differential Characteristic Test Example section. The trans-
former parameters are as follows:
Transformer: Y/y0°, 230/69 kV, CT1 (300:1), CT2 (1000:1)
5th Harmonic Setting = 10%
1. Connect the relay test set to inject current into the Winding 1 Phase A CT input.
2. Inject a current into the relay until the biased Differential element operates.
3. Confirm that ONLY the differential element has operated.
4. Increase the 5th harmonic content level until the element drops out. Record this value as the Overexcitation Inhibit
Level Pickup.
5. Gradually decrease the harmonic content level until the element picks up. Record this value as the Overexcitation
Inhibit Level Dropout.
6. Switch off the current.
7. Repeat steps 1 through 6 for phases B and C.
8. Repeat steps 1 through 7 for winding 2 (and windings 3 and 4 if necessary).
Underfreqency and overfrequency protection requires techniques with subtle testing implications. Whereas most protection
is designed to detect changes from normal to fault conditions that occur virtually instantaneously, power system inertia
requires frequency protection to pickup while the frequency is changing slowly. Frequency measurement is inherently sen-
sitive to noise, making high precision in combination with high speed challenging for both relays and test equipment.
Injection to a particular T60 frequency element must be to its configured source and to the channels the source uses for fre-
quency measurement. For frequency measurement, a source will use the first quantity configured in the following order:
1. Phase voltages.
2. Auxiliary voltage.
3. Phase currents.
4. Ground current.
For example, if only auxiliary voltage and phase currents are configured, the source will use the auxiliary voltage, not the
phase voltages or any of the currents.
When phase voltages or phase currents are used, the source applies a filter that rejects the zero-sequence component. As
such, the same signal must not be injected to all three phases, or the injected signal will be completely filtered out. For an
underfrequency element using phase quantities, the phase A signal must be above the MIN VOLT/AMP setting value. There-
fore, either inject into phase A only, or inject a balanced three-phase signal.

Time
Underfrequency element detection time
The desired delay time is the interval from the point the frequency crosses the set threshold to the point the element oper-
ates. Some test sets can measure only the time from the ramp start to element operation, necessitating the subtraction of
the pre-threshold ramp time from the reading. For example, with a ramp rate of 0.20 Hz/s, start the ramp 0.20 Hz before the
threshold and subtract 1 second from test set time reading of ramp start to relay operation.
Note that the T60 event records only show the “pickup delay” component, a definite time timer. This is exclusive of the time
taken by the frequency responding component to pickup.
The T60 oscillography can be used to measure the time between the calculated source frequency crossing the threshold
and element operation; however, this method omits the delay in the calculated source frequency. The security features of
the source frequency measurement algorithm result in the calculated frequency being delayed by 2 to 4 cycles (or longer
with noise on the input). In addition, oscillography resolution is 0.004 Hz, which at 0.20 Hz/s corresponds to a delay of
20 ms. The tracking frequency should not be used in timing measurements, as its algorithm involves phase locking, which
purposely sets its frequency high or low to allow the T60 sample clock to catch-up or wait as necessary to reach synchro-
nism with the power system.

The UR-series relays support a number of communications protocols to allow connection to equipment such as personal
computers, RTUs, SCADA masters, and programmable logic controllers. The Modicon Modbus RTU protocol is the most
basic protocol supported by the UR. Modbus is available via RS232 or RS485 serial links or via ethernet (using the Mod-
bus/TCP specification). The following description is intended primarily for users who wish to develop their own master com-
munication drivers and applies to the serial Modbus RTU protocol. Note that:
• The UR always acts as a slave device, meaning that it never initiates communications; it only listens and responds to B
requests issued by a master computer.
• For Modbus®, a subset of the Remote Terminal Unit (RTU) protocol format is supported that allows extensive monitor-
ing, programming, and control functions using read and write register commands.
The Modbus® RTU protocol is hardware-independent so that the physical layer can be any of a variety of standard hard-
ware configurations including RS232 and RS485. The relay includes a faceplate (front panel) RS232 port and two rear ter-
minal communications ports that may be configured as RS485, fiber optic, 10Base-T, or 10Base-F. Data flow is half-duplex
in all configurations. See chapter 3 for details on communications wiring.
Each data byte is transmitted in an asynchronous format consisting of 1 start bit, 8 data bits, 1 stop bit, and possibly 1 parity
bit. This produces a 10 or 11 bit data frame. This can be important for transmission through modems at high bit rates (11 bit
data frames are not supported by many modems at baud rates greater than 300).
The baud rate and parity are independently programmable for each communications port. Baud rates of 300, 1200, 2400,
4800, 9600, 14400, 19200, 28800, 33600, 38400, 57600, or 115200 bps are available. Even, odd, and no parity are avail-
able. Refer to the Communications section of chapter 5 for further details.
The master device in any system must know the address of the slave device with which it is to communicate. The relay will
not act on a request from a master if the address in the request does not match the relay’s slave address (unless the
address is the broadcast address – see below).
A single setting selects the slave address used for all ports, with the exception that for the faceplate port, the relay will
accept any address when the Modbus® RTU protocol is used.
Communications takes place in packets which are groups of asynchronously framed byte data. The master transmits a
packet to the slave and the slave responds with a packet. The end of a packet is marked by dead-time on the communica-
tions line. The following describes general format for both transmit and receive packets. For exact details on packet format-
ting, refer to subsequent sections describing each function code.
• SLAVE ADDRESS: This is the address of the slave device that is intended to receive the packet sent by the master
and to perform the desired action. Each slave device on a communications bus must have a unique address to prevent
bus contention. All of the relay’s ports have the same address which is programmable from 1 to 254; see chapter 5 for
details. Only the addressed slave will respond to a packet that starts with its address. Note that the faceplate port is an
exception to this rule; it will act on a message containing any slave address.
A master transmit packet with slave address 0 indicates a broadcast command. All slaves on the communication link
take action based on the packet, but none respond to the master. Broadcast mode is only recognized when associated
with function code 05h. For any other function code, a packet with broadcast mode slave address 0 will be ignored.
• FUNCTION CODE: This is one of the supported functions codes of the unit which tells the slave what action to per-
form. See the Supported Function Codes section for complete details. An exception response from the slave is indi-
cated by setting the high order bit of the function code in the response packet. See the Exception Responses section
for further details.
• DATA: This will be a variable number of bytes depending on the function code. This may include actual values, set-
tings, or addresses sent by the master to the slave or by the slave to the master.
• CRC: This is a two byte error checking code. The RTU version of Modbus® includes a 16-bit cyclic redundancy check
B (CRC-16) with every packet which is an industry standard method used for error detection. If a Modbus slave device
receives a packet in which an error is indicated by the CRC, the slave device will not act upon or respond to the packet
thus preventing any erroneous operations. See the CRC-16 Algorithm section for details on calculating the CRC.
• DEAD TIME: A packet is terminated when no data is received for a period of 3.5 byte transmission times (about 15 ms
at 2400 bps, 2 ms at 19200 bps, and 300 µs at 115200 bps). Consequently, the transmitting device must not allow gaps
between bytes longer than this interval. Once the dead time has expired without a new byte transmission, all slaves
start listening for a new packet from the master except for the addressed slave.
The CRC-16 algorithm essentially treats the entire data stream (data bits only; start, stop and parity ignored) as one contin-
uous binary number. This number is first shifted left 16 bits and then divided by a characteristic polynomial
(11000000000000101B). The 16-bit remainder of the division is appended to the end of the packet, MSByte first. The
resulting packet including CRC, when divided by the same polynomial at the receiver will give a zero remainder if no trans-
mission errors have occurred. This algorithm requires the characteristic polynomial to be reverse bit ordered. The most sig-
nificant bit of the characteristic polynomial is dropped, since it does not affect the value of the remainder.
A C programming language implementation of the CRC algorithm will be provided upon request.
Modbus® officially defines function codes from 1 to 127 though only a small subset is generally needed. The relay supports
some of these functions, as summarized in the following table. Subsequent sections describe each function code in detail.
This function code allows the master to read one or more consecutive data registers (actual values or settings) from a relay.
Data registers are always 16-bit (two-byte) values transmitted with high order byte first. The maximum number of registers
that can be read in a single packet is 125. See the Modbus memory map table for exact details on the data registers.
Since some PLC implementations of Modbus only support one of function codes 03h and 04h. The T60 interpretation
allows either function code to be used for reading one or more consecutive data registers. The data starting address will
determine the type of data being read. Function codes 03h and 04h are therefore identical.
The following table shows the format of the master and slave packets. The example shows a master device requesting
three register values starting at address 4050h from slave device 11h (17 decimal); the slave device responds with the val-
ues 40, 300, and 0 from registers 4050h, 4051h, and 4052h, respectively.
This function code allows the master to perform various operations in the relay. Available operations are shown in the Sum-
mary of operation codes table below.
The following table shows the format of the master and slave packets. The example shows a master device requesting the
slave device 11h (17 decimal) to perform a reset. The high and low code value bytes always have the values “FF” and “00”
respectively and are a remnant of the original Modbus definition of this function code.

This function code allows the master to modify the contents of a single setting register in an relay. Setting registers are
always 16 bit (two byte) values transmitted high order byte first. The following table shows the format of the master and
slave packets. The example shows a master device storing the value 200 at memory map address 4051h to slave device
11h (17 dec).
This function code allows the master to modify the contents of a one or more consecutive setting registers in a relay. Setting
registers are 16-bit (two byte) values transmitted high order byte first. The maximum number of setting registers that can be
stored in a single packet is 60. The following table shows the format of the master and slave packets. The example shows
a master device storing the value 200 at memory map address 4051h, and the value 1 at memory map address 4052h to
slave device 11h (17 decimal).

Programming or operation errors usually happen because of illegal data in a packet. These errors result in an exception
response from the slave. The slave detecting one of these errors sends a response packet to the master with the high order
bit of the function code set to 1.
The following table shows the format of the master and slave packets. The example shows a master device sending the
unsupported function code 39h to slave device 11.
a) DESCRIPTION
The UR relay has a generic file transfer facility, meaning that you use the same method to obtain all of the different types of
files from the unit. The Modbus registers that implement file transfer are found in the "Modbus File Transfer (Read/Write)"
and "Modbus File Transfer (Read Only)" modules, starting at address 3100 in the Modbus Memory Map. To read a file from
the UR relay, use the following steps:
B 1. Write the filename to the "Name of file to read" register using a write multiple registers command. If the name is shorter
than 80 characters, you may write only enough registers to include all the text of the filename. Filenames are not case
sensitive.
2. Repeatedly read all the registers in "Modbus File Transfer (Read Only)" using a read multiple registers command. It is
not necessary to read the entire data block, since the UR relay will remember which was the last register you read. The
"position" register is initially zero and thereafter indicates how many bytes (2 times the number of registers) you have
read so far. The "size of..." register indicates the number of bytes of data remaining to read, to a maximum of 244.
3. Keep reading until the "size of..." register is smaller than the number of bytes you are transferring. This condition indi-
cates end of file. Discard any bytes you have read beyond the indicated block size.
4. If you need to re-try a block, read only the "size of.." and "block of data", without reading the position. The file pointer is
only incremented when you read the position register, so the same data block will be returned as was read in the pre-
vious operation. On the next read, check to see if the position is where you expect it to be, and discard the previous
block if it is not (this condition would indicate that the UR relay did not process your original read request).
The UR relay retains connection-specific file transfer information, so files may be read simultaneously on multiple Modbus
connections.
b) OTHER PROTOCOLS
All the files available via Modbus may also be retrieved using the standard file transfer mechanisms in other protocols (for
example, TFTP or MMS).

These documents can be obtained from the IEC (http://www.iec.ch). It is strongly recommended that all those involved with
any IEC 61850 implementation obtain this document set.
IEC 61850 specifies the use of the Manufacturing Message Specification (MMS) at the upper (application) layer for transfer
of real-time data. This protocol has been in existence for several of years and provides a set of services suitable for the
transfer of data within a substation LAN environment. Actual MMS protocol services are mapped to IEC 61850 abstract ser-
vices in IEC 61850-8-1.
The T60 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks.
The TP4/CLNP profile requires the T60 to have a network address or Network Service Access Point (NSAP) to establish a
communication link. The TCP/IP profile requires the T60 to have an IP address to establish communications. These
addresses are located in the SETTINGS PRODUCT SETUP COMMUNICATIONS NETWORK menu. Note that the T60
supports IEC 61850 over the TP4/CLNP or TCP/IP stacks, and also operation over both stacks simultaneously. It is possi-
ble to have up to five simultaneous connections (in addition to DNP and Modbus/TCP (non-IEC 61850) connections).
• Client/server: This is a connection-oriented type of communication. The connection is initiated by the client, and com-
munication activity is controlled by the client. IEC 61850 clients are often substation computers running HMI programs
or SOE logging software. Servers are usually substation equipment such as protection relays, meters, RTUs, trans-
former tap changers, or bay controllers.
• Peer-to-peer: This is a non-connection-oriented, high speed type of communication usually between substation equip-
ment such as protection relays. GSSE and GOOSE are methods of peer-to-peer communication.
• Substation configuration language (SCL): A substation configuration language is a number of files used to describe
the configuration of substation equipment. Each configured device has an IEC Capability Description (ICD) file. The
substation single line information is stored in a System Specification Description (SSD) file. The entire substation con-
figuration is stored in a Substation Configuration Description (SCD) file. The SCD file is the combination of the individ-
ual ICD files and the SSD file.
IEC 61850 defines an object-oriented approach to data and services. An IEC 61850 physical device can contain one or
more logical device(s). Each logical device can contain many logical nodes. Each logical node can contain many data
objects. Each data object is composed of data attributes and data attribute components. Services are available at each
level for performing various functions, such as reading, writing, control commands, and reporting.
Each T60 IED represents one IEC 61850 physical device. The physical device contains one logical device, and the logical
device contains many logical nodes. The logical node LPHD1 contains information about the T60 IED physical device. The
logical node LLN0 contains information about the T60 IED logical device.
C The GGIO1 logical node is available in the T60 to provide access to as many 128 digital status points and associated time-
stamps and quality flags. The data content must be configured before the data can be used. GGIO1 provides digital status
points for access by clients.
It is intended that clients use GGIO1 in order to access digital status values from the T60. Configuration settings are pro-
vided to allow the selection of the number of digital status indications available in GGIO1 (8 to 128), and to allow the choice
of the T60 FlexLogic™ operands that drive the status of the GGIO1 status indications. Clients can utilize the IEC 61850
buffered and unbuffered reporting features available from GGIO1 in order to build sequence of events (SOE) logs and HMI
display screens. Buffered reporting should generally be used for SOE logs since the buffering capability reduces the
chances of missing data state changes. Unbuffered reporting should generally be used for local status display.
The GGIO2 logical node is available to provide access to the T60 virtual inputs. Virtual inputs are single-point control
(binary) values that can be written by clients. They are generally used as control inputs. GGIO2 provides access to the vir-
tual inputs through the IEC 61850 standard control model (ctlModel) services:
• Status only.
• Direct control with normal security.
• SBO control with normal security.
Configuration settings are available to select the control model for each point. Each virtual input used through GGIO2
should have its VIRTUAL INPUT 1(64) FUNCTION setting programmed as “Enabled” and its corresponding GGIO2 CF SPSCO1(64)
CTLMODEL setting programmed to the appropriate control configuration.
C.2.4 GGIO3: DIGITAL STATUS AND ANALOG VALUES FROM RECEIVED GOOSE DATA
The GGIO3 logical node is available to provide access for clients to values received via configurable GOOSE messages.
The values of the digital status indications and analog values in GGIO3 originate in GOOSE messages sent from other
devices.
The GGIO4 logical node provides access to as many as 32 analog value points, as well as associated timestamps and
quality flags. The data content must be configured before the data can be used. GGIO4 provides analog values for access
by clients.
It is intended that clients use GGIO4 to access generic analog values from the T60. Configuration settings allow the selec-
tion of the number of analog values available in GGIO4 (4 to 32) and the choice of the FlexAnalog™ values that determine
the value of the GGIO4 analog inputs. Clients can utilize polling or the IEC 61850 unbuffered reporting feature available
from GGIO4 in order to obtain the analog values provided by GGIO4.
A limited number of measured analog values are available through the MMXU logical nodes.
Each MMXU logical node provides data from a T60 current and voltage source. There is one MMXU available for each con-
figurable source (programmed in the SETTINGS SYSTEM SETUP SIGNAL SOURCES menu). MMXU1 provides data
from T60 source 1, and MMXU2 provides data from T60 source 2.
MMXU data is provided in two forms: instantaneous and deadband. The instantaneous values are updated every time a
read operation is performed by a client. The deadband values are calculated as described in IEC 61850 parts 7-1 and 7-3.
The selection of appropriate deadband settings for the T60 is described in chapter 5 of this manual.

The following list describes the protection elements for all UR-series relays. The T60 relay will contain a subset of protec-
tion elements from this list.
• PDIF: bus differential, transformer instantaneous differential, transformer percent differential, current differential
IEC 61850 buffered and unbuffered reporting is provided in the GGIO1 logical nodes (for binary status values) and MMXU1
to MMXU6 (for analog measured values). Report settings can be configured using the EnerVista UR Setup software, sub-
station configurator software, or via an IEC 61850 client. The following items can be configured:
• TrgOps: Trigger options. The following bits are supported by the T60:
– Bit 1: data-change
– Bit 4: integrity
– Bit 5: general interrogation
• OptFlds: Option Fields. The following bits are supported by the T60:
–
–
Bit 1: sequence-number
Bit 2: report-time-stamp
C
– Bit 3: reason-for-inclusion
– Bit 4: data-set-name
– Bit 5: data-reference
– Bit 6: buffer-overflow (for buffered reports only)
– Bit 7: entryID (for buffered reports only)
– Bit 8: conf-revision
– Bit 9: segmentation
• IntgPd: Integrity period.
• BufTm: Buffer time.
MMS file services are supported to allow transfer of oscillography, event record, or other files from a T60 relay.
The timestamp values associated with all IEC 61850 data items represent the time of the last change of either the value or
quality flags of the data item. To accomplish this functionality, all IEC 61850 data items must be regularly scanned for data
changes, and the timestamp updated when a change is detected, regardless of the connection status of any IEC 61850 cli-
ents. For applications where there is no IEC 61850 client in use, the IEC 61850 SERVER SCANNING setting can be pro-
grammed as “Disabled”. If a client is in use, this setting should be programmed as “Enabled” to ensure the proper
generation of IEC 61850 timestamps.
The logical device name is used to identify the IEC 61850 logical device that exists within the T60. This name is composed
of two parts: the IED name setting and the logical device instance. The complete logical device name is the combination of
the two character strings programmed in the IEDNAME and LD INST settings. The default values for these strings are “IED-
Name” and “LDInst”. These values should be changed to reflect a logical naming convention for all IEC 61850 logical
devices in the system.
C.3.5 LOCATION
The LPHD1 logical node contains a data attribute called location (LPHD1.DC.PhyNam.location). This is a character string
meant to describe the physical location of the T60. This attribute is programmed through the LOCATION setting and its
default value is “Location”. This value should be changed to describe the actual physical location of the T60.
IEC 61850 specifies that each logical node can have a name with a total length of 11 characters. The name is composed of:
• A five or six-character name prefix.
• A four-character standard name (for example, MMXU, GGIO, PIOC, etc.).
• A one or two-character instantiation index.
Complete names are of the form xxxxxxPIOC1, where the xxxxxx character string is configurable. Details regarding the
logical node naming rules are given in IEC 61850 parts 6 and 7-2. It is recommended that a consistent naming convention
be used for an entire substation project.
C A built-in TCP/IP connection timeout of two minutes is employed by the T60 to detect ‘dead’ connections. If there is no data
traffic on a TCP connection for greater than two minutes, the connection will be aborted by the T60. This frees up the con-
nection to be used by other clients. Therefore, when using IEC 61850 reporting, clients should configure report control
block items such that an integrity report will be issued at least every 2 minutes (120000 ms). This ensures that the T60 will
not abort the connection. If other MMS data is being polled on the same connection at least once every 2 minutes, this tim-
eout will not apply.
The T60 relay makes available a number of non-IEC 61850 data items. These data items can be accessed through the
“UR” MMS domain. IEC 61850 data can be accessed through the standard IEC 61850 logical device. To access the non-
IEC data items, the INCLUDE NON-IEC DATA setting must be “Enabled”.
The exact structure and values of the supported IEC 61850 logical nodes can be seen by connecting to a T60 relay with an
MMS browser, such as the “MMS Object Explorer and AXS4-MMS” DDE/OPC server from Sisco Inc.
IEC 61850 specifies two types of peer-to-peer data transfer services: Generic Substation State Events (GSSE) and Generic
Object Oriented Substation Events (GOOSE). GSSE services are compatible with UCA 2.0 GOOSE. IEC 61850 GOOSE
services provide virtual LAN (VLAN) support, Ethernet priority tagging, and Ethertype Application ID configuration. The sup-
port for VLANs and priority tagging allows for the optimization of Ethernet network traffic. GOOSE messages can be given
a higher priority than standard Ethernet traffic, and they can be separated onto specific VLANs. Because of the additional
features of GOOSE services versus GSSE services, it is recommended that GOOSE be used wherever backwards com-
patibility with GSSE (or UCA 2.0 GOOSE) is not required.
Devices that transmit GSSE and/or GOOSE messages also function as servers. Each GSSE publisher contains a “GSSE
control block” to configure and control the transmission. Each GOOSE publisher contains a “GOOSE control block” to con-
figure and control the transmission. The transmission is also controlled via device settings. These settings can be seen in
the ICD and/or SCD files, or in the device configuration software or files.
IEC 61850 recommends a default priority value of 4 for GOOSE. Ethernet traffic that does not contain a priority tag has a
C
default priority of 1. More details are specified in IEC 61850 part 8-1.
IEC 61850 recommends that the Ethertype Application ID number be configured according to the GOOSE source. In the
T60, the transmitted GOOSE Application ID number must match the configured receive Application ID number in the
receiver. A common number may be used for all GOOSE transmitters in a system. More details are specified in IEC 61850
part 8-1.
IEC 61850 Generic Substation Status Event (GSSE) communication is compatible with UCA GOOSE communication.
GSSE messages contain a number of double point status data items. These items are transmitted in two pre-defined data
structures named DNA and UserSt. Each DNA and UserSt item is referred to as a ‘bit pair’. GSSE messages are transmit-
ted in response to state changes in any of the data points contained in the message. GSSE messages always contain the
same number of DNA and UserSt bit pairs. Depending the on the configuration, only some of these bit pairs may have val-
ues that are of interest to receiving devices.
The GSSE FUNCTION, GSSE ID, and GSSE DESTINATION MAC ADDRESS settings are used to configure GSSE transmission.
GSSE FUNCTION is set to “Enabled” to enable the transmission. If a valid multicast Ethernet MAC address is entered for the
GSSE DESTINATION MAC ADDRESS setting, this address will be used as the destination MAC address for GSSE messages. If
a valid multicast Ethernet MAC address is not entered (for example, 00 00 00 00 00 00), the T60 will use the source Ether-
net MAC address as the destination, with the multicast bit set.
The T60 supports two types of IEC 61850 Generic Object Oriented Substation Event (GOOSE) communication: fixed
GOOSE and configurable GOOSE. All GOOSE messages contain IEC 61850 data collected into a dataset. It is this dataset
that is transferred using GOOSE message services. The dataset transferred using the T60 fixed GOOSE is the same data
that is transferred using the GSSE feature; that is, the DNA and UserSt bit pairs. The FlexLogic™ operands that determine
the state of the DNA and UserSt bit pairs are configurable via settings, but the fixed GOOSE dataset always contains the
same DNA/UserSt data structure. Upgrading from GSSE to GOOSE services is simply a matter of enabling fixed GOOSE
and disabling GSSE. The remote inputs and outputs are configured in the same manner for both GSSE and fixed GOOSE.
It is recommended that the fixed GOOSE be used for implementations that require GOOSE data transfer between UR-
series IEDs. Configurable GOOSE may be used for implementations that require GOOSE data transfer between UR-series
IEDs and devices from other manufacturers.
The configurable GOOSE feature allows for the configuration of the datasets to be transmitted or received from the T60.
The T60 supports the configuration of eight (8) transmission and reception datasets, allowing for the optimization of data
transfer between devices.
Items programmed for dataset 1 and 2 will have changes in their status transmitted as soon as the change is detected.
Dataset 1 should be used for high-speed transmission of data that is required for applications such as transfer tripping,
blocking, and breaker fail initiate. At least one digital status value needs to be configured in dataset 1 to enable transmis-
sion of all data configured for dataset 1. Configuring analog data only to dataset 1 will not activate transmission.
Items programmed for datasets 3 through 8 will have changes in their status transmitted at a maximum rate of every
100 ms. Datasets 3 through 8 will regularly analyze each data item configured within them every 100 ms to identify if any
changes have been made. If any changes in the data items are detected, these changes will be transmitted through a
GOOSE message. If there are no changes detected during this 100 ms period, no GOOSE message will be sent.
For all datasets 1 through 8, the integrity GOOSE message will still continue to be sent at the pre-configured rate even if no
changes in the data items are detected.
The GOOSE functionality was enhanced to prevent the relay from flooding a communications network with GOOSE mes-
sages due to an oscillation being created that is triggering a message.
C The T60 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be
caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station
components. If erroneously oscillation is detected, the T60 will stop sending GOOSE messages from the dataset for a min-
imum period of one second. Should the oscillation persist after the one second time-out period, the T60 will continue to
block transmission of the dataset. The T60 will assert the MAINTENANCE ALERT: GGIO Ind XXX oscill self-test error mes-
sage on the front panel display, where XXX denotes the data item detected as oscillating.
The configurable GOOSE feature is recommended for applications that require GOOSE data transfer between UR-series
IEDs and devices from other manufacturers. Fixed GOOSE is recommended for applications that require GOOSE data
transfer between UR-series IEDs.
IEC 61850 GOOSE messaging contains a number of configurable parameters, all of which must be correct to achieve the
successful transfer of data. It is critical that the configured datasets at the transmission and reception devices are an exact
match in terms of data structure, and that the GOOSE addresses and name strings match exactly. Manual configuration is
possible, but third-party substation configuration software may be used to automate the process. The EnerVista UR Setup-
software can produce IEC 61850 ICD files and import IEC 61850 SCD files produced by a substation configurator (refer to
the IEC 61850 IED configuration section later in this appendix).
The following example illustrates the configuration required to transfer IEC 61850 data items between two devices. The
general steps required for transmission configuration are:
1. Configure the transmission dataset.
2. Configure the GOOSE service settings.
3. Configure the data.
The general steps required for reception configuration are:
1. Configure the reception dataset.
2. Configure the GOOSE service settings.
3. Configure the data.
This example shows how to configure the transmission and reception of three IEC 61850 data items: a single point status
value, its associated quality flags, and a floating point analog value.
The following procedure illustrates the transmission configuration.
1. Configure the transmission dataset by making the following changes in the PRODUCT SETUP COMMUNICATION
IEC 61850 PROTOCOL GSSE/GOOSE CONFIGURATION TRANSMISSION CONFIGURABLE GOOSE CONFIGURABLE
GOOSE 1 CONFIG GSE 1 DATASET ITEMS settings menu:
– Set ITEM 1 to “GGIO1.ST.Ind1.q” to indicate quality flags for GGIO1 status indication 1.
– Set ITEM 2 to “GGIO1.ST.Ind1.stVal” to indicate the status value for GGIO1 status indication 1.
The transmission dataset now contains a set of quality flags and a single point status Boolean value. The reception
dataset on the receiving device must exactly match this structure.
2. Configure the GOOSE service settings by making the following changes in the PRODUCT SETUP COMMUNICATION
IEC 61850 PROTOCOL GSSE/GOOSE CONFIGURATION TRANSMISSION CONFIGURABLE GOOSE CONFIGU-
RABLE GOOSE 1 settings menu:

settings menu:
Set GGIO1 INDICATION 1 to a FlexLogic™ operand used to provide the status of GGIO1.ST.Ind1.stVal (for example,
C
a contact input, virtual input, a protection element status, etc.).
The T60 must be rebooted (control power removed and re-applied) before these settings take effect.
The following procedure illustrates the reception configuration.
1. Configure the reception dataset by making the following changes in the PRODUCT SETUP COMMUNICATION IEC
61850 PROTOCOL GSSE/GOOSE CONFIGURATION RECEPTION CONFIGURABLE GOOSE CONFIGURABLE GOOSE
1 CONFIG GSE 1 DATASET ITEMS settings menu:
– Set ITEM 1 to “GGIO3.ST.Ind1.q” to indicate quality flags for GGIO3 status indication 1.
– Set ITEM 2 to “GGIO3.ST.Ind1.stVal” to indicate the status value for GGIO3 status indication 1.
The reception dataset now contains a set of quality flags, a single point status Boolean value, and a floating point ana-
log value. This matches the transmission dataset configuration above.
2. Configure the GOOSE service settings by making the following changes in the INPUTS/OUTPUTS REMOTE DEVICES
REMOTE DEVICE 1 settings menu:
– Set REMOTE DEVICE 1 ID to match the GOOSE ID string for the transmitting device. Enter “GOOSEOut_1”.
– Set REMOTE DEVICE 1 ETYPE APPID to match the Ethertype application ID from the transmitting device. This is “0” in
the example above.
– Set the REMOTE DEVICE 1 DATASET value. This value represents the dataset number in use. Since we are using
configurable GOOSE 1 in this example, program this value as “GOOSEIn 1”.
3. Configure the data by making the following changes in the INPUTS/OUTPUTS REMOTE INPUTS REMOTE INPUT 1
settings menu:
– Set REMOTE IN 1 DEVICE to “GOOSEOut_1”.
– Set REMOTE IN 1 ITEM to “Dataset Item 2”. This assigns the value of the GGIO3.ST.Ind1.stVal single point status
item to remote input 1.
Remote input 1 can now be used in FlexLogic™ equations or other settings. The T60 must be rebooted (control power
removed and re-applied) before these settings take effect.
The value of remote input 1 (Boolean on or off) in the receiving device will be determined by the GGIO1.ST.Ind1.stVal value
in the sending device. The above settings will be automatically populated by the EnerVista UR Setup software when a com-
plete SCD file is created by third party substation configurator software.
Ethernet capable devices each contain a unique identifying address called a Media Access Control (MAC) address. This
address cannot be changed and is unique for each Ethernet device produced worldwide. The address is six bytes in length
and is usually represented as six hexadecimal values (for example, 00 A0 F4 01 02 03). It is used in all Ethernet frames as
the ‘source’ address of the frame. Each Ethernet frame also contains a destination address. The destination address can
be different for each Ethernet frame depending on the intended destination of the frame.
A special type of destination address called a multicast address is used when the Ethernet frame can be received by more
than one device. An Ethernet MAC address is multicast when the least significant bit of the first byte is set (for example, 01
00 00 00 00 00 is a multicast address).
GSSE and GOOSE messages must have multicast destination MAC addresses.
By default, the T60 is configured to use an automated multicast MAC scheme. If the T60 destination MAC address setting
is not a valid multicast address (that is, the least significant bit of the first byte is not set), the address used as the destina-
tion MAC will be the same as the local MAC address, but with the multicast bit set. Thus, if the local MAC address is 00 A0
F4 01 02 03, then the destination MAC address will be 01 A0 F4 01 02 03.
GSSE messages contain an identifier string used by receiving devices to identify the sender of the message, defined in IEC
C 61850 part 8-1 as GsID. This is a programmable 65-character string. This string should be chosen to provide a descriptive
name of the originator of the GSSE message.
GOOSE messages contain an identifier string used by receiving devices to identify the sender of the message, defined in
IEC 61850 part 8-1 as GoID. This programmable 65-character string should be a descriptive name of the originator of the
GOOSE message. GOOSE messages also contain two additional character strings used for identification of the message:
DatSet - the name of the associated dataset, and GoCBRef - the reference (name) of the associated GOOSE control block.
These strings are automatically populated and interpreted by the T60; no settings are required.
The T60 can be configured for IEC 61850 via the EnerVista UR Setup software as follows.
1. An ICD file is generated for the T60 by the EnerVista UR Setup software that describe the capabilities of the IED.
2. The ICD file is then imported into a system configurator along with other ICD files for other IEDs (from GE or other ven-
dors) for system configuration.
3. The result is saved to a SCD file, which is then imported back to EnerVista UR Setup to create one or more settings
file(s). The settings file(s) can then be used to update the relay(s) with the new configuration information.
The configuration process is illustrated below.

Before creating an ICD file, the user can customize the IEC 61850 related settings for the IED. For example, the IED name
and logical device instance can be specified to uniquely identify the IED within the substation, or transmission GOOSE
datasets created so that the system configurator can configure the cross-communication links to send GOOSE messages
from the IED. Once the IEC 61850 settings are configured, the ICD creation process will recognize the changes and gener-
ate an ICD file that contains the updated settings.
Some of the IED settings will be modified during they system configuration process. For example, a new IP address may be
assigned, line items in a Transmission GOOSE dataset may be added or deleted, or prefixes of some logical nodes may be
changed. While all new configurations will be mapped to the T60 settings file when importing an SCD file, all unchanged
settings will preserve the same values in the new settings file.
These settings can be configured either directly through the relay panel or through the EnerVista UR Setup software (pre-
ferred method). The full list of IEC 61850 related settings for are as follows:
• Network configuration: IP address, IP subnet mask, and default gateway IP address (access through the Settings >
Product Setup > Communications > Network menu tree in EnerVista UR Setup).
• Server configuration: IED name and logical device instance (access through the Settings > Product Setup > Com-
munications > IEC 61850 > Server Configuration menu tree in EnerVista UR Setup).
• Logical node prefixes, which includes prefixes for all logical nodes except LLN0 (access through the Settings > Prod-
uct Setup > Communications > IEC 61850 > Logical Node Prefixes menu tree in EnerVista UR Setup).
• MMXU deadbands, which includes deadbands for all available MMXUs. The number of MMXUs is related to the num-
ber of CT/VT modules in the relay. There are two MMXUs for each CT/VT module. For example, if a relay contains two
CT/VT modules, there will be four MMXUs available (access through the Settings > Product Setup > Communica-
tions > IEC 61850 > MMXU Deadbands menu tree in EnerVista UR Setup).
• GGIO1 status configuration, which includes the number of status points in GGIO1 as well as the potential internal map-
pings for each GGIO1 indication. However only the number of status points will be used in the ICD creation process
(access through the Settings > Product Setup > Communications > IEC 61850 > GGIO1 Status Configuration
menu tree in EnerVista UR Setup).
• GGIO2 control configuration, which includes ctlModels for all SPCSOs within GGIO2 (access through the Settings >
Product Setup > Communications > IEC 61850 > GGIO2 Control Configuration menu tree in EnerVista UR
Setup).
• Configurable transmission GOOSE, which includes eight configurable datasets that can be used for GOOSE transmis-
sion. The GOOSE ID can be specified for each dataset (it must be unique within the IED as well as across the whole
substation), as well as the destination MAC address, VLAN priority, VLAN ID, ETYPE APPID, and the dataset items.
C
The selection of the dataset item is restricted by firmware version; for version 5.9x, only GGIO1.ST.Indx.stVal and
GGIO1.ST.Indx.q are valid selection (where x is between 1 to N, and N is determined by number of GGIO1 status
points). Although configurable transmission GOOSE can also be created and altered by some third-party system con-
figurators, we recommend configuring transmission GOOSE for GE Multilin IEDs before creating the ICD, and strictly
within EnerVista UR Setup software or the front panel display (access through the Settings > Product Setup > Com-
munications > IEC 61850 > GSSE/GOOSE Configuration > Transmission > Tx Configurable GOOSE menu tree
in EnerVista UR Setup).
• Configurable reception GOOSE, which includes eight configurable datasets that can be used for GOOSE reception.
However, unlike datasets for transmission, datasets for reception only contains dataset items, and they are usually cre-
ated automatically by process of importing the SCD file (access through the Settings > Product Setup > Communi-
cations > IEC 61850 > GSSE/GOOSE Configuration > Reception > Rx Configurable GOOSE menu tree in
EnerVista UR Setup).
• Remote devices configuration, which includes remote device ID (GOOSE ID or GoID of the incoming transmission
GOOSE dataset), ETYPE APPID (of the GSE communication block for the incoming transmission GOOSE), and
DATASET (which is the name of the associated reception GOOSE dataset). These settings are usually done automat-
ically by process of importing SCD file (access through the Settings > Inputs/Outputs > Remote Devices menu tree
in EnerVista UR Setup).
• Remote inputs configuration, which includes device (remote device ID) and item (which dataset item in the associated
reception GOOSE dataset to map) values. Only the items with cross-communication link created in SCD file should be
mapped. These configurations are usually done automatically by process of importing SCD file (access through the
Settings > Inputs/Outputs > Remote Inputs menu tree in EnerVista UR Setup).
The SCL language is based on XML, and its syntax definition is described as a W3C XML Schema. ICD is one type of SCL
file (which also includes SSD, CID and SCD files). The ICD file describes the capabilities of an IED and consists of four
major sections:
• Header
• Communication
• IEDs
• DataTypeTemplates

The DataTypeTemplates node defines instantiable logical node types. A logical node type is an instantiable template of the
data of a logical node. A LnodeType is referenced each time that this instantiable type is needed with an IED. A logical
node type template is built from DATA (DO) elements, which again have a DO type, which is derived from the DATA classes
(CDC). DOs consist of attributes (DA) or of elements of already defined DO types (SDO). The attribute (DA) has a func-
tional constraint, and can either have a basic type, be an enumeration, or a structure of a DAType. The DAType is built from
BDA elements, defining the structure elements, which again can be BDA elements of have a base type such as DA.

An ICD file can be created directly from a connected T60 IED or from an offline T60 settings file with the EnerVista UR
Setup software using the following procedure:
1. Right-click the connected UR-series relay or settings file and select Create ICD File.
2. The EnerVista UR Setup will prompt to save the file. Select the file path and enter the name for the ICD file, then click
OK to generate the file.
The time to create an ICD file from the offline T60 settings file is typically much quicker than create an ICD file directly from
the relay.
System configuration is performed in the system configurator. While many vendors (including GE Multilin) are working their
own system configuration tools, there are some system configurators available in the market (for example, Siemens DIGSI
version 4.6 or above and ASE Visual SCL Beta 0.12).
Although the configuration tools vary from one vendor to another, the procedure is pretty much the same. First, a substation
project must be created, either as an empty template or with some system information by importing a system specification
file (SSD). Then, IEDs are added to the substation. Since each IED is represented by its associated ICD, the ICD files are
imported into the substation project, and the system configurator validates the ICD files during the importing process. If the
ICD files are successfully imported into the substation project, it may be necessary to perform some additional minor steps
to attach the IEDs to the substation (see the system configurator manual for details).
Once all IEDs are inserted into the substation, further configuration is possible, such as:
• Assigning network addresses to individual IEDs.
• Customizing the prefixes of logical nodes.
• Creating cross-communication links (configuring GOOSE messages to send from one IED to others).
When system configurations are complete, the results are saved to an SCD file, which contains not only the configuration
for each IED in the substation, but also the system configuration for the entire substation. Finally, the SCD file is passed
back to the IED configurator (vendor specific tool) to update the new configuration into the IED.
The SCD file consists of at least five major sections:
• Header.
• Substation.
• Communication.
• IED section (one or more).
• DataTypeTemplates.
The root file structure of an SCD file is illustrated below.

The following procedure describes how to update the T60 with the new configuration from an SCD file with the EnerVista
UR Setup software.
1. Right-click anywhere in the files panel and select the Import Contents From SCD File item.
3. The software will open the SCD file and then prompt the user to save a UR-series settings file. Select a location and
name for the URS (UR-series relay settings) file.
If there is more than one GE Multilin IED defined in the SCD file, the software prompt the user to save a UR-series set-
tings file for each IED.
4. After the URS file is created, modify any settings (if required).
5. To update the relay with the new settings, right-click on the settings file in the settings tree and select the Write Set-
tings File to Device item.
6. The software will prompt for the target device. Select the target device from the list provided and click Send. The new
settings will be updated to the selected device.

The UR-series of relays supports IEC 61850 logical nodes as indicated in the following table. Note that the actual instantia-
tion of each logical node is determined by the product order code. For example. the logical node “PDIS” (distance protec-
tion) is available only in the D60 Line Distance Relay.
This document is adapted from the IEC 60870-5-104 standard. For ths section the boxes indicate the following: – used in

Explanation of ‘Sometimes’: Object 12 points are mapped to UR Virtual Inputs. The persistence of Virtual Inputs is
determined by the VIRTUAL INPUT X TYPE settings. Both “Pulse On” and “Latch On” operations perform the same func-
tion in the UR; that is, the appropriate Virtual Input is put into the “On” state. If the Virtual Input is set to “Self-Reset”,
it will reset after one pass of FlexLogic™. The On/Off times and Count value are ignored. “Pulse Off” and “Latch Off”
operations put the appropriate Virtual Input into the “Off” state. “Trip” and “Close” operations both put the appropriate
Virtual Input into the “On” state.

The following table identifies the variations, function codes, and qualifiers supported by the T60 in both request messages
and in response messages. For static (non-change-event) objects, requests sent with qualifiers 00, 01, 06, 07, or 08, will be
responded with qualifiers 00 or 01. Static object requests sent with qualifiers 17 or 28 will be responded with qualifiers 17 or
28. For change-event objects, qualifiers 17 or 28 are always responded.

Note 1: A default variation refers to the variation responded when variation 0 is requested and/or in class 0, 1, 2, or 3 scans. The default varia-
tions for object types 1, 2, 20, 21, 22, 23, 30, and 32 are selected via relay settings. Refer to the Communications section in Chapter 5
for details. This optimizes the class 0 poll data size.
Note 2: For static (non-change-event) objects, qualifiers 17 or 28 are only responded when a request is sent with qualifiers 17 or 28, respec-
tively. Otherwise, static object requests sent with qualifiers 00, 01, 06, 07, or 08, will be responded with qualifiers 00 or 01 (for change-
event objects, qualifiers 17 or 28 are always responded.)
Note 3: Cold restarts are implemented the same as warm restarts – the T60 is not restarted, but the DNP process is restarted.
The DNP binary input data points are configured through the PRODUCT SETUP COMMUNICATIONS DNP / IEC104 POINT
LISTS BINARY INPUT / MSP POINTS menu. Refer to the Communications section of Chapter 5 for additional details. When a
freeze function is performed on a binary counter point, the frozen value is available in the corresponding frozen counter
point.
Supported Control Relay Output Block fields: Pulse On, Pulse Off, Latch On, Latch Off, Paired Trip, Paired Close.
E.2.3 COUNTERS
The following table lists both Binary Counters (Object 20) and Frozen Counters (Object 21). When a freeze function is per-
formed on a Binary Counter point, the frozen value is available in the corresponding Frozen Counter point.
BINARY COUNTERS
Static (Steady-State) Object Number: 20
Change Event Object Number: 22
Request Function Codes supported: 1 (read), 7 (freeze), 8 (freeze noack), 9 (freeze and clear),
10 (freeze and clear, noack), 22 (assign class)
Static Variation reported when variation 0 requested: 1 (32-Bit Binary Counter with Flag)
Change Event Variation reported when variation 0 requested: 1 (32-Bit Counter Change Event without time)
Change Event Buffer Size: 10
Default Class for all points: 3
FROZEN COUNTERS
Static (Steady-State) Object Number: 21
Change Event Object Number: 23
Request Function Codes supported: 1 (read)
Static Variation reported when variation 0 requested: 1 (32-Bit Frozen Counter with Flag)
E Change Event Variation reported when variation 0 requested: 1 (32-Bit Frozen Counter Event without time)
Change Event Buffer Size: 10
Default Class for all points: 3
A counter freeze command has no meaning for counters 8 and 9. T60 Digital Counter values are represented as 32-bit inte-
gers. The DNP 3.0 protocol defines counters to be unsigned integers. Care should be taken when interpreting negative
counter values.
The DNP analog input data points are configured through the PRODUCT SETUP COMMUNICATIONS DNP / IEC104 POINT
LISTS ANALOG INPUT / MME POINTS menu. Refer to the Communications section of Chapter 5 for additional details.
It is important to note that 16-bit and 32-bit variations of analog inputs are transmitted through DNP as signed numbers.
Even for analog input points that are not valid as negative values, the maximum positive representation is 32767 for 16-bit
values and 2147483647 for 32-bit values. This is a DNP requirement.
The deadbands for all Analog Input points are in the same units as the Analog Input quantity. For example, an Analog Input
quantity measured in volts has a corresponding deadband in units of volts. This is in conformance with DNP Technical Bul-
letin 9809-001: Analog Input Reporting Deadband. Relay settings are available to set default deadband values according to
data type. Deadbands for individual Analog Input Points can be set using DNP Object 34.
