Medium Voltage Distribution

N-Series Three-Phase Recloser

with ADVC Controller

Make the most of your energy SM

Applications
Smart Grid Ready
With the increasing push for advanced monitoring, reduction of
outages, and the need to facilitate two-way communications
between supply and the distribution network, the N-Series
Automatic Circuit Recloser is ready to be integrated into your
smart grid solution.

Loop Automation
Restoring power to your customers in the shortest possible time is
the focus of Recloser Solutions’ Loop Automation Scheme.

The Loop Automation Scheme reconfigures protection settings,

sectionalizes faults, minimizes affected areas, and restores network
supply without the need for communications or operator
intervention, using standard recloser features.

Automatic Changeover (ACO)

The Automatic Changeover (ACO) System uses primary and
alternative supplies, master and slave reclosers, and fast
communications to ensure that supply is always available for a
critical load in the event of a power failure.

Using a number of different setups, including break-before-make and

make-before-break, allows the system to be configured to the exact
specifications required for the critical load. The system can even be
set up for one-way or two-way switching to ensure power is always
available to your critical systems.

Operation as a Sectionalizer
Reclosers and sectionalizers work together to further improve feeder
reliability. Using a separate RL-Series LBS/Sectionalizer, as part of
a feeder automation network, detects fault passage and
automatically isolates faulty sections of a network in conjunction with
upstream recloser operation. To accomplish this it senses the
three-phase current and voltage to count the number of recloser trip
operations. When the preprogrammed number of recloser
operations is reached, the controller opens the sectionalizer during
the recloser dead time to isolate the downstream fault.

General Protection Features (continued)
Inrush Restraint
Inrush restraint raises the phase and ground threshold currents for a short period of time to
allow for short duration inrush currents when closing onto a load.

period of time.

Constantrange:

> Time constant resolution: 1 min.

Multiple Protection Groups

The ADVC supports up to 10 protection groups, each of which can be configured with
completely separate protection characteristics with different inverse time curves and setting
currents. The number of protection groups available to the operator can be configured using
WSOS, thereby restricting or enabling access to protection settings as required.

Automatic Protection Group Selection

Automatic protection group selection (APGS) is used to change the protection group
depending on the direction of power flow. This allows the recloser to be correctly graded with
devices downstream regardless of the power flow direction.

Loss of Phase
WSOS offers a quick, easy way to configure the protection groups.
Loss of phase protection trips the recloser if phase-ground voltage on one or two phases falls
below a set voltage threshold for a set length of time.

> Threshold voltage range: 2 – 15 kV

> Voltage resolution: 1V
> Time range: 0.1 – 100 sec.
> Time resolution: 0.1 sec.

Live Load Blocking

Live load blocking prevents a recloser from closing if any of the load side terminals are live.

> Live load threshold voltage range: 2 – 15 kV

Dead Lockout
Dead lockout prevents a reclose unless one or more of the source side or load side terminals
are live. If all terminals are dead then the controller goes to lockout.

Advanced Protection Features
Directional Blocking
Directional blocking is a protection feature that restricts tripping on faults to a designated side
of the recloser. It prevents nuisance tripping if particular network conditions are causing “false”
ground faults. In radial systems, directional blocking prevents nuisance tripping by blocking
faults in the source direction and only responding to faults in the load direction.

feature.

Sequence Components
Negative-, positive-, and zero-phase sequence currents and voltages can be monitored
and logged.

In addition, the negative-phase sequence current protection can be used for detection of
low-level phase-to-phase faults in the presence of high-level, three-phase loads. Inverse time,
definite time, and instantaneous operation is available.

Measurement Features
RMS Voltage and Current
True root mean square (RMS) voltage is measured on all six terminals. A user-configured
threshold indicates a live terminal (accuracy ±2.5%). RMS current is measured on three
phases (reading 2 – 800 A).

Real Power (Signed or Unsigned)

Real power is determined by multiplying the line voltage and line current in real time and
averaging over 2 seconds (accuracy ±5% of reading, within limits of V and I above).

Power and Power Factor

The ADVC Controller measures kW, kVA, kVAr, and power factor on a per-phase basis. The
power factor of the line is determined from the line voltage and the line-current phase relationship
and the previously calculated real power (accuracy ±5% of reading, within limits of V and I above).

Default Historical Measurements

Power flow is integrated over 5-, 15-, 30-, or 60-minute intervals (kWh) and recorded for two
months at the default setting. This can be viewed on the operator control panel, computer, or
compatible SCADA system. Additionally, data can be uploaded into a portable computer or a
compatible SCADA system.

Configurable Historical Measurements

Average demand profiles may be configured using WSOS. Customized configuration enables
the user to specify only the parameters that are required, negating unnecessary information
capture. Parameters such as line voltages and currents, power, kWh, battery voltage, and
cubicle temperature can be recorded in intervals selectable between 1 and 1,440 min.

Event History
> Maximum number of typical events stored in the event history: 30,000 events
Gas Pressure Measurement (SF6 or Dry Air “N-green” Option)
> Gas pressure display resolution: .725 psi (5 kPa)
> Gas pressure display accuracy: ± 1.45 psi (±10 kPa)
> Gas low alarm setting: 9.427 psi gauge @ 68 °F (65 kPa gauge @ 20 °C)
> Gas low alarm/interlock accuracy: ±1.45 psi (±10 kPa)
