Power Meter Characteristics

The power meter measures currents and voltages and reports in real time rms values for all 3-phases
and neutral. In addition, the power meter calculates power factor, real power, reactive power, and more.
The following tables list the metering characteristics of the power meter. If the values are not specifically
mentioned, you can obtain the values through HMI and communication.

Minimum/Maximum Values
When any one-second real-time reading reaches its highest or lowest value, the power meter saves the
values in its nonvolatile memory. These values are called the minimum and maximum (min./max.) values.
From the power meter display, you can:
view all min./max. values since the last reset and the reset date and time.
reset min./max. values.
All running min./max. values are arithmetic minimum and maximum values. For example, the minimum
phase A-N voltage is the lowest value in the range from 0 to 1 MV that has occurred since last reset of
the min./max. values.
The power meter provides time stamping for 6 important minimum/maximum values. Refer to register
number 45130 to 45164 in the register list for details.
The following table lists the minimum and maximum values stored in the power meter:

Demand Calculation Methods

Power demand is the energy accumulated during a specified period divided by the length of the period.
Current demand is calculated using arithmetical integration of the current rms values during a period of
time, divided by the length of the period. How the power meter performs this calculation depends on the
selected method. To be compatible with electric utility billing practices, the power meter provides the
block interval power/current demand calculations. The default demand calculation is set to a fixed block
with a 15 minutes interval.
In the block interval demand method, select a block of time that the power meter uses for the demand
calculation. You can choose how the power meter handles the block of time (interval). 2 different modes
are possible:
Fixed block - Select an interval from 1 to 60 minutes (in 1 minute increments). The power meter
calculates and updates the demand at the end of each interval.
Sliding block - Select an interval from 1 to 60 minutes (in 1 minute increments).
For demand intervals less than 15 minutes, the value is updated every 15 seconds. For demand
intervals of 15 minutes and greater, the demand value is updated every 60 seconds. The power meter
displays the demand value for the last completed interval.
The following figures illustrate the 2 ways to calculate demand power using the block method. For
illustration purposes, the interval is set to 15 minutes.
Peak Demand
In nonvolatile memory, the power meter maintains a maximum operating demand values called peak
demand. The peak is the highest value (absolute value) for each of these readings since the last reset.
You can reset peak demand values from the power meter display. You should reset peak demand after
changes to basic power meter setup such as CT ratio or power system configuration.

DOCA0006EN 06/2012
Energy Readings
The power meter calculates and stores total and partial energy values for active, reactive, and apparent
energy.
You can view energy values from the display. The resolution of the energy value automatically changes
from kWh to MWh (kVAh to MVARh).
The energy values automatically resets to 0 when it reaches the limit of 1 x 106 MWh, 1 x 106 MVAh, or
1 x 106 MVARh. Manual reset of total energy is not allowed. You can reset the partial energies including
partial energy import, energy by tariff, and phase energy manually on HMI.
Energy values can be reported over communications as 64-bit signed integers. The units are always Wh,
VARh, or VAh.
The following table lists the energy readings from the power meter:

Power Quality Analysis Values

The power quality analysis values use the following abbreviations:
HC (Harmonic Content) =
H1 = Fundamental Content
THD (Total Harmonic Distortion) = HC/H1 X 100%
THD is the power analysis value and a quick measure of the total distortion present in a waveform. THD
is the ratio of harmonic content to the fundamental and provides a general indication of the quality of a
waveform. THD is calculated for both voltage and current.

Alarms Configuration
For the standard alarms, you must configure the following features by using HMI or communication:
Pickup setpoint
Trigger delay (Pickup/Dropout delay)
Dropout setpoint (Deviation percentage from pickup setpoint)
Among the standard alarms, dropout setpoint and trigger delay are common features of all the alarms.
Pickup setpoint is identical for each alarm.
For more information on power meter handling the setpoint-driven alarms, refer to the figure below.
EV1 An alarm is active. The power meter records the date, time, and value at EV1 when the pickup setpoint and time
delay are satisfied. The power meter performs any tasks assigned to the event such as operation of a digital
output, backlight flashing, and alarm symbol flashing.
EV2 An alarm is inactive when the dropout setpoint and time delay are satisfied. The power meter performs any tasks
assigned to the event such as switch off a digital output, backlight, and alarm symbol stop flashing.
NOTE: The time delay is satisfied only if during the delay, the actual value does not fall between the
pickup setpoint and dropout setpoint.
For the over energy alarm, you also need to configure the method, which refers to the energy
accumulation and detection period.
32
DOCA0006EN 06/2012
The 3 options are:

Day method: the energy accumulation starts at 8:03 A.M. every day and clears up at 8:03 A.M. the
next day.
Week method: the energy accumulation starts at 8:03 A.M. every Sunday and clears up at 8:03 A.M.
the next Sunday.
Month method: the energy accumulation starts at 8:03 A.M. on the first day of the month and clears
up at 8:03 A.M. on the first day of the next month.
When the accumulated energy pickup setpoint and time delay are satisfied, the alarm is active. When the
accumulated energy dropout setpoint and time delay are satisfied, the alarm is inactive.
View Alarm Status on HMI
The alarm status summary page includes the following items:
Tot Enable: displays total number of the alarms enabled by the user in the alarm configuration.
Tot Active: displays total number of the active alarms. One active alarm with several entries is
considered as one.
For example, over current at phase 1 creates the first entry, over current at phase 2 creates the second
entry, but the total number of the active alarms is one.
Output: refers to the association with digital output (DO).
The alarm level 2 pages list the number of entries of the active and logged alarms.
The logged alarm entries include the active alarms and the historic alarms. One alarm occurred several
times can create several active or logged entries.
The alarm level 3 page lists the detailed information of each active/log entry. When an active alarm is not
present and you enter the log entry list, it considers that you have acknowledged all the logged alarms.
Alarm Activity and History
The active alarm list holds 20 entries at a time. The list works as a circular buffer, replacing old entries
with new entries. The information in the active alarm list is volatile. When the power meter resets, this list
is reinitialized.
The alarm history log holds 20 entries of alarms that have disappeared. The log also works as a circular
buffer, replacing old entries with new entries. This information is nonvolatile.
Using an Alarm to Control a Digital Output
You can configure digital outputs as alarms. Refer to Input/Output Capabilities (see page 34) for more
information.

DOCA0006EN 06/2012
Digital Inputs (PM3255)

The power meter can accept 2 digital inputs designated as DI1 and DI2.
The digital inputs have 4 operating modes:
Normal Input Status: use for simple ON/OFF digital inputs. The digital inputs can be OF or SD signals
of a circuit breaker.
Multi-tariff Control: you can control tariff either through communication, the internal clock or by 1 or 2
tariff inputs. Tariff control through the tariff inputs is performed by applying a proper combination of ON
or OFF signal to the inputs. Each combination of ON or OFF signal results in the power meter
registering the energy in a particular tariff register. Refer to the table below for input coding.
Input Metering: you can configure the meter in input metering modes to collect the pulses for WAGES
application. To activate this function, set the input metering pulse frequency (pulse/unit). The meter
counts the number of pulses and calculates the number of unit. Pulse width or pulse stop less than
10 milliseconds is invalid for pulse counting.
Energy Reset: energy reset function resets partial energy, energy by tariff, and energy by phase.
Reset is activated by an ON signal lasting for over 10 milliseconds.
The following table describes the input coding in binary format:

Input Voltage
Active Tariff
Meter with 4 tariffs:

DI1/DI2 = OFF/OFF
Tariff 1 active
DI1/DI2 = OFF/ON
Tariff 2 active
DI1/DI2 = ON/OFF
Tariff 3 active
DI1/DI2 = ON/ON
Tariff 4 active
Meter with 2 tariffs (always associated with DI1, and DI2 can be left floating or
configured as other mode):
DI1 = OFF
Tariff 1 active
DI1 = ON
Tariff 2 active
Pulse Output (PM3210)

Pulse output is used for active energy pulse output only. You can configure the pulse frequency
(pulse/kWh) and the pulse width. The minimum pulse width is 50 ms. The pulse stop is equal or longer
than the pulse width. The pulse output indicates the primary energy consumption considering transformer
ratios. You should set a proper value of pulse frequency and pulse width to avoid pulse missing due to
over-counting.
Digital Outputs (PM3255)
The power meter has 2 solid state relay outputs (DO1 and DO2). The relay outputs have 3 operation
modes:
Alarm: the output is controlled by the power meter in response to an alarm condition. The output turns
On (relay closed) when at least one alarm is active. The output turns Off (relay open) when the alarm
is deactivated.
Energy Output: you can use DO1 only for active energy pulse output and DO2 only for reactive energy
pulse output. You can configure the pulse frequency (pulse/kWh or pulse/kVARh) and the pulse width.
Disable: the digital output function is disabled.

Presentation
The power meter provides multi-tariff energy accumulation. It supports up to 4 tariffs.
The tariff switching has the following 3 kinds of control modes:
Digital input
Communication
Internal RTC
You can configure the control mode by using HMI (all the 3 modes) or by using communication (not for
RTC).
Command number 2060 is used to configure the control mode by communication. Refer to Modbus
communication (see page 61) for more details.
The following table presents the rules to change multi-tariff control mode by Modbus command:
From

DI Control Mode (PM3255)

In the DI control mode, the tariff switching is triggered by the change in input status of DI. Refer to Digital
inputs (see page 35) for more details.
NOTE: If you change DI mode to other operation modes (normal input status, input metering, or energy
reset) while multi-tariff control mode is in DI control mode, the multi-tariff function is automatically
disabled.
NOTE: If you change multi-tariff control mode to other control modes (communication or internal RTC)
while DI is configured for multi-tariff function, the DI operation mode automatically changes to normal
input status.
Communication Control Mode (PM3250, PM3255)
In the communication control mode, the tariff switching is triggered by command number 2008. Refer to
Modbus communication (see page 61) for more details.
RTC Control Mode
In RTC control mode, the tariff switching is triggered by the real time clock.
You can configure RTC control mode by using HMI. The configuration includes the selection of schedule
mode and the setup of 1 or 2 schedulers depending on the schedule modes.
The 2 schedule modes for RTC trigger are:
Day mode: weekdays and weekend share the same peak and peak-off duration and only 1 scheduler
should be set.
Week mode: the tariff management of weekdays and weekends are controlled separately. Hence, 2
schedulers should be set.
Weekdays
Weekend
Day mode
Week
mode
A scheduler supports maximum 4 time segments (Ta, Tb, Tc, and Td) for maximum 4 tariffs (T1, T2, T3,
and T4). You can assign Ta, Tb, Tc, or Td to any tariff provided that any adjacent time segment has
different tariff. A valid scheduler should always start from Ta segment and skipping the intermediate
segment is not allowed.
DOCA0006EN 06/2012
37
In the setup of a scheduler, you should define the tariff switching time and the target tariff rate from the
switching time. In the application, when the set switching time reaches, the current tariff rate switches to
the target rate automatically.

The power meter provides power demand log and energy log. It stores all these logs in nonvolatile
memory of the power meter. Power demand log and energy day log can be read as a log file. The 3 types
of energy log can be read as registers.
The following table lists the maximum number of entries of each log:

Power Demand Log

Total active power demand value is logged. You can configure the power demand log only on HMI by
enabling the function and selecting the log interval. The interval options include 10 minutes, 15 minutes,
20 minutes, 30 minutes, and 60 minutes. The maximum number of power demand log is 4608, which is
equivalent to maximum 32 days for 10 minutes log interval or maximum 192 days for 60 minutes log
interval. Each entry includes log time (4 registers) and log data (2 registers) and the total number of
register is 4608*6= 27648.
The demand log entry structure is shown in the following table:
Log Entry
Log date/time
4 Registers
Demand value
2 Registers
The demand log file is circular. If the number of log days exceeds the maximum, it overwrites the log data
of the oldest day.
NOTE: The overwriting unit is day, not entry. This means if overwriting happens, it erases the entire log
of the oldest day along with the oldest entry.
With ION Enterprise, you can view and save the power demand log file to a disk.
Special Notes for Power Demand Log
If date/time is not set by the user after date/time resets due to previous power interruption or the
inoperable RTC (diagnosis code #205 or #207 is reported), new entries are not generated in the
demand log.
If you change date/time, all logged entries with log date/time after the new date/time are erased.
For example, some entries were logged in October 20, 2012, if you change the date of the meter to
October 19, 2012 by mistake, the entries of October 20, 2012 are erased.
If you change the log interval option, the demand log system is reset and all logged entries are erased.
Energy Log
The meter also has the log for accumulated active energy.
The energy log entry structure is shown in the following table:
Log Entry
Log date/time
4 Registers
Energy value
4 Registers
The 3 log types are:

Day: the log interval is 1 day. The logging occurs at 8:03 A.M. every day and the accumulated active
energy for the previous 24 hours is logged.
Week: the log interval is 1 week. The logging occurs at 8:03 A.M. every Sunday and the accumulated
active energy for the previous week is logged.
Month: the log interval is 1 month. The logging occurs at 8:03 A.M. on the first day of each month and
the accumulated active energy for the previous month is logged.
You can configure the energy log only by HMI. The day log, week log, and month log are enabled or
disabled together during the configuration. However, the energy accumulation always starts from the
fixed log time instead of the time of log enabled.
With ION Enterprise, you can view and save the energy day log file to a disk. You can also access day
log, week log, and month log by reading the registers.
Special Notes for Energy Log
40
If the date/time is not set by the user after the date/time resets due to previous power interruption,
energy keeps accumulating. After the date/time is set and the log time is reached, all the accumulated
energy is written into the log.
If you reset the date, the logged entries with log date after the reset date are not erased.
When the log time is reached, the meter checks the enable/disable status of the energy log. The meter
logs the accumulated energy if the status is enable and discards if the status is disable. The
accumulated energy resets to 0.
The energy log is circular. If the number of the log entries exceeds the maximum, the oldest log entries
are overwritten.

Register Format in Power Factor
Each power factor (PF) value occupies 1 floating point register. The power meter display interprets the
register format according to the PQS Coordinate System chart. The PQS Coordinate System chart uses
the power factor register value to provide information on leading or lagging power factor and current, and
also energy import or export.
Power Factor (PF): Difference between the total power and the portion of total power that does the
useful work. The ratio of Active (P) power to Apparent (S) power (kW/kVA).
True Power Factor: Includes harmonic content.
Leading PF: Active (P) and Reactive (Q) power are flowing in opposite directions.
Lagging PF: Active (P) and Reactive (Q) power are flowing in same directions.
Leading Current (I): Current is leading voltage up to 180 .
Lagging Current (I): Current is lagging voltage up to 180 .
The PQS Coordinate System chart quadrants are based on the IEC convention.
DOCA0006EN 06/2012
101
Determining a Power Factor

To determine a power factor, proceed as follows:
Step
Action
Get the register value.
Use the register value to determine in which quadrant the system is operating.
NOTE: The quadrant determines lead/lag for power factor and current.
Use the register value to determine the flow of active power:

A positive value indicates active/apparent energy import.
A negative value indicates active/apparent energy export.
Use the register value to determine the flow of reactive power:

-2 < PF register < -1, 0< PF register < 1 indicates reactive energy import.
-1< PF register < 0, 1< PF register < 2 indicates reactive energy export.
Use the register value to determine power factor:

If the register value is within -1 to +1, the register value is the power factor
value.
If the register value is within -1 to +1, the power factor value is derived
differently for active energy import and active energy export systems:
for active energy import: PF = 2 - (the register value)
for active energy export: PF = -2 - (the register value)
For example:
Register value = 0.999: Apparent power is in quadrant 1, current (I) is
lagging, and active energy is imported to the customer load with a lagging
power factor of 0.999.
Register value = -1.1: Apparent power is in quadrant 2, current (I) is lagging,
and active energy is exported by the customer load with a leading power
factor of -0.9 (PF = (-2) - (-1.1)).
Register value = -0.986: Apparent power is in quadrant 3, current (I) is
leading, and active energy is exported by the customer load with a lagging
power factor of 0.986.
Register value = 1.14: Apparent power is quadrant 4, current (I) is leading,
and active energy is imported to the customer with a leading power factor
of 0.86 (PF = 2 - 1.14).
