The meter has a simple user interface that allows you to view numerous
measurement parameters by scrolling through different display pages. The numeric
LED display shows up to three parameters at a time. Small rectangular or triangular
LEDs at right and below the display indicate the displayed parameters and their
measurement units.
The display layout may change depending on the meter type and mode of
operation. There are three modes of display operation: data display, status display,
and programming mode display.
Load Bar Graph
Load Bar Graph
Load Bar GraphLoad Bar Graph
The load bar graph displays the amount, in percent (40% to 110%), of the present current
load with respect to user-defined nominal load current. The reference nominal current can
be set up in amps through the Display Setup menu. If it is set to 0 (default), the current load
is referenced to the specified CT primary current.

Energy Pulse LED
Energy Pulse LED
Energy Pulse LEDEnergy Pulse LED
The PowerSmart+ Advanced PQM has a red “Energy Pulse” LED. It flashes at a
constant rate when a load is applied to the meter. There are two modes of LED
operation: normal and test. In normal mode, the LED pulses indicate imported Wh at
a rate of 1,000 pulses per kWh. In test mode, the LED pulses indicate either
imported Wh, or imported (inductive) varh at a rate of 10,000 pulses per kWh/kvarh.
The energy test mode can be enabled through the Display Setup menu. When in
test mode, the energy and demand accumulators do not account for consumed
energy.
Port Activity LEDs
Port Activity LEDs
Port Activity LEDsPort Activity LEDs
The meter has two yellow LEDs “COM1” and “COM2”, which indicate activity on the
two communication ports. The port’s LED flashes when the port is receiving or
transmitting data. With the Ethernet option, the “COM1” LED flashes constantly
regardless of the port activity.
When the display module is connected remotely through a 3-wire RS-485 interface, the
“COM1” LED indicates the display port activity, while the “COM2” LED is not operational.
Navigation Buttons

Measurement Units
Currents are always displayed in amperes with two decimal places.
Measurement units for voltage and power depend on the connection scheme of the
meter:
The small round “Kilo” and “Mega” LEDs light up showing the appropriate
measurement units for a displayed page.
Primary and Secondary Volts
Volts can be displayed in primary (default) or secondary units. The volts display
mode can be changed through the Display Setup menu.
• When direct wiring is used, voltages are displayed in volts with
one decimal place, and power in kilowatts with three decimal
places.
• When wiring via PT is used, for the PT ratio up to and including
4.0, voltages are displayed in volts, and power in whole kilowatts
• For the PT ratio above 4.0, voltages are displayed in kilovolts,
and power in megawatts with three decimal places.

Phase Power Readings
In configurations with the neutral wire, in addition to total three-phase powers, the meter
can show per-phase power readings. By default, they are disabled. See Display Setup on
how to enable per-phase power readings in your meter.
Fundamental Component
The meter can display total power factor and active power for the fundamental
component if it is enabled through the Display Setup menu. Whenever phase power
readings are allowed, the PowerSmart+ Advanced PQM also displays per-phase
power factor and active power for the fundamental component.
Auto Return
If no buttons are pressed for 30 seconds while the display Auto Return option is
enabled, the display automatically returns to the main screen from any other
measurement display or programming mode.
The Auto Return option can be enabled through the Display Setup menu
Auto Scroll
If no buttons are pressed for 30 seconds while in the common measurements

follows:
1. When the reactive power calculation mode is selected, active and reactive
powers are measured directly and apparent power is calculated as:

QPS +=
This mode is recommended for electrical networks with low harmonic distortion,
commonly with THD < 5% for volts, and THD < 10% for currents. In networks with
high harmonics, the following method is preferable.
2. When the non-active power calculation mode is selected, active power is
measured directly, apparent power is taken as product S = V x I, where V and I are
the RMS volts and amps, and reactive power (called non-active power) is calculated
as:

If the daylight savings time option is disabled, you need to manually adjust the
device clock for daylight savings time.
Time Synchronization Pulses
External time synchronization pulses can be delivered through one of the digital inputs. If a
digital input is selected as the time synchronization source, the edge of an external pulse
adjusts the device clock at the nearest whole minute. The time accuracy could be affected
by the debounce time of the digital input, and by the operation delay of the external relay.

The PowerSmart+ Advanced PQM can be provided with two optional analog inputs
with options for 0-1mA, ±1mA, 0-20mA or 4-20mA input currents, depending on the
order. The 0-1mA and ±1mA inputs can accept 100% overload currents, i.e., can
actually measure currents in the range of 0-2 mA and ±2mA.
The meter automatically converts the analog input readings received from the
analog-to-digital converter to the user-defined engineering scale and shows the
input values in true engineering units, for example, in volts, amps, degrees, with the
desired resolution.
To configure the Analog Inputs in your device, select General Setup from the Meter

Scaling ±1 mA Analog Inputs
For directional ±1 mA analog inputs, you should provide only the engineering scale for the
+1 mA input current. The engineering scale for the 0 mA input current is always equal to
zero. The device does not allow you to access this setting. Whenever the direction of the
input current is changed to negative, the device automatically uses your full engineering
scale settings for +1 mA with a negative sign.
Scaling Analog Inputs for 0-2 mA and ±2 mA
The input scales for 0-1 mA and ±1 mA analog inputs are always programmed for 0 mA
and +1 mA regardless of the desired input range. If you want to use the entire input range
of 2 mA or ±2 mA, set the analog input scales in your device as follows:
0000----2 mA
2 mA: set the 1 mA scale to 1/2 of the required full scale output for uni-directional
2 mA2 mA
parameters, and set the 0 mA scale to the negative full scale and the 1 mA scale to zero for
bi-directional parameters.
±±±±2 mA
2 mA: set the 1 mA scale to 1/2 of the required full-scale output for both uni-directional
2 mA2 mA
and bi-directional parameters.
For example, to convert voltage readings from the analog transducer that transmits
them in the range of 0 to 2 mA to the range 0 to 120V, set the full range for the
+1 mA analog input to 60V; then the 2 mA reading is scaled to 120V.

When programming scales for non-directional analog outputs with a 0-1mA, 0-20mA or
4-20mA current option, you can change both zero and full engineering scales for any
parameter. The engineering scale need not be symmetrical.
Scaling Directional Power Factor
The engineering scale for the signed power factor emulates analog power factor meters.
The power factor scale is -0 to +0 and is symmetrical with regard to ±1.000 (-1.000 ≡
+1.000). Negative power factor is scaled as -1.000 minus measured value, and nonnegative power factor is scaled as +1.000 minus measured value. To define the entire
power factor range from -0 to +0, the default scales are specified as -0.000 to 0.000.
Scaling ±1 mA Analog Outputs
Programming engineering scales for directional ±1mA analog outputs depends on
whether the output parameter represents unsigned (as volts and amps) or signed
(as powers and power factor) values.
If the output value is unsigned, you can change both zero and full engineering
scales.
PowerSmart+ Advanced Power Quality Meter 69
Chapter 4 Power S O F T W A R E
If the parameter represents a signed (directional) value, you should provide only the
engineering scale for the +1 mA output current. The engineering scale for the 0 mA output
current is always equal to zero for all values except the signed power factor, for which it is
set to 1.000 (see “Scaling Directional Power Factor” above). The device does not allow you
access to this setting if the parameter is directional. Whenever the sign of the output
parameter is changed to negative, the device automatically uses your full engineering scale
settings for +1 mA with a negative sign.
Scaling Analog Outputs for 0-2 mA and ±2 mA
The output scales for 0-1 mA and ±1 mA analog outputs are programmed for 0 mA and +1
mA regardless of the desired output current range. To use the entire output range of 2 mA
or ±2 mA, set the analog output scales in your device as follows:
0000----2 mA
2 mA: set the 1 mA scale to 1/2 of the required full scale output for uni-directional

bi-directional parameters.
±±±±2 mA
2 mA: set the 1 mA scale to 1/2 of the required full-scale output for both uni-directional
2 mA2 mA
and bi-directional parameters.
For example, to provide the 0 to 2 mA output current range for volts measured by the meter
in the range of 0 to 120V, set the 1 mA scale to 60V; then the 120V reading will be scaled
to 2 mA.

Using Periodic Timers
Using Periodic Timers
Using Periodic TimersUsing Periodic Timers
The PowerSmart+ Advanced PQM provides two programmable interval timers that can be
used for periodic recording and triggering operations on a time basis via the Control
Setpoints. When a timer interval expires, the timer generates an internal event that can
trigger any setpoint (see Using Control Setpoints).
G E N E R A L M E T E R S E T U P
To configure the device timers, select General Setup from the Meter Setup menu,
and then click on the Periodic Timers tab.
To run a periodic timer, specify a non-zero time period for the timer. The time period
can be set from 1 to 9999 seconds.
To stop a timer, set the time period to zero.
Using Control Setpoints
Using Control Setpoints
Using Control SetpointsUsing Control Setpoints
The PowerSmart+ Advanced PQM has an embedded logical controller that runs
different actions in response to user-defined internal and external events. Unlike a
PLC, the meter uses a simplified programming technique based on setpoints that
allows the user to define a logical expression based on measured analog and digital
values that produce a required action.
The meter provides 16 control setpoints with programmable operate and release
delays. Each setpoint evaluates a logical expression with up to four arguments
using OR/AND logic. Whenever an expression is evaluated as “true”, the setpoint
performs up to four concurrent actions that can send a command to the output
relays, increment or decrement a counter, or trigger a recorder.
The logical controller provides very fast response to events. The scan time for all
setpoints is 1/2 cycle time (8.8 ms at 60Hz and 10 ms at 50 Hz).
To program the setpoints, select General Setup from the Meter Setup menu, and
then click on the Control/Alarm Setpoints tab.

Using Logical Expressions
Logical operators OR/AND are treated in a simplified manner. They have no specific
priority or precedence rules.
Any trigger condition bound to the logical expression by the OR operator and
evaluated as “true” will override any preceding condition evaluated as “false”.
Similarly, any trigger condition evaluated as “false” and bound by the AND operator
will override any condition evaluated before it as “true”.
To avoid confusion, it is recommended not to alternate different logical operators in
one expression. Instead, bring all conditions that use the same logical operator
together at one side of the expression, and the others - at the opposite side.
To explicitly override all other conditions with the critical trigger, put it at the end of
the expression using the OR operator if you want the setpoint to be operated
PowerSmart+ Advanced Power Quality Meter 73
Chapter 4 Power S O F T W A R E
anyway when the trigger condition is asserted, and with the AND operator, if the
setpoint should not be operated while the critical trigger is not asserted.
Using Numeric Triggers
For numeric (analog) triggers, a setpoint allows you to specify two thresholds for
each trigger to provide hysteresis (dead band) for setpoint operations. The Operate
Limit defines the operating threshold, and the second Release Limit defines the
release threshold for the trigger. The trigger thresholds are specified in primary
units.
If you do not want to use hysteresis for the trigger, set the Release Limit to the same
as the Operate Limit.
Using Binary Triggers
Binary (digital) triggers, like digital inputs, relays, or internal static and pulsed
events, are tested for ON (closed/set) or OFF (open/cleared) status.
The binary events are divided into two types: static events and pulsed events. Static
events are level-sensitive events. A static event is asserted all the time while the
corresponding condition exists. Examples are digital inputs, relays and event flags.
Pulsed events are edge-sensitive events with auto-reset. A pulsed event is
generated for a trigger only once when a positive transition edge is detected on the
trigger input. The examples of pulsed events are pulse inputs (transition pulses on
the digital inputs), internal pulsed events (energy pulses and time interval pulses),
and events generated by the interval timers. The logical controller automatically
clears pulsed events at the end of each scan, so that triggers that used pulsed
events are prevented from being triggered by the same event once again.
G E N E R A L M E T E R S E T U P
Using Event Flags
The PowerSmart+ Advanced PQM provides 8 common binary flags, called event
flags, which can be individually set, cleared and tested through setpoints and via
communications.
Event flags can be used in different applications, for example, to transfer events
between setpoints in order to expand a logical expression or a list of actions that
have to be done for a specific event, or to externally trigger setpoint actions from the
SCADA system or from a PLC through communications.
Using Interval Timers
The PowerSmart+ Advanced PQM provides four interval timers that are commonly
used for periodic recording of interval data at the time of the fault or in the presence
of other events detected by a setpoint. The timers can be programmed to generate
periodic events at user-defined intervals (see Using Periodic Timers).
Interval timers are not synchronized with the clock. When you run a timer, it
generates a pulsed event that can trigger a setpoint if you have put the timer into a
list of the setpoint triggers. When the setpoint event is asserted, the timer is
restarted, and then generates the next event when the timer interval expires.
If you want to record interval data at predefined intervals without linking to other
events, just select a timer as a setpoint trigger and specify a data log file you want to
use for recording, in the setpoint actions list. If you want the periodic data to be
recorded in presence of a specific event, select triggers that will identify your event,
and then add the timer at the end of the trigger list using the AND operator.
Using Time Triggers
If you want the setpoint actions to be synchronized with the clock, for example, to
provide synchronous recording interval data each 15 minutes or each hour, or to
output time pulses through relay contacts, use the time triggers that generate static
events synchronized to the device clock.
74 PowerSmart+ Advanced Power Quality Meter
Chapter 4 Power S O F T W A R E
You can exercise the default setting for Setpoint #1 in your device as an example of
using time triggers. The setpoint is pre-programmed for data profiling at 15-minute
intervals using data logs #1 and #2.
Delaying Setpoint Operations
Two optional delays can be added to each setpoint to extend monitoring setpoint
triggers for a longer time before making a decision on whether the expected event
occurred or not. When a delay is specified, the logical controller will change the
setpoint status only if all conditions are asserted for a period at least as long as the
delay time.
Note that you cannot use delays with pulsed events since they are cleared
immediately and will no longer exist on the next setpoint scan.
Using Setpoint Events and Actions
When a setpoint status changes, i.e., a setpoint event is either asserted or deasserted, the following happens in your device:
The new setpoint status is logged to the setpoint status register that can be monitored
through communications from the SCADA system or from a programmable controller in
order to give an indication on the expected event.
The operated setpoint status is latched to the setpoint alarm latch register accessible
through communications. The register holds the last setpoint alarm status until it is
explicitly cleared through communications.
Up to four programmable actions can be performed in sequence on setpoint status
transition when a setpoint event is asserted.
Generally, setpoint actions are performed independently for each setpoint and can
be repeated a number of times for the same target. The exceptions are relay
operations, data logging and waveform logging that are shared for each separate
target between all setpoints using an OR scheme.
A relay output is operated when one of the setpoints linked to the relay is activated
and will stay in the operated state until all of these setpoints are released (except for
latched relays that require a separate release command to be deactivated).
Data logging and waveform logging directed to the same file are done once for the
first setpoint among those that specify the same action, guaranteeing that there will
not be repeated records related to the same time.
G E N E R A L M E T E R S E T U P
Recording Setpoint Events
Time-tagged setpoint events can be recorded to the device Event log if you put a
corresponding action into the setpoint action list. The Event recorder will log any
setpoint transition event: both when the setpoint is operated, and when it is
released. The Event recorder will put into a log file a separate record for each active
trigger caused a setpoint status transition, and a separate record for each action
done on the setpoint activation (except for data logging actions that are not
recorded to the Event log).

Waveform log files are organized as multi-section files that store data for each
recording channel in a separate section. A waveform log file stores up to 6 channels
simultaneously: three voltage and three current channels.
A single channel waveform record contains 512 points of the sampled input signal. If
a waveform log is configured to record more samples per event than a single record
can hold, the waveform recorder stores as many records per event as required to
record the entire event. All waveform records related to the event are merged in a
series and have the same series number, so they can be plotted together.
The PowerSmart+ Advanced PQM supports two waveform files that record
waveforms at three programmable sampling rates: 32, 64 or 128 samples per cycle.
To configure a waveform log file:

The number of records in the waveform log file needed to store one waveform event
(series) is defined as follows:
Number of Records per Series = Sampling Rate (Samples per Cycle) x Number of Cycles

The total number of records you must allocate to store the required number of events
(series) is defined as follows:
Number of Records = Number of Records per Series x Number of Series
For example, if you want to record a 64-cycle waveform sampled at a rate of 32 samples
per cycle, the number of records required for one waveform series would be:
Number of Records per Series = (32 x 64)/512 = 4.
If you want to allocate space sufficient to store 20 waveform events (series), you should set
up the waveform log file for 4 x 20 = 80 records.

The EN50160 European standard “Voltage characteristics of electricity supplied by public
distribution systems” issued by CENELEC defines the main physical characteristics of
electric energy supplied by low and medium voltage public distribution systems under
normal operating conditions.
The voltage characteristics are evaluated using a statistical approach. The standard and its
referenced publications specify for each voltage characteristic:
Method of evaluation
Integrating interval for a single measurement
Observation period
Statistical indication of the probability of not exceeding a specified limit
Standard compliance limits or indicative values within which any customer can expect the
voltage characteristics to remain
Compliance Limits
For some voltage characteristics, the standard provides definite limits that can be complied
with for most of the time considering the possibility of relatively rare excursions beyond
these limits. Limits are set with a view to compliance for a percentage of the observation
time, e.g. 95% of the observations in any period of one week.
The following table gives the characteristics for which definite limits have been specified by
the standard.

Evaluation Counters and Evaluation Period
The PowerSmart+ Advanced PQM uses a set of the evaluation counters for
collecting EN50160 statistics within a specified evaluation period.
The evaluation period is the period of time within which the meter collects statistical
evaluation data. Supply voltage characteristics can be evaluated on a weekly or daily
basis. The evaluation period being normally preset in your meter to a week can be changed
via the EN50160 Advanced setup.
At the end of the evaluation period, the meter records collected statistical evaluation data to
a log file, and then clears the evaluation registers and counters so that each evaluation
period’s statistics is stored in a separate record.
You can upload and view the online statistics data via Power Software reports, using data
collected since the beginning of the present evaluation interval. You can also manually
clear the present contents of the counters though Power Software before starting your
EN50160 evaluation.
Observation Period
The observation period is the period of time within which the voltage characteristics shall
be assessed to ensure compliance with the standard. The observation periods declared by
the EN50160 may differ for characteristics for which compliance limits are specified in the
standard, usually one week, and for those for which only indicative values are provided,
usually one year.
The EN50160 compliance reports produced by Power Software provide correct weekly and
yearly observation statistics regardless of the evaluation periods used for collecting data.
Whenever needed, Power Software will aggregate records within a number of the
evaluation intervals to provide correct observation periods. Some of the characteristics, like
rapid voltage changes or mains signaling voltage, may require daily assessments. If you
intend to use daily-evaluated voltage characteristics, select the daily evaluation period via
the EN50160 Advanced setup.
EN50160 Compliance Statistics Log
Data log file #9 is automatically configured in the PowerSmart+ Advanced PQM for
recording EN50160 compliance statistics. Appendix E lists parameters recorded to the file.
The file is arranged as a multi-section data log file where each voltage characteristic
statistics is stored in a separate section. Along with EN50160 compliance statistics
PowerSmart+ Advanced Power Quality Meter 87
Chapter 4 Power S O F T W A R E
recorded at the end of each evaluation period, file also contains data that may be useful for
trouble-shooting power quality problems for non-compliant voltage characteristics.
You can upload and view the EN50160 compliance statistics data via Power Software
reports or via common Power Software data logs views.
EN50160 Harmonics Survey Log
Data log file #10 is automatically configured in the PowerSmart+ Advanced PQM for
recording harmonics survey statistics on a weekly or daily basis. You can see parameters
recorded to the file in Appendix E. The file stores maximum THD (total, odd and even
harmonics) and maximum harmonic voltages up to order 50 collected within each
evaluation period.
Harmonics survey is normally intended for trouble-shooting harmonic problems throughout
electrical networks. It can be separately disabled or enabled in your meter via the EN50160
Advanced Setup. The evaluation period for harmonics survey can be selected
independently from the EN50160 compliance evaluation.
You can upload and view the harmonics survey data collected by your device via Power
Software reports or via common Power Software data logs views.
EN50160 Power Quality Event Log
The PowerSmart+ Advanced PQM provides the EN50160 Power Quality (PQ) recorder that
can detect EN50160 incidents and record each individual power quality event to the log file
with the start and end timestamps and a fault magnitude. It may be useful for troubleshooting problems throughout the electrical network, for example, to identify and locate the
source of a power quality event and to select an appropriate solution.
The EN50160 power quality report can be uploaded and viewed via Power Software (see
Viewing EN50160 Power Quality Event Log). Transient overvoltages and short-duration
voltage dips and temporary overvoltages recorded to the file can also be viewed in Power
Software as magnitude/duration pairs on the well-known ITIC curve chart for assessing the
minimum equipment immunity.
The PQ recorder is programmable to trigger the waveform recorder to record the fault
waveforms before, during and after the PQ event for detailed event analysis.

Methods of EvaluationMethods of Evaluation
This section describes methods used by the PowerSmart+ Advanced PQM for evaluating
supply voltage characteristics to ensure compliance with the standard.
Frequency Variations
Method of Evaluation
The basic frequency measurement is the mean value of the frequency over fixed time
intervals of 10 seconds under normal operating conditions.
A frequency variation is not evaluated if the supply voltage crosses a voltage tolerance limit
(±15% Un).
Target Values
The ranges of frequency variations given in the EN50160 are:
50Hz±1% for 95% of a week
50Hz±1% for 99.5% of a year
50Hz+4/-6% for 100% of the time
The same limits are used for 60Hz systems. The frequency compliance limit can be
programmed in the meter in percent of the nominal power frequency via the EN50160 PQ
Recorder setup.
88 PowerSmart+ Advanced Power Quality Meter
Chapter 4 Power S O F T W A R E
Supply Voltage Variations
This characteristic defines slow variations of steady state supply voltage magnitude.
Method of Evaluation
The basic supply voltage magnitude measurement is the RMS value of the steady state
voltage over a period of 10 minutes under normal operating conditions.
A voltage variation is not evaluated if the supply voltage crosses a voltage tolerance limit
(±15% Un).
Target Values
The range of voltage variations given in the EN50160 is:
±10% Un for 95% of a week
The supply voltage compliance limit can be changed in the meter via the EN50160 PQ
Recorder setup.
Rapid Voltage Changes
Rapid voltage changes are sudden but relatively weak voltage variations between two
steady state voltage levels.
Method of Evaluation
Evaluation of rapid voltage changes is made on an hourly basis. The RMS voltage is
evaluated over 3-second time integration intervals. The meter establishes the maximum
difference of the RMS voltage between two intervals selected from three 3-second
consecutive intervals and compares it with the target compliance limit.
A rapid voltage change is not classified if it crosses a voltage tolerance limit (±10% Un), as
it would be considered a voltage dip or a temporary overvoltage.
E N 5 0 1 6 0 E V A L U A T I O N A N D
Target Values
The maximum rate of rapid voltage changes in normally once per hour or less. For voltage
variations repeating more than once an hour, amplitude is limited by the flicker index. The
maximum rate of rapid voltage changes in variations per hour can be changed in the meter
via the EN50160 Advanced Setup. The target magnitude limit of rapid voltage changes can
be programmed in the meter via the EN50160 PQ Recorder setup.
Under usual operating conditions the magnitude of rapid voltage changes (once per hour or
less) should generally not exceed 5% of nominal voltage in LV networks, and 4% in MV
networks. In some circumstances, like in systems where equipment switching must be
carried out to meet supply system or load requirements, it can reach 10%Un in LV
networks, and 6%Un in MV networks.
Flicker
Flicker expresses the visual discomfort caused by repetitive changes of brightness in
lightning subjected to fluctuations of the supply voltage. Flicker is indicated by the longterm flicker severity parameter Plt, which is evaluated every 2 hours.
Method of Evaluation
The basic measurement is the short-term flicker severity indicator Pst, evaluated each 10
minutes by instrumentation complying with IEC 61000-4-15. The indicative long-term flicker
severity Plt is evaluated from 12 consecutive Pst values. For testing purposes, the Pst
period can be temporarily changed in the meter in the range of 1 to 10 minutes via the
EN50160 Advanced Setup.
Pst values are not classified during intervals when the supply voltage magnitude exceeds a
voltage tolerance limit (±15% Un) or is affected by voltage dips with depth more than 15%
Un.
Target Values
The flicker compliance limit given in the EN50160 is:
Plt ≤ 1 for 95% of a week
PowerSmart+ Advanced Power Quality Meter 89
Chapter 4 Power S O F T W A R E
The Plt compliance limit can be changed in the meter via the EN50160 PQ Recorder setup.
Voltage Dips
A voltage dip is a sudden reduction of the RMS voltage below 90% of the nominal value,
followed by a return to a value higher than 90% of the nominal in a time varying from 10 ms
to 60 s.
Method of Evaluation
A voltage dip is classified as one polyphase event regardless of the shape and of the
number of phases affected (as per Eurelectric’s Application guide to the European
Standard EN 50160, and IEC 61000-4-30). An event can begin on one phase and end on
another phase. The fault magnitude is recorded separately for each phase involved. The
event duration is measured from the instant at which the voltage falls below the start
threshold on one of the phases to that at which it becomes greater than the end threshold
on all affected phases including a threshold hysteresis.
The basic voltage dip measurement is one-cycle RMS voltage updated each half-cycle.
The voltage dip threshold can be changed in the meter via the EN50160 PQ Recorder
setup.
Statistical Results
The PowerSmart+ Advanced PQM provides the statistical evaluation of voltage dips using
the classification established by UNIPEDE. Dips are classified by residual voltage
magnitude and duration as shown in Appendix E.
E N 5 0 1 6 0 E V A L U A T I O N A N D
Indicative Values
Under normal operating conditions the expected number of voltage dips in a year may be
from up to a few tens to up to one thousand. The majority of voltage dips have a duration
less than 1 s and a depth less than 60%.
Voltage Interruptions
Voltage interruptions correspond to temporary loss of supply voltage on all phases lasting
less than or equal to 3 minutes in the event of short interruptions, and more than 3 minutes
for long interruptions.
Method of Evaluation
The voltage interruption is detected when the voltages on all phases fall below the
interruption threshold (as per IEC 61000-4-30) specified by the EN50160 at a level of
1%Un. The interruption threshold can be changed in the meter via the EN50160 PQ
Recorder setup.
The basic voltage measurement is one-cycle RMS voltage updated each half-cycle.
Statistical Survey
The PowerSmart+ Advanced PQM provides the statistical evaluation of voltage
interruptions using the classification recommended by Eurelectric’s Measurement guide for
voltage characteristics.
Interruptions are classified by duration as shown in Appendix E.
Indicative Values
Under normal operating conditions the expected number of short voltage interruptions in a
year may be from up to a few tens to up to several hundreds. Short interruptions generally
last less than a few seconds.
The annual frequency of long interruptions may be less than 10 or up to 50 depending on
the area.
Temporary Overvoltages
Temporary overvoltages are sudden rises of the voltage RMS value of more than 110% of
nominal voltage. Temporary overvoltages may last between 10 milliseconds and one
minute.
90 PowerSmart+ Advanced Power Quality Meter
Chapter 4 Power S O F T W A R E
Method of Evaluation
A temporary overvoltage is classified as one polyphase event regardless of the shape and
of the number of phases affected (as per IEC 61000-4-30). An event can begin on one
phase and end on another phase. The fault magnitude is recorded separately for each
phase involved. The event duration is measured from the instant at which the voltage rises
above the start threshold on one of the phases to that at which it becomes lower than the
end threshold on all affected phases including a threshold hysteresis.
The overvoltage threshold can be changed in the meter via the EN50160 PQ Recorder
setup.
The basic voltage measurement is one-cycle RMS voltage updated each half-cycle.
Statistical Survey
The PowerSmart+ Advanced PQM provides the statistical evaluation of temporary
overvoltages using the classification recommended by Eurelectric’s Measurement guide for
voltage characteristics. Temporary overvoltages are classified by voltage magnitude and
duration as shown in Appendix E.
Indicative Values
Temporary overvoltages on the low voltage side will generally not exceed 1.5 kV RMS.
Transient Overvoltages
Transient overvoltages correspond to disturbances of very short duration, lasting typically
less than one half-cycle, i.e. a few microseconds to several milliseconds.
E N 5 0 1 6 0 E V A L U A T I O N A N D
Method of Evaluation
Transient overvoltages are detected as impulsive transients with a rise time less than 0.5
ms and duration from 150 us to ½ cycle. The impulse magnitude is evaluated by the peak
voltage value and is referenced to the nominal peak voltage (1.414 Un). The meter can
detect transient overvoltages with a magnitude of up to 700V.
Statistical Survey
The PowerSmart+ Advanced PQM provides the statistical evaluation of transient
overvoltages using the classification recommended by Eurelectric’s Measurement guide for
voltage characteristics. Transient overvoltages are classified by voltage magnitude as
shown in Appendix E.
Indicative Values
Transient overvoltages in LV systems will generally not exceed 6 kV peak, but higher
values occur occasionally.
Voltage Unbalance
This characteristic defines the magnitude and/or phase asymmetries of three-phase steady
state supply voltage.
Method of Evaluation
The basic measurement is the RMS value of the steady state voltage unbalance over a
period of 10 minutes under normal operating conditions. It is defined using the theory of
symmetrical components by the negative sequence component expressed in percent of the
positive sequence component.
Voltage unbalance is not evaluated if the supply voltage crosses a voltage tolerance limit
(±15% Un).
Target Values
The range of voltage unbalance given in the EN50160 is:
≤ 2% (≤ 3% in some areas) for 95% of a week
The voltage unbalance compliance limit can be changed in the meter via the EN50160 PQ
Recorder setup.
PowerSmart+ Advanced Power Quality Meter 91
Chapter 4 Power S O F T W A R E
Harmonic Voltage
Method of Evaluation
The basic measurements are the individual harmonic voltage distortion factors (HD) and
the total harmonic distortion factor (THD) over a period of 10 minutes under normal
operating conditions.
Harmonic voltages are evaluated by instrumentation complying with IEC 61000-4-7. All
calculations are made relative to the nominal voltage.
The THD is evaluated including all harmonics up to the order 40. Harmonic voltages are
evaluated up the order 25 since the EN50160 provides target values for individual
harmonic voltages only for orders up to 25. The highest harmonic order for evaluating
individual harmonic voltages and THD can be changed in the meter in the range of 25 to 50
via the EN50160 Advanced Setup.
Harmonic voltages are not evaluated if the supply voltage crosses a voltage tolerance limit
(±15% Un).
Target Values
The ranges of harmonic voltages given in the EN50160 are:
THD ≤ 8% for 95% of a week
Individual harmonic voltages shall be less than or equal to the values given in Table 1 in
Clause 2.11 of the EN50160 for 95% of a week.
The THD compliance limit can be changed in the meter via the EN50160 PQ Recorder
setup. The individual harmonic voltage limits can be adjusted via the EN50160 Harmonics
setup.
E N 5 0 1 6 0 E V A L U A T I O N A N D
Interharmonic Voltage
Method of Evaluation
Since the EN50160 does not specify target limits for interharmonic voltages, this feature is
normally disabled in your meter. You can enable evaluation of interharmonic voltages via
the EN50160 Advanced Setup.
The basic measurements are the individual interharmonic voltage distortion factors (HD)
and the total interharmonic distortion factor (THD) over a period of 10 minutes under
normal operating conditions.
Interharmonic voltages are evaluated by instrumentation complying with IEC 61000-4-7. All
calculations are made relative to the nominal voltage.
The highest harmonic order for evaluating individual interharmonic voltages and
interharmonic THD can be selected in the meter in the range of 25 to 50 via the EN50160
Advanced setup.
Interharmonic voltages are not evaluated if the supply voltage crosses a voltage tolerance

Target Values
The EN50160 does not provide target limits for interharmonic voltages. The ranges of
interharmonic voltages selected in the PowerSmart+ Advanced PQM are:
Interharmonic THD ≤ 2% for 95% of a week
Individual interharmonic voltages shall be less than or equal to the values given in the
following table for 95% of a week.
Interharmonic order Relative Voltage
2 0.2
3-15 1.0
16-25 0.5
92 PowerSmart+ Advanced Power Quality Meter
Chapter 4 Power S O F T W A R E
You can change the compliance limit for the interharmonic THD via the EN50160 PQ
Recorder setup. The individual interharmonic voltage limits can be changed via the
EN50160 Harmonics setup.
Mains Signaling Voltage
This characteristic defines the magnitude of the signal voltages used in some countries for
signal transmission over public supply networks. These may include ripple control signals
in a frequency range from 100 HZ to 3 kHz, and carrier wave communications signals in a
frequency range from 3 kHz to 148.5 kHz.
The PowerSmart+ Advanced PQM can evaluate ripple control signaling voltages in a
frequency range from 100 Hz to 3 kHz.
Method of Evaluation
Since evaluating signal voltages is not commonly used, this feature is normally disabled in
your meter. You can enable evaluation of signaling voltages via the EN50160 Advanced
Setup.
The PowerSmart+ Advanced PQM evaluates up to four ripple control frequencies. You can
select the required signaling frequencies via the EN50160 Advanced Setup.
The basic measurement is the magnitude of the signaling voltage over a period of 3
seconds under normal operating conditions.
Signaling voltages are not evaluated if the supply voltage crosses a voltage tolerance limit
(±15% Un).
E N 5 0 1 6 0 E V A L U A T I O N A N D
Target Values
The voltage levels given by the EN50160 in Figure 1 of Clause 2.13 are taken from the socalled “Meister-curve” which defines the maximum permissible ripple control voltages in LV
networks.
Compliance with the EN50160 requires that the 3-second mean of signal voltages
shall be less or equal to the specified limits for 99% of a day.

Basic Device Settings
The following device settings affect the EN50160 evaluation and should be checked prior to
running the EN50160 recorders.
Reference Voltage
As the general approach of the EN50160, all voltage characteristics are referenced to the
nominal voltage that shall be specified in your meter before running the EN50160 recorders
(see Basic Meter Setup). The nominal voltage refers to the line-to-neutral supply voltage in
LV networks (4LN3, 3LN3 or 3BLN3 wiring modes), and to line-to-line voltage in MV
networks (4LL3, 3LL3, 3BLN3, 3OP2, 3OP3 and 3DIR2 wiring modes).
Reference Frequency
The nominal line frequency is used as a reference for the evaluation of power frequency
variations. It should be specified in your meter before running the EN50160 recorders (see
Basic Meter Setup).
EN50160 Evaluation Limits and Options
Limits for evaluation of the EN50160 voltage characteristics can be set via the EN50160
PQ Recorder Setup and, for harmonic and interharmonic voltages, via the EN50160
Harmonics Setup (see EN50160 Harmonics Limits Setup).
The EN50160 evaluation options can be changed via the EN50160 Advanced Setup.

To configure the PQ recorder:
Select Memory/Log from the Meter Setup menu, and then click on the EN50160 PQ
Recorder tab.
Adjust thresholds and hysteresis for PQ triggers if required. The harmonic and
interharmonic voltage limits can be individually set for each harmonic order via the
EN50160 Harmonics Setup. Limits for the signaling voltage frequencies are automatically
taken from the “Meister-curve”.
Check the Enabled box for the voltage characteristics you want to be recorded to the PQ
event log. You can individually enable or disable recording PQ events related to specific
characteristics. Notice that the interharmonic voltage and mains signaling voltage
evaluation should be also enabled in the meter via the EN50160 Advanced Setup.
Disabling recording events to the PQ log does not prevent the evaluation of the voltage
characteristics and collecting the EN50160 statistics for these events.
Select the waveform logging options for PQ events.

The waveform log options allow recording waveforms both at the start and the end of a PQ
event. Since the voltage variations can last from some seconds to minutes, this allows
capturing and analyzing the voltage transitions using short time waveform recording at the
start and at the end of the voltage dip or overvoltage.
You can temporary disable the PQ recorder in your device. To enable or disable the PQ
recorder:
Check or uncheck the Recorder Enabled checkbox.

Indication of the Power Quality Events
When the PQ recorder detects a power quality fault, it generates the specific internal event
“PQ EVENT” that can be monitored through a control setpoint. The event is asserted all the
time while the fault condition exists. The “PQ EVENT” trigger is used to give a power
quality fault indication via relay contacts, or can be combined using the AND operator with
timer ticks for periodic data recording at the time of the fault to produce voltage trending
charts.

Modbus Point Mapping
The PowerSmart+ Advanced PQM provides 120 user assignable registers in the address
range of 0 to 119. You can re-map any register available in the meter to any assignable
register so that Modbus registers that reside at different locations may be simply accessed
using a single request by re-mapping them to adjacent addresses.

Chapter 4 Power S O F T W A R E
Initially these registers are reserved and none of them points to an actual data register. To
build your own Modbus register map:
Select Protocol Setup from the Meter Setup menu and click on the Modbus Registers tab.
Click on the Default button to cause the assignable registers to reference the actual default
meter register 11776 (0 through 119 are not allowable register addresses for re-mapping).
Type in the actual addresses you want to read from or write to via the assignable registers.
Refer to the PowerSmart+ Advanced PQM Modbus Reference Guide for a list of the
