Port Activity LEDs

Indicators and Controls

Numeric LED Display

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

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

The PM175 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.

Series PM175 Powermeters 31

Chapter 3 Display Operations

Port Activity LEDs

Data Display

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

The PM175 is provided with six push buttons that are normally used to navigate between different measurement displays. In programming mode, the buttons access the device setup menus and the default factory-set device settings can be changed.

Data Display

In data mode, the display is normally updated once per second; you can adjust the display update rate via the Display Setup menu.

Display Features

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:

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.

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.

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 PM175 also displays perphase power factor and active power for the fundamental component.

32 Series PM175 Powermeters

Chapter 3 Display Operations Data Display

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 display, and the Auto Scroll option is enabled in the meter, the display automatically scrolls through all available pages. The scroll interval can be adjusted through the Display Setup menu.

To stop auto scrolling, press briefly the SCROLL button.

In Data Display mode, the navigation buttons function as follows.

The MIN/MAX button switches to the Min/Max - Maximum Demands display pages. When briefly pressed again, it switches back to the common measurements display.

The PQ button switches between different power quality/harmonic displays:

Total Harmonics, Individual Voltage and Current Harmonics, and Power

Quality parameters – short-term (Pst) and long-term (Plt) flicker, and voltage and current negative sequence unbalance. When briefly pressed once again, it switches back to the common measurements display

The UP and DOWN arrow buttons, labeled by arrowheads, scroll forwards and backwards through the display pages. Pressed briefly, they move one page forward or backward. If you hold down the button the display pages are scrolled at rate of a twice per second.

Pressing both the UP and DOWN arrow buttons together returns to the first page within the current display.

The SELECT button operates once it’s released. The button has two functions:

When pressed briefly, it switches to programming mode.

When pressed together with the ENTER button for more than 5 seconds, it resets Min/Max records, maximum demands, or energies depending on the currently displayed page. If the meter is password protected, and a simple reset of data from the display is not allowed, the action has no effect.

The ENERGY button switches to the Energy display. If TOU registers are configured in the meter, you can repeatedly press this button to scroll through all available TOU registers. When briefly pressed once again, it switches back to the common measurements display

Simple Reset of Accumulated Data

When the meter is not password protected, or the simple reset of data is allowed from the display regardless of the security setting (see

Display

Setup ), the meter allows the simple “two-button’ reset of the Min/Max

registers, maximum demands, energies, and counters from the data display mode without entering the reset menu:

Chapter 4 PAS Application Software

Supplemental PAS software can be used for configuring the PM175 through communication ports, for retrieving real-time and recorded data, and for remote upgrading device firmware.

For information on how to install PAS on your PC, see the “PAS Getting

Started” guide supplied on the installation CD.

Configuration Database

To communicate with your meters, create a separate site database for each device. All communication and configuration data for your meter is stored in this database. During configuration store all setup data to the site database so that PAS recognizes device properties regardless of whether the device is online or offline.

To create a new database for your meter:

1. Select Configuration from the Tools menu, and then click the Sites button on the right-hand-side.

2. From the “Look in” box, select the directory where a new database will be stored. By default, it will be the “Sites” directory. Type a site name for your device in the “File name” box, click New, and then click OK.

3. On the Instrument Setup tab, select “PM175” in the

“Model” box. PAS automatically selects the appropriate instrument options for your meter.

4. Select a correct CT secondary current (5A or 1A) for your meter.

5. If you wish to add any comments for your meter, type them into the “Comment” box.

Setting up Communications

You can communicate with the meter via a changeable COM1 communication port, or through a second factory set serial RS-485/RS-422

COM2 port. Depending on what was ordered, your meter’s COM1 port can be equipped with an RS-232/RS-422/RS-485 serial interface, with a dial-up modem for communicating through public telephone lines, or with an

Power Calculation Modes

The power calculation mode option allows you to change the method for calculating reactive and apparent powers in presence of high harmonics. The options work as follows:

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

S = P

2

+ Q

2

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:

N = S

Daylight Savings Time

The daylight savings time option is enabled in the PM175 by default, and the default daylight savings time change points are preset for the U.S.A. When the daylight savings time is enabled, the meter automatically adjusts the device clock at 02.00 AM when daylight savings time begins/ends.

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.

Using Digital Inputs

The meter is provided with two digital inputs that can trigger the alarm/control setpoints to give an alarm on input status change, or can be linked to the energy/TOU registers to count pulses from external watt meters, or gas and water meters.

To configure them in your device, select the device site from the list box on the PAS toolbar, select General Setup from the Meter Setup menu, and then click on the Digital Inputs tab.

The debounce time is used the same for both digital inputs. If you change the debounce time for one digital input, the same debounce time is automatically assigned to the other.

Using Relay Outputs

The PM175 is equipped with two relays. Each relay can be operated either locally from the alarm/control setpoints in response to an external event, or by a remote command sent through communications, and can also be linked to an internal pulse source to produce energy pulses.

KYZ mode: the relay generates transition pulses. The relay output state is changed upon each command and remains in this state until the next command.

With normal polarity, the relay is normally de-energized in its non-active state and is energized in its active

(operated) state.

With inverting polarity, the relay is normally energized in its non-active state and is de-energized in its active

(operated) state. It is called failsafe relay operation.

Applicable for latched relays.

In non-retentive mode, the relay always returns to its non-active state upon power up.

In retentive mode, the relay status is restored to what it was prior to loss of power.

The actual pulse width is a multiple of the 1/2-cycle time rounded to the nearest bigger value.

The pause time between pulses is equal to the pulse width.

Links a pulse relay to the internal energy pulse source. The relay must be set into either pulse, or KYZ mode.

Generating Energy Pulses through Relay Outputs

To generate energy pulses through a relay output:

1. Set a relay to either pulse, or KYZ mode, and then select a polarity (active pulse edge) for energy pulses and a pulse width.

2. Select a source accumulator (type of energy) and the pulse rate for your output.

Programming Analog Inputs

General Meter Setup

The PM175 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

Scaling Non-directional Analog Inputs

For non-directional analog inputs with the 0-1mA, 0-20mA and 4-20mA current options, provide both zero and full engineering scales. Each of the scales operates independently.

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:

0-2 mA: set the 1 mA scale to 1/2 of the required full scale output for unidirectional 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: set the 1 mA scale to 1/2 of the required full-scale output for both uni-directional 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.

Programming Analog Outputs

The meter can be ordered with two optional analog outputs with options for

0-1mA, ±1mA, 0-20mA or 4-20mA output currents.

The 0-1mA and ±1mA current outputs provide a 100% overload, and actually output currents up to 2 mA and ±2mA whenever the output value exceeds the engineering scale set for the 1 mA or ±1mA.

To configure the Analog Outputs in your device, select General Setup from the Meter Setup menu, then click on the Analog Outputs tab. If you are programming your device online, analog outputs are designated as not available if they are not present in the device.

The available analog output options are described in the following table.

When you select an output parameter for the analog output channel, the default engineering scales are set automatically. They represent the maximum available scales. If the parameter actually covers a lower range,

Series PM175 Powermeters 67

Chapter 4 PAS Application Software General Meter Setup you can change the scales to provide a better resolution on the analog outputs.

68

Scaling Non-directional Analog Outputs

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 non-negative 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.

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.

Series PM175 Powermeters

Chapter 4 PAS Application Software General Meter Setup

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:

0-2 mA: set the 1 mA scale to 1/2 of the required full scale output for unidirectional 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: set the 1 mA scale to 1/2 of the required full-scale output for both uni-directional 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 Counters

The meter provides four six-digit counters that count different events.

To configure the device counters, select General Setup from the Meter Setup menu, then click on the Pulse/Event Counters tab.

Each counter is independently linked to any digital input and count input pulses with a programmable scale factor. Each counter can also be incremented in response to any internal or external event, and checked and cleared through the Control Setpoints.

The following table lists available options.

You can preset a counter to a desired value or clear it through this dialog without affecting the counter setup. Check the Online button on the PAS toolbar before entering the setup dialog, type in the desired value into the

Counter Value box, and then click Send.

Using Periodic Timers

The PM175 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 ).

70

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

The PM175 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.

Setpoint #1 is factory preset to provide standard periodic data logs on a 15minute time basis. It is linked to the device clock and runs data logs #1 and

#2 at 15-minute boundaries of an hour.

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”.

Series PM175 Powermeters 71

Chapter 4 PAS Application Software General Meter Setup

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 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.

Using Event Flags

The PM175 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 PM175 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

72 Series PM175 Powermeters

Chapter 4 PAS Application Software General Meter Setup 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.

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 de-asserted, the following happens in your device:

1. 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.

2. 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.

3. 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.

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).

Chapter 4 PAS Application Software Configuring Summary Energy and TOU Registers

Configuring Summary Energy and TOU Registers

The PM175 provides 8 total (summary) energy and 8 concurrent tariff energy and maximum demand registers that can be linked to any internal energy source or to any external pulse source that delivers pulses through the device digital inputs.

The meter tariff structure supports 8 different tariffs using an arbitrary tariff schedule. A total of 4 types of days and 4 seasons are supported with up to eight tariff changes per day.

The meter can provide automatic daily profile recording for total and tariff energy and maximum demand registers.

By default, the billing registers in your meter and the tariff system are not operational. To activate the summary/tariff registers or to change the profile for the first billing register:

1. Link the billing registers to the respective energy sources, and then configure the options for these registers like whether the only totalization or both total and tariff registers would be used, and whether daily profiling should be enabled for the energy usage and maximum demand registers.

2. Configure the daily tariff schedule using the TOU daily profiles for all types of days and seasons.

3. Configure the season tariff schedule using the TOU calendar.

Configuring Recorders

The PM175 is provided with a 1-Megabyte onboard non-volatile memory for data, event and waveform recording.

Before using recorders, the device memory should be partitioned between log files. The device memory is fully configurable. You can define how much memory to allocate for each log file. If you want to change the factory settings, follow the guidelines in the section below.

Configuring Device Memory

The device memory can be partitioned for a total of 20 log files:

Event log

16 Data logs

2 Waveform logs

EN50160 Power Quality log

Two of the data log files – Data log #9 and #10 – are automatically configured in your meter for recording EN51060 compliance statistics data and harmonics survey data. You cannot change the file records structure, but you can change the amount of memory that will be allocated for recording data.

demands along with energy registers, then the number of sections in the file will be twice the number of the allocated TOU registers.

To configure a TOU daily profile log file:

1. Configure your TOU registers and TOU schedule in the meter before allocating memory for the profile log file (see

Setting up Total and Tariff Registers ).

2. Double click on the Data Log#16 partition with the left mouse button.

5. Select the maximum number of records you want to be recorded in the file assuming that a new record will be added once a day.

6. Click OK and send your setup to the meter or save to the database.

Configuring the Waveform Recorder

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 PM175 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:

1. Double click on a waveform log partition with the left mouse button.

2. Select a partition type for your file.

3. Select the maximum number of records you want to be recorded in the 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 per Event / 512

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.

EN50160 Evaluation and Recording

EN50160 Background

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 Techniques

EN50160 Evaluation Counters

Evaluation Counters and Evaluation Period

The PM175 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 PAS reports, using data collected since the beginning of the present evaluation interval. You can also manually clear the present contents of the counters though PAS 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 PAS provide correct weekly and yearly observation statistics regardless of the evaluation periods used for collecting data. Whenever needed, PAS 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.

You can upload and view the EN50160 compliance statistics data via PAS reports or via common PAS data logs views.

EN50160 Harmonics Survey Log

Data log file #10 is automatically configured in the PM175 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 PAS reports or via common PAS data logs views.

EN50160 Power Quality Event Log

The PM175 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 trouble-shooting 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 PAS

(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 PAS as magnitude/duration pairs on the wellknown 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 Evaluation

This section describes methods used by the PM175 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

88 Series PM175 Powermeters

Chapter 4 PAS Application Software EN50160 Evaluation and Recording

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.

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.

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 long-term flicker severity parameter Plt, which is evaluated every 2 hours.

Series PM175 Powermeters 89

Chapter 4 PAS Application Software

Method of Evaluation

EN50160 Evaluation and Recording

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

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 PM175 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.

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.

90 Series PM175 Powermeters

Chapter 4 PAS Application Software EN50160 Evaluation and Recording

Statistical Survey

The PM175 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.

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 PM175 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.

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 PM175 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.

Series PM175 Powermeters 91

Chapter 4 PAS Application Software

Indicative Values

EN50160 Evaluation and Recording

Temporary 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.

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.

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.

92 Series PM175 Powermeters

Chapter 4 PAS Application Software EN50160 Evaluation and Recording

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 limit (

±

15% Un).

Target Values

The EN50160 does not provide target limits for interharmonic voltages. The ranges of interharmonic voltages selected in the PM175 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

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 PM175 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 PM175 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).

Target Values

The voltage levels given by the EN50160 in Figure 1 of Clause 2.13 are taken from the so-called “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.

Configuring the EN50160 Recorders

Basic Device Settings

The following device settings affect the EN50160 evaluation and should be checked prior to running the EN50160 recorders.

Series PM175 Powermeters 93

Chapter 4 PAS Application Software

Reference Voltage

EN50160 Evaluation and Recording

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 .

EN50160 Logging Options

The memory allocated in your meter for the EN50160 compliance statistics and harmonics survey data is sufficient for 3-month data recording on a weekly basis. The Power Quality event log file is configured for 1000 event records. You can increase or change the size of the EN50160 data log files in your meter via the Log Memory Setup (see

Configuring Device Memory ).

EN50160 PQ Recorder Setup

The PQ recorder setup allows you to adjust the EN50160 evaluation limits

(thresholds) for the specific voltage characteristics in the case the customer requirements differ from the values provided by the EN50160, and to select the event and waveform log options for the PQ event log.

94 Series PM175 Powermeters

Chapter 4 PAS Application Software EN50160 Evaluation and Recording

To configure the PQ recorder:

1. Select Memory/Log from the Meter Setup menu, and then click on the EN50160 PQ Recorder tab.

2. 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”.

3. 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.

4. Select the waveform logging options for PQ events.

5. Download your setup to the device.

The picture above shows the default PQ recorder settings. The available options are listed in the following table.

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 sag or swell.

You can temporary disable the PQ recorder in your device. To enable or disable the PQ recorder:

1. Check or uncheck the Recorder Enabled checkbox.

2. Send your setting to the device.

Note that disabling the PQ recorder in your meter does not affect the evaluation and recording of the EN50160 statistics.

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.

Viewing Recorded Files

Viewing Options

Uploaded data can be viewed on the screen, printed, and exported to other applications.

PAS offers you different options for easy analysis of retrieved trend and fault data. Data can be displayed in primary or secondary units. You can use filtering to find out and work with a subset of events that meet the criteria you specify, or use sorting to rearrange records in the desired order. PAS can link events and the corresponding data records and waveforms together to allow you more effective analysis of recorded events.

For data log files, PAS allows you to view data trends in a graphical form, measure the delta time and magnitude between two trend points, calculate average and peak values within time intervals.

For waveform files, PAS provides phasor diagrams, symmetrical components and delta measurements, and can show you a waveform as an

RMS plot or as a spectrum chart.

For more information on viewing log files and available options, see the “PAS

Getting Started Guide”.

Viewing the EN50160 Power Quality Event Log

PQ log files are displayed in a tabular view, one event per row. PAS loads the entire database table to a window, so that you can scroll through the log to view its contents.

Selecting Voltage Units

Voltages can be displayed in primary or secondary units. To change units for your reports, click with the right mouse button on the report window, select

Options, select the desired voltage units, and then click OK.

Sorting Events

The event records are normally shown in the order based on the date and time of the event appearance. To change the sorting order, click on the Sort button on the window toolbar or click with the right mouse button on the report window and select “Sort...”, check the desired sort order, and then click OK.

Filtering Events

You can use filtering to find and work with a subset of events that meet the criteria you specify. PAS will temporary hide rows you do not want displayed.

You can use a filter along with sorting to rearrange filtered records in the desired order.

To filter events, click on the Filter button on the window toolbar, or click with the right mouse button on the report window, and then select “Filter...”.

Check the categories of events you want to display, and then click OK.

Linking to Waveforms

When displaying the PQ report, PAS establishes links between the events and waveform log records related to the events. PQ events, for which PAS finds related links, are displayed in blue. To check a list of the event links, click on the colored event ID with the left mouse button. To directly move to the related waveform record, click on the corresponding list item.

Retrieving Waveforms Online

If you programmed the PQ recorder to record waveforms on power quality events, you can upload the waveforms related to a specific event online if they have not yet been retrieved and stored to the database on your PC.

Events for which PAS did not find a corresponding waveform in the database are colored black. Click on the event ID, click on the “Retrieve Waveform” prompt, and then point to a database to which you want the waveform to be stored.

Viewing the ITI (CBEMA) Curve

Transient overvoltages (impulsive transients) and short-duration voltage variations (dips and temporary overvoltages) can be viewed as magnitude/duration pairs on the ITIC (the Information Technology Industry

Council, formerly CBEMA) curve chart. To view an ITI curve chart, click on the “ITI” button on the window toolbar.

The standard compliance statistics is reported within the selected time range on a daily, weekly or yearly basis depending on the observation periods stated in the EN50160 for voltage characteristics. If the time range includes a number of the observation intervals, each interval’s statistics is given in a separate row. For power frequency, both weekly and yearly compliance statistics are provided.

For characteristics provided with definite limits, the report shows a percentage of the observation time within which the characteristic complied with the standard, e.g. 98% of the observations in a period of one week, and the total compliance indicator.

For voltage characteristics provided with indicative values, the report gives the yearly statistical data classified by voltage magnitude and duration.

Selecting the Report Time Range

To change the time range or contents of the report, click on the report with the right mouse button, select “Options…”, select the required time range, check the voltage characteristics to be included in the report, and then click

OK.
