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:

 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 second method is preferable.

 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:

PULSE MODE KYZ MODE

PULSE MODE

In pulse mode, either leading, or trailing edge of the input pulse is recognized as an event. In KYZ mode, both leading and trailing edges of the input pulse are recognized as separate events.

Pulse Polarity

NORMAL (N.O.), INVERTING (N.C.)

NORMAL

For the normal polarity, the open to closed transition is considered a pulse. For the inverting polarity, the closed to open transition is considered a pulse. It has no meaning in KYZ mode where both transitions are used.

Debounce Time

1-100 ms

10 ms

The amount of time while the state of the digital input should not change to be recognized as a new state. Too low debounce time could produce multiple events on the input change.

The debounce time is applied the same for all digital inputs. If you change the debounce time for a digital input, the same debounce time is automatically assigned to the others.

Configuring Relay Outputs

The PM135 can be provided with two to four (depend on DI/O module type) optional relay outputs. Each relay can be operated either locally from the alarm/control setpoints in response to an event or by a remote command sent through communications. It can also be linked to an internal pulse source to produce energy pulses.

Operation mode

UNLATCHED LATCHED PULSE KYZ pulse

UNLATCHED

Unlatched mode: the relay goes into its active state when the control setpoint is in active (operated) state, and returns into its non-active state when the setpoint is released. Latched mode: the relay goes into its active state when the control setpoint goes into active state and remains in the active state until it is returned into its non-active state by a remote command. Pulse mode (normal pulse): the relay goes into its active state for the specified time, goes into non-active state for the specified time and remains in the non-active state. KYZ mode (transition pulse): the relay generates transition pulses. The relay changes its output state upon each command and remains in this state until the next command.

Polarity

NORMAL (N.O.) INVERTING (N.C.)

NORMAL

Normal polarity: the relay is normally deenergized in its non-active state and is energized in its active (operated) state. Inverting polarity: the relay is normally energized in its non-active state and is deenergized in its active (operated) state. It is called failsafe relay operation.

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 energy accumulator

and the pulse rate for your output.

3. Send your new setup to the meter.

Configuring Analog Outputs

The meter can be ordered with two optional analog outputs with options for 0-1mA, ±1mA, 0-20mA and 4-20mA current outputs.

Using PAS

Output parameter

See Appendix B

Selects the measured parameter to be transmitted through the analog output channel.

Zero scale

Defines the low engineering scale (in primary units) for the analog output corresponding to a lowest (zero) output current (0 or 4 mA)

Full scale

Defines the high engineering scale (in primary units) for the analog output corresponding to a highest output current (1 or 20 mA)

When you select an output parameter for the analog output channel, the default engineering scales are set automatically. They correspond to the maximum available scales. If the parameter actually covers a lower range, you can change the scales to provide a better resolution on an analog output.

Scaling Non-Directional Analog Outputs

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.

Chapter 5 Configuring the PM135 General Meter Setup

88 PM135 Powermeter Series

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). The negative power factor is scaled as -1.000 minus the measured value, and non-negative power factor is scaled as +1.000 minus the 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 ±1mA 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.

For an unsigned output value, you can change both zero and full engineering scales.

For a signed (directional) value, you should only provide 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 meter does not allow access to the low scale setting if the parameter is directional. Whenever the sign of the output parameter is changed to negative, the meter automatically uses the full engineering scale setting for +1 mA with a negative sign.

Scaling Analog Outputs for 0-2 mA and ±2 mA

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 you set for the 1 mA or ±1mA.

The output scales for 0-1 mA and ±1 mA analog outputs are programmed for 0 mA and +1 mA regardless of the required output current range.

To use the entire output range of 2 mA or ±2 mA, set the analog output scales as follows:

 0-2 mA: set the 1 mA scale to ½ of the required full scale output

for uni-directional 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 ½ 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.

Configuring Counters

The PM135 has four six-digit general counters that can count pulses delivered through the device digital inputs with a programmable scale factor. Each counter can also be incremented in response to any internal or external event, checked and cleared through the Control Setpoints.

Using PAS

Select General Setup from the Meter Setup menu, and then click on the Pulse/Event Counters tab.

Configuring Alarm/Control Setpoints

The PM135 has an embedded logical controller that can perform 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 one

trigger argument. Whenever an expression is evaluated as “true”, the

setpoint performs a programmable action that can send a command to the output relay, or increment a counter.

The logical controller provides very fast response to events. The scan time for all setpoints is 1 cycle time (16.6 ms at 60Hz and 20 ms at 50/400 Hz).

Using Numeric Triggers

For numeric (analog) triggers, you can 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 value as the Operate Limit.

Using Binary Triggers

Binary (digital) triggers like digital inputs and relays are tested for ON/CLOSED or OFF/OPEN status.

In the PM135, the binary events are level-sensitive events. An event is asserted all the time while the corresponding condition exists.

Delaying Setpoint Operations

Two optional delays can be added to each setpoint to extend monitoring triggers for a longer time before reaching a decision on whether the expected event occurred or not. When a delay is specified, the logical controller changes the setpoint status only if all conditions are asserted for a period of at least as long as the delay time.

Chapter 5 Configuring the PM135 General Meter Setup

92 PM135 Powermeter Series

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 meter:

 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 that can be inspected through communications and via the display (see Status Display in Chapter 3). The register holds the last setpoint alarm status until it is explicitly cleared through communications or via the display.

 A programmable action is performed 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 that are shared for each target relay between all setpoints using an OR scheme.

A relay output is operated when one of the setpoints linked to the relay is activated and remains operated until all of these setpoints are released (except for latched relays that require a separate release command to be deactivated).

Using Time Counters

Any of the general counters can be used to count the setpoint operation time. If you select the TIME CNT n action for a setpoint, the target counter measures the time while the setpoint is in the operated state. The counter resolution is 0.1 hour. See Status Display in Chapter 3 on how to examine the counters via the front display.

PM135 Powermeter Series 99

5.4 Configuring Billing/TOU

The TOU battery-backed clock unit is highly recommended in case of using time-scheduled tariff rates, otherwise a long power outage may cause the meter clock to lose time so your tariff counters would not comply with the calendar schedule.

Billing Energy Registers

The PM135E/EH has 4 fully programmable billing energy registers that can be linked to any internal energy source or to an external pulse source that delivers pulses through the meter digital inputs.

Any energy register can provide either a single-tariff energy accumulation or be individually linked to the TOU system providing both total and multitariff energy billing.

Tariff Rates

The meter tariff structure supports 8 different tariff rates 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.

Maximum Demand Registers

Any of billing energy registers can be individually linked to the maximum demand register providing the same demand tariff structure as you selected for energy registers.

Recording Billing Data and Load Profiling

The PM135E/EH can provide automatic recording of the daily energy and maximum demand profile to a data log file. Maximum demand profiling can be individually configured for every register.

See Factory Preset Data Log Files in Chapter 5 and Billing Profile Log File in Appendix E for more information on the file layout and contents.

To configure the billing registers and the tariff system in your meter:

1. Link the billing registers to the

respective energy sources.

2. Configure the options for the

registers to 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.

3. Configure the daily tariff schedule

using the TOU daily profiles for all types of days and seasons.

4. Configure the season tariff schedule

using the TOU calendar.

Configuring Billing/Tariff Registers
