Displays The Master Module communicates serially with a Display Module using an Allen-Bradley communications cable. Only one Display Module can connect to a Master Module. See Figure 2.18 on page 2-19 for example.

Figure 1.1 Display Module

Communications The Powermonitor 3000 comes standard with an RS-485 communication port which uses the DF1 half duplex slave protocol. The Master Module can have additional communications installed at the factory. Refer to the appropriate communications card Installation Instruction for additional information.

• RS-232 (DF1 Half-Duplex Slave Protocol)

• RIO

• DeviceNet™

• Ethernet™

• ControlNet™

Software and System Integration

An IBM® PC, or compatible, host computer may communicate with the Powermonitor 3000 via RS-485 using:

• RSPower32

• RSLinx with DDE communications

• User-generated software

RS-485 may be used to support up to 32 devices.

r

PLC Configuration

Certain circumstances may require a number of Powermonitor 3000’s tprovide feedback while monitoring and controlling a facility. To manage

this effectively, Allen-Bradley PLC® processor communication ports can be integrated to communicate and respond to the gathered information.

Relay and KYZ output

The Powermonitor 3000 provides one high-speed SPDT relay and one KYZ solid-state relay output that can be controlled by the following sources:

• WH, VARh, VAh or Ah metering parameter

• Communications port

• Display Module

• One or more Setpoints

The solid-state KYZ output can be configured to transition every XX Wh, VARh, VAh or Ah where XX is programmable. The relay and solid-state output can be used as general-purpose remote outputs when controlled via communications or the Display Module. The relay and solid-state outputs can also function as control, alarm, or status outputs when configured to activate with one or more user-programmed setpoints. All relay and solid-state transitions (except energy pulse outputs) are recorded in the Event Log with time/date stamp. The user can configure how the relay and solid-state outputs react to a loss in communications when one or both outputs are controlled via communications. Refer to Chapter 4 and Appendix C for the relay and solid-state information and technical specifications.

Status Inputs The Powermonitor 3000 has two self-powered status inputs. These inputs sense the state of external dry contacts. Each of the status inputs has a counter associated with it that can be cleared by the user. The current state and count for each status input can be viewed on the Display Module or obtained via communications. One of the status inputs can be connected to an external utility meter output for synchronization with the utility’s

ATTENTION

!Do not control any critical loads with the relay output oKYZ output.



e

demand calculations. Status input transitions can be configured to be recorded in the event log.

Data Logging The PowerMonitor 3000 maintains three types of data logs: an Event log, a Min/Max log, and a Configurable Trend log. Every record logged is date and time stamped down to the hundredth of a second.

Event Log

The Event Log contains the 50 most recent events that occurred in the Powermonitor 3000. Some actions recorded in the event log include: configuration data change, setpoint action, force of the relay or solid-state output, a transition on one of the status inputs, power-down, power-up, and clearing of one of the energy counters. In applications where the status input changes frequently, you can disable recording of status input changes into the event log. See Table 4.10 for a complete list of items recorded in the event log.

Min/Max Log

The Min/Max Log records the minimum value, when the minimum value occurred, the maximum value, and when the maximum value occurred for 53 metering parameters. The Min/Max Log can be cleared or the results can be retrieved using the Display Module or via communications. Date and time of the last Min/Max log clear is maintained as part of the Min/Max log results. See Table 4.13 for a complete list of parameters that are recorded in the Min/Max log.

Configurable Trend Log

The configurable trend log allows the user to periodically record the value of one or more parameters over a long period of time. The log operates in one of two modes; ‘fill and hold’ mode or ‘overwrite’ mode:

When configured as ‘fill and hold’, record logging stops when the log isfull. Record logging resumes once the log is cleared by the user.

When configured as ‘overwrite’ mode, the log first fills with records andthen each new record overwrites the oldest record. Since this ‘first-in first-out’ record logging continues indefinitely, the log always contains thmost recent history of records. The user can configure the number of



parameters to be logged in each record and how often to log a record. A record can be configured to contain 1 to 16 parameters. The record interval is programmable in seconds and can range from once a second to once an hour.

Installation

Prevent Electrostatic Discharge

Mounting of Master Module

Protective Enclosure - A suitable enclosure should be used to protect the Master Module from atmospheric contaminants such as oil, moisture, dust, and corrosive vapors or other harmful airborne substances; if not, a reduced service life can be expected. Refer to Appendix C for additional mounting requirements.

The enclosure should be mounted in a position that allows the access doors to open fully. This provides easy access to the wiring of the Master Module and related components. A suggested method for spacing and wiring layout for the Master Module is shown in Appendix B. Also, see Appendix B for the drilling template.

Installation and Orientation - Normal installation and orientation of the Master Module within its protective enclosure is defined in Figure B.1 through Figure B.3 in Appendix B. This orientation ensures adequate free convection cooling of the Master Module’s internal electronic componen

Do not block ventilation slots of the Master Module. All wiring and othobstructions must be 50 mm (2.0 inches) minimum from the cooling ainlet and exit slots.

The mounting hole pattern for the Master Module is defined by the dimensional drawing in Figure B.1 in Appendix B. The Master Module cbe mounted with either four No. 8 or M4 bolts or screws with flat washeand an internal lock washer or equivalent.

ATTENTION

!Electrostatic discharge can damage integrated circuitssemiconductors. Follow these guidelines when you handle the module.

• Touch a grounded object to discharge static potent• Wear an approved wriststrap grounding device.• Do not open the module or attempt to service intern

components.• If available, use a staticsafe work station.• When not in use, keep the module in its staticshield

Mounting of Display Module

Protective Enclosure - A suitable enclosure should be used to protect the rear surfaces of the Display Module from atmospheric contaminants such as oil, moisture, dust and corrosive vapors plus other harmful airborne substances. The Display Module’s gasketed front panel interface to theprotective enclosure is rated as an IP65 degree of protection [National Electrical Manufacturer’s Association (NEMA)/Underwriters Laboratorie(UL) 508, Type 4 (Indoor)] per International Standard IEC 529.

Installation and Orientation - The Display Module can be oriented in anposition. The most typical orientation is shown in Figure B.4 in Appendix B. The Display Module is designed to fit into the protective enclosure cutout with a minimum installation depth of 50 mm (2.0 in.) behind the mounting panel as shown in Figure B.7 in Appendix B. Therecommended Display Module mounting hole pattern and dimensions adefined in Figure B.5 in Appendix B. (Use Figure B.8 in Appendix B forthe Display Module mounting template.) Ensure that the gasket providenot contaminated with foreign matter and is installed in the Display Modcorrectly. Install the Display Module into the protective enclosure’s frontpanel using four M4 nut/lockwasher assemblies as shown in Figure B.5Appendix B. Tighten the M4 nut/lockwasher assemblies to 0.9 to 1.1 Nmto 10 lb-in.)

Wiring of Master Module Terminal Blocks Wire Sizes and Screw Torques - Observe all wire lug sand screw torques. Refer to Appendix C, Technical Specifications.

Chassis Grounding - Electrically ground the Master Module using a grounding wire from the grounding terminal to earth ground. Refer to Appendix C. This protective grounding terminal shall have no other function per local codes (ground wire ≥ largest measured conductor size). All ground wires should be kept as short as possible; 30cm (12 in.) or lesuggested. Additional grounding is obtained by grounding the mountingclips on the Master Module base. Ensure a direct electrical contact betwall four clips and earth ground. For optimal EMC performance, both grouconnections (the grounding wire terminal and the mounting clips) must grounded during operation.

ATTENTION

!Failure to comply with these mounting requirements mcause damage to the Display Module or compromise tIP65 [NEMA/UL 508, Type 4 (INDOOR)] degree of protection per International Standard IEC 529.


Installation 2-3

Control PowerFigure 2.1 Bulletin 1404

The Master Module draws a nominal 15VA to facilitate retrofit applications.

The terminal block connections accept up to #12 AWG (4 mm2) wire with lugs. The Master Module must be powered from a switchable source that is overcurrent protected. Refer to Figure 2.1.

Voltage and Current Inputs

Voltage Input and Potential Transformer (PT) Selection

All Bulletin 1404 Powermonitor 3000 devices handle direct connection for line to neutral voltages of 120, 277, and 347 (line to line voltages of 208, 480, and 600V, respectively).

Use instrument accuracy PTs when the voltage levels being measured exceed the voltage input ratings. The PT accuracy rating directly affects the system accuracy. For maximum accuracy, the PT used must provide linearity across the voltage range and must introduce a minimal phase angle shift (refer to publication 1403-1.0.2 for more information on phase angle shift).

Current Inputs and Current Transformer (CT) Selection

The Powermonitor 3000 is available in a 5 Amp model. Each current input to the Powermonitor 3000 is internally CT isolated to 2kV.

Customer-provided CTs are required where input is higher than the device rating. The values for the primary and secondary CT ratings must be configured into the Powermonitor 3000 in order to properly scale the displayed readings.

The accuracy of the current input reading is dependent on the CT class. An Instrument Class 1 or better is recommended. Care should be taken that the combined load of wiring and the Powermonitor 3000 do not exceed the VA rating of the CT for maximum accuracy.

Field Service Considerations

If the Powermonitor 3000 requires servicing, please contact your nearest Allen-Bradley Sales Office. To minimize your inconvenience, the initial installation should be performed in a manner which makes removal easy.

1. A CT shorting block should be provided to allow the Powermonitor 3000 Master Module current inputs to be disconnected without open circuiting the user-supplied CT’s. The shorting block should be wiredto prevent any effect on the external protective relays.

2. All wiring should be routed to allow easy maintenance at connectito the Powermonitor 3000 terminal strips and the Powermonitor 30itself.

Firmware Upgrades Powermonitor 3000 firmware can be upgraded by downloading from a personal computer or laptop without removing the module from its installation. An RS-485/RS-232 adapter is required to connect the PC toPowermonitor 3000 native communicaiton port. Contact your local Rockwell Automation representative for information or visit the internet:

http://www.ab.com/

Factory-Installed Communication Cards

The RS-485 communications is integral to the Master Module and can be removed. Adding or changing a second communication card to a Powermonitor 3000 must be done at the factory and is not field upgradeable.

ATTENTION

!A CT circuit must not be opened with primary current present. Wiring between the CT’s should include a terminal block for shorting the CT’s. Open CT secondaries produce hazardous voltages, which can lto personal injury or death, property damage, economloss, or CT failure.


Chapter 4

General Operation

General Functionality The Display Module acts as a simple terminal that allows a user to easily view metering parameters or change configuration items. This is accomplished by using three modes of operation: Display mode, Program mode, and Edit mode.

Display mode allows any user to view any of the measured parameters that the Powermonitor 3000 provides including metering, setpoint, min/max log, event log and self-test information. The user also has the option of selecting default screens which are displayed at power-up or after 30 minutes of no key activity.

Program mode allows a privileged user to change configuration parameters. Program mode provides a basic security system where each Powermonitor 3000 is password protected and only one entity at a time can modify a Powermonitor 3000; an entity includes the Display Module, the Native Communication port or an Optional Communication Port. When a user is in Program Mode, the phase indicators (L1,L2,L3,N) flash on the Display Module.

Edit mode allows the privileged user to modify the selected parameters. When a user is in Edit mode, the parameter being modified flashes, and the phase indicators (L1,L2,L3,N) remain solid.

Key Functions The Display Module has four keys located on its front bezel: an Escape key, Up Arrow key, Down Arrow key, and Enter key. These keys maintain their same functionality for all of the Display Module’s modes. See Figure 4.1for a description of the four keys’ functionality.

Once the DM begins receiving information, it displays it on the screen athe Check Rx or Check Tx messages disappear. No operator interventirequired to clear these messages.

Scrolling When messages are too large to fit on the display, a scrolling mechanisemployed. The message scrolls on the upper or lower row (but not bothsimultaneously). The default scroll rate was chosen to give the operatoenough time to see the message but not take too much time to show thentire message. The scroll rate can be adjusted using the Advanced Configuration Menu on the Display Module. Care must be taken to seeentire message before taking any action as some of the messages are similar and differ only by a few characters.

Editing a Parameter 1. Using the Display Module keys, move into Program mode and display the parameter to be modified. Notice the flashing phase indicators on the right-hand side of the screen.

Setpoints Theory of Setpoint Operation

The Powermonitor 3000 is capable of monitoring many parameters (simultaneously), generating alarms, controlling relays, and triggering other internal actions. Setpoints are used to perform this function. The Powermonitor 3000 supports 10 simultaneous setpoints. A setpoint consists of eight parameters: setpoint number, type, evaluation condition, high limit, low limit, action delay, release delay, and action type. These parameters are described in Table 4.7.

Setpoints evaluate data based on six different conditions: over forward, over reverse, under forward, under reverse, equal, and not equal.

Over Forward Setpoint

An over forward setpoint becomes active when the magnitude of the parameter being monitored goes over the “Setpoint High Limit” in the positive direction (and stays over the limit) for a period of time greater ththe “Setpoint Action Delay” parameter. When a setpoint becomes activecauses an action identified by “Setpoint Action Type” to occur and log toccurrence in the Event log as a time-stamped event. If this action is toenergize a relay, or set an alarm bit, that action remains true until the setpoint becomes inactive. An over forward setpoint becomes inactive wthe magnitude of the parameter being monitored falls below the “SetpoLow Limit” (and stays below the limit) for a period of time greater than th“Setpoint Release Delay.” The change from active to inactive is also login the Event log as a time-stamped event.

Over Reverse Setpoint

An over reverse setpoint is the same as an over forward setpoint, except the magnitude of the parameter being monitored must go over the “SetpoinHigh Limit” in the negative direction.

When the magnitude of the parameter being monitored goes over the “Setpoint High Limit” in the negative direction (and stays over the limit) fa period of time greater than the “Setpoint Action Delay,” the setpoint becomes active. An over reverse setpoint becomes inactive when the magnitude of the parameter being monitored falls below the “Setpoint LLimit” in the negative direction (and stays below the limit) for a period otime greater than the “Setpoint Release Delay.”

Under Forward Setpoint

An under forward setpoint is the same as an over forward setpoint, except the “Setpoint High Limit” and the “Setpoint Low Limit” are reversed.

When the magnitude of the parameter being monitored falls below the “Setpoint Low Limit” in the positive direction (and stays below the limit) for a period of time greater than the “Setpoint Action Delay,” the setpoinbecomes active. An under forward setpoint becomes inactive when themagnitude of the parameter being monitored exceeds the “Setpoint HigLimit” (and stays over the limit) for a period of time greater than the “Setpoint Release Delay.”

Figure 4.12 Under Forward

Under Reverse Setpoint

An under reverse setpoint is the same as an under forward setpoint, exthe magnitude of the parameter being monitored must fall below the “Setpoint Low Limit” in the negative direction.

When the magnitude of the parameter being monitored falls below the “Setpoint Low Limit” in the negative direction (and stays below the limitfor a period of time greater than the “Setpoint Action Delay,” the setpoinbecomes active. An under forward setpoint becomes inactive when themagnitude of the parameter being monitored exceeds the “Setpoint HigLimit” in the negative direction (and stays over the limit) for a period of time greater than the “Setpoint Release Delay.”

Equal Setpoint

An equal setpoint becomes active when the parameter being monitored equals the “Setpoint High Limit” for a period of time greater than the “Setpoint Action Delay.” An equal setpoint becomes inactive when the parameter being monitored does not equal the “Setpoint High Limit” forperiod of time greater than the “Setpoint Release Delay.” The “SetpointLow Limit” is not used for equal setpoints.

The equal setpoint is most useful for non-numeric values, such as phasrotation and status input states.

Not Equal Setpoint

A not equal setpoint becomes active when the parameter being monitodoes not equal the “Setpoint High Limit” for a period of time greater thathe “Setpoint Action Delay.” An not equal setpoint becomes inactive whthe parameter being monitored equals the “Setpoint High Limit” for a period of time greater than the “Setpoint Release Delay.” The “SetpointLow Limit” is not used for not equal setpoints.

The not equal setpoint is most useful for non-numeric values, such as protation and status input states.

Relay Operation The Powermonitor 3000 has two outputs. One output is an electromechnical relay rated at 10 amps, 240Vac/250Vdc with a minimum rated life of 100,000 operations at rated load. The other is a solid-state relay rated at 80 milliamps, 240Vac - 300Vdc. Solid-state relays are typically capable of billions of operations and are the preferred choice for applications requiring frequent switching. The two relays operate independently and their functionality is dependent on the configuration of the product. Operation of these outputs is controlled by one of three mechanisms.

• Setpoint control - The outputs can be independently energized or de-energized based on the Setpoint Configuration. Refer to Setpoints on page 4-15.

• Pulsed output control - One of the outputs can be configured to provide a pulsed output based on the measured value for kWh, kVAh, or kVARh. Refer to Advanced Configuration on page 4-9 for additional information on this functionality.

• Forced operation control - The output relay state (energized or de-energized) can be forced via either the network interface or the Display Module. The forced condition is maintained until it is either removed by the user or device power is cycled. Once the forced condition is removed, the Powermonitor 3000 relays revert to normal operation.

The output can be a timed output pulse or a “KYZ” style output that occat user-configured energy consumption increments.

Figure 4.14 KYZ Pulse OutputKYZ Pulse Output

When a KYZ style output is needed:

1. Configure the desired relay for this functionality.

2. Define the switching action.

3. Select a pulse of configurable duration or a KYZ style transition output.

4. Once the appropriate relay output has been selected, configure the required control parameter (kWh forward, kWh reverse, kVARh forward, kVARh reverse, kVAh forward, or kVAh reverse).

5. Provide the pulse output increment. This configuration item determines the change in magnitude of the control parameter that must be accumulated before an output action occurs. Refer to Output Increment Determination on page 4-24.

There are two different types of KYZ interfaces: a two-wire interface and a three-wire interface. Typically, this is implemented with a Form-C output relay.

A two-wire interface utilizes only one side of the Form-C contact, while the three-wire interface uses all three connections. In both cases, an output event is characterized as a transition from the “open” state to the “closestate of the relay contact.

NOTE If desired, it is possible to use both relay outputs to provide KYZ functionality at the same time. For example, the solid state output could be used to accumulate kWh forward and the mechanical relay coube used to accumulate kWh reverse.



In a two-wire interface (KY connection), an output event occurs when the relay coil is energized. For a three-wire interface (KYZ connection), an output event occurs at the KY terminals when the relay coil is energized and at the KZ terminals when the coil is de-energized. Therefore, for an equal number of relay transitions, twice as many events occur in a three-wire interface than in a two-wire interface. See Figure 4.15 below for further clarification.

Figure 4.15 KYZ Output Events

Output Increment Determination

For both the pulsed and the KYZ outputs, the output increment must be configured. The output increment specifies the change in the selected control parameter (kWh forward, kWh reverse, kVARh forward, kVARh reverse, kVAh) that must occur in order to cause the output to transition. To calculate the output increment the following steps are required:

1. Determine the maximum value, Pmax, of the selected parameter (kWh forward, kWh reverse, kVARh forward, kVARh reverse, kVAh) that occurs in one hour.

2. Determine the number of pulses per second desired. If a two-wire KYZ output is used, this number should be between two and five. If a three-wire KYZ output or a pulsed output is used, this number should be between two and ten.

3. Convert the selected parameter to the appropriate units per second by dividing Pmax by 3,600 (the number of seconds in one hour).

4. Compute the output increment by dividing the above result by the desired number of pulses per second and rounding the answer to the nearest integer. For a two-wire KYZ interface, multiply the number of pulses per second by two before dividing. This is necessary because the relay must transition twice to create a pulse in this configuration.

The following example illustrates the process for a system in which the maximum forward power to be metered is 1,200 kWh and the desired output pulse rate for a three-wire “KYZ” output is four pulses per secon

1. Pmax = 1,200 kWh

2. Four pulses per second desired

3. Divide Pmax by 3,600 to compute Wh per second Pmax = 333.33 Wh per second

4. Output increment = 333.33 Wh per second divided by four pulsessecondOutput increment = 83.3333 Wh per pulseRound output increment to nearest integer → Output increment = 83 Wh per pulse

(The appropriate number for a two-wire KYZ interface would be 42 Wh ppulse.)

Data Logging The Powermonitor 3000 maintains 3 types of data logs:

• Event log

• Min/Max log

• Configurable Trend log

Every record logged is date and time stamped down to the hundredth osecond. Information collected by the logs is stored in non-volatile FLASmemory indefinitely in the event of a loss of control power.

Event Log

The Event log consists of the 50 most recent events that occurred in thPowermonitor 3000. Some actions which are recorded in the event log include: configuration data change, setpoint action, force of the relay orsolid-state output, a transition on one of the status inputs, power-down,power-up, and clearing of one of the energy counters. In applications wthe status input changes frequently, the user can disable recording of sinput changes into the event log. Table 4.10 shows a complete list of itethat can be recorded in the event log.

Whenever a setpoint event occurs, the setpoint setup information is also logged. This information is viewed via the Display Module by pressing the Enter key (↵) when the setpoint event is displayed. This information can also be retrieved via the communication port.

Configurable Trend Log

The configurable trend log allows the user to periodically record the value of one or more parameters over a long period of time. Configuration of the trend log is accomplished through system communications and software, it is not a Display Module feature. The log operates in one of two modes; and hold’ mode or ‘overwrite’ mode.

• When configured as ‘fill and hold’, record logging stops when the lis full. Record logging resumes once the log is cleared by the use

• When configured as ‘overwrite’ mode, the log first fills with recordand then each new record overwrites the oldest record. Since this‘first in first out’ record logging continues indefinitely, the log alwaycontains the most recent history of records.

The user can configure the number of parameters to be logged in eachrecord and how often to log a record. A record can be configured to con1 to 16 parameters. The record interval is programmable in seconds anrange from once a second to once an hour.

The maximum number of records that can be logged depends on the nuof parameters in each record. The number of records that can be loggecalculated from equation #1. If you know the desired record depth, youdetermine the maximum number of parameters using equation #2.

All results should be truncated to an integer value.

Figure 4.16 Equation #1 Log DepthWhere:

D = the Depth of the trend log in records

F = the trend log Fill type; range 0 to 1 (0=‘fill and hold’ mode, and 1=’overwrite’ mode)

Here are a few examples using the above formulas:

Example #1

Question: I want to log kW every 15 minutes. What is the maximum number of records I can log, and what span of time will it cover?

Answer: We’ll use equation #1 above since we are looking for the log depth. Here are the values to insert into the equation:

Figure 4.18 Example #1F = 0 (‘fill and hold’ mode allows the greatest number of records to be logged)P = 1 (1 parameter per record)

Therefore, using the equation in Figure 4.18:D = 45,866.8 (truncating to an integer number, we get 45,866 records)

Since a record is logged every 15 minutes, this particular log configuratcan hold 15.8 months of kW data.

Example #2

Question: I would like to setup the Powermonitor 3000 to record severaparameters every 10 seconds indefinitely. Within a week following the eof each month, I will fetch the data from the Powermonitor 3000, save iand create a trend graph on my PC. How many parameters can I log inrecord?

Answer: First we need to determine the required record depth, based olog interval and total duration

31+7 days = 38days * 24 hours per day * 60 seconds per minute = 54,7seconds; if logged every 10 seconds, the log would require 5,472 recor

Now that we have the log depth, equation #2 can be used to determinemaximum number of parameters that can be recorded per record.

Figure 4.19 Example #2F = 1 (‘overwrite’ mode allows the log to be read without loosing any daD = 5,472 records required at 1 record every 10 seconds to collect 38 dworth of data

Therefore, using the equation in Figure 4.19:

P = 16.4 (16 parameters)

The trend log can record the values for 16 parameters every 10 second38 day sliding window.

Glossary

ampere A unit of electrical current or rate of flow of electrons. One volt across one ohm of resistance causes a current flow of one ampere. A flow of one coulomb per second equals one amp.

apparent powerThe product of voltage magnitude and current magnitude in a circuit. Units are VA or some multiple thereof.

balanced loadAn alternating, current power system consisting of more than two current carrying conductors in which these current carrying conductors all carry the same current.

billing demand The demand level that a utility uses to calculate the demand charges on the current month’s bill. Various methods may be used to determine the valsuch as minimum demand, peak demand or a ratchet clause. It can be on Watt Demand, VA Demand, VAR Demand or some combination of these. A rate at which a transmission occurs, where one baud equals oper second.

burdenThe electrical load placed on source of VA or the load an instrument or meter places on a current or potential transformer. All current and potentransformers have a rated burden which should not be exceeded or elstransformer transformation accuracy deteriorates.

capacitorA device consisting essentially of two conducting surfaces separated binsulating material or dielectric. A capacitor stores electrical energy, blothe flow of direct current, and permits the flow of alternating current to adegree dependent upon the capacitance and frequency. They may alsoused to adjust the power factor in a system.

connected loadThe total load which a customer can impose on the electrical system if everything was connected at one time. Connected loads can be measuhorsepower, watts or volt-amperes. Some rate schedules establish a minimum demand charge by imposing a fee per unit of connected load.

current transformer (CT)A transformer, intended for measuring or control purposes, designed tohave its primary winding connected in series with a conductor carrying current to be measured or controlled. CT’s step down high currents to lovalues which can be used by measuring instruments.

current transformer ratio The ratio of primary amperes divided by secondary amperes.


Glossary 2

demand hoursThe equivalent number of hours in a month during which the peak demand is fully utilized. In other words, if energy consumption for the current month is X kwhr and the peak demand is Y Kw, then the demand hours is equal to X/Y hours. The higher the number of demand hours, the better the demand leveling situation, and the more effectively demand is being used.

demand intervalDemand charges are based on peak demand over a utility specified time interval, not on the instantaneous demand (or connected load) at any given moment. Typical demand intervals are 15, 20, and 30 minutes.

frequencyThe number of recurrences of a periodic phenomenon in a unit of time. In electrical terms, frequency is specified as so many Hertz (Hz) where one Hz equals one cycle per second.

horsepower (hp)A unit of power, or the capacity of a mechanism to do work. It is equivalent to raising 33,000 pounds one foot in one minute. One horsepower equals 746 watts.

impedanceThe total opposition (i.e., resistance and reactance) a circuit offers to the flow of alternating current at a given frequency. It is measured in ohms.

induction motorAn alternating current motor in which the primary winding (usually the stator) is connected to the power source and induces a current into a secondary (usually the rotor).

inductorA device consisting of one or more windings with or without a magnetic core. Motors are largely inductive.

initiator pulsesElectrical impulses generated by pulse-initiator mechanisms installed in utility revenue meters. Each pulse indicates the consumption of a specific number of watts. These pulses can be used to measure energy consumption and demand.

lagging currentThe current flowing in an AC circuit which is mostly inductive. If a circuit contains only inductance the current lags the applied voltage by 90 degrees. Lagging current means lagging power.

leading currentThe current flowing in a circuit which is mostly capacitive. If a circuit contains only capacitance the current leads the applied voltage by 90 degrees. Leading current means leading power factor.


Glossary 3

hase nt

e in

loadAny device or circuit consuming power in an electrical system.

load sheddingThe removal of load from the line to limit load and control demand level.

load restoringThe energization of loads that were previously removed from the line to limit load and control demand level.

neutralThe conductor chosen as the return path for the current from the load to the source. It is also a voltage reference point in a power system.

ohmThe unit of electrical resistance. One ohm is the value of resistance through which a potential difference of one volt will maintain a current flow of one ampere.

peak demandThe highest average load over a utility specified time interval during a billing period. If there is no ratchet clause in the rate schedule, then the peak demand is also the billing demand.

polyphaseHaving or utilizing several phases. A polyphase power circuit has several (typically three) phases of alternating current with a fixed phase angle between phases.

potential transformer (PT)An transformer with the primary winding connected in parallel with the circuit whose voltage is to be measured or controlled. PT’s are normallyused to step down high-voltage potentials to lower levels acceptable tomeasuring instruments. Also known as voltage transformer (VT).

potential transformer ratioThe ratio of primary voltage divided by secondary voltage.

power factorThe ratio of real power in watts of an alternating current circuit to the apparent power in volt-amperes. Also expressed as the cosine of the pangle between the fundamental voltage applied to a load and the currepassing through it.

power factor correctionSteps taken to raise the power factor by closely aligning the current to bphase with the applied voltage. Most frequently this consists of added capacitance to increase the lagging power factor of inductive circuits.


Glossary 4

power factor penaltyThe charge utilities impose for operating at power factor below some rate schedule-specified level. This level ranges from a lagging power factor of 0.80 to unity. There are innumerable ways by which utilities calculate power factor penalties.

ratchet clauseA rate schedule clause which states that billing demand may be based on current month peak demand or on historical peak demand, depending on relative magnitude. Usually the historical period is the past eleven months, although it can be for the life of the contract. Billing demand is either the current month peak demand or some percentage (75 percent is typical) of the highest historical peak demand, depending on which is largest. It is designed to compensate the electric utility for maintaining equipment not fully utilized.

reactanceThe opposition to the flow of alternating current. Capacitive reactance is the opposition offered by capacitors and inductive reactance is the opposition offered by an inductive load. Both reactances are measured in ohms.

real powerThe component of apparent power that represents real work in an alternating current circuit. It is expressed in watts and is equal to the apparent power times the power factor.

resistanceThe property of a substance which impedes current flow and results in the dissipation of power in the form of heat. The unit of resistance is the ohm. One ohm is the resistance through which a difference of potential of one volt will produce a current of one ampere.

revenue meterA meter used by a utility to generate billing information. Many types of meters fall in this category depending on the rate structure.

root mean square (RMS)The effective value of alternating current or voltage. The RMS values of voltage and current can be used for the accurate computation of power in watts. The RMS value is the same value as if continuous direct current were applied to a pure resistance.

sliding demand intervalA method of calculating average demand by averaging the average demand over several successive short time intervals, advancing one short time interval each time. Updating average demand at short time intervals gives the utility a much better measure of true demand and makes it difficult for the customer to obscure high short-term loads.


Glossary 5

unbalanced loadA situation existing in a three-phase alternating current system using more than two current carrying conductors where the current is not due to uneven loading of the phases.

volt-ampere (VA)The unit of apparent power. It equals volts times amperes regardless of power factor.

volt-ampere demandWhere peak average demand is measured in volt-amperes rather than watts. The average VA during a predefined interval. The highest average, i.e. Peak VA demand, is sometimes used for billing.

voltage (V)The force which causes current to flow through a conductor. One volt equals the force required to produce a current flow of one ampere through a resistance of one ohm.

watt (W)A measure of real power. The unit of electrical power required to do work at the rate of one joule per second. It is the power expended when one ampere of direct current flows through a resistance of one ohm. Equal to apparent power VA times the power factor.

watt demandPower during a predetermined interval. The highest average, i.e. Peak demand is commonly used for billing.

watt hour (Whr)The number of watts used in one hour. Since the power usage varies, it is necessary to integrate this parameter over time. Power flow can be either forward or reverse.

wattmeterAn instrument for measuring the real power in an electric circuit. Its scale is usually graduated in watts, kilowatts, or megawatts.

volt ampere reactive hours (VARH)The number of VARs used in one hour. Since the value of this parameter varies, it is necessary to integrate it over time. VARs can be either forward or reverse.
