Product Description

Chapter Objectives

After completing this chapter, you should be able to identify the product features and system applications.

Introduction

The Bulletin 1403, Powermonitor II, is uniquely designed and developed to meet the needs of producers and consumers of electric power. The Powermonitor II is a microprocessor based monitoring and control device well suited for a variety of applications. Use of voltage, current, status inputs, and relay connections allows the Powermonitor II to provide monitoring and control information. This data is useful in substation and distribution centers, electrical control panels, and many utility, commercial, and industrial applications including motor control centers. The Powermonitor II is a sophisticated modern alternative to traditional electro-mechanical metering devices. One Powermonitor II can replace many individual transducers and meters within a single package. The Powermonitor II is operator friendly and provides the user with easy to understand, accurate information in a compact economical package.

General Description

The Bulletin 1403 Display Module, an optional input/ output device, can be used to set up and configure the Bulletin 1403 Master Module for operation. This is accomplished through the Display Module’s front panel which includes four tactile operator buttons and a liquid crystal display. All communications between the Display Module and Master Module are conducted over a serial fiber optic link. (The Display Module is easily mounted into a typical instrument panel analog meter cutout.)

A second optional feature allows for remote communications through the use of a Smart Communications Card co-located with the Master Module. Both the Display Module and the Smart Communications Card are microprocessor based providing better resolution, accuracy, and speed to the Bulletin 1403 Master Module. The bulletin 1403 Powermonitor II and the Communication Cards are Year 2000 compliant.

Performance Features

The Powermonitor II performance features include:

• Voltage, current, power measurements and display• 28 ms to 90 ms selectable update rates for

metering results (1403-MM only)• 90 ms fixed update rate (1403-LM only)• Communications• Software and system integration• PLC-5 compatibility• SLC-500 compatibility• Output control via control relays or PLC• Demo mode for training• Input monitoring via status inputs• Time stamped data logging of system

measurements and events• Harmonic Analysis (1403-MM only)• Simultaneous multi-channel oscillograph

recordings (1403-MM only)

Device Configuration

The Powermonitor II comes from the factory with default settings but can be configured for local site-specific requirements. This is accomplished using the Display Module or one of the Communications Cards which allow operation and configuration parameters to be sent to the Master Module.

In conjunction with the Communications Cards, a personal computer running RSPower™ or RSEnergy™ software can be sent to the Master Module.

Quick Start - Minimum Device Configuration

At a minimum, the following steps MUST be followed for proper operation of your Powermonitor II. Any other device configuration options are only required for operation of additional functions of the Powermonitor II.

1. Configure the PT and CT ratios to match your system. Remember, for systems with greater than 120 volts applied to the voltage inputs, the PT secondary must be configured to greater than 137 volts to switch to high voltage mode. For example: a 600 VL-L (347 VL-N) direct-connect system is configured with a PT ratio of 347:347.

2. Configure the Voltage Mode to match your system wiring. Use the wiring diagrams in Chapter 2, Figure 2.2 through Figure 2.13 to select the appropriate mode.

Measurements

The Powermonitor II provides numerous display measurements and programming characteristics.

Note: Update rates and accuracy are listed in Appendix C, Technical Specifications

Displays

The Powermonitor II Master Module communicates to the Display Module over a fiber optic serial communications link. Up to three Display Modules can connect to one Master Module.

Communications

Both versions of the Powermonitor II can use the 1403-NSC Smart Communications Card for communications via Allen-Bradley Remote I/O, RS-232 or RS-485, the 1403-NENET card for communications via Ethernet, or the 1403-NDNET card for communications via DeviceNet. Refer to Publication 1403-5.1 Smart Communications Card Instruction Sheet, Publication 1403-5.3 Ethernet Communications Card Instruction Sheet, or Publication 1403-5.4 DeviceNet Communication Card Instruction Sheet for additional information.

Software and System Integration

An IBM PC, or compatible, host computer may communicate with the Powermonitor II via RS-232C, RS-485, R I/O, DeviceNet, or Ethernet using:

• RSPower• RSView• RSEnergy• RSLinx• User generated software (using open protocol -

see Publication 1403-5.1, Smart Communications Card Instruction Sheet)

• User generated software (using open protocol - see Publication 1403-5.3, Ethernet Communications Card Instruction Sheet)

RS-232C/RS-485 may be used to support up to 124 Powermonitor IIs per sub net, 250 per network.

PLC Configuration

Certain circumstances may require a number of Powermonitor IIs to provide 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.

Setup/Monitoring Software

The Windows-based RSPower and RSEnergy software packages are currently available from Rockwell Software for configuring, monitoring, and control of the Powermonitor II units. This software package is designed to be integrated with RSView or function as a stand alone package. It is capable of graphically displaying a system and its components and providing real time data and graphics on the same screen. Real time data can be displayed in digital or analog presentation using preconfigured gauges. Spectral analysis, oscillograph recordings, logging, and trending are also easily configured. When either software is used in conjunction with RSView, data can be entered into the tag database editor. Configuration and real time data can be downloaded and retrieved from any Bulletin 1400/1403 Powermonitor on the system.

Note: Spectral analysis and oscillograph recordings are only available through the 1403-MM only.

Control Relays

The Powermonitor II provides two high speed SPDT control relays which may function as:

• Alarm relays• Setpoint relays• Remote control relays operated by command via

the communications port or Display Module.• Relays controlled by user-defined conditions• kWH or kVARH pulse outputs• Relay operations may be logged to a PC printer

output using a software package.

Status Inputs

The Powermonitor II has four self-powered status inputs. These inputs can be used to sense and control the state of an external contact. Each of the status inputs has a counter associated with it. The status of these inputs can be viewed from the Powermonitor II Display Module. They may also be viewed and logged from RSPower or RSEnergy software or user generated software.

1-4 Product Description

1403-IN001A-US-P

Data Logging

The Powermonitor II provides three data logs: the Event log, the Min/Max log, and the Snapshot log. Each record of the three logs is date and time stamped to the nearest hundredth of a second.

Event Log

The Event log consists of the 100 most recent events that occurred in the Powermonitor II. Such events consist of power up/power down, setpoint activation, new configuration data, etc.

Min/Max Log

The Min/Max log records the minimum and maximum values for 84 parameters for the 1403-MM and 63 parameters for the 1403-LM. These items consist of voltage, current, power, total harmonic distortion, etc. This log can be disabled to increase real time metering update rate performance.

Snapshot Log

The Snapshot log consists of 50 records. Each record consists of 46 parameters. These parameters include voltage, current, power, power factor, etc. This log can be updated on a periodic basis set by the configuration data, and/or it can be updated asynchronously as a result of a setpoint action.

Oscillography (1403-MM only)

The Powermonitor II provides two types of oscillography:

• Simultaneous 7-channel 2-cycle(1) oscillograph recording

• User configurable simultaneous 2-channel 12-

cycle(2) oscillograph recording with up to 8 cycles of pretrigger data.

Both types of oscillography can be triggered manually or as the result of a setpoint. All channels are continuously sampled at a 10.8 kHz sample rate.

Operational Characteristics

1403-MM

The Powermonitor II MM module has selectable accuracy (+/- 0.05% nominal) and update rates (28 to 90 ms) by changing various configuration parameters. If update rates are critical, then a user can select a modest filtering mode or disable unnecessary features. However, if maximum accuracy is a necessity for a specific application, then the user can select an additional filtering mode. The Powermonitor II allows a user to trade update speed for accuracy.

1403-LM

The Powermonitor II LM module has a fixed accuracy (+/- 0.1 nominal) and a fixed update rate of 90 ms.

(1) 2-cycle is specified at 50 Hz (2.4 cycles at 60 Hz). Therefore, more data will be available at frequencies greater than 50 Hz, while less will be available at frequencies less than 50 Hz.

(2) 12 cycles is specified at 50 Hz (14.4 cycles at 60 Hz). Therefore, more data will be available at frequencies greater than 50 Hz, while less will be available at frequencies less than 50 Hz.

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.

The enclosure should be mounted in a position that allows the access doors to open fully. This will provide 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 drilling template.

Installation and Orientation Normal installation and orientation of the Master Module within its protective enclosure is defined in Figure B.1, Appendix B. This orientation will ensure adequate

free convection cooling of the Master Module’s internal electronic components.

Important: Do not block ventilation holes of the Master Module. All wiring and other obstructions

The mounting hole pattern for the Master Module is defined by the dimensional drawing in Figure B.2, Appendix B. The Master Module can be mounted with either four No. 10 or M5 bolts or screws with flat washers and an internal lock washer or equivalent.

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 the protective enclosure is rated as an IP65 degree of protection [National Electrical Manufacturer’s Association (NEMA)/Underwriters Laboratories (UL) 508, Type 4X (Indoor)] per International Standard IEC 529.

Installation and Orientation The Display Module can be oriented in any position. The most typical orientation is shown in Figure B.1, Appendix B. The Display Module is designed to fit into the protective enclosure cutout with a minimum installation depth of 50.8 mm (2.0 in.) behind the mounting panel as shown in Figure B.2, Appendix B. The recommended Display Module mounting hole pattern and dimensions are defined in Figure B.3, Appendix B. Ensure that the gasket provided is not contaminated with foreign matter and is installed in the Display Module correctly. Install the Display Module into the protective enclosure’s front panel using four M4 nut/lockwasher assemblies as shown in Figure B.4, Appendix B. Tighten the M4 nut/lockwasher assemblies to 0.9 to 1.1 Nm (8 to 10 lb-in.)

Note: Eight flat washers are provided for retrofit applications with larger hole sizes.

!ATTENTION: Electrostatic discharge can damage integrated circuits or semiconductors if you touch backplane connector pins. Follow these guidelines when you handle the module.

• Touch a grounded object to discharge static potential.

• Wear an approved wrist-strap grounding device.

• Do not touch the backplane connector or connector pins.

• Do not touch circuit components inside the module.

• If available, use a static-safe work station.• When not in use, keep the module in its

static-shield box.

2-2 Installation

1403-IN001A-US-P

Wiring of Master Module

Terminal Blocks Wire Sizes and Screw Torques Observe all wire lug sizes and screw torques. Refer to Appendix C, Specifications.

Chassis Grounding Electrically bond the Master Module to the wiring installation via a bonding terminal. Refer to Technical Specifications, Appendix C. This protective earthing terminal shall have no other function per local codes (ground bond ≥ largest measured conductor size). All ground wires should be kept as short as possible; 30cm (12 in.) or less is suggested.

Control Power

The power required by the Master Module is less than 25VA to facilitate retrofit applications, but the terminal block connections accept up to #12 AWG

(4 mm2) wire with lugs. The Master Module can be powered directly from a local branch circuit. It should be fused per local code.

1403-IN001A-US-P

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.

Note: Remember, for systes with greater than 120 volts applied to the voltage inputs, the PT secondary must be configured to greater than 137 volts to switch to high voltage mode. Example: A 600 VL-L (347 VL-N) direct-connect system would be configured with a PT ratio of 347:347.

Current Inputs and Current Transformer (CT) Selection

The Powermonitor II is available in two models: a 5 Amp or 1 Amp model. Each current input to the Powermonitor II is internally CT isolated to 5kV. Each current input may be connected directly into the power line as long as the currents do not exceed the 5 Amp or 1 Amp ratings.

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 II 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 II match closely to the VA rating of the CT for maximum accuracy.

!ATTENTION: A CT secondary circuit must not be opened with primary current applied. Wiring between the CTs and the Powermonitor II should include a terminal block for shorting the CT secondary circuit. Shorting the secondary with primary current present will allow other connections to be removed if needed. An open CT secondary with primary current applied will produce a hazardous voltage, which can lead to personal injury, death, property damage or economic loss.

LED Indicators

The Powermonitor II is equipped with two light emitting diodes (LED) labeled “Power” and “OK.” The Power LED illuminates when sufficient power is applied to the device. The OK LED flashes when the device is initially powered; this indicates that the device is running internal self tests. After the OK LED flashes and the internal self tests pass, the OK LED remains illuminated indicating that the device is in good operating condition. If the OK LED does not remain illuminated, this indicates that an internal self-test did not pass and service is needed (refer to Chapter 3, Field Service Considerations ).

Wiring of Display Module

Note: All ground wires should be kept as short as possible; 30cm (12 in.) or less is suggested.

Power

The Display Module can be operated on either AC or DC power. Two models have been developed to operate on various AC/DC voltage ranges as defined in Table 2.4. A single, three-position connector is provided for all power connections to the Display Module.

Terminal Block Wire Sizes and Screw Torque Values

All terminal block wire sizes and terminal block screw torque values are shown in Appendix C, Technical Specifications .

Fiber Optics

The Powermonitor II communications architecture consists of a fiber optic ring between the Bulletin 1403 Master Module and up to three Display Modules. The black transmitter component (TX) of a unit must be connected to the blue receiver (RX)

component of the next unit and repeated for each additional module until the ring is completed. Figure 2.17 shows a typical layout of the fiber optic cabling between one Master Module and three Display Modules. Fiber optic cable assembly specifications are given in Table 2.5 on page 2-18.

Important: Always maintain furnished rubber plugs in the transmitter and receiver when cable end connectors are not in place. This helps prevent dirt from contaminating the transmitter or receiver.

In the United States, transportation of depleted lithium batteries for disposal is controlled by the Code of Federal Regulations, Title 49. Depleted lithium batteries are defined by the extent that the open circuit voltage is less than the lower of:• 2.0 volts or• Two-thirds of the voltage of a fully charged

battery

Check the Code of Federal Regulations, Title 49 or local regulations regarding the current methods and procedures for the disposal of lithium batteries.

Calibration

The calibration interval for the Powermonitor II depends on the user’s accuracy requirements. To meet general operating requirements, regular recalibration is not necessary.

Contact your nearest Allen-Bradley Sales Office for calibration or service information.

Cleaning Instructions

1. Turn off all electrical power supplied to the Master Module and Display Module.

2. Clean the Master Module with a dry, anti-static, lint-free cloth. Remove all dust and any obstructions from the cooling air vents on the upper, lower, and ends of the module. Ensure that the nameplate is clean and in good condition.

3. Clean the Display Module with a dry, anti-static, lint-free cloth. Remove all dust and any foreign material(s) from the exterior of the module. Ensure that the graphic front panel overlay and back nameplate are clean and in good condition.

Field Service Considerations

If the Powermonitor II 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 II Master Module current inputs to be disconnected without open circuiting the user supplied CTs. The shorting block should be wired to prevent any effect on the external protective relays.

2. All wiring should be routed to allow easy maintenance at connections to the Powermonitor II terminal strips, the Powermonitor II rear cover, and the Powermonitor II itself.

!ATTENTION: The battery is held under pressure within its holder and may be forcefully ejected upon extraction.

!ATTENTION: • Disconnect and lock out all power sources

and short all current transformer secondaries before servicing. Failure to comply with these precautions can lead to personal injury or death, property damage or economic loss.

• Please follow appropriate Electrostatic Sensitive Discharge (ESD) procedures during cleaning.

!ATTENTION: A CT circuit must not be opened with primary current present. Wiring between the CTs should include a terminal block for shorting the CTs. Open CT secondaries will produce hazardous voltages, which can lead to personal injury or death, property damage, economic loss, or CT failure.

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 II provides including metering information, harmonic analysis (1403-MM only), and logging information. The user also has the option of selecting default screens which are displayed at power-up or after 30 minutes of non-activity.

Program mode allows a privileged user to issue commands or select a parameter to modify. Program mode provides a basic security system where each

Powermonitor II is password protected, and only one entity can modify a Powermonitor II; an entity includes one of the three possible Display Modules or the Smart Communication Card. When a user is in Program Mode, a flashing “P” is displayed at the bottom right-hand corner of 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 flashing “P” remains 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 making the Display Module easy to use. The functionality of the four keys is shown in Figure 4.1.

Setpoints

Theory of Setpoint Operation

The Powermonitor II 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 II supports 20 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 4.8.

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 than the “Setpoint Action Delay” parameter. When a setpoint becomes active, it causes an action identified by “Setpoint Action Type” to occur and log this occurrence in the Event log as a time-stamped event. If this action is to energize a relay, or set an alarm bit, that action remains true until the setpoint becomes inactive. An over forward setpoint becomes inactive when the magnitude of the parameter being monitored falls below the “Setpoint Low Limit” (and stays below the limit) for a period of time greater than the “Setpoint Release Delay.” The change from active to inactive is also logged in the Event log as a time-stamped event.

1403-IN001A-US-P

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 “Setpoint High 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) for a

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 Low Limit” in the negative direction (and stays below the limit) for a period of time greater than the “Setpoint Release Delay.”

1403-IN001A-US-P

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 setpoint becomes active. An under forward setpoint becomes inactive when the magnitude of the parameter being monitored exceeds the “Setpoint High Limit” (and stays over the limit) for a period of time greater than the “Setpoint Release Delay.”

Under Reverse Setpoint

An under reverse setpoint is the same as an under forward setpoint, except the 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 limit) for

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

Figure 4.7 Under Reverse

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” for a period of time greater than the “Setpoint Release Delay.” The “Setpoint Low Limit” is not used for equal setpoints.

The equal setpoint is most useful for non-numeric values, such as phase rotation, IEEE-519 status, and status input states.

Not Equal Setpoint

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

The not equal setpoint is most useful for non-numeric values, such as phase rotation, IEEE-519 status, and status input states.

Examples of Setpoint Operation

Setpoint Example 1 - Over kW Forward (+)

If it is desired that setpoint 1 energizes relay 1 when kW exceeds +100kW for more than one second, and de-energizes relay 1 when kW falls below +90kW for more than two seconds, the following settings should be used.

Setpoint Example 2 - Under kW Forward (+)

If it is desired that setpoint 1 energizes relay 1 when kW is below +100kW for more than one second, and de-energizes relay 1 when kW exceeds +150kW for more than two seconds, the following settings should be used.

Setpoint Example 3 - Over kW Reverse (-)

If it is desired that setpoint 1 energizes relay 1 when kW exceeds -100kW for more than one second, and de-energizes relay 1 when kW falls below -90kW for more than two seconds, the following settings should be used.

Setpoint Example 4 - Under kW Reverse (-)

If it is desired that setpoint 1 energizes relay 1 when kW is below -100kW for more than one second, and de-energizes relay 1 when kW exceeds -150kW for more than two seconds, the following settings should be used.

Relay Operation

The Powermonitor II has two output relays. Operation of these relays is controlled by one of three mechanisms.

• Setpoint control - The relays can be independently energized or de-energized based on the Setpoint Configuration. Refer to Setpoints on page 4-16.

• Pulsed output control - One of the relays can be configured to provide a pulsed output based on the measured value for kilowatt-hours or kilovar-hours. Refer to Demand 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 Smart Communication Card 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 II relays revert to normal operation.

Data Logging

The Powermonitor II provides three data logs:

• Event log• Snapshot log• Min/Max log

Each record of the three logs is date and time-stamped to the nearest one hundredth of a second. All of the records are stored in battery powered non-volatile RAM. The data logs remain in memory as long as power is applied to the Master Module or the battery has a usable charge. In the event that power is removed from the Master Module and the battery is removed or discharged, all of the data logs will be automatically cleared.

Event Log

The Event log consists of the 100 most recent events that occurred in the Powermonitor II. This log is a circular buffer. When the buffer is full, the newest event overwrites the oldest event. A list of the events is shown in Table 4.11.

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 Smart Communication Card.

Snapshot Log

The snapshot log consists of 50 records. Each record consists of 46 parameters. The list of parameters is shown in Table 4.13 and Table 4.14. This log can be updated via a setpoint occurrence or a user-configured schedule. A user-configured schedule can be an interval ranging from one second to three years. To disable scheduled updates, set the period to zero.

The Snapshot log has two modes of operation:

• Fill and Stop• Circular

Fill and Stop fills the buffer and stops when it is full. The buffer resumes recording information when the Snapshot log is cleared.

Circular continuously fills the buffer. When the buffer is full, old data is overwritten.

The Snapshot log information is retrieved through the Smart Communication Card. All data is logged together. However, for communication purposes only, the log is divided into two blocks.

Oscillography (1403-MM only)

The Powermonitor II provides two types of oscillography. Both are triggered simultaneously and sampled at 10.8 kilo-hertz. The types are:

• Simultaneous 7-channel 2-cycle oscillogram • User configurable simultaneous 2-channel 12-

cycle oscillogram with up to eight cycles of pretrigger data

These oscillograms can be triggered manually or as the result of a setpoint. Oscillogram configuration and retrieval can only be accomplished through the Smart Communication Card.

Oscillography has two modes of operation:

• Hold• Overwrite

Hold fills a buffer when an oscillograph is triggered, and it does not allow another oscillograph to trigger until the Master Module is commanded to cancel the hold. Overwrite allows oscillographs to be overwritten when multiple triggers occur.

The pretrigger data of the 2-channel simultaneous 12-cycle oscillogram is disabled by setting the number of pretrigger cycles to a -1. This action makes the real time metering update slightly faster.

Self-test/Diagnostic Information

The Powermonitor II and its accessories have an extensive array of internal self-tests. Complete self-tests are executed at device powerup, and critical tests are continuously run during operation of the device. The results of these self-tests are used to insure the integrity of the information provided by Powermonitor II and its accessories. Improper self-test results cause the device to cease normal operation.

Bulletin Number

For the Powermonitor II, this parameter returns 1403.

Master Module Firmware Revision Number

This parameter returns the firmware revision number of the Master Module. This value is returned through the Smart Communication Card as an integer such that 1.00 is represented as 100.

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

apparent power

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

B

balanced load

An 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 value, such as minimum demand, peak demand or a ratchet clause. It can be based on Watt Demand, VA Demand, VAR Demand or some combination of these. A rate at which a transmission occurs, where one baud equals one bit per second.

burden

The electrical load placed on source of VA or the load an instrument or meter places on a current or potential transformer. All current and potential transformers have a rated burden which should not be exceeded or else transformer transformation accuracy will deteriorate.

C

capacitor

A device consisting essentially of two conducting surfaces separated by an insulating material or dielectric. A capacitor stores electrical energy, blocks the flow of direct current, and permits the flow of alternating current to a degree dependent upon the capacitance and frequency. They may also be used to adjust the power factor in a system.

connected load

The total load which a customer can impose on the electrical system if everything was connected at one time. Connected loads can be measured in horsepower, 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 to have its primary winding connected in series with a conductor carrying the current to be measured or controlled. CT’s step down high currents to lower values which can be used by measuring instruments.

current transformer ratio

The ratio of primary amperes divided by secondary amperes.

D

demand hours

The 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.

D-2 Glossary

1403-IN001A-US-P

Demand 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.

F

frequency

The 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.

H

horsepower (hp)

induction motor

An 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).

inductor

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

initiator pulses

Electrical 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.

L

lagging current

The 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 current

The 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.

load

Any device or circuit consuming power in an electrical system.

load shedding

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

load restoring

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

N

neutral

The 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.

Glossary D-3

1403-IN001A-US-P

O

ohm

The 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.

P

peak demand

The 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.

polyphase

Having 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 normally used to step down high voltage potentials to lower levels acceptable to measuring instruments. Also known as voltage transformer (VT)

potential transformer ratio

The ratio of primary voltage divided by secondary voltage.

power factor

The 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 phase angle between the fundamental voltage applied to a load and the current passing through it.

power factor correction

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

power factor penalty

The 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.

R

ratchet clause

A 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.

reactance

The 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 power

The 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.

D-4 Glossary

1403-IN001A-US-P

resistance

The 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 meter

A 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.

S

sliding demand interval

A 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.

U

unbalanced load

A 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.

V

volt-ampere (VA)

The unit of apparent power. It equals volts times amperes regardless of power factor.

volt-ampere demand

Where 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.

W

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 demand

Power 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.

wattmeter

An 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.
