The GE Multilin PQMII Power Quality Meter is an ideal choice for continuous monitoring of a

single or three-phase system. It provides metering for current, voltage, real power, reactive

power, apparent power, energy use, cost of power, power factor, and frequency.

Programmable setpoints and four assignable output relays allow control functions to be

added for specific applications. This includes basic alarm on over/under current or voltage,

unbalance, demand-based load shedding, and capacitor power factor correction control.

More complex control is possible using the four switch inputs; these can also be used for

status information such as breaker open/closed and flow information.

As a data gathering device for plant automation systems that integrate process,

instrument, and electrical requirements, all monitored values are available via one of two

RS485 communication ports running the Modbus protocol. If analog values are required

for direct interface to a PLC, any of the monitored values can output as a 4 to 20 mA (or 0

to 1 mA) signal to replace up to four (4) separate transducers. A third RS232

communication port connects to a PC from the front panel for simultaneous access of

information by other plant personnel.

Software

The EX2100e uses the ToolboxST* application for

configuration and diagnostics and retains all attributes for

high-speed analysis of rotating machinery and the enhanced

look-and-feel of plant-level Distributed Control System

software. For example, the ToolboxST application can analyze

and configure I/O modules, controllers, networks, and

operator stations for generator controls, turbine controls, and

balance-of-plant controls to simplify maintenance.

Proven Technology

While controllers, networks, I/O modules, and software tools

are upgraded, the heart of the system remains the same.

Proven control and protection algorithms remain unchanged.

Similarly, mission-critical power bridge technology is carried

over from the EX2100 power conversion assemblies.

In addition, control cabinet footprints are unchanged and

compliance to international regulations and standards is retained.

Four LEDs are located at the top of the board.  The Restart pushbutton is located immediately

below the LEDs.  The RS-232 serial port with the RJ-11 connector is the Station Manager port.

The RS-485 serial port with the 15-pin D connector located below the Station Manager port is the

module’s Downloader port.  The 14-pin AAUI connector, facing downward, is the Transceiver

port.  The Default MAC Address label is attached to the outside of the plastic housing.

Board Indicators

There are four LEDs on the Ethernet Interface:  OK, LAN, SER, and STAT.  These LEDs can be

ON, OFF, BLINKING slow, or BLINKING fast.  They indicate the state the Interface is in, traffic

on the Transceiver port and Downloader port, and when an exception event has occurred.

Restart Button

The Restart button serves four functions:  LED test, Restart, Restart and Reload, and Restart and

Enter Maintenance Utility.  The Restart button is inaccessible when the front cover of the Ethernet

Interface is closed.

Serial Ports

There are two serial ports on the Ethernet Interface:  the Station Manager Port and the Downloader Port.

The Station Manager Port.  This RS-232 port is used to connect a terminal or terminal emulator

to access the Station Manager software on the Ethernet Interface.  This port uses a  6-pin, RJ-11

connector.  The IC693CBL316 Station Manager cable is ideal for connecting to this port .

The Firmware Upgrade Port.  The 15-pin, D-type, RS-485 port is used to connect to the PC

Downloader in case the communications software in the Ethernet Interface needs to be updated.

Use the IC690ACC901 miniconverter/cable kit for this connection.

Alternate Phase Distance

Two independent phase distance elements provide time-delayed backup protection

for generator faults that are not cleared by the main system and generator protection.

This distance characteristic compensates for unit delta/shunt power transformers

located between the generator and the end of the protection zone.

Sensitive Directional Power

The 489 provides low forward and reverse power elements to prevent generator

movement from damaging the prime mover.

Each element has separate power pickup level and operating delay settings for alarms and trips.

Circuit Breaker Faults

The embedded circuit breaker fault feature in the 489 improves system reliability

without the additional cost of providing a separate circuit breaker fault relay.

When a circuit breaker fault is detected, the 489 can be configured to operate

one of its four available digital outputs to signal upstream equipment to quickly isolate the fault.

The 489’s protection features include:

Generator stator differential

The 489 uses high speed dual slope differential protection to detect and clear stator phase faults.

Stator phase faults. Advanced CT saturation detection algorithms provide

additional supervision through the use of directional checks that

ensures that the fault occurs inside the generator before triggering a trip,

thus maintaining immunity to saturation that may be caused by external disturbances.

100% Stator Ground

100% stator ground fault protection is provided by an overvoltage element and an

adaptive differential voltage function that responds to third harmonic imbalances at the machine

terminals and neutral.

The 489 will compare the machine neutral voltage with the grounding

current to determine if the ground fault is internal or external to the generator.

Alternate Phase Distance

Two independent phase distance elements provide time-delayed backup protection

for generator faults that are not cleared by the main system and generator protection.

This distance characteristic compensates for unit delta/shunt power transformers

located between the generator and the end of the protection zone.

Applications

– Synchronous or induction generators operating at 25Hz, 50Hz or 60Hz

– Primary or backup protection in cogeneration applications

Protection and control

The 489 generator protection system provides comprehensive protection,

metering and monitoring functions for small and medium-sized synchronous or

induction generators operating at 25. 50 or 60 Hz.

The 489 is ideal for primary or standby generator protection as well as cogeneration applications.

The 489’s protection features include:

Generator stator differential

The 489 uses high speed dual slope differential protection to detect and clear stator phase faults.

Stator phase faults. Advanced CT saturation detection algorithms provide

additional supervision through the use of directional checks that

ensures that the fault occurs inside the generator before triggering a trip,

thus maintaining immunity to saturation that may be caused by external disturbances.

100% Stator Ground

100% stator ground fault protection is provided by an overvoltage element and an

adaptive differential voltage function that responds to third harmonic imbalances at the machine

terminals and neutral.

The 489 will compare the machine neutral voltage with the grounding

current to determine if the ground fault is internal or external to the generator.
