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.
