PQM-T20-C

GE Multilin has set a new standard in metering technology with the introduction of the PQM II. This meter,

designed on the latest industry specifications, provides accurate and reliable three-phase power metering

with an optional Ethernet and fiber communications module in a small and modern package. The PQM II can

be used for a variety of applications including metering of distribution feeders, transformers, generators and motors.
Robust Metering and Power Quality Capabilities in One Package
The PQM II is an ideal choice when continuous monitoring of a three phase
system is required. It provides metering for current, voltage, real and reactive power,
energy use, cost of power, power factor and frequency. Waveform capture and
Voltage Disturbance Recorder continuously monitors power quality. Programmable
setpoints and 4 assignable output relays allow control functions to be added for specific applications.
