    1 OVERVIEW 1.1 INTRODUCTION 1.1.1 DESCRIPTION The GE Power Management PQM 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.
