The power quality meter (PQM) is an ideal choice when continuous monitoring of an electrical parameters is required for industrial use or revenue accuracy are required. It provides metering for current, voltage, real and reactive power, energy use, cost of power, power factor and frequency. With programmable setpoints and 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.
