Product Description


GE PQM - T20 - C - A Power Quality Monitor
PQM II Series, Real - time Power Quality Monitoring & Control for Three - Phase Electrical Systems
1. Product Overview

The GE PQM - T20 - C - A is a high - performance three - phase power quality monitor of the GE PQM II Series, engineered for real - time monitoring, analysis and control of electrical power systems in industrial, commercial and utility applications. It can accurately measure voltage, current, real/reactive/apparent power, energy consumption, power factor and frequency. It also has the capabilities of harmonic analysis (up to 51st harmonic), voltage sag/swell capture and event logging. Equipped with flexible I/O interfaces and multiple communication protocols, it supports seamless integration with SCADA and PLC systems, and enables functions such as load shedding, power factor correction and alarm triggering through programmable setpoints, thus effectively safeguarding the stable operation of electrical equipment and improving power utilization efficiency.
