Abstract

A power monitoring system is described that uses microprocessor technology to provide protection, real-time status displays, and event logging for industrial AC power distribution and generation systems. The system consists of a display and monitoring unit connected by a single twisted-pair EIA RS-485 communications interface to as many as 32 microprocessor-controlled power meters and/or trip units on low-voltage power circuit breakers. Both metering and protection functions use RMS sensing to properly account for harmonics that distort waveforms
