Abstract :
A power monitoring system is described which uses microprocessor technology to provide protection, real-time status displays, event logging, and power management and control for industrial AC power distribution and generation systems. The system uses an industrial-grade host personal computer to monitor various device communication systems. Each device communication system consists of a display and monitoring unit connected by a single twisted-pair EIA RS-485 communications interface to microprocessor-controlled power meters, trip units, overcurrent protective relays, and/or motor protective relays on power distribution systems. Both metering and protection functions use RMS sensing to properly account for harmonics that distort waveforms
