Power Equipment Diagnosis & preventive System for GIS and Transformer

Abstract

This paper deals with development, testing, implementation and on-site operation of the Diagnostic monitoring system for GIS and Power transformer. Our diagnostic monitoring system allow the following: monitoring of circuit breaker with parameters about the coil opening/closing time, full breaking/opening time and slope of stroke for GIS, tap changer with the operating time, bushing, and Instrumentation of dissolved gas analysis (DGA) for the transformer. As our system is on-line monitoring, the system support diagnosis analysis, managing event/alarm, trend and etc. Also, it is installed and on-site operation.
