Introduction to GIS On – line Monitoring System
GIS (Gas – Insulated Switchgear) is a key equipment widely used in power systems. It integrates circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, surge arresters and busbars into a metal enclosure filled with sulfur hexafluoride (SF₆) gas, which has high reliability and compactness. GIS On-line Monitoring System

The GIS on – line monitoring system is designed to continuously monitor the operating status of GIS equipment in real – time. It can detect various parameters such as temperature, partial discharge, gas leakage, and pressure. By analyzing these monitored data, potential faults can be predicted in advance, maintenance plans can be optimized, and the safe and stable operation of the power grid can be ensured. This system helps to reduce maintenance costs, improve power supply reliability, and prevent large – scale power outages.
