A review on condition monitoring of GIS

Abstract:

Baseload power generation plants like thermal, coal, nuclear etc. contribute to around 30-35 % of the total power demand. Electric power grids depend on these power plants to provide reliable electric power supply with good power quality to the end consumer. To ensure reliable power generation, critical components of these plants need to be monitored continuously. In the distribution side of power system networks, medium voltage switchgear is being considered as the vital component to be looked at for industrial applications. In the past research studies on MV switchgear have given enough insight into various kinds of failures associated with it. This paper focuses on Gas insulted Switchgear (GIS) failure causes, failure phenomena, sensing techniques and signal processing tools for online diagnosis.
