fluke HYBRID GIS INSULATED SWITCHGEAR Maintance

Oct 23, 2020As vacuum technology is not available for high voltage, so for GIS or gas insulated switchgear system above 72.5 KV, only sf6 is used both for interruption medium and insulation. There are different types of gas insulated metal enclosed switchgears available depending upon their constructional feature.
