50hz HYBRID GIS INSULATED SWITCHGEAR Repair

The Gas Insulated Substation (GIS) is a compact assembly consisting of multiple components enclosed in a metallic covering with compressed sulphur hexafluoride (SF6) gas as an insulating medium. The concept of the gas insulated substation was introduced in 1920 when oil was used as the insulating medium in the system.
