IET Digital Library: IET Generation, Transmission ... stainless steel needle-plate electrode was used to simulate the insulation defects of metal protrusions in GIS. SOF 2, SO 2 F 2, CO 2, SO 2, and CF 4 data generated from SF 6 decomposition were obtained under different pressures. The variation law of component concentration and effective characteristic ratio with pressure were analysed in detail.[email protected]

Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
