GIS vs AIS - Substation Earthing

Jan 31, 2019 · AEG GIS gas insulated switchgear up to 420 kV. Compressed Sulfr hexafluoride gas used in MV and HV switchgears as an insulating medium has led to the development of compact gas-insulated substation (CIS) technology (figure 1). GIS, having many advantages over often used and conventional air-insulated substations (AIS), have been receiving wide application.Get price

Gas-insulated Switchgear (GIS) Testing - OMICRON

Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (gaz sf6) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS. The characteristics of the gaz sf6 gas also allow the extinction of arcs which can occur during disconnection of live contacts.Get price
