Gas Insulated Switchgear detection system for Maintenance

Gas-insulated Switchgear (GIS) Testing. 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 (SF6) gas.
