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 insulating gas gas also allow the extinction of arcs which can occur during disconnection of live contacts.
