Gas-Insulated Switchgear Testing
Compact gas-insulated switchgear (GIS) represent a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of insulating gas, the most common of which is sulfur hexafluoride (SF6). A perfect condition of the GIS is essential for its reliable operation. A GIS malfunction would be a calamity and therefore tests are inevitable to make such an event as unlikely as possible.
