sf6 gas insulated switchgear Grid Solutions for Ultra High Voltage

Since gas insulated switchgear (GIS) is filled with SF6 gas as insulation, partial discharge can be caused by floating particles, loose or broken components such as a piece of metal shaving that gets too close to a conductor. Partial discharge can occur in different type of medium whether it be in a solid, gas or liquid.
