Gas Insulated Switchgear density sensor for testing

Gas Insulated Switchgear density sensor for testing

Due to the dielectric properties of the SF6 gas, partial discharge activity in gas insulated switchgear covers a bandwidth of well beyond 2 GHz. The mechanical properties of the components of gas insulated switchgear further allow transmission of such signals over a distance of a couple of meters.
