Effect of Moisture inside SF6 Gas Insulated Switchgear· When switching is done in a SF6 Gas insulated switchgear, arching will occur. This is because there is a high impedance on the breaker switch when the switch is opened and high voltage current tries to flow through the impedance. The arching release immense heat and SF6 gasses will quench the arching in order to prevent it from spreading.
