Effect of Moisture inside Sulfr hexafluoride Gas Insulated Switchgear

Nov 17, 2011 · When switching is done in a gaz 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 insulating gas gasses will quench the arching in order to prevent it from spreading.Get price
