best price cf4 check for leaks for gas-insulated switchgears

Various arguments exist around SF6 Gas Insulated (GIS) and Air Insulated (AIS) switchgear. Recently we had to change a GIS design to AIS due to an instruction from one of our clients. His concern is the global warming potential of SF6. While understanding the clients reasons, I'm not convinced on the argument.

  • Effect of Moisture inside SF6 Gas Insulated Switchgear

    Nov 17, 2011 · 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.
