Effect of Moisture inside sf6 gas Gas Insulated Switchgear

Nov 17, 2011 · However when there is a leakage and air enters the insulating gas gas compartment, it will bring along the moisture. Air and moisture will prevent the Sulfur atom and Fluorine molecule to combine back. In immense heat, highly mobile hydrogen molecules will combine with Fluorine molecule and form Hydrogen Fluoride which is corrosive in nature.
