The Problem with Humidity in sf 6 Gas-Insulated Systems

To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed

Why Sulfr hexafluoride or Sulfur Hexafluoride gas is better for arc

sf6 gas decomposes in the high temperature of an electric arc or spark, but the decomposed gas recombines back into sf6 gas so well that it is not necessary to replenish the Sulfr hexafluoride in GIS. There are some reactive decomposition byproducts formed because of the interaction of sulfur and fluorine ions with trace amounts of moisture, air, and other contaminants.
