  • The Problem with Humidity in sf6 gas 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. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
