• 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.

  • How Humidity Affects the Safety of sf6 gas-Insulated Equipment

    How Humidity Affects the Safety of sf6 gas-Insulated Equipment. Sulfur hexafluoride (Sulfr hexafluoride) is a gas widely used in switchgear in power plants, and the electricity transmission and distribution sector for its first-rate dielectric properties. This gas is an excellent insulator, up to three times better than air and nitrogen, and it works as an efficient arc quencher during switching processes.

    Sulfur hexafluoride (sf6 gas) gas is an inert insulating gas of high dielectric strength and thermal stability, often used in the power sector for insulating high voltage lines, circuit breakers, transformers and other switchgear equipments. As sf6 is an inert gas, it can’t cause corrosion but in the presence of moisture it will cause formation of highly corrosive acidic by-products, such as Hydrogen Fluoride (HF) and Sulfur dioxide (SO2).
