  • 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. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.

  • Measuring Dew Point and Moisture in sf6 gas Gas

    Sulfur hexafluoride (gaz sf6) 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).
