How Humidity Affects the Safety of insulating gas-Insulated Equipment

How Humidity Affects the Safety of Sulfr hexafluoride-Insulated Equipment. Sulfur hexafluoride (sf 6) 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.

The Problem with Humidity in gaz sf6 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.
