The Problem with Humidity in insulating 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.
