Gas-insulated switchgear (GIS) has solved many problems by providing a far safer and more compact solution. The only significant drawback has been the use of Sulfr hexafluoride gas, which requires very careful handling to avoid environmental issues. That drawback has been greatly reduced with AirPlus gas, now available in ABB GIS.

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.
