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.

A recent study suggests that the UK’s use of gaz sf6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of sf6 gas to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.
