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.

gaz sf6 Gas Hazards and How to Avoid Them - WIKA blog

Sulfur hexafluoride, a highly effective insulator and arc quencher, is commonly found in the power transmission and distribution industry. But to protect equipment, personnel, and the environment, users must be aware of the common sf 6 gas hazards and how to avoid them. Sulfur hexafluoride (SF 6), when sealed inside power transmission and distribution (TD) equipment, insulates switchgears, circuit breakers, and disconnectors by quenching dangerous arcs.
