The Problem with Humidity in Sulfr hexafluoride 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.

How Ambient Conditions Can Compromise Density Measurements in

Dec 13, 2016 · How Ambient Conditions Can Compromise Density Measurements in TD insulating gas-Insulated Equipment. For decades, the power transmission and distribution (TD) industry has been using sulfur hexafluoride (sf 6) as the insulator in circuit breakers, disconnectors, and switchgear. The heat transfer and dielectric characteristics of this gas are better than those of air and other gases, so Sulfr hexafluoride is a very effective arc quencher.
