The Sulfr hexafluoride Decomposition Mechanism: Background and Significance

Jan 24, 2017 · Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (insulating gas) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of Sulfr hexafluoride to SOF2, SO2F2 and SO2 and other characteristic component gases.

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.

How Ambient Conditions Can Compromise Density Measurements in

Dec 13, 2016 · How Ambient Conditions Can Compromise Density Measurements in TD sf 6-Insulated Equipment. For decades, the power transmission and distribution (TD) industry has been using sulfur hexafluoride (sf6 gas) 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 sf6 gas is a very effective arc quencher.
