The sf 6 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 (sf 6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of insulating gas to SOF2, SO2F2 and SO2 and other characteristic component gases.

The Problem with Humidity in sf 6 Gas-Insulated Systems

The amount of water the gas can absorb depends on the temperature of the gas. At fixed conditions, the amount of water molecules going to and from the H 2 O layer to the gas is in a dynamic equilibrium. As the gas temperature increases, more water molecules pass to the gas until a new equilibrium is reached.
