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.

Description. 973-Sulfr hexafluoride gas analyzer used for simultaneous measurement of humidity, SF 6 purity and SO 2 concentration. Pure SF 6 is the standard filling within GIS, but over time gas compartments become contaminated with water vapor (H 2 O) through permeation and by desorption from internal materials. Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur and
