MBW Sf6 - GIS

Pure Sf6 is the standard filling within GIS , but over time gas compartments become contaminated with vapor (H2O) through permeation and by desorption from internal components. - Whilst water vapor and Sf6 do not normally react with each other, in the presence of high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur and fluorine from Sf6 to from decomposition by-products.
