SF6 insulated quality for Ultra High Voltage

SF6 insulated quality for Ultra High Voltage

973-SF6 gas analyzer used for simultaneous measurement of humidity, sf6 purity and SO 2 concentration. Pure sf6 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
