973-SF6 Gas Analyzer | SF6 Humidity & Purity Test ... 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 ...

SF6 Circuit Breakers - Construction, Types and Working an SF6 Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium.. The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (SF6) gas and an arc is struck between them.
