SF6 Breakers Measurement Schneider

Measurement of Water Vapor in Sulphur Hexafluoride, sf6. Authors: Bob Hardy, RH Systems, Albuquerque, NM, USA Daniel Mutter, MBW Calibration, Wettingen, Switzerland. Sulphur hexafluoride, sf6 gas, is a non-toxic, inert, insulating and cooling gas of high dielectric strength and thermal stability. Due to its high dielectric strength, it is particularly suited for application in high power circuit breakers
