gaz sf6 Gas Measurement Theory - MBW Calibration AG

Measurement of Water Vapor in Sulphur Hexafluoride, SF 6. Authors: Bob Hardy, RH Systems, Albuquerque, NM, USA Daniel Mutter, MBW Calibration, Wettingen, Switzerland. Sulphur hexafluoride, SF 6, 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 as well as in high-voltage cables, transformers, and switchgears.Get price
