  • Measurement of Water Vapor in Sulphur Hexafluoride, SF6

    Measurement of Water Vapor To ensure that corrosive electrolytes remain at low concentration levels, it is important to make periodic measurements of the water vapor content of the gas used within the SF6 filled equipment. Chilled mirror technology is commonly used as an accurate, reliable, and robust method for measurement of water vapor in SF6. While the initial cost to obtain the chilled mirror equipment is somewhat higher than systems

  • 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.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
