  • Modeling and Simulation of Sulfur Hexafluoride (SF

    Sulfur hexafluoride (Sulfr hexafluoride) was first prepared by H. Mossian in 1902 and commercial production of Sulfr hexafluoride was initiated by Allied-Signal Inc., U.S.A., in 1948. The basic properties of insulating gas at 25 oC and 1 atm are summarized in Table 1 [Marshall, 1976; Takaiki, 1976; Grant, 1995]. insulating gas is a colorless, odorless and tasteless gas

    Sulphur hexafluoride is an inorganic, colourless, odourless, non-flammable gas which is an excellent electrical insulator. It is an extremely potent greenhouse gas therefore it is important to minimise leaks of it to the environment. It absorbs strongly in the infrared, so NDIR sensors are ideally suited to detecting it at low ppm concentrations.
