  • Sulfur hexafluoride - Wikipedia

    From Wikipedia, the free encyclopedia Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), 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.

    Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.

    Sulfur hexafluoride (Sulfr hexafluoride) is an inert, volatile tracer and has been deliberately added to water bodies to determine kw. Experiments in enclosed lakes showed a good correlation between kw and wind speed and a parameterization of kw developed from these studies predicts a similar global mean (12 cm h −1) to that obtained from the radon data.
