Safe and efficient sf6 is gas Mexico

Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (sf6 gas) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on sf 6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to-date. Over a 100-year period, Sulfr hexafluoride is 22,800 times more effective at trapping infrared rSee more on epa.govMissing:gas MexicoMust include:gas MexicoSulfur hexafluoride - Wikipedia en.wikipedia.org/wiki/Sulfur_hexafluorideSynthesis and ReactionsApplicationsGreenhouse GasPhysiological Effects and PrecautionsSee AlsoFurther ReadingExternal LinksSulfur hexafluoride on Earth exists primarily as a man-made industrial gas and has also been found to occur naturally. sf6 gas can be prepared from the elements through exposure of S8 to F2. This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901.

Abnormal LeakageInternal FaultExternal FireThe method of risk assessment is similar to that used in section "leakage from gaz sf6 – filled equipment" which deals with normal leakage. The same case study data will be used for high and medium voltage situations. In the calculations that follow it is assumed that all of the sf6 gas in one circuit-breaker escapes suddenly and it is again assumed that the switch-room is sealed and that ventilation is inoperative.
