Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (SF6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on SF6 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, SF6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of c…See more on epa.govPublished: 2021/2/4Missing:IntroductionMust include:IntroductionRESEARCH OF SF6 GAS COMPREHENSIVELY ONLINE …cired.net/publications/cired2005/papers/cired2005_0073.pdfPDF file1.2 Leak detecting of SF6 gas Now what used for detecting leakage of SF6 gas at home and abroad mainly includes leak detecting and density relays.

Immediately after colliding with the molecule of SF6 gas, free electron absorption takes place and the electron is then converted into a negative ion – that weighs a lot more than a free electron. This is the reason why the charged particle mobility which is solely responsible for current conduction through SF6 gas – needs only a minimal amount of SF6 gas compared to when other gases are
