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: 2021/2/4The decomposition products of sulfur hexafluoride (SF 6): Reviews … researchgate.net/publication/244266108_The_decomposition_products_of...The most common insulating gas used in GIS is Sulfur hexafluoride (SF 6 ) gas, which is widely used as an effective electrical insulation as well as an arc quenching medium [5].
