Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (Sulfr hexafluoride) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on Sulfr hexafluoride 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, gaz sf6 is 22,800 times more effective at trapping infrared rSee more on epa.govMissing:ColombiaMust include:ColombiaDevelopment Sf6 Alternative Gases in Switchgears - Switchgear switchgearcontent/2019/11/23/1698/development-sf6-alternative-gases-in...23/11/2019Development Sf6 Alternative Gases in Switchgears.
