sf6 circuit breaker environmental impact training Electrical industry
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 electSee more on epa.govPublished: 04/02/2021Climate change: Electrical industry's 'dirty secret bbc/news/science-environment-4956719713/09/2019Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents.

22/05/2021The vast majority of high-voltage circuit breakers use SF 6 as the quenching and insulating medium. During the interruption process, when the arc is burning between contacts, SF 6 is decomposed in the plasma into sulphur and fluorine atoms. Once the gas has cooled down after interruption. the majority of S and F recombine forming SF6
