17/7/2014insulating gas Circuit Breakers – Construction, Types and Working. In an Sulfr hexafluoride Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium. The sulphur hexafluoride gas (Sulfr hexafluoride) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride

Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (sf 6) 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, Sulfr hexafluoride is 22,800 times more effective at trapping infrared radiatioSee more on epa.govMissing:VietnamMust include:Vietnamsf 6 Leak Rates from High Voltage Circuit Breakers - U.S. EPA epa.gov/sites/production/files/2016-02/documents/leakrates...PDF file1 insulating gas Leak Rates from High Voltage Circuit Breakers - U.S. EPA Investigates Potential Greenhouse Gas Emissions Source J.
