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 amou…See more on epa.govPublished: 2021/2/4Emissions of the powerful greenhouse gas SF6 are rising rapidly | … weforum.org/agenda/2019/10/greenhouse gas emissions climate change sf62021/8/28A recent study suggests that the UK's use of SF6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of SF6 to global warming to 0.2%. In the UK, the gas already contributes …

OriginsOperationArc InterruptionShort CircuitStandard Current RatingsTypes"Smart" Circuit BreakersOther BreakersSee AlsoAn early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses. Its purpose was to protect lighting circuit wiring from accidental short circuits and overloads. A modern miniature circuit breaker similar to the ones now in use was patented by Brown, Boveri Cie in 1924.
