History of SF6Chemical Properties of SF6 GasElectrical Properties of SF6 GasSF6 or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that SF6 gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluo…See more on electrical4uBasic Definitions – Circuit BreakerDefined Electricdefinedelectric/basic-definitions-circuit-breakerOriginsOperationArc InterruptionShort Circuit CurrentStandard Current RatingsTypes of Circuit BreakerOther BreakersAn early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses.
