IntroductionTopics Covered by The Working GroupConclusionsSince the introduction of Gas Insulated Substations (GIS) in the late 1960s, sulphur hexafluoride (SF6) has become the favourite insulating and arc quenching medium thanks to its remarkable characteristics. However, SF6 has the major drawback of presenting a global warming potential (GWP) if released to the atmosphere, which is 23,500 times higher than CO2 and a lifetime in the atmosphere of around 3200 years according to IPCC Assessment Report 5 (AR5) from 2014. Due to these properties, it is one of th…See more on electra.cigre.orgGas insulated switchgear up to 550 kV, 63 kA, 5000 A Type 8DQ1 assets.siemens energy/siemens/assets/api/uuid:e22e1805 0b...PDF fileSince 1974 we have supplied gas insulated substations for voltage levels of up to 420 kV.

Operating PrincipleBrief HistoryDesign FeaturesGenerator Circuit BreakersHigh Power TestingIssues Related to SF6 Circuit BreakersComparison with Other TypesCurrent interruption in a high voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectricand arc quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulfur hexafluoride gas, and an arc is struck between them.
