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 …See more on en.wikipedia.orgEstimated Reading Time: 12 minsRecent trend and future perspectives in electrical insulation … ieeexplore.ieee.org/document/57394212011/3/24Abstract: The recent technical trend of sulfur hexafluoride (SF 6) substitutes and future perspectives in the development of electrical insulation techniques for electric power equipment are reviewed and discussed.
