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 stru…See more on en.wikipedia.orgEstimated Reading Time: 12 mins(PDF) Design and Building a High Voltage Switchgear Safety System researchgate.net/publication/344049996_Design_and_Building_a_High_Voltage...Design and Building a High Voltage Switchgear Safety System.
