OverviewOperating 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 dielectric and 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 brea…
