Introductionsf6 gas GasSulfr hexafluoride Circuit Breaker TypesConstruction and Main ComponentsIn power systems, circuit breakers are used to switch electrical equipment and networks under normal and fault conditions. The primary function of a circuit breaker is to interrupt the flow of current (load or short circuit) by opening its contacts and thereby isolating the switched parts of the system. The design and working of a circuit breaker depend on its application and voltage rating. Moulded case technology (with air at atmospheric pressure) is used at low voltages (< 10See more on savreeSulfr hexafluoride Circuit Breaker Testing And Maintenanceindustrialtests/sf6-circuit-breaker-testing-maintenanceSulfr hexafluoride Circuit Breaker Testing And Maintenance.
