Abstract: In vacuum circuit breakers, the anodes often become active with the heating of high current constricted arc and generate secondary plasma, which has a negative impact on interruption. The ...

Electrical power transmission networks are protected and controlled by medium and high-voltage circuit breakers. Breakers are meant to make and break the flow of electrical currents in transmission ...

Abstract: In high-voltage switchgear, the external busbars and conductive rods of a handcart-type vacuum circuit breaker form a “U” shaped loop. During the interruption of short-circuit currents, an ...
