Abstract: The hybrid circuit breaker (HCB) which consists of SF6 interrupter (GI) and vacuum interrupter (VI) connected in series has been put forward to be applied in HVDC system. The paper analyses ...

Operators discovered that vacuum breakers intended to maintain the structural integrity of the containment system during major events were inoperable because certain valves were not reopened after ...

Abstract: For phase-controlled vacuum breakers, the acting time of the actuator should be precise. The variation of capacitor voltage, capacitance, and environmental temperature impact the dispersion ...
