High Voltage, EarlyView.ABSTRACT Large‐capacity generator circuit breaker (GCB) based on vacuum interrupter technology is the key power equipment to ensure the safe operation of the power system. When the short‐circuit current was forced to cross zero, the large‐capacity GCB was difficult to generate a zero‐voltage environment through freewheeling, the vacuum interrupter (VI)
