Secondary arcs are a type of alternating-current electric arc burning in open space, the arcing times of which are closely related to the transient of their currents. To elucidate the formation mechanism of the transient, the secondary current was fi

To guarantee the uniform distribution of transient recovery voltage for double-break circuit breaker, grading capacitors are often installed in parallel with each interrupter unit. In this study, the influence of the capacitors on the secondary arc i

The extended grading capacitor (GC) for multi-break circuit breaker is a cost-effective method to suppress secondary arc. Since the integration of GC alter the topology of the system, the existing adaptive auto-reclosure scheme should be changed. Con
