when permanent fault occurs, reclosure will fail, the circuit breaker must break short-current continuous twice, this condition will reduce the lifetime and breaking capacity of the circuit breaker. A scheme of Adaptive Auto-reclosure Technique of Distribution Line is put forward in order to distinguish the permanent fault or the transient fault, by distinguishing the transient characteristic of voltage and current of capacitor. when permanent fault occurs, it blocks reclosure; when transient fault occurs, it opens reclosure. The feasibility of the scheme under different conditions is analysed by the simulation.
