| Abstract: | The instantaneous overcurrent release and short-time delay overcurrent release were setting reasonably,so that circuit-breaker has overcurrent selectivity.The energy selectivity and the zone selective interlock technology were described.The technology could improve the short-circuit overcurrent selectivity of circuit-bre aker and ensure the safety of power distribution system. |
