Abstract
A system and method for clearing overcurrent in a power distribution network. The network includes a feeder, a lateral line coupled to the feeder, a lateral line current interrupting device provided where the lateral line is coupled to the feeder, a plurality of service lines coupled to the lateral line, a distribution current interrupting device provided where a service line is coupled to the lateral line and a distribution transformer provided at each location where a service line is coupled to the lateral line. The method includes setting an operating time of the lateral line interrupting device to be longer than an operating time of the distribution interrupting devices, detecting overcurrent by the lateral line interrupting device and at least one of distribution interrupting devices, and operating the at least one the distribution interrupting device and not operating the lateral line interrupting device in response to detecting the overcurrent.
