A method and apparatus for restoring power to loads connected to a feeder powered by a power source. The feeder is provided with a plurality of switching devices and a master electronic device which is in operative communication with the switching devices and has a plurality of power restoration plans stored therein. Upon occurrence of a fault in a zone of the feeder, the identity of the switching device which is closest to and upstream from the faulted zone relative to the power source is used in order to select a power restoration plan and restore power to some or all the loads connected to non-faulted zones of the feeder from one or more additional feeders.

A preferred embodiment of control unit for a power-distribution network comprises a processor, a memory-storage device electrically coupled to the processor, a set of computer-executable instructions stored on the memory-storage device, and an input/output interface electrically coupled to the processor. The control unit receives data from a plurality of switching devices of a power-distribution network, identifies ones of the switching devices located immediately up-line and down-line of a fault in a faulted section of the power-distribution network based on predetermined characteristics of the data, and generates and sends a first control input to at least one of the switching devices located immediately up-line and down-line of the fault to cause the at least one of the switching devices to open and thereby isolate the faulted section from a second section of the power-distribution network.
