Abstract
A system and method for isolating a fault in a power distribution network. The network includes a power line, a plurality of transformers electrically coupled to and positioned along the power line, and a recloser coupled to the power line. Each transformer has a unique address identifying the transformer and includes a source side switching device at an upstream side of the transformer and a load side switching device at a downstream side of the transformer. The method includes learning the address by each transformer of its immediate neighbor transformers, detecting overcurrent by some of the switching devices as a result of the fault, detecting loss of voltage by some of the switching devices and sending clear to close messages to selectively open and close certain ones of the switching devices using the transformer addresses to limit the number of switching devices that are operated and to isolate the fault.
