POWER DISTRIBUTION SYSTEMS AND METHODS OF PERFORMING GROUND FAULT DETECTION IN POWER DISTRIBUTION SYSTEMS WITH A COMMUNICATION NETWORK

摘要

A method of operating an electrical power distribution system including a plurality of circuit protection devices and an additional circuit protection device communicatively coupled by a communications network is described. The method includes transmitting, by each circuit protection device of the plurality of circuit protection devices, an electrical current communication to the communication network, the electrical current communication including an indication of an electrical current detected by the transmitting circuit protection device formatted according to a network communication protocol of the communication network. The additional circuit protection device receives the electrical current communications from the plurality of circuit protection devices and determines, based on the received electrical current communications, whether a ground fault condition exists in the electrical power distribution system.
