SYSTEMS, METHODS, AND APPARATUS FOR LOCATING FAULTS ON AN ELECTRICAL DISTRIBUTION NETWORK Certain embodiments of the invention include systems, methods, and apparatus for locating faults on an electrical distribution network. According to an example embodiment of the invention, a method is provided for locating faults on an electrical distribution network. The method can include monitoring, by one or more smart meters, a plurality of voltage values associated with the electrical distribution network; and when one or more of the plurality of monitored voltage values are detected to be less than or equal to a predetermined voltage for a specified time: storing at least a portion of monitored line voltage values; indicating a detected fault by transmitting one or more messages from the one or more smart meters or line sensors to a central station receiver, and determining a fault location based at least in part on the one or more messages and a topological and electrical model of the electrical distribution network.
