摘要： 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.
