Abstract: A metering device for monitoring power flow at a premises includes a metering module that measures power flow on powerlines at a premises and provides power flow data characterizing the power flow on the powerlines. The metering device also includes a communication module coupled to the metering module that transmits power flow data to a node on a meter network. The metering device further includes an energy storage element coupled to the metering module and the communication module. The energy storage element provides backup power to the metering module and the communication module in response to a voltage on the powerlines dropping below a first threshold for a time interval exceeding a second threshold, such that the metering module measures the power flow on the powerlines and provide the power flow data for a backup interval of time.

Abstract: A system and method for locating a fault in an electrical distribution system. A transient current waveform description associated with a line fault in an electrical distribution line is received. A time duration of the transient current waveform is determined based on the electrical current verses time waveform. An estimation that the line fault is likely to have occurred on one of the feeder line or the at least one lateral line is made based on a comparison of the time duration of the transient current waveform to a first threshold. An indication, based on the estimation, that the likely line fault likely occurred on one of the feeder line or the at least one lateral line is provided.
