  • Patent number: 11416119
    Abstract: Systems and methods to determine an event location on a feeder line segment that is downstream of a feeder line branch. A first indication of an event is received from a sensor located on a feeder line upstream of the feeder line branch. A status of a monitored segment downstream of the feeder line branch is determined based on receiving the indication. The monitored segment is determined to be a particular branch based on locations of the feeder line branch, status sensors downstream of the feeder line branch, and location data of segments downstream of the feeder line branch. The event is determined to have occurred on a determined segment downstream of the feeder line branch based on the status of the monitored segment and on which segment is the monitored segment. An indication that the event occurred on the determined segment is provided based on determining the monitored segment.

  • Publication number: 20210072303
    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.
