A defect detector can receives voltage data characterizing a three-phase voltage for each of a plurality of feeder lines. The defect detector generates an alert indicating that a potential defect exists at a switch upstream of the plurality of feeder lines in response to the voltage data indicating (i) a drop in two or more phases of voltage at a given feeder line of the plurality of feeder lines occurred within a predetermined amount of time of toggling of the switch or (ii) a drop in two or more phases of voltage on at least two or more feeder lines of the plurality of feeder lines has occurred.

An energy management system receives voltage and current data from each of a plurality of fault indicators. Each fault indicator is positioned on a powerline of a power distribution system immediately upstream of a respective one of a plurality of disconnect switches. The energy management system also determines a status of each disconnect switch based on the voltage and current from the plurality of fault indicators.
