Abstract: 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.

Abstract: A storm damage response system includes a storm ensemble database that stores ensemble forecast models associated with respective potential storm paths of a given storm across a geographic area and an equipment database that stores equipment data associated with location and characteristics of power-providing equipment in the geographic area. A storm damage model algorithm generates a storm response plan comprising an operational procedure for repairing or maintaining power transmission and distribution electric systems to mitigate storm damage impact based on generating a probabilistic model for each of the ensemble forecast models based on the equipment data and calculating a statistical impact value associated with the probabilistic model based on an aggregate of iterative probabilistic simulations for the respective ensemble forecast model. The storm response plan can be generated based on the relative statistical impact value of the probabilistic model of each of the ensemble forecast models.

Abstract: A storm damage response system includes a storm ensemble database that stores ensemble forecast models associated with respective potential storm paths of a given storm across a geographic area and an inventory database that stores inventory data associated with location and characteristics of power-providing equipment and characteristics of a consumer population in the geographic area. A storm damage model algorithm generates a storm response plan comprising an operational procedure for repairing or maintaining power transmission and distribution electric systems to mitigate storm damage impact based on generating a probabilistic model for each of the ensemble forecast models based on the inventory data and calculating a statistical impact value associated with the probabilistic model based on an aggregate of iterative probabilistic simulations for the respective ensemble forecast model.
