International Classification:

G01R 31/08
G01R 22/10
G01R 19/25
G01R 22/06
H02J 3/00

Abstract:

Some embodiments of the invention include a method and system for metering an electrical grid comprising at least one processor executing instructions from a non-transitory computer-readable storage medium of an electrical grid fault detection system. In some embodiments of the system, the instructions cause a processor to calculate a prediction of whether power delivery to at least a portion of the electrical grid is functioning abnormally using voltage sensing devices coupled to at least one feeder, where one or more of the voltage sensing devices are responsive to a determination that the power delivery is functioning abnormally. Further in some embodiments, the determination includes the electrical grid fault detection system receiving at least one signal or voltage reading from the electrical grid based at least in part on a sensed or received voltage level or range of voltage level.
