Abstract
The present invention relates generally to detecting energy theft within an energy distribution system and more particularly to systems and methods for detecting energy discrepancies in voltages and/or currents reported by electric meters present in a distribution circuit, without requiring installation of additional hardware at the transformer. Typically, the location of each of at least two meters is determined with respect to a transformer. The line resistances within the distribution circuit are determined starting with a line resistance farthest from the transformer. Estimated line voltages are determined for at least one electric meter using the estimated line resistances, and the estimated voltages are compared to actual voltage readings for the at least one electric meter. The existence of line loss is determined based on this comparison.
