Abstract

There is disclosed a method of metering electricity that includes calculating a first accumulated in-phase current indicative of a non-voltage component of energy flow to one or more customer premises during a period of time by a distribution transformer meter (DTM) coupled to a distribution transformer (DT) and calculating second accumulated in-phase current (AIPC) indicative of a non-voltage component of energy flow during a period of time by a feeder current meter coupled to a feeder line. The method further includes transmitting the first AIPC and the second AIPC to a data collecting computing device and comparing the first AIPC with the second AIPC to determine if electricity theft has occurred.
