Abstract
An electrical phase (e.g., a phase from among three-phase power) connected to an electrical meter may be determined. In one example of the techniques, changes in energy or power (e.g., a derivative or differences) may be determined based at least in part on measurements from each of a plurality of meters. Changes in energy or power may be determined based at least in part on electrical transmissions measured at each of the phases of a feeder. A meter may be selected from among the plurality of meters. For each of the plurality of electrical phases, the changes in energy or power measured by the meter may be compared or correlated to the changes in energy or power measured at the feeder. A phase that is connected to the meter may be determined, from among the plurality of electrical phases, based at least in part on the comparisons or correlations.
