Abstract
Systems, methods, and apparatus for utility meter phase identification are provided. A utility meter may receive, from a remote system, a plurality of reference signals for respective zero crossings for a plurality of phases in a multiple-phase power system. The reference signals may be generated utilizing a precision time source. The utility meter may also receive a precision time signal from a time source. The precision time signal may be utilized to time stamp a zero crossing of a voltage signal at the meter, and the time stamped voltage signal may be compared to the plurality of reference signals in order to determine a phase to which the utility meter is connected.
