Method for identifying phase of electric energy meter and related product

The invention discloses a method for identifying phases of an electric energy meter and a related product. The method comprises the following steps: acquiring a phase voltage data sequence of each phase in a multi-phase transformer in a target power utilization area and a user voltage data sequence monitored by the electric energy meter, which are acquired in the same acquisition time range; aiming at the phase voltage data sequence of each phase in the multi-phase transformer, respectively calculating the distance between the phase voltage data sequence and a user voltage data sequence based on at least two different distance calculation modes so as to obtain a plurality of distances corresponding to each phase of the multi-phase transformer; and determining the phase to which the electric energy meter belongs according to the plurality of distances corresponding to each phase of the multi-phase transformer. According to the scheme, multiple similarities between the phase voltage data sequence and the user v
