A method for determining a phase line on which a transmitter is transmitting, comprising: generating, by a processing system comprising a processing device, a reference signal ; monitoring, by the processing system, a plurality of power distribution phase lines for transmitted signals transmitted by respective transmitters of a plurality of transmitters coupled to the plurality of power distribution phase lines, subsets of the plurality of power distribution phase lines composing a plurality of corresponding feeder lines such that each feeder line of the plurality of corresponding feeder lines comprises a corresponding subset of power distribution phase lines of the plurality of power distribution phase lines; detecting, on a first power distribution phase line of the plurality of power distribution phase lines, a transmitted signal transmitted by one transmitter of the plurality of transmitters; detecting, on a second power distribution phase line of the plurality of power distribution phase lines, the transmitted signal transmitted by the one transmitter; correlating the transmitted signal detected on the first power distribution phase line and the transmitted signal detected on the second power distribution phase line with the reference signal ; and determining, based on the correlation between the transmitted signal detected on the first power distribution line and the transmitted signal detected on the second power distribution phase line with the reference signal, that the one transmitter transmitted the transmitted signal on the first power distribution phase line and not on the second power distribution phase line. generating, by a processing system comprising a processing device, a reference signal ; monitoring, by the processing system, a plurality of power distribution phase lines for transmitted signals transmitted by respective transmitters of a plurality of transmitters coupled to the plurality of power distribution phase lines, subsets of the plurality of power distribution phase lines composing a plurality of corresponding feeder lines such that each feeder line of the plurality of corresponding feeder lines comprises a corresponding subset of power distribution phase lines of the plurality of power distribution phase lines; detecting, on a first power distribution phase line of the plurality of power distribution phase lines, a transmitted signal transmitted by one transmitter of the plurality of transmitters; detecting, on a second power distribution phase line of the plurality of power distribution phase lines, the transmitted signal transmitted by the one transmitter; correlating the transmitted signal detected on the first power distribution phase line and the transmitted signal detected on the second power distribution phase line with the reference signal ; and determining, based on the correlation between the transmitted signal detected on the first power distribution line and the transmitted signal detected on the second power distribution phase line with the reference signal, that the one transmitter transmitted the transmitted signal on the first power distribution phase line and not on the second power distribution phase line. <EOS>
