A computer system at a substation of an electrical grid examines on-grid communication channels and for very channel, the system compares and correlates a GLA signal provided by a downstream transmitter on that channel to a reference GLA signal. The channel that provided the signal with the best correlation is mostly likely the channel with the transmitter. Thus, the feeder and phase of the signal can be determined from the correlation of signals.

1. A method for determining a phase line on which a transmitter is transmitting, comprising: receiving, by a receiver, on a first power distribution phase line of a plurality of power distribution phase lines, a first copy of a signal transmitted by one transmitter of a plurality of transmitters;digitizing the first copy of the signal;receiving, by the receiver, on a second power distribution phase line of the plurality of power distribution phase lines, a second copy of the signal transmitted by the one transmitter;digitizing the second copy of the signal;correlating, by a processing device, the first copy of the signal received on the first power distribution phase line and the second copy of the signal received on the second power distribution phase line with a reference signal; anddetermining that the one transmitter transmitted the signal on the first power distribution phase line and not on the second power distribution phase line. 2. The method of claim 1 further comprising generating, by the processing system, the reference signal by generating a plurality of chirps, each chirp comprising a signal spanning a predetermined frequency range. 3. The method of claim 2 wherein generating the reference signal by generating the plurality of chirps, each chirp comprising a signal spanning the predetermined frequency range further comprises generating the reference signal by generating at least ten chirps, each chirp of the at least ten chirps spanning a different non-overlapping predetermined frequency range. 4. The method of claim 3 wherein each chirp of the at least ten chirps spans a non-overlapping predetermined frequency range of 50 Hertz. 5. The method of claim 1 further comprising detecting, on the first power distribution phase line, a transmitted data packet transmitted by the one transmitter that follows the signal, the transmitted data packet comprising data that quantifies a measurement made by the one transmitter. 6. The method of claim 5 wherein detecting, on the first power distribution phase line, the transmitted data packet transmitted by the one transmitter further comprises detecting, on the first power distribution phase line on a high voltage side of a service transformer that steps down voltage on the first power distribution phase line, the transmitted data packet transmitted by the one transmitter on the first power distribution phase line on a low voltage side of the service transformer. 7. The method of claim 1 further comprising storing, in a grid map, data identifying the one transmitter as being coupled to the first power distribution phase line. 8. A receiver for determining a phase line on which a transmitter is transmitting, comprising: a memory; anda processor device coupled to the memory and configured to: receive on a first power distribution phase line of a plurality of power distribution phase lines, a first copy of a signal transmitted by one transmitter of a plurality of transmitters;digitize the first copy of the signal;receive on a second power distribution phase line of the plurality of power distribution phase lines, a second copy of the signal transmitted by the one transmitter;digitize the second copy of the signal;correlate the first copy of the signal received on the first power distribution phase line and the second copy of the signal received on the second power distribution phase line with a reference signal; anddetermine that the one transmitter transmitted the signal on the first power distribution phase line and not on the second power distribution phase line. 9. The receiver of claim 8 wherein the processor device is further configured to generate the reference signal by generating a plurality of chirps, each chirp comprising a signal spanning a predetermined frequency range. 10. The receiver of claim 9 wherein to generate the reference signal by generating the plurality of chirps, each chirp comprising a signal spanning the predetermined frequency range, the processor device is further configured to generate the reference signal by generating at least ten chirps, each chirp of the at least ten chirps spanning a different non-overlapping predetermined frequency range. 11. The receiver of claim 10 wherein each chirp of the at least ten chirps spans a non-overlapping predetermined frequency range of 50 Hertz. 12. The receiver of claim 8 wherein the processor device is further configured to detect, on the first power distribution phase line, a transmitted data packet transmitted by the one transmitter that follows the signal, the transmitted data packet comprising data that quantifies a measurement made by the one transmitter. 13. The receiver of claim 12 wherein to detect, on the first power distribution phase, the transmitted data packet transmitted by the one transmitter, the processor device is further configured to detect, on the first power distribution phase line on a high voltage side of a service transformer that steps down voltage on the first power distribution phase line, the transmitted data packet transmitted by the one transmitter on the first power distribution phase line on a low voltage side of the service transformer. 14. The receiver of claim 8 wherein the processor device is further configured to store, in a grid map, data identifying the one transmitter as being coupled to the first power distribution phase line.
