Title: SYSTEM AND METHOD FOR DETERMINING A PHASE CONDUCTOR SUPPLYING POWER TO A DEVICE
Abstract:
A system and method for determining one of a plurality of power line conductors to which a remote device is electrically connected is provided. In one embodiment the method includes transmitting a data beacon, determining a relative time period associated with each power line conductor between a zero crossing of the voltage of the power line conductor and the transmission of the data beacon, receiving the data beacon with the remote device, determining a first time period between reception of the data beacon and a zero crossing of a voltage at the first remote device, and transmitting data of the first time period to a computer system. The method further includes with the computer system receiving the data of the first time period, determining that the first time period satisfies a similarity threshold with a relative time period associated with a first power line conductor, and storing in a memory information associating the first remote device with the first power line conductor.
