ABSTRACT:
A system detects the wiring phase of an unknown phase voltage at a remote location relative to a reference phase voltage at a reference location in an electrical power distribution system having a single phase or poly phase power line. A transmitter transmits a signal from the reference location to the remote location. The signal comprises a characteristic signal pattern. Moreover, a first circuit detects at the remote location the characteristic signal pattern of the signal and determines a first time interval between the characteristic signal pattern and the occurrence of a reference point in the unknown phase voltage. A second circuit determines at the reference location a second time interval between the characteristic signal pattern and the occurrence of a reference point in the reference phase voltage. The system determines the wiring phase of the unknown phase voltage from the first time interval and the second time interval.
