Abstract
A system and method for dead-line conductor phase identification is provided. The system includes a receiver unit having a set of current sensors, such as current transformers. The receiver unit current sensors are coupled to conductors having a known phase in a multiphase power line. The current sensors are positioned adjacent a transformer connected to a section of the power line having an open circuit condition. A transmitter unit transmits a current signal on to a conductor at the open circuit section of the power line. The current sensors detect the current signal and the receiver unit transmits a signal to the transmitter unit identifying the phase on which the current signal was transmitted.
