AUTOMATIC PHASE IDENTIFICATION FOR ELECTRIC POWER DELIVERY LINES

The present disclosure describes phase detection systems and methods. One or more line mounted intelligent electronic devices (IEDs) measure voltage at various points of a power system. The measured voltage is timestamped with a reference signal and compared with a timestamped voltage at a location where a phase on each conductor of the power system is known. Pattern matching may be used to determine the phase at locations where the phase is unknown.
