Abstract
System for tracking or identifying the phase designation, and/or measuring the phase angle or the power angle of electrical conductors at a remote location relative to a reference location, by measuring a time delay between an external clock source such as GPS and a zero crossing or other specified part of the waveform, associating a 'time tag' with each measurement, transmitting the time tags and measurement values over a bi-directional link between a field unit and a reference unit, and calculating and displaying a relative phase angle and/or a phase designation. The system finds application, for example, in identifying the phase of conductors, and optionally comparing their phase angle and/or their power angle, before making connections between conductors in a multi-phase electrical power distribution system.
