Abstract:
1. A method to identify a phase in a multi-phase electrical system, comprising: providing a detection device having at least one sensor operable to detect a waveform on a cable of a multi-phase electrical system and a control unit that generates a time reference, the time reference being timed according to the frequency of the waveform and in phase therewith, to store timed data, synchronized with a detected waveform; using the detection device to detect a first waveform on a cable belonging to a first phase of the multi-phase system, in a first position of the multi-phase electrical system; storing in the detection device timed data, synchronized with the first waveform; moving the detection device to a second position on a different point of the multi-phase electrical system; and in the second position, finding a cable belonging to the first phase by
