Abstract
To identify a phase in a multi-phase electrical system, the following method is proposed: transmission, on a defined phase (L1, L2, L3) of a line of the system, of a message with a known synchronization with respect to the phase voltage (V1, V2, V3); reception of the message on an undefined phase (X, Y, Z) of the line; identification of the phase on which the message has been received according to the displacement between the voltage on said undefined phase and the message received.
