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.

1-13. (canceled)
A method for identifying a phase in a multi-phase electrical system, including:
- transmitting, on a defined phase of a line of the system, a message with a known synchronization with respect to a phase voltage;
- receiving the message on an undefined phase of the line;
- obtaining information on the phase on which the message is received according to a phase displacement between a voltage on said undefined phase and the message received.
A device to determine a phase in a multi-phase electrical system comprising:
- a transmitter, with terminals for electrical connection to a phase of said multi-phase system, said transmitter functional to transmit a message by carrier waves on said phase and to synchronize transmission of the message with respect a phase voltage;
- a receiver, with terminals for electrical connection to a phase of said multiphase system, said receiver functional to receive said message and to determine a phase displacement between a phase voltage on the phase to which the receiver is coupled and the message received.
