1. A method for detecting a fault in an electric power distribution network comprising:

  • continuously receiving, at a power line communications (“

    PLC”

    ) receiver, electric power line signals from the power network;

    processing the received power line signals to obtain signal data representative of physical characteristics of the received power line signals; and

    performing fault evaluation processing using the signal data and at least one of predetermined fault signature, high frequency, signal harmonics and network topology data to determine whether the signal data corresponds to an existing or anticipated fault in the power network.
