Abstract
A method for transmission of information, received at a transmitter of a power distribution system, over at least one conductor of that distribution system, requires the reception, at the transmitter, also of at least one PLC signal at a power-line communications (PLC) frequency and from an associated first conductor portion of the system. The transmitter processes the local data signal and the PLC signal to generate another PLC signal, also at the PLC frequency, which is coupled through the non-saturating core of a transmitter-coupling current transformer to inject a PLC current into a second conductor portion of the system. The PLC signal is eventually received by a receiver, connected to a system conductor at a location different from the location of the transmitter, and the transmitted information is recovered therefrom.
