INDUCTIVE COUPLING OF A DATA SIGNAL TO A POWER TRANSMISSION CABLE

摘要

An apparatus for enabling communication of a data signal via a power transmission cable (100). The apparatus comprises a first winding (225) for coupling the data via a conductor of the power transmission cable, and a second winding (235), inductively coupled to the first winding, for coupling the data signal via a data port (255). An apparatus for identifying one of a plurality of neutral wires (105) of a power line includes a receiver (902) for sensing a signal from a selected neutral wire of the power transmission cable and an indicator (905) of a magnitude of the signal.
