Abstract
A method and system are given for a coupling a data signal over a power distribution system. An inductive signal coupler has two windings. The first winding is in series with a line conductor of the power distribution system. A capacitor is connected between the first line conductor and a second line conductor of the distribution system such that the capacitor presents a high impedance to a power signal and a low impedance to a data signal. A communication device is connected to the second winding so that a data signal can be coupled between the communication device and the distribution system.
