<p>There is provided a method for protecting loads associated with power distribution system inductive signal couplers. The method includes (a) providing an inductive signal coupler (110) having a first winding (105) in series with a line conductor of a power distribution system, and a second winding (115) having first and second connection terminals (120, 125) (b) connecting a first terminal of a first fuse to the first connection terminal, and a first terminal of a second fuse to the second connection terminal, a second terminal of each fuse being connected to a communication device, and (c) connecting a first terminal of a first choke (140) to the second terminal of the first fuse (130), and a first terminal of a second choke (145) to the second of the second fuse (135), a second terminal of each choke being connected to an electrical ground.</p> |
