ABSTRACT:
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 having a first winding in series with a line conductor of a power distribution system, a second winding having a terminal, and a magnetic core for coupling a signal between the first winding and the second winding, (b) situating a layer of electrical insulation between the second winding and the magnetic core, and (c) connecting the terminal to an electrical ground so that a voltage between the magnetic core and the electrical ground is placed across the layer of electrical insulation. There is also provided an inductive signal coupler having (a) a winding in series with a line conductor of a power distribution system, and (b) a conductive plate at an end of the coupler distal from the first winding, for routing a flashover current to an electrical ground.
