Abstract

There is provided an inductive coupler for coupling signal to a power line (800). The inductive coupler includes a magnetic core (810, 811, 812, 813) for placement about the power line (800), a coil (820) wound about a portion of the magnetic core (810, 811, 812, 813), and a semiconducting coating (905) that encapsulates the core (810, 811, 812, 813) and contacts the power line (800). The signal is coupled to the coil (820).
