    Abstract: A power line communication and real-time wiring fault location system includes a power distribution system, a plurality of solid-state power controllers, and a communication and fault location determination circuit. The power distribution system includes an upstream power feeder line and a plurality of load-end feeder lines. Each solid-state power controller is associated with a different one of the load-end feeder lines and is configured to selectively couple its associated load-end feeder line to the upstream power feeder line and detect an electrical fault on its associated load-end feeder line or in an electrical load to which the associated load-end feeder line is coupled. The communication and fault location determination circuit is coupled to each of the load-end feeder lines and is configured, in response to a channel selection command, to selectively transmit a fault location stimulation signal onto one of the load-end feeder lines.

    Abstract: A solid state power controller (SSPC) for an electrical power distribution system (EPDS), the SSPC may include a solid state switching device (SSSD) configured to interrupt current in a feeder line of the EPDS and a processing engine. A clamping device may be interposed between the feeder line and an electrical ground of the EPDS, An opto-coupler may be interposed between the processing engine and the clamping device. The opto-coupler may coupled to the clamping device to provide a lightning-detected signal to the processing engine only when a voltage drop develops across the clamping device. The processing engine may be constrained from commanding an alteration of state of the SSSD upon receiving the lightning-detected signal.
