Abstract
A fault protection system for an AC-DC distribution system detects the presence of DC content at individual loads, isolates the load responsible for the fault from the remainder of the distribution system, and blocks DC content from being propagated from the faulty load to the AC source. The fault protection system includes at least one circuit breaker connected to monitor the AC current provided to the individual electrical load and to detect the presence of DC content indicative of the load being faulty. In response to detected DC content, the circuit breaker trips open to disconnect the electrical load from the AC distribution system to prevent DC content from being propagated to adjacent loads.
