Abstract: Power systems having a DC content, such as photovoltaic (solar) panels present a problem if an arc fault appears because of a small break in a cable. The present disclosure describes an arc fault detection system that captures data in segments, examines the frequency spectrum to remove ‘false arc’ signatures and interference from a power converter of the power system, and then examines the cleaned frequency spectrum for arc events.
