Abstract: A system and apparatus for detecting and locating an arc fault in a photovoltaic solar power array. A plurality of capacitors divide strings of photovoltaic cells into a series of magnetic loops. When an arc fault occurs within one of the loops, a time-varying magnetic field is produced, with flux lines emanating from the area enclosed by the loop. At least three magnetic field sensors arranged at locations in or around the solar power array detect the spectral signature of the arc fault, and send related data to a computer via a communication network. The computer analyzes the data from the sensors to determine the location of the arc fault.
