Self-powered apparatus and method for optically detecting arcing faults in electric power systems in the presence of other light sources

Arcing faults in an electric power system are detected by sensors (1, 1') powered by the light generated by the arcing even in the presence of background light. The sensors (1, 1') have one or more first photovoltaic cells (5) energized by light passed through a first filter (7) having a p...
