Abstract
Placed in electrical circuit in shunt of the electrodes that supply current to a protected device and optically coupled to the location in the protected device where an electric arc is most likely to occur, a photosensitive device, responsive to illumination created by such an electric arc, switches to a conductive state, thereby short circuiting the electrodes feeding current to the arc and the arc is quickly extinguished.
