An effort to apply modern signal-processing techniques to the detection of arcs on a direct-current (DC) power line in an air vehicle is proposed. The Phase-I effort will concentrate on demonstrating the feasibility of a simple, inexpensive technique for detecting both series and parallel arcs in DC power lines that operate at pressures corresponding to a range of flight altitude between sea level and 100,000 ft (760 - 5 Torr pressures). This effort will also identify applications that are not being addressed by present arc-fault-circuit-breaker technologies. A Phase-II effort will include incorporation of the technique into operational hardware.
