Arcing in high voltage DC circuits can lead torncatastrophic failures in air vehicles. Detection andrnmitigation of DC arcing in series is especially difficult.rnSince DC arcing is more severe than AC or "TickingrnArcs" the use of BIFURCATED ARC FAULTrnDETECTION (BiFAD) will lead to a new and Novelrnmethod of detection of both parallel and series arcing inrnelectrical power distribution systems. In unmannedrnCombat Vehicles, system survivability and redundancyrnare essential. The ability to overcome a single arcingrnfault and re-apply power without restarting the arc eventrnis a design priority. The removal of hydraulic andrnpneumatic power systems in Unmanned Air CombatrnVehicles (UCAV’s) will reduce maintenance andrncomplexity. Bifurcated circuits will provide the ability tornreroute power systems to compensate for battle damagernor distribution systems failures. This should lead tornimproved mission completion rates and allow safernrecovery of indispensable assets. This method isrnapplicable to both AC and DC circuits, Since the currentrnaerospace AFCI devices are adequate for most of thernTicking arcs, and this wiring method is not suitable forrndirect replacement or retrofit of existing circuit protectionrndevices, this paper will deal with a new method ofrnelectrical distribution in future all electric aircraft.
