Arc tracking
Arc tracking : Arc tracking is a phenomenon in which a conductive carbon path is formed across an insulating surface. The carbon path provides a short circuit path through which current can flow (e.g., electrical arcing.) Circuit breakers are especially susceptible to Arc Tracking. The effects of electrical faults can include: (1) Component overheating. (2) Toxic fumes. (3) Smoke. (4) Fire. (5) Damage to wires, wire bundles, or parts. (6) Melting of holes in sheet metal parts by faulted, high current feeder cables. (7) Melting and burning of titanium bleed air ducts by a chaffed, high current feeder cable. (8) Electromagnetic interference (EMI) with equipment. (9) The simultaneous and unreasonable loss of both engine driven generators in a two engine airplane
