flashover
flashover[′flash‚ō·vər] (electricity) An electric discharge around or over the surface of an insulator. (engineering) A condition occurring during a fire in a building in which the surfaces of everything within a compartment or room seem to burst into flame simultaneously. flashoverA fault in a reciprocating engine's ignition system. The high voltage in the magneto distributor jumps to the wrong terminal, resulting in the wrong spark plug firing with a consequent loss in power. Flashover can happen because of moisture in the distributor. It can also occur when an aircraft is flying at high altitudes and the air inside the distributor does not have sufficient density to be an effective dielectric.flashover
