Abstract
Methods to determine the location of an arc fault include a first method utilizing the inherent resistance per unit length of the wire. A second and a third method utilize an inherent inductance per unit length of the wire. The second method derives the inherent inductance from the output voltage and a rate of current rise. The third method derives the inherent inductance from a resonant frequency of an oscillating current. The information is useful to locate a fault emanating from a wire member of a wiring harness used to distribute power about an aircraft.
