Research abstract

Within Phase 2, Williams-Pyro has designed, developed, and demonstrated a system for locating arc faults along aircraft cable. This fault localization is performed using signal reflectometry, in which an electrical waveform is transmitted through a length of wire. After the reflection is received, the characteristics of the reflected signal will be used to determine how far away the arc fault is located. After miniaturizing this system, it will be possible to integrate this functionality within a Texas Instruments' arc fault circuit breaker. In this manner, TI's AFCB's will be able to tell maintenance personnel where to look in order to perform repairs on the aircraft cable
