Abstract

Wire on-line detection technology is significant to aircraft wire fault diagnosis. Spread Spectral Time Domain Reflectometry (SSTDR), which is an effective method for wire fault detection on-line, is studied and analyzed in this paper for aviation field. Simulation platform and experimental system with FPGA as the core are established. Based on test results, this method is verified to be effective on real-time detection of wire carrying 115V/400HZ AC power signal. Through the analysis of theory and experiments, its detection accuracy and application field are obtained.
