Selection Criteria of Test Signals for Correlation-Based Wire Fault Analysis (Preprint)

Abstract

This paper compares reflectometry signals for location of intermittent faults on live electrical cables. STDR, SSTDR, linear chirp, quadratic chirp, concave-up chirp, convex-down chirp and all frequency randomized phase noise signals were tested. The SSTDR was observed to be the most effective signal for live wire testing, because of its minimal interference with the existing signals and narrow correlation signature. This paper provides a methodology for systematically evaluating signal performance and design criteria for live wire test systems.
