Abstract: Wiring system is usually installed in manufacturing facilities to construct a data network. During the operation of the manufacturing facility, environmental and operational stress conditions may degrade material properties of the wires, and cause wire faults and failures, which deteriorate the electrical connection within and out of the wiring system. Conventional health monitoring approaches, such as time domain reflectometry, have been actively developed to detect wire faults with improved accuracy. However, these approaches often require external devices connected with the wiring system, which may interfere system operation, and lead to inevitable system downtime of the facility for maintenance. In order to eliminate unnecessary system downtime, alternative means for wiring health monitoring is required.
