Abstract
A method for detecting a disconnection of a conductor of a cable includes performing an excitation to apply a periodic vibration at an arbitrary examined portion in a longitudinal direction of the cable, measuring a time-series resistance value of the conductor by the excitation, performing a frequency analysis for the measured time-series resistance value of the conductor, extracting a resistance value variation component at an exciting frequency corresponding to an operation period of the excitation from a result of the frequency analysis, and detecting the disconnection in the conductor at the examined portion based on a magnitude of the extracted resistance value variation component.
