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.

A cable status management system for managing a wire-break progress of a cable used in a managed device is provided with a cable status management device having a cable status storage unit that stores a wire-break progress data indicating the wire-break progress in the cable, a device user-side data management device that belongs to a device user that uses the managed device, a device manufacturer terminal that belongs to a device manufacturer that manufactures the managed device, and a cable manufacturer terminal that belongs to a cable manufacturer that manufactures the cable. At least the device manufacturer terminal and the cable manufacturer terminal are configured to be accessible with the wire-break progress data stored in the cable status storage unit via a network.
