Abstract
In order to detect abnormality of a cable, the cable has an electrical conduction line surrounding a power supply line, an electric potential of the electrical conduction line is controlled by a controller, and the abnormality of the cable is judged by detecting the inability of the controller not to control the electric potential of the electrical conduction line in case of contact by the electrical conduction line with the ground or the power supply line. Damage to the power supply line from the accident is prevented by previously detecting the accident of the cable, thereby, the reliability of the cable is highly improved.
