Summary:Before cables can be replaced in power plants, they must be properly identified. We have developed a new cable identification method that does not need contact with the conductor of the cable before replacement. The method uses two techniques. The first is based on inductive coupling by a high-frequency search signal that is injected into the cable. The second is based on the change in the cable signal propagation characteristic, which occurs by applying or by removing a magnetic core on the cable. We carried out an experiment in an environment like that of actual cable laying conditions to confirm the effectiveness of our developed method and found that the cables could be identified accurately.
