Efficient maintenance of contact lines should be based on their actual conditions rather than the length of period in which they have been used. Therefore, we developed a device that detects deterioration of feeder. As this device requires manual operation, however, we have newly developed a prototype feeder inspection robot for hard-drawn aluminum stranded wires (300mm2). We tested it at RTRI and in the field and confirmed its effectiveness.
