Paper Abstract
For the Netherlands railway company a system for inspection of the degree of wear of the contact wires is being developed. With an active sensor the reflective under-surface of the overhead wire is illuminated with a laserbeam and reflected radiation is detected by fast CCD detectors. With the sensor at a train speed of 90 km/hr. every cm of max. 4 overhead wires will be inspected, determining the wire thickness and the appearance of holes caused by local sparks. For illumination and detection a special optical system has been developed. From the railway inspection waggon measurements have been performed with a prototype system, demonstrating the feasibility of the measuring principe.
