MEASURING DEVICE FOR SLIDING SURFACE WIDTH OF TWO CONTACT WIRES

Inspection of trolley wire is of growing importance as electrification spreads on the Japanese National Railways. A measuring device for the sliding surface width of the contact wire, developed in 1971, has proved to have an accuracy of 0.1 mm at 210 kph. The device consists of a camera, mirrors, flood lights, servo mechanism and control panel. Results of tests with this system are given.
