Automatic measurement of overhead power line joints

A new design and construction of a remotely controlled vehicle is described which features a two-wheeled vehicle moving along the double overhead power line cables to detect the position of the compression typed mid-span-joint relative to the aluminium sleeve. The mechanical design and construction of an unmanned motor-driven automatic measurement vehicle, detection units covered a number of different functional sensors and control system including various control methods involved in this project will be described and also results obtained from a number of tests will be presented.
