Continuous gauging of electric traction contact wire

In this system the electric traction overhead contact wire wear is continuously measured. A GaAs LED and lens combination produces a collimated beam of light along the pantograph pan. The beam, through which the contact wire slides, is monitored by a vertical array of phototransistors spaced at equal intervals. The number of phototransistors in shadow at any instant is proportional to the contact wire thickness. A fibre-optic data link conveys the encoded information from the pan at high tension to the locomotive at ground potential.
