Abstract
The invention relates to a system for measuring the position of the contact wire of an overhead power line, comprising a first measurement means including a vertical rangefinder capable of measuring the height of the contact wire and a second measurement means capable of measuring the offset of the contact wire. The system also comprises at least one first inclinometer that enables the inclination of the mounting of the system positioned on the rails to be measured, and a camera pointing upward and capable of capturing the image of the contact wire, and the second measurement means comprises a second inclinometer secured to the laser rangefinder, which is mounted on a motor-driven lateral-inclination pivot, and which is capable of measuring the angle of the beam thereof relative to the vertical when aimed at the contact wire.
