Abstract
A device (1) for measuring the vertical and/or transverse movement of a contact wire (202) of an overhead line (200), having two emitters/receivers (2a, 2b) and a reflective plate (3) that are directed towards each other such that a light beam emitted by each emitter of the emitter/receiver (2a, 2b) is reflected on the reflective plate (3) and returns to the receiver of the emitter/receiver (2a, 2b). The emitters/receivers (2a, 2b) are mechanically fixed either to a fixed support (300) or to the contact wire (202) of the overhead line (200) of which the movement is to be measured, and the reflective plate (3) is mechanically fixed to the other of either the fixed support (300) or the contact wire (202). An analysis of the light beams received by the receivers (2a, 2b) after being reflected on the reflective plate (3) allows the vertical and/or transverse movement to be obtained.
