Transversal Defect Detection System - TDDS

Based on high resolution digital cameras and high power illumination modules, TDDS acquires high resolution images of cantilevers, line hangers and insulators, residing in the transversal plane, and evaluates changes and/or corrosion in these objects.

Through a double sided imaging process, triggered by the Pole Detection System, images are acquired on both sides of the cantilever infrastructure to detect:

• Changes on main catenary infrastructure devices
• Detection of broken or deformed parts on cantilever devices
• Detection of broken or missing parts

Each defect is associated automatically to the kilometer/mile position on the track and the related image is saved in a file for further evaluation by the technicians.
