The catenaries are a critical part of railway infrastructure because they provide the train with electricity. When there is an incident on such a critical equipment, traffic is interrupted for hours. Much of these incidents are caused by low mechanical tension. Temperature changes and frost are the leading reason of failures. Regularly, maintenance agents plan tightening interventions on the cable.
INTESENS has developed a sensor to monitor cables’ mechanical tension. Multiple sensors are installed over several kilometres to follow the cable tension in real time during the maintenance operations. It offers substantial benefits for agents by reducing the length of the intervention and facilitate the coordination between teams. Once the installation is completed, some of the sensors are kept on site and agents can monitor the cable tension evolution over time and plan the interventions much better.
