Thermal Scanning

Overhead catenaries can become overheated, expanding to such an extent that they almost touch the wagons. When overheated, the contact wire starts to expand, loses tension and starts to sag. In the worst case, it gets wound up around the locomotive’s pantograph. The train stops and the line is blocked. Repairing overhead lines takes time and one can only imagine the consequences on busy lines at rush hour.

Thermal imaging is the way to minimize unscheduled breakdowns of all electrical and mechanical equipment on the overhead line plant. Detecting the rise in temperature at an early stage can prevent costly failures and downtime.
