Most trains in metropolitan areas operate from DC voltage, which is carried either by a third-rail along or between the running rails, or by a catenary system of wires over the trains.

Testing the current collectors used on these trains is therefore an important task and is typically undertaken when a new design is going to be put into use.

This interesting data acquisition application requires a combination of a video camera and physical measurement sensors, including voltage and current. Displacement sensors are often used as well, along with accelerometers for measuring vibration. In our whitepaper, you will learn more about how these components are put together to guarantee the highest reliability for trains. Download our whitepaper now!
