Explore the application architecture, understand the critical measurement points and connect each function to the appropriate ADISENS sensor family.
Railway electrification links a fixed traction-power infrastructure to moving rolling stock. Depending on the network, electrical energy is delivered through an overhead line or third rail, conditioned by traction substations, then converted onboard for propulsion and auxiliary loads.
The sensing chain is therefore distributed. Trackside equipment needs current and voltage feedback for feeder supervision, protection and converter control, while the vehicle needs fast, isolated measurement around high-voltage inputs, traction converters, motors and auxiliary systems.
The schematic below separates infrastructure sensing from onboard sensing and links each measurement point to the relevant ADISENS family.

Current and voltage measurement are required inside traction-power equipment for feeder supervision, converter regulation, protection and diagnostics.
The onboard chain combines high current, high voltage, switching transients, vibration and railway-specific qualification requirements.
Reference-level selection depends on nominal range, overload, output, mechanical integration and qualification status.
