Track Conductivity

Avoiding power losses, reducing corrosion due to non-railway underground equipment near the track, and ensuring proper track insulation.

Tests objectives

  • Check without “mechanically” cutting the track that it does not generate stray currents
  • Monitor compliance of track insulation during commissioning or preventive maintenance.

Tests facilities

  • Dedicated power supply
  • Voltmeters and ammeters
  • Data acquisition and processing system

Testing norms

EN 50122-1 et -2 – Fixed installations – Electrical safety, earthing and the return circuit – Part 2: Provisions against the effects of stray currents caused by DC traction systems
