Rolling stock electromagnetic compatibility

Checking that electrical signals generated by the train are compatible with the signalling, telecommunications, sub-stations and overhead lines for type approval purposes.

Objectives

  • Carry out dynamic tests, on trains or at standstill, during development or qualification of trains or components
  • Establishing real time the current
    – Generated by rolling stock
    – That can interfere with signalling
  • Determine psophometric intensity
  • Ensure coordination between traction units and fixed installations used for electric traction: power factor, power consumption, inrush current, peak voltage value, etc.
  • Measure the effects of pollution of a brake shoe or material on a sample of wheel steel
