EMC Analysis of Axle Counters in the Italian Railway Network

The need of transport interoperability in Europe is a relevant issue nowadays. Particular interest is given to the signaling systems. The TEN-T project focuses one of its workpackages on “EMC Axle Counter Validation.” This work developed in the frame of the TEN-T project develops a procedure to assess the frequency spectrum of the magnitude of the magnetic field, due to the traction current, at the track level. Full-wave 3-D numerical models are developed to predict the field values. The measuring system is previously tested and then used for a measurement campaign. Results are reported in terms of tables and frequency spectra.
