This paper reports an experimental procedure for the characterization of the static magnetic field generated by large inductors installed in 50 Hz resonant filters, which are used for the reduction of electromagnetic interference induced in the Italian 3 kV dc railway infrastructure by nearby 25 kHz -50 Hz high-speed railway lines. The procedure and the related measurement system represent an effective tool to characterize dc magnetic-field levels in the railway environment in order to assess compliance with ICNIRP guidelines on human exposure to static magnetic fields.
