<p>The invention relates to a device that can compensate at the point of origin disturbances of the magnetic field in the surroundings of a railway line caused by fluctuations in the current of the power supply catenary. Said system aims at creating a return circuit whose geometry varies depending on the position of the train and which suppresses at the point of origin the field produced by the catenary-train-track and reduces disturbances in the magnetic field in the surroundings. The system is based on deriving the return current from the track that is divided into elementary segments isolated from one another to a return conductor located adjacent and parallel to the catenary by means of a series of vertical conductors connecting each segment to the return conductor.</p> |
