1. Electromagnetic compatibility in the railway sector
In the railway sector, the only aspect still being dealt with concerns low-frequency (f < 20 kHz) conducted electrical disturbances emitted by rolling stock to railway signalling circuits, since they are a threat to the safety of train movements.
The technological evolution of on-board equipment (proliferation of electronic equipment, increase in the di/dt and dv/dt of power semiconductors, etc.) has been accompanied by a correlative increase in the problems of high-frequency electromagnetic interference up to 1 GHz.
To avoid a critical situation, and to standardize practices, a Directive on Electromagnetic Compatibility (EMC) was adopted by the Council of the European Community in 1989, recognizing EMC as an important element in the design of equipment. The European Committee for Electrical Standardization (CENELEC) has drawn up EMC...
