In this paper, the main conductive and radiative electromagnetic sources are introduced especially for low frequency electromagnetic sources. Systematic and equipment view of electromagnetic field in the normal operation are simulated and analyzed by Maxwell and HFSS based on FEM. This paper provides an overview of the low frequency conductive and radiative EMI and EMC for the high speed railway.
Current passing through conductor in free space of air generates magnetic field which could interfere with the other apparatus nearby or even interrupt it. Inversely, the electromagnetic sources could also be affected by reaction filed or field generated from else. Therefore, the equipment needs to be designed to both blocking and tolerating the electromagnetic radiation. The electromagnetic interference...
The paper presents the investigation of the electromagnetic interference for the traction system in a high speed railway (HSR). Tt is important to study the characteristic of the transformer, converter and power cable for HSR. Traction transformer as the one of the first equipment on board traction system for connection to pantograph, and plays a key role in the electromagnetic investigation. In this...
