Electromagnetic compatibility of rail transit product test items and common standards

At present, the development of urban rail transit has shown a diversified trend, especially the construction of intercity rail transit lines and suburban lines is increasing, with multiple forms of large, medium, and suburban lines coexisting, and the development of rail transit is diversified. Properly handling electromagnetic compatibility issues related to rail transit power supply systems can enable various electrical equipment and systems to coexist harmoniously and not disturb each other. It is not only a prerequisite for ensuring the safe and reliable operation of urban rail transit, but also an important measure to ensure the personal safety of the people.
