The return current earthing system has important safety significance in electrified railways. In order to clarify the differences in standards of return current earthing of China and Europe, and promote the internationalization of standards of China, the paper compares and studies the safety earthing design and low-voltage equipment protection standards for return current earthing of AC traction current for railways of China and Europe. After summarizing and comparing, it can be concluded that the basic principles of the return current earthing system remain consistent, but there are differences in technical details. Finally, it is recommended to conduct in-depth research on the return current earthing system in accordance with China's national conditions to improve and optimize the related standards, and actively participate in the internationalization of the standards.
