| Abstract: | The voltage and current of the catenary in electric traction section will affect the signal cables because of the continuous distribution of the alternating electromagnetic field generated in its surrounding area. By combining with practical engineering cases, this article introduces the measurement and protection measures to the influence on magnetic induction of the signal cables from the catenary with direct power supply. |
