Abstract :
This paper built a model of tractive power supply system, analysed the influence on signal cables due to tractive power supply system through the software ATP-EMTP and found out influencing factors of the induced voltage in signal cable core of railway system. Simulation shows that: Structure and size of signal cable, earthing methods and earth resistance of the signal cable sheath are three of the most important factors. There are several ways to reduce the induced voltage in signal cable core, such as reduce the earth resistance of cable sheath and increase the number of earthing contacts of cable sheath.
