Evaluation of Rail Potential and Stray Current With Dynamic Traction Networks in Multitrain Subway Systems

In multitrain subway systems, excessive rail potential and stray current (RP-SC) appear in the reflux system during the dynamic operations of an over voltage protection device (OVPD) and a drainage device (DD), which has not been clarified until now and has seriously affected the safe operation of the systems. To accurately evaluate RP-SC with dynamic traction networks, the equivalent method of the reflux system with mixed parameters is...
