Stray Current Monitoring System on Shenzhen Metro Line 3

By analyzing the causes and hazards of stray current, this paper proposes the data of monitoring and points out its importance. A set of stray current monitoring system was designed in accordance with the requirements for monitoring the stray current in Shenzhen subway. The system follows the centralized distributional monitoring principle and consists of reference electrode, road network test bed collection terminal, elevated bridge collection terminal network testing, collection network terminal tunnel testing, smart sensor, communication cable, data (communication) adapter unit and PC management system,etc. The system also transmits the data to the PC and realizes the function of the real-time monitor.
