Lightning Overvoltage Protection Technologies for High‐Speed Railway Traction Power Supply Systems: Current Status and Future Prospects

High Voltage, EarlyView.
ABSTRACT The traction power supply system of high‐speed railways is exposed to complex lightning environments over the long term. Overvoltage generated by direct lightning or induced lightning can propagate along the overhead contact line, traction substations, onboard high‐voltage system and mobile grounding system, thereby threatening equipment ...
