Analysis and suppression of operational overvoltage and inrush current for high‐speed trains by automatic phase‐switching technique

High Voltage
When a high‐speed train approaches the insulated phase‐splitting section embedded between neighbouring power supply arms, the vacuum circuit breaker (VCB) installed on trains must be disconnected to maintain the traction power supply system as a no‐load ...
