Abstract :
The 25 kV AC 50 Hz electrification systems have been developed specifically for railway traction purposes. The main feature that separates this system from the conventional 3 phase and neutral HV distribution network of the public supply authority is that the railway system is a single-phase system with one pole intentionally earthed. Even though railway administration have their own individual electrification schemes the basic design of the systems are the same.
