Abstract The level of high-speed railway electrical traction power is very high, and so is the short circuit current, so the short circuit fault happened the thermal stability of traction transformer is more easily to damage. The current protection scheme of traction transformer can not meet the needs of security and stability completely. In this paper the inverse time overcurrent protection act as the backup protection of traction transformer, coordinated with the main protection and other backup protection. Making a study on its application circumstances, and proposing the protection scheme of inverse time overcurrent protection.
