The invention discloses a train and an electric leakage protection system and method thereof, and the system comprises an electric leakage detection unit which is used for detecting whether a high-voltage power supply line of the train leaks electricity or not in real time; the door controller is used for controlling opening and closing of doors of the train; the electric leakage processing unit is connected with the electric leakage detection unit and used for acquiring the voltage of the high-voltage power supply line in real time and controlling a high-voltage contactor on the high-voltage power supply line to be disconnected when the electric leakage detection unit detects electric leakage of the high-voltage power supply line; and the whole vehicle control unit is connected with the electric leakage detection unit, the electric leakage processing unit and the door controller, and is used for controlling the door controller to open the door of the train when the electric leakage detection unit detects that the high-voltage power supply line does not leak electricity any more and the voltage of the high-voltage power supply line is smaller than or equal to the preset safety voltage. According to the train and the electric leakage protection system and method thereof, the safety of passengers can be effectively guaranteed when the train leaks electricity.
