The paper introduces the basic principle of reactance fault location method, analyzes the errors of reactance fault location method for double track electrified railways under direct feeding mode, with combination of the requirements of train operation organization and the regulations of fault emergency response process, analyzes the problems of reactance fault location method in practical application, with introduction of mutual inductance factors, calculates the correction formula for reactance fault location considering mutual inductance factor, and puts forward a modified scheme for reactance fault location method based on judging the operation mode of parallel or disconnected power supply. The modified scheme has been verified to be feasible to a certain extent through actual examples.
