The necessity to detect the electrodes' crack of the electric power locomotive is discussed in this paper. According to the testing particularity of the electrodes, the crack is detected effectively through using send-receive eddy current testing method. Moreover, the principle of developing a complete eddy current testing system and its constitute of software and hardware are emphatically introduced. The experiment results show this testing system can detect the electrodes' crack of the electric power locomotive accurately and effectively, and its testing interface is friendly?practical and effective.
