| Abstract: | Based on the analysis of the mechanism of exploring coil detecting turn-to-turn short circuit of rotor winding,fault diagnosis system is designed.Based on WTMM,the signal is analyzed and the Lipschitz index of wave characteristics is calculated.With MATLAB as the background to simulate the signals and the variance of Lipschitz index as calibration,the fault location and degree of the turn-to-turn short circuit can be determined.The experiment shows that determining the fault and the fault degree by means of... |
