Abstract: |
Based on analyzing the fault characteristics of the asynchronous motors and using symmetrical components method an algorithm of time difference and shifting phasor is adopted to detect intelligently the current amplitude of positive,negative and zero sequence currents.With the proposed method,automatic diagnosis of most common faults for medium and small sized asynchronous motors can be realized.This method will have vast application prospect. |
