According to the fault diagnosis and positioning method of transformer,the transformer fault diagnosis technology based on Vibration Analysis method is discussed.The technique involves the principle of core and wind-ing vibration,and the influence of mechanical structural changes on frequency concentration and vibration stability.Through the mutual information method,the precise positioning of the fault position has been achieved.The ex-periment shows that the Vibration Analysis method can not only provide a comparable or better detection accuracy than the traditional method,but also has the advantages of non-invasive and real-time monitoring,which is an im-portant means of power system maintenance and fault prevention.
