Based on the autotransformer split winding fault simulation test platform the overall frequency response of the split winding and the frequency response of each independent winding are tested under fault free and typical fault conditions and the electrical parameters are simulated and analysed so as to study the characteristics of the frequency response and its change
Vibration analysis is a widely used method for power transformer fault detection Through measuring the vibration signal on the surface of the transformer tank and extracting the eigenvalues internal mechanical faults can be diagnosed However due to the insufficient fault samples and it is difficult to decouple the vibration of core and winding extracting the vibration
