In order to solve the problem that it is difficult to detect the weak sinusoidal response signal when the frequency response method is used to detect the transformer winding deformation fault online, this paper proposes a method to detect the amplitude of the response signal by using Duffing oscillator. Secondly, in order to solve the influence of the target signal phase shift on the amplitude det...Show More
Aiming at the problem that the current frequency response method still lacks an effective tool for consistent quantitative evaluation in data analysis, and the correlation coefficient method cannot judge the deformation of the transformer winding when the measured frequency response curve is the same as the reference frequency response curve with the different amplitude, this paper proposed a new ...Show More
