Analysis of Transformer Fault Characteristics Based on Vibration Signal
In this paper,the generation principle of the transformer vibration signal and Hilbert yellow transforma-tion are studied.Based on the fault characteristics of the transformer vibration signal based on the Hilbert yellow transformation,the marginal spectrum results show that the marginal spectrum of 200Hz,300Hz and 400Hz will change in different fault states.
