Improved empirical wavelet transform (EWT) and its application in non-stationary vibration signal of transformer
Abstract The resonant frequency of the transformer contains information related to its structure. It is easier to identify the resonance frequency in the vibration signal during the hammer test and power on than in the operation of the transformer, because the vibration caused by the load current do...
