On‐load tap‐changer fault mode recognition based on the singular value of Hilbert energy spectrum time‐frequency matrix and spectrum entropy

Abstract To solve the difficulty of eigenvalue extraction of on‐load tap‐changer (OLTC) vibration signals, an eigenvalue extraction method of time‐frequency matrix based on Hilbert energy spectrum and spectral entropy is proposed in this study. By optimizing the Hilbert‐Huang transform (HHT) algorit...
