A non-contact vibration detection and partial discharge fault diagnosis method for high-voltage switchgear

To address the early concealment of partial discharge (PD) defects in high-voltage switchgear and the difficulty of external non-contact identification, this paper proposes a PD defect identification method based on laser Doppler vibrometry and vibration signal analysis. A KYN28-12 high-voltage switchgear cabinet is ta...
