VMD-Assisted DGCM-Net: A Dual-Representation Cross-Interaction Network with Multi-SNR Training for Transformer Core Looseness Diagnosis

Vibration-based diagnosis can identify transformer core looseness non-intrusively, but subtle vibration differences and noise-disturbed Gramian angular field (GAF) textures reduce diagnostic accuracy at low signal-to-noise ratios (SNRs). This paper proposes a variational mode dec...
