Mechanical fault diagnosis of on‐load tap‐changer based on improved variational mode decomposition and relative density‐based outlier score

Abstract In order to diagnose the mechanical fault of transformer on‐load tap‐changer (OLTC) effectively, a fault diagnosis method based on improved variational mode decomposition (VMD) and relative density‐based outlier score (RDOS) is proposed. Firstly, the signal is decomposed into a series of mo...
