Experimental and simulated test results demonstrate the effectiveness of the proposed technique, which is based on the spectral analysis of the AC component of the on-load exciting current Park's Vector modulus.application/pdfporMáquinas eléctricasTransformadores621.313TransformersWinding faultsDiagnosticsExtended Park's vector approachjournal article
