A Study on L.V.I. Diagnosis Field Application of Transformer Winding Deformation

변압기 권선변형 L.V.I. 진단 실적용을 위한 연구

We describe the possibility of field application and the diagnosis method of winding deformation in the power transformers using L.V.I. test system. Any winding deformation will result in a change of capacitance between winding parts and passibly some change in the winding inductance. These changes will then result in a change in the responce to the applied pulse in both the magnitude and period of the resulting oscillations. And we discuss with respect to test result of model transformer and commercial transformer, appear good results with application possibility in field.
