Comprehensive Diagnosis Method of Winding Deformation of Power Transformer
摘要
Abstract
To improve the diagnosis accuracy of winding deformation in power transformer, the integration of frequency response analysis (FRA) method, short-circuit impedance and winding capacitance measurement were discussed and used for identification of transformer windings. The accuracy of dynamic integration of three methods is proved through the comparison of the theoretical analysis and calculation with the disassemble results of the fault power transformer.关键词
