Leakage inductance parameter identification method and the application of transformer impedance circle characteristics in transformer winding deformation detection are introduced. By using Qt, which is a cross-platform graphical interface development tool, the transformer winding deformation evaluation software is designed on the basis of fault recorded data. This software has realized the functions of recorded data reading, waveform drawing, leakage inductance parameter identification based on the least square method, the elliptical eccentricity identification of impedance circle characteristics and comprehensive assessment of transformer winding status. The software has clear interface and powerful functions, and obtains good effects in practical application.
