1. the deformation of transformer winding on-line monitoring method based on online frequency response method is characterized in that:

  • said method comprising the steps of;

    Step 1;

    generate swept-frequency signal, be loaded on Transformer Winding by power amplifier;

    Step 2;

    the low voltage signal of data collecting module collected after the second filter filtering, and be converted into digital signal;

    Step 3;

    data processing module carries out the frequency response conversion to described digital signal, and differentiates related coefficient according to the digital signal calculating transformer winding deformation of input, differentiates the deformation extent of Transformer Winding.
