Transformer Winding Deformation Tester is used for power transformer with voltage grade of 6kV and above and other transformers with special purpose.
The power transformer is inevitably vulnerable to impulse of various fault short-circuit current or physical collision
in the process of operation, transportation and the transformer windings may lose stability under the powerful electro-dynamic force
exerted by such short – circuit current, which could result in permanent deformations such as local distortion, swell or dislocation
and will severely affect safe operation of the transformer.
Transformer Winding Deformation Tester
Deformation of transformer windings is measured with frequency response analysis method according to national standard
DL/ T911-2004 for electric power industry, i.e. detect amplitude-frequency response characteristic of each transformer winding and
make vertical or horizontal comparison of the detection
result to judge possible deformation of the transformer winding based on change of amplitude-frequency response characteristics.
