Transformer Winding Deformation Tester

Transformer Winding Deformation Tester is used for power transformer with voltage grade of 6kV and above and other transformers with special purpose.

Product Description

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.
