Product overview:

Transformer winding deformation testing (frequency response method) for testing 6KV And above voltage class of power transformers and other special-purpose transformers, power transformers in operation or during transport will inevitably suffer a variety of fault short-circuit current of shocks or physical impact, in the presence of strong electric short-circuit current transformer winding may lose stability, leads to distorted drum kit or permanent deformation phenomena such as displacement, which will seriously affect the safe operation of the transformer. According to the State electricity industry standards DL/T911- 2004Measurement of transformer winding deformation by frequency response analysis, through the detection of amplitude-frequency response characteristics of transformer windings, and the test results are vertical or horizontal comparison, according to the variability in the amplitude-frequency response characteristics, judge transformer winding deformation that may occur.

Transformer winding deformation testing (frequency response method) measurement and analysis of software components, measuring part is composed of signal generation and signal measurement of black boxes, analysis by the notebook computer, measuring part USB Or networks connected to the laptop.
