Product Description

Transformer winding deformation tester


  • Transformer winding deformation tester is for checking deformation conditions of high voltage transformers.
  • It adopts two methods to checking deformation conditions: scan-frequency method and low-voltage impedance method.

Main features

  • Two checking methods, up-to-date technology
  • No need to do any disassemblies for test, except for removing connecting busbar.
  • Split style structure, connection between main instrument and computer can be via USB or Ethernet network, plug and play.
  • All connectors have fault tolerance, site connection is safe and simple
  • High intelligence level, equipped with self-adapting filter, automatic range adjusting, automatic sampling frequency adjusting.
  • Adopts high speed high precision AD converter, good testing stability and repeatability, high testing accuracy, better than 0.1%
  • Equipped with expert diagnosing system, automatic diagnose winding conditions

Specialty of testing software

  • Adopts windows platform, compatible win9X/windows2000/winXP
  • Loading 6 curves simultaneously, automatically calculate parameters of every curve, automatically diagnose deformation condition and provide conclusion for reference.
  • Strong software managing function, automatically save ambient condition parameters, providing basis for diagnosing winding deformation; automatically saving testing data, color printing test reports.
  • Humanistic software providing options for different conditions, no need many site inputs, convenient operation.
  • High intelligent software, press one key to finish all the test works
