Product Description

I Description

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.

II Main features

l  Two checking methods, up-to-date technology

l  No need to do any disassemblies for test, except for removing connecting busbar.

l  Split style structure, connection between main instrument and computer can be via USB or Ethernet network, plug and play.

l  All connectors have fault tolerance, site connection is safe and simple

l  High intelligence level, equipped with self-adapting filter, automatic range adjusting, automatic sampling frequency adjusting.

l  Adopts high speed high precision AD converter, good testing stability and repeatability, high testing accuracy, better than 0.1%

l  Equipped with expert diagnosing system, automatic diagnose winding conditions

III Specialty of testing software

l  Adopts windows platform, compatible win9X/windows2000/winXP

l  Loading 6 curves simultaneously, automatically calculate parameters of every curve, automatically diagnose deformation condition and provide conclusion for reference.

l  Strong software managing function, automatically save ambient condition parameters, providing basis for diagnosing winding deformation; automatically saving testing data, color printing test reports.

l  Humanistic software providing options for different conditions, no need many site inputs, convenient operation.

l  High intelligent software, press one key to finish all the test works
