About Transformer winding deformation tester
Transformer winding deformation tester
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.
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
