Transformer Winding Deformation Tester

Type: ZC-206
       The transformer tester winding deformation tester quantifies the variation of the winding parameters in different frequency domains, determines the degree of deformation of the winding according to the trend of variation, range, range and frequency response, and then judges whether the transformer is seriously damaged or needs according to the test result. Overhaul. The device is compact and easy to operate.

Product Features
    1. The transformer tester uses a high speed, highly integrated microprocessor for sampling and control.
    2. This transformer tester uses USB to connect laptops and devices
    3. Use wireless blue-tooth interface to communicate the notebook PC and device. The high-speed microprocessor integrated with device, need not move the computer during the field test.
    4. Hardware cassette mechanism adopts DDS (from America), can correctly detect the breakdown :distortion, swell, shift, tilt, inter-turn short circuit deformation and contacting short circuit inter-phase.
    5. High resolution dB to test, dual channel, 16 bit A/D sampling (the wave from curve will change obviously if change the tapping switch during the field tests. )
    6. The software can adjust the output signal range, the maximum amplitude peak±10V.
    7. The computer automatically generating the test results to be Word document.
    8. Use precision , high stability components, repeat to test , the measurement repetition rate >99.5%.
    9. Finished circuit boards, the surface with special treatment.
    10. The transformer tester has two measurement systems: linear scan and segmented scan.
    11. Amplitude-frequency characteristic complies the national technical specifications.
    12. Test data automatic analysis system, horizontal compare the similarity of A,B ,C, the results as below:
      ①conformance is very good
      ②conformance is good
      ③conformance is bad
      ④serious deformation
      Vertical compare A-A、B-B、C-C, obtain the original data to compare the winding deformation with the test data in the same phase, the results as below:
      ①normal
      ②slight deformation
      ③moderate deformation
      ④serious deformation
    13. Automatically generating Word document,convenient for customers to save and print.
    14. Totally meet the technique conditions of DL/T911-2004:Survey of Frequency Response Analysis on Winding Deformation of Transformers.
