Transformer Winding Deformation Tester

Transformer Winding Deformation Tester

Type: ZC-206
    Transformer winding deformation tester quantizing windings parameter changes in different frequency domain, according variance, range, extent and trend of frequency response, to decide deformed extent of the windings, and then decide if the transformer was badly damaged or needed major repairs according the testing results. The device with compact structure, it is easy to operate.

Product Features
    1. Use high-speed, high integration microprocessor to sample and control.
    2. Use USB to connect the notebook PC and device.
    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 device with two measurement system: linear scan and sectional 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.
