Products features 

Use high-speed, high integration microprocessor to sample and control.

Use USB to connect the notebook PC and device.

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:

     (1)conformance is very good
    (2)conformance is good
    (3)conformance is bad 
    (4)conformance is very bad 
  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:
    (1) normal 
    (2) slight deformation
    (3) moderate deformation 
    (4)serious 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.
