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.
