YDHG-B Transformer integrated tester Is based on the traditional voltage regulator based on voltage regulator, booster transformer volt-ampere characteristics than the polarity of the comprehensive tester, based on a wide range of user comments, after a lot of market research, in-depth theoretical research after the development of new A generation of innovative CT , PT The device is equipped with high performance DSP with FPGA , Advanced manufacturing process, to ensure stable and reliable product performance, complete functions, high degree of automation, high test efficiency, in the leading domestic level, the power industry for the professional testing equipment transformer.

1.1Main technical characteristics

1, Full-featured, both to meet all kinds CT (Such as: protection class, measurement class, TP Class) excitation characteristics (ie, volt-ampere characteristics), variable ratio, polarity, secondary winding resistance, secondary load, the difference and the difference between the test requirements, but also for all types PT Electromagnetic field excitation characteristics, variable ratio, polarity, secondary winding resistance, ratio difference test.

2, Field test current transformers do not require standard current transformers, boosters, load boxes, regulator boxes and high current conductors, using extremely simple test wiring and operation to achieve current transformer verification, greatly reducing the work intensity and Improve the work efficiency, to facilitate the site to carry out field test work on the transformer.

3, Can accurately measure the difference between the difference and the angle difference, the difference between the maximum allowable error ±0.1%, The maximum allowable error of the angle difference ±5min , Can be carried out 0.2SLevel current transformer field test, variable ratio measurement range1~40000.

4, based on The advanced frequency method is used to test the CT / PT volt-ampere characteristic curve and the 10% error curve. The output current is only 180V AC voltage and 12Arms (36A peak) AC current, but can deal with the inflection point up to 60KV CT test.

5, Automatically gives the inflection point voltage /Current, 10%(5%)Error curve, exact limit factorALF ), Instrument security factor (FS ), The second time constant (Ts), The remanence coefficient (Kr), Saturated and unsaturated inductors and so on CT , PT parameter.

6, Test is satisfied GB1208 (IEC60044-1) , GB16847 (IEC60044-6), GB1207And other types of transformer standards, and in accordance with the type and level of the transformer automatically select what criteria to test.

7, Test is simple and convenient, a key to complete CT Direct resistance, excitation, variable ratio and polarity test, and in addition to load testing, CT Other tests are using the same wiring.

8, All Chinese dynamic graphical interface, without reference to the instructions to complete the wiring, set the parameters: dynamic display parameter settings, according to the currently selected test items automatically display its relevant parameters; dynamic display help diagram, according to the current selected test items, Of the wiring diagram.

9, 5.7Inch graphics through the reverse LCD , The sun is clearly visible.

10, Using rotating optical mouse operation, simple operation, fast and convenient, easy to master.

11, The panel comes with a printer that can be automatically generated by printing experiment report.

12, The device can be stored 1000Group test data, power loss is not lost.

13, Easy to carry, device weight <9Kg.
