TAC750E CT/PT Tester (Power frequency method)

1. The use of voltage method for one-time wiring test can simultaneously complete CT excitation characteristics, ratio, polarity, and secondary winding DC resistance testing, improving work efficiency;

2. When measuring the ratio and polarity of current transformers, there is no need to short-circuit other secondary windings, which improves work efficiency;

3. Apply AC current to the CT secondary circuit for load measurement of the secondary circuit;

4. Isolate the output voltage from the input power supply to ensure equipment and personal safety;

5. The output voltage frequency of the experiment is independent of the input power frequency, and the output voltage frequency can be selected as 50Hz or 60Hz;

6. It can be boosted to 2000V without the need for an external booster;

7. Fully automated testing does not require manual adjustment;

8. Automatically draw 5% and 10% error curves;

9. It has the function of current boost and hold, used for testing the transformation ratio, polarity, and secondary circuit inspection of current transformers;

10. Equipped with boost holding function, used for secondary AC withstand voltage test;

11. Large screen transparent LCD display, which can display clearly both indoors and outdoors;

12. The ultra large capacity storage can store test data for 20000 sets of windings;

13. Use a USB flash drive to transfer data files and upgrade software;

14. The inflection point voltage shall be calculated according to the IEC60044-1 standard;

15. Switch between Simplified Chinese and English operation interfaces at will.
