TAC750E CT/PT Tester (Power frequency method)

Instrument Transformer Testing

The TAC750E instrument transformer analyzer is designed for testing the excitation characteristics, ratio, polarity, CT secondary winding DC resistance, and CT secondary circuit load of current and voltage transformers in the field of relay protection.

FEATURES

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.
