Mainly used to test various characteristics of transformers, including but not limited to volt ampere characteristics, error curves, transformation ratios, polarities, angle differences, direct resistance, secondary side circuit checks, etc. ‌

1. Fully functional, meeting the steady-state or transient characteristic testing of excitation, transformation ratio, phase, polarity, secondary winding resistance, load, ratio difference, and angle difference for various types of CT (including high inflection point, large transformation ratio, and transformer bushing CT).
2. With just one test, the angle and ratio differences of CT under 1%~120% rated current and different loads can be obtained. The test results can also be extended to other current ranges and loads.
3. It can test the actual load size and power factor of the transformer.
4. It can complete the excitation test, transformation ratio test, and polarity check of electromagnetic PT.
5. The interface is friendly and beautiful, with a Chinese graphical interface and a 5.7-inch graphic transparent LCD that is visible under sunlight.
6. Adopting a rotating mouse operation, the operation is simple, fast, convenient, and easy to master.
7. The device can store 1000 sets of test data without loss in case of power failure. It can be exported in real-time through a USB flash drive, and historical data can also be retrieved for analysis and comparison.
8. The device is portable and comes with a built-in printer on the panel, which can automatically print the generated test report.
