Main functional features:

1. Without the need for an external voltage regulator, the tested product can be measured.

2. The instrument uses a 220V low-voltage power supply to automatically apply current to the three-phase high-voltage winding of the transformer, synchronously collect data, and automatically calculate the impedance error percentage. The test results are very intuitive.

3. Equipped with output current limiting function, suitable for any impedance test sample.

4. The instrument operation is very simple, with one-time wiring, and can automatically complete three-phase testing without reversing the test wire.

5. For three-phase transformers, the instrument can be used for single-phase testing or three-phase testing; It can be tested manually or automatically.

6. It has the function of measuring zero sequence impedance.

7. It has the function of measuring inductance.

8. Using a large screen LCD display and a fully Chinese menu style operation, the test can be completed according to the prompts on the screen.

9. Capable of printing and storage; Equipped with a 232 serial port and USB storage, it facilitates the analysis and organization of data.

10. Simple wiring, accurate testing, high level of automation, small size, and light weight.
