Functional characteristics of transformer ratio tester

1. Automatically measure the wiring group.
2. Automatic group conversion, can directly measure the transformation ratio of single-phase, three-phase transformers and transformers.
3. Automatically switch phase sequence.
4. Automatic switching range.
5. Automatic meter calibration.
6. After inputting the standard transformation ratio, the relative error can be calculated automatically.
7. After a measurement is completed, the test voltage is automatically cut off.
8. The measurement results are automatically saved, the test data can be printed out, and 20 historical measurement data can be stored.
