1. Multi-functions:
| Parameters Testing | Single Phase Transformer | 3 Phase Transformer |
| Turns Ratio Testing | Yes | Yes |
| Phase Angle Testing | Yes | Yes |
| Polarity Testing | Yes | Yes |
| Vector Group Testing | / | Yes |
2. Blind test function: There is no need to select the wiring method and group, and the measurement of Y/△, △/Y transformers does not require external short-circuit, and the wiring method can be automatically switched according to the selected test content.
3. Tap test: It can quickly measure the transformation ratio and transformation ratio error at each tap changer position. The rated transformation ratio only needs to be input once, and the transformation ratio error of each tap position can be calculated without repeated input.
4. The magnitude and phase relationship between various voltages and currents are visually represented by vector diagrams, so that users can easily understand the actual meaning of each parameter.
5. The test source used by this instrument is a digitally synthesized standard sinusoidal digital source with a distortion degree of less than 0.1% and is not affected by the quality of the working power supply
