1. The instrument adopts three-phase precision inverter power supply, which eliminates the harmonic influence of mains voltage during measurement, and the measurement is more accurate. When the working power supply is a generator, it has no effect.
2. The three-phase output voltage is adopted to improve the test speed. The included angle between phases can be measured and the wiring group 0-11 can be automatically identified. For the rectifier transformer with multiple windings at low voltage, the transformation ratio and angle deviation of 7.5 ° can be measured without disconnection at the low voltage side.
3. It is applicable to a wide variety of transformers, especially for the measurement of Z-type transformer, rectifier transformer, grounding transformer, electric furnace transformer, phase-shifting transformer, balance transformer, Scott transformer, inverse Scott transformer and so on.
4. It has high and low voltage reverse connection protection, transformer turn to turn short circuit protection, tap changer opening and closing not in place protection, output full short circuit protection, so as to increase the stability of the instrument.
5. After inputting the rated parameters, it can automatically measure the transformer ratio, error value and tapping position of the tap changer. Especially for the tap changer with asymmetric tapping, it can also accurately measure the accurate position of the transformer tap changer. It can measure the tap changer with 99 tapping points at most.
6. It adopts 7-inch high-definition color touch screen LCD, modular display and clear display under strong light.
7. The instrument has both printout, USB flash disk interface and RS232 interface, which is convenient for paperless office.
8. The multi-functional engineering plastic box with cold and temperature resistance, sealing, waterproof, fall and shock resistance is adopted for field test.
9. the instrument can use Android mobile phone or tablet, pay attention to WeChat official account, Download APP, control software through special software, test data storage and upload, and facilitate access.
