1.The instrument is used with the precision inverter three-phase measurement power supply, not using a single-phase power supply as the measurement voltage, it can eliminate the mains voltage harmonic effects when measurement, measurement will be more accurate. When the power supply is a generator, there is no influence.

2.The use of three-phase output voltage, three-phase pressurized, three-phase measurement can improve test speed, can identify the transformer wiring group easily 0-11.

3.It can be applied to a wide variety of transformers, with Z-type transformer measurement.

4. The use of precision three-phase inverter power supply, with high and low voltage reverse polarity protection, transformer inter-turn short circuit protection, on-off tap-changer not in place protection, the output short-circuit protection, Which increases instrument stability.

5. After inputting the rated parameter, it can automatically measure the transformer ratio value, error value and on-load tap-changer position, especially for the on-load tap-changer, it can accurately measure the exact position of the tap changer. 99 on-tap tap-changers.

6. 65K true color LCD, modular liquid crystal display, each operation steps have English tips, no need manual, only to see the liquid crystal tips to complete the operation of the instrument.

7. Instrument both print output, U disk interface, but also can be equipped with RS232 interface, ease of paperless office

8. The use of cold and heat resistant, sealed, waterproof, anti shock and multi-function engineering plastic box, easy field test.
