I.Preface


      During the processing of the semi-finished products and the finished products in transformer production, the transformer newly installation before using, or according to IEC and national standard, the turns ratio or voltage ratio should be tested in the circle rate. Traditional bridge method is complicated, and can’t read the data directly, and you have to make conversion, the testing results are data of one phase. Turns ratio tester of HZBB-10A overcomes the shortcomings of traditional bridge method. The monitor adopts big screen with lattice liquid crystal, which has the function of indicating by menu, operating easily and directly. It finishes test of three-phase voltage ratio or turns ratio once, fast testing and high precise.


II. Functions And Characters


1. The three-phase precision inverter power supply is used inside the instrument, which eliminates the influence of harmonics of the mains voltage during measurement, and the measurement is more accurate. When the working power source is a generator, there is no impact.

2. Three-phase output voltage is adopted to improve the test speed. The angle between phases can be measured, and the wiring group 0-11 can be automatically identified. For low-voltage rectifier transformers with multiple windings, the low-voltage side does not need to be disconnected to measure the transformation ratio and 7.5° Angle deviation.

3. It is suitable for a wide variety of transformers, especially suitable for the measurement of Z-type transformers, rectifier transformers, grounding transformers, electric furnace transformers, phase shifting transformers, balance transformers, etc.
4. It has high and low voltage reverse connection protection, transformer turn short circuit protection, tap switch failure protection, output full short circuit protection, and increased instrument stability.

5. After inputting the rated parameter, it can automatically measure the transformer ratio value, error value and on-load tap-changer position.

6. Adopt 7-inch high-definition color touch-screen LCD, modular display, clear display even under strong light.

7. The device can be equipped with both print output, USB port and RS232 port, which is convenient for paperless office.

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