HZBB-10A Battery Operated TTR Transformer Turns Ratio Test Set-Huazheng Electric Manufacturing (Baoding) Co., Ltd

HZBB-10A Battery Operated TTR Transformer Turns Ratio Test Set

Functional Characteristics

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

2. By using three-phase output voltage, the testing speed can be improved, and the phase to phase angle can be measured. The wiring group can be automatically identified as 0-11. For low voltage rectifier transformers with multiple windings, the low voltage side can measure the transformation ratio and angle deviation of 7.5 ° without the need to disassemble the wires.

3. Suitable for a wide range of transformer types, especially suitable for measuring Z-type transformers, rectifier transformers, grounding transformers, electric furnace transformers, phase-shifting transformers, and other transformers.

4. Equipped with high and low voltage reverse connection protection, transformer turn to turn short circuit protection, tap changer off/off protection, output full short circuit protection, and increased instrument stability.

5. After entering the rated parameters, the transformer ratio, error value, and tap changer position can be automatically measured, especially for tap changer with asymmetric tap changer. The accurate position of the transformer tap changer can also be accurately measured, with up to 99 tap changer positions.

6. 7-inch high brightness touch color LCD, clear display under strong light, full touch screen operation, free switching between Chinese and English

7. The instrument has both print output and USB interface, and can also be equipped with RS232 interface for paperless office.

8. Adopting a multifunctional engineering plastic box that is cold and temperature resistant, sealed and waterproof, and resistant to falls and shocks, it is convenient for field testing.
