The HZBTC-IV Transformer Capacity Characterization Tester is an upgraded model developed by our R&D team on the basis of the original Division I transformer capacity tester. It retains the original instrument's compact size, simple operation, and ease of use, while comprehensively upgrading the internal processor, data acquisition system, and national standard data — enabling a wider range of applications with higher test precision.

The instrument covers transformer capacity, transformer no-load loss, transformer load loss and code level determination, as well as electrical parameter measurement. It features a built-in high-efficiency rechargeable battery that allows operation without an external power supply, and can be fully recharged for more than 200 consecutive transformer measurements. In addition, it provides a three-phase precision 50 Hz sine wave AC test power supply, so measuring transformer capacity and load loss requires no external three-phase test power supply, regulator, booster, or other auxiliary equipment — greatly improving work efficiency.

With advantages such as small size, light weight, high measurement accuracy, good stability, and simple operation, this product can completely replace the previous multi-meter method of measuring transformer loss and capacity. Wiring is simpler, testing and recording are more convenient, and work efficiency is significantly improved.

1. Adopts an ARM + FPGA + ADC architecture with the RT-Thread real-time operating system, making the instrument system more robust and the measurement accuracy higher.
2. 7-inch color high-brightness LCD with an icon touch interface and full English menu.
3. Comprehensive electronic help: every operation includes a wiring diagram and text description, making operation intuitive and simple.
4. Built-in large-capacity memory stores up to 1,000 groups of test data. USB port communication allows field test data to be saved and, per customer requirements, uploaded to a PC.
5. Integrates mainstream wired (RS232) and wireless (Bluetooth, WIFI) communication functions for easy data upload and remote control.
6. Supports program remote upgrade, allowing the instrument program to be upgraded remotely according to customer requirements.
7. Real-time voltage channel and current channel waveform display can be observed under each test interface.
8. Real-time display of voltage, current, frequency, power factor, active power, reactive power, and apparent power of the test circuit through a single interface, facilitating judgment of field wiring.
9. All test results are automatically corrected. Simply enter the relevant parameters (such as temperature and no-load correction factor) to make test results more accurate.
10. Transformer characteristics measurement with a maximum voltage range up to 1,000 V and a maximum current range up to 100 A, equipped with an internal protection circuit — no need to worry about wrong gear selection burning the instrument.
11. Transformer characteristics test voltage and current ranges are highly flexible and easy to expand. Simply connect an external voltage transformer or current transformer to greatly widen the instrument's test range.
