Description--XHBB128C
In the production process of semi-finished products and finished products of power transformers, before the newly installed transformers are put into operation and according to the preventive test regulations of the Ministry of Electric Power, it is required to conduct turns ratio or voltage ratio tests on the running transformers, so as to check the correctness of the transformer turns ratio, the condition of the tap changer, whether the transformers are short-circuited between turns, and whether the transformers can operate in parallel.
The reading of the traditional ratio bridge is not intuitive, and to be converted, it can only be measured phase by phase. This transformation ratio tester overcomes the shortcomings of the traditional transformation ratio bridge test, and the operation is simple and intuitive.

Features--XHBB128C:
1. The instrument uses a three-phase precision inverter power supply instead of a single-phase mains power supply as the measurement voltage, which eliminates the harmonic influence of the mains voltage during measurement and makes the measurement more accurate. When the working power source is a generator, it has no effect.
2. Adopt three-phase output voltage, improve the test speed, measure the angle between phases, and automatically identify the transformer wiring group 0-11.
3. Wide range of applicable transformers, with Z-type transformer, rectifier transformer, ground transformer, electric furnace transformer, phase-shift transformer, balance transformer, Scott transformer and inverse Scott transformer.
4. The self-made precision three-phase inverter power supply is adopted, which has high and low voltage reverse connection protection, transformer inter-turn short circuit protection, tap switch not in place protection, output full short circuit protection, and increases the stability of the instrument.
5. After inputting the rated parameters, the transformer ratio, error value and tap position of the tap changer can be automatically measured, especially for the tap changer with asymmetrical taps, the exact position of the transformer tap changer can also be accurately measured. A tap changer capable of measuring 99 tap points.
6. Adopt high-definition color liquid crystal, modular liquid crystal display, each operation step has Chinese prompts, no need for manuals, just look at the liquid crystal prompts to complete the instrument operation.
7. The instrument has both print output, U disk interface, and RS232 interface, which is convenient for paperless office.
8. It adopts multi-functional engineering plastic box that is resistant to cold and temperature, is sealed and waterproof, and is anti-drop and shock-proof, which is convenient for field experiments.
