XHBB128B Transformer Turn Ratio Tester
Description
In the production process of semi-finished and finished power transformers, before the newly installed transformer is put into operation and according to the preventive test regulations of the Ministry of Electric Power, it is required to test the turns ratio or voltage ratio of the operating transformer, and the transformer turns ratio can be checked. The correctness, the condition of the tap changer, whether the transformer is short-circuited between turns, whether the transformer can be operated in parallel. The reading of the traditional ratio bridge is not intuitive, and the conversion can only be carried out phase by phase. This transformation ratio tester overcomes the shortcomings of traditional transformation ratio bridge testing. It is easy and intuitive to operate. It adopts three-phase precision inverter power supply, which has fast testing and high accuracy.

Features
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, there is no influence.
2. The use of three-phase output voltage improves the test speed, can measure the angle between phases, and automatically identify the transformer wiring group 0-11.
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 and other transformers, with the most comprehensive measurement parameters.
4. Using self-made precision three-phase inverter power supply, with high and low voltage reverse connection protection, transformer turn short circuit protection, tap switch failure protection, output full short circuit protection, and increase the stability of the instrument.
5. After inputting the rated parameters, it can automatically measure the transformer ratio, error value and tap position of the tap changer. Especially for tap changers with asymmetric tapping, the accurate position of the tap changer of the transformer can also be accurately measured. A tap switch capable of measuring 99 tap positions.
6. Using 7-inch high-definition color touch-screen LCD, modular display, each operation step has Chinese prompts, no manuals are needed, and the operation of the instrument can be completed only by looking at the LCD prompts.
7. The instrument not only has print output, U disk interface, but also RS232 interface, which is convenient for paperless office.
8. It adopts multifunctional engineering plastic box which is resistant to cold and temperature, is sealed and waterproof, and is anti-fall and anti-vibration, which is convenient for field test.
