Automated Transformer Turns Ratio Meter TTR and Transformer Turns Ratio Tester

During the production of semi-finished and finished power transformers, before newly installed transformers are put into operation and in accordance with 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. This can check the correctness of the transformer turns ratio, the condition of the tap changer, whether the transformer has short circuits between turns, and whether the transformers can be operated in parallel. The readings of traditional ratio bridges are not intuitive and can only be measured phase by phase to be converted. The SXBB ratio tester overcomes the shortcomings of traditional ratio bridge testing. It is easy and intuitive to operate and uses a three-phase precision inverter power supply, which makes the test fast and accurate.

1. The instrument uses a three-phase precision inverter power supply, eliminating the harmonic effects of the mains voltage during measurement, ensuring more accurate measurements. It also operates without any issues when powered by a generator.
2. A three-phase output voltage increases test speed and can measure phase angles. It automatically identifies wiring groups 0-11. For low-voltage measurements of rectifier transformers with multiple windings, the low-voltage side can be used to measure the transformation ratio and 7.5° angular deviation without removing wiring.
3. It is compatible with a wide range of transformers, particularly Z-type transformers, rectifier transformers, grounding transformers, furnace transformers, and phase-shift transformers.
4. It features high and low voltage reverse polarity protection, transformer interturn short-circuit protection, tap changer misalignment protection, and output short-circuit protection. enhancing instrument stability.
5. After entering the rated parameters, the instrument automatically measures the transformer ratio, error value, and tap position. It can accurately measure the exact position of transformer tap changers, especially for asymmetrical taps, and can measure tap changers with up to 99 tap positions.

1. Display: 7-inch high-definition color touchscreen LCD with digital backlight adjustment, displays operation menus and test results.
2. High Voltage Terminal: Connect the yellow, green, red, and black test lead terminals to the A, B, C, and O phases on the high voltage side of the transformer under test.
3. Low Voltage Terminal: Connect the yellow, green, red, and black terminals to the A, B, C, and O phases on the low voltage side of the transformer under test.
4. AC220V: Power input port for the entire unit, connect to an AC220V power supply.
5. Communication: Serial communication port.
6. USB: USB flash drive storage.
7. Printer: Prints test results after measurement is completed.
