RDB-IIH portable transformer turn ratio tester overcomes the shortcomings of traditional ratio bridge test, which is easy to operate and intuitive. It adopts three-phase precision inverter power supply, and has fast test and high accuracy.
RDB-IIH Transformer Turn Ratio Teste
Product features：
1. Three phase precision inverter is used in the instrument to eliminate the harmonic effect of the mains voltage and make the measurement more accurate. When the working power supply is generator, there is no influence.
2. Three phase output voltage is adopted to improve the test speed. The transformer connection group (0 ~ 11) can be automatically identified.
3. It is suitable for the measurement of a wide variety of transformers, such as Z-type transformer, rectifier transformer, grounding transformer, electric furnace transformer, phase-shifting transformer and balance transformer, with the most comprehensive measurement parameters.
4. High and low voltage reverse connection protection, transformer turn to turn short circuit protection, tap changer opening and closing not in place protection, output full short circuit protection, increase the stability of the instrument.
5. After inputting the rated parameters, it can automatically measure the transformer ratio, error value and tap changer tap position, especially for the tap changer with asymmetric tap connection, it can also accurately measure the exact position of the transformer tap changer, which can measure up to 99 tap changers tap positions.
6. It adopts 7-inch high-definition color touch-screen LCD with modular display, and each operation step has menu prompt, so the instrument operation can be completed only by looking at the LCD prompt without manual.
7. No power down clock and data storage function, with U disk storage function
8. The multi-functional engineering plastic box with cold and temperature resistance, sealing and waterproof, anti-falling and anti-shock is adopted for field test.
9. Small size, light weight, portable operation.
