1.Brief Introduction of Turns Ratio Tester
During the processing of semi-finished products and the finished products in transformer production, the transformer newly installation before commissioning, or according to IEC and national standard, the turns ratio or voltage ratio should be tested in the circle rate. It aims to check the correctness of the transformer turns ratio, the condition of the tap changer, whether the transformer is short-circuited between turns, and whether the transformer can be operated in parallel. TTR-103 three phase transformer turns ratio tester is the update replacement of traditional bridge method. It finishes test of three phase voltage ratio or turns ratio once, fast testing and high precision.
Advantege: 1. It has Neutral point; 2. Can be connected with bluetooth and cellphone controlled with APP control 3. Built-in printer, USB and RS323 Interface. For more details, please contact Lucyelec.
2. Features and Advantages of transformer ratio tester
- Using a three-phase precision inverter power supply as the measurement voltage, which eliminates the harmonic influence of the mains voltage during measurement and makes the measurement more accurate. no influence when working with power generator.
- The three-phase output voltage is adopted to improve the test speed. The phase angle can be measured, and automatically identify the transformer wiring group 0-11. For the low-voltage rectifier transformer measuring multiple windings, the low-voltage side can measure the transformation ratio and the angle deviation of 7.5 ° without removing the wiring.
- 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, etc.
- With high and low voltage reverse connection protection, transformer turn-to-turn short-circuit protection, tap switch failure protection, and output full short-circuit protection, it increases the stability of instrument.
- After input parameters, it can automatically measure the transformer ratio, error value and tap position of the tap changer. Especially for tap changers with asymmetric tapping, it can accurately measure the position of tap changer. A tap switches capable of measuring 99 tap positions.
- Adopt 7-inch high-definition LCD colorful touch screen, modular display, good visibility even under strong light.
- The instrument not only has print output, U disk interface, but also can be equipped with RS232 interface, which is convenient for paperless office.
- With sealed water-proof and shock-proof sturdy hand case, it's cold-resistance, high temperature resistance, which is suitable for field test.
- With Bluetooth function, instrument can be controlled by Android cellphone or ipad.
