According to IEC and relevant national standards, the transformer turns ratio test is a mandatory item during the production, user acceptance, and maintenance testing of power transformers. This effectively monitors the quality of transformers during factory delivery and usage, preventing inter-turn short circuits, open circuits, incorrect connections, internal faults in tap changers, or contact failures. The transformer turns ratio tester is designed based on the on-site usage requirements of users, featuring simple operation, complete functions, and stable and reliable data. It can adapt to the needs of turns ratio and group testing for various large, medium, and small transformers.

Features



1. The transformer turns ratio tester provides Chinese menu prompts, making operation simple and convenient.

2. The measurement range of the transformer turns ratio tester is 0.999 to 2000.

3. It supports both single-phase measurement and automatic testing of three-phase windings. Polarity can be measured for both single-phase and three-phase, and the connection group can be selected arbitrarily. It completes the measurement of turns ratio, error, tap position, and tap value for AB, BC, and CA phases in one go, and can automatically identify the group.

4. Fast measurement speed.

5. Portable and suitable for field operations.



Precautions





  • Please read this user manual carefully before use.




  • The transformer turns ratio tester can be used indoors and outdoors, but should avoid rain, corrosive gases, excessive dust, high temperatures, and direct sunlight.




  • When wiring, ensure that the high-voltage side and low-voltage side leads are not reversed.




  • After powering on the transformer turns ratio tester, do not short-circuit or ground the test leads with each other; unused lead clips must be left hanging.




  • When connecting the transformer turns ratio tester, pay attention that the yellow, green, red, and black wires correspond to the A, B, C, and O terminals of the transformer (three-phase terminals and neutral point), and do not connect them incorrectly.
