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 in service, 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 actual field usage requirements of users, featuring simple operation, complete functions, and stable and reliable data. It can meet the testing needs of various large, medium, and small transformers for turns ratio and connection group.

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 can complete the measurement of turns ratio, error, tap position, and tap value for phases AB, BC, and CA in one go, and can automatically identify the connection group.

4. Fast measurement speed.

5. Portable and suitable for field operations.



Precautions





  • Please read this instruction manual carefully before use.




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




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




  • After the transformer turns ratio tester is powered on, 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, note 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.
