During the production of semi-finished and finished power transformers, before new transformers are put into operation, and in accordance with the preventive test procedures of the State Grid, it is required to periodically test the turns ratio or voltage ratio of running transformers. Traditional ratio bridges are cumbersome to operate, their readings are not intuitive, and necessary conversions are required. Moreover, their test results only show the ratio value of one phase.
The HZBB-II Transformer Turns Ratio Tester overcomes the shortcomings of traditional ratio bridges. It features a large high-resolution LCD screen, a lithium battery power supply for convenient on-site use, and English menu prompts for simple and intuitive operation. It completes three-phase ratio tests in one go with high speed and accuracy.
