During the production process of semi-finished products and finished products of power transformers, before the newly installed transformers are put into operation and in accordance with the preventive test procedures of the National Electric Power Ministry, it is required that the transformers in operation be regularly tested for the turns ratio or voltage ratio. The traditional variable bridge operation is cumbersome, the reading is not intuitive, and the necessary conversion is performed. The test result is only a phase change ratio. The automatic ratio change tester overcomes the shortcomings of the traditional turn ratio test. The instrument completes the three-phase ratio test at a time, and the test speed is fast and the accuracy is high.
