PS-BB101A Three-Phase Transformation Turn Ratio Tester
The power transformer shall be regularly tested for turns ratio or voltage ratio, including semi-finished products and finished products in the production process, transformers before putting into operation and during operation in the power system. The traditional transformation ratio bridge is cumbersome to operate, the reading is not intuitive, the necessary conversion is needed, and the test results only reflect a phase transformation ratio. The instrument overcomes the shortcomings of the traditional transformation ratio bridge test, completes the three-phase transformation ratio test at one time, has fast test speed and high accuracy, and greatly improves the test efficiency.
