  • Product Introduction

The National Electric Power Department's Preventive Test Procedures requires periodic turns ratio or voltage ratio tests, including semi-finished and finished products in the production process, transformers before operation and during operation in the power system. The traditional variable ratio bridge operation is cumbersome, the reading is not intuitive, and the necessary conversion is required, and the test result only reflects the one-phase transformation ratio. The instrument overcomes the shortcomings of the traditional variable ratio bridge test, and completes the three-phase ratio test at one time, and the test speed is fast and the accuracy is high, which greatly improves the test efficiency.
