Shanghai Transformer Ratio Tester Manufacturer - overcomes the shortcomings of traditional ratio bridge testing, completes three-phase ratio testing in one go, with fast testing speed and high accuracy, greatly improving testing efficiency.
Transformer ratio testerOverview
The Preventive Testing Regulations of the Ministry of Electric Power require regular turns ratio or voltage ratio testing of transformers, including semi-finished and finished products during production, transformers before commissioning, and transformers during operation in the power system. The traditional variable ratio bridge is cumbersome to operate, the readings are not intuitive, necessary conversions are required, and the test results only reflect one phase ratio. Overcoming the shortcomings of traditional variable ratio bridge testing, the three-phase variable ratio testing can be completed in one go, with fast testing speed and high accuracy, greatly improving the efficiency of the experiment.
