In the semi-finished products, finished products in the production process of power transformer, the transformer operation before the installation of the new transformer operation and power system according to the preventive test rules of the State Ministry of electric power, requirements for the transformer turns ratio or regular voltage ratio test. The traditional variable ratio bridge operation is tedious, the reading number is not intuitive, and the necessary conversion is required. The test results are only the data of a phase change ratio. The variable ratio tester overcomes the shortcomings of the traditional variable ratio bridge test. The screen uses a three phase variable ratio test at once, and the test speed is fast and the accuracy is high. The field test time is greatly saved, which brings high efficiency for the customer's test.
The transformer turns ratio test, or TTR test, confirms that the transformer has the correct ratio of primary turns to secondary turns. Using this test correctly can help to identify tap changer performance, shorted turns, open windings, incorrect winding connections and other faults inside transformers. Weshine's range of TTR testers are robust to withstand the harsh conditions that some transformer testing in. The range includes varying features to simplify and speed up testing as well as 3 phase TTR testers and PT and CT TTR testers.
