Portable Digital PT CT Vt 3 Phase Transformer Winding TTR Tester Turn Ratio Meter¹

Product Description Three Phase Transformer Turns Ratio Automatic High-speed Accuracy TesterProduct DescriptionIn 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.Product ParametersPRODUCT INFORMATIONProduct NameTransformer Turns Ratio TesterModel NumberVS-6628Test Range0.9 ~ 10000Accuracy0.1%CertificatesCE; EMC; LVD; ISO;Typical ApplicationTests turns ratio, polarity, vector group and phase deviation.Aids in Identifying * Shorted coils * Open circuits * Incorrect connections * Internal faults or tap-changer defects in step regulators as well as in transformersDimensions260mm * 200mm* 160mmWeight3.5kgCompany ProfileOur Advantages1.
