Audited Supplier In the production process of semi-finished and finished products of power transformers, before the newly installed transformers are put into operation and according to the preventive testing regulations of the State Grid, it is required to conduct regular turn ratio or voltage ratio tests on the operating transformers. The traditional variable ratio bridge operation is cumbersome, the reading is not intuitive, and necessary conversions need to be made. The test result is only the value of one phase change ratio.
The transformer transformer ratio tester overcomes the shortcomings of traditional transformer ratio bridge testing. The screen adopts a large high-resolution LCD display screen, which is convenient for on-site use. It has a Chinese menu prompt function, easy and intuitive operation, and can complete three-phase transformer ratio testing in one go. The testing speed is fast and the accuracy is high.
