MEWOI-UCT-B Blind measurement 3-phase transformer turn ratio tester,transformer turn ratio finder
The Preventive Test Rules of the State Ministry of Electricity require that the transformer be tested periodically for turn-to-turn ratio or voltage ratio, including semi-finished products and finished products in the production process, transformers before putting into operation and during the operation of the power system. The traditional variable-ratio bridge is complicated to operate and its reading is not intuitive. It needs necessary conversion, and the test results only reflect one-phase ratio. MEWOI-UCT-B Transformer Turn Ratio Tester overcomes the shortcomings of the traditional bridge test, completes the three-phase ratio test at one time, has fast test speed and high accuracy, and greatly improves the test efficiency.
1, Wide test range: 0.9-10000.
2, Fast test speed, can complete the single phase test in 10 seconds.
3,Wide suitable types of transformer, with Ζ shape coupling transformer test
4, With blind measurement of turn ratio, automatically group testing functions, tap position test function.
5, Non-power Clock and Date Display, data storage function (can store 50 sets of test data).
|6,Perfect protection function, reverse connect protection function, high and low voltage transformer interturn short circuit protection function.|
|7, Printer output measurements, English menu display, color LCD.|
8, Small size and light weight.
