MEWOI-UCT-B Blind measurement 3-phase transformer turn ratio tester,ttr tester,transformer turn ratio finder,MEDIDOR DE RELAÇÃO DE TRANSFORMAÇÃO,Medidor de Relação em Espiras
INTRODUCTION
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 in o 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-C 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. |
MAIN FEATURES
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. |
| 9, Power Supply: AC Power supply for DC Power supply(Built-in battery) |
