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-LX5265 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, Lithium battery power supply or 100-240V AC power supply is self-adaptive. After one charge, more than 100 transformers can be continuously tested in the ratio group. The test process is simple and convenient. |
2, It has the function of blind measurement, that is, to perform variable ratio and group test when there is no connection between high and low voltage. |
3,Based on the test of conventional transformer, Z-type transformer and PT sample, the polarity test function of CT variable ratio is added, and the application field is wider |
4, Wide range and high accuracy, the variable ratio measurement range can reach 10,000, and the test accuracy can be guaranteed 0.3% when the maximum value is 10,000. |
5, It has perfect protection functions such as reverse connection protection and output short circuit protection. |
| 6,5.6-inch super industrial high-brightness color LCD screen, still visible under strong sunlight. |
7, equipped with external printer, facilitate data printing |
| 8, It can be stored locally and on USB memory. |
