When using the radio bridge to measure the transformer ratio, the operation procedure is complex, the measuring measure range is narrow, which is no longer meeting modern fast-paced, high-efficiency requirements. Therefore, we use the modern electronic technology, developed a new generation of automatic ratio group tester. It is small, light, high accuracy and with good stability. It uses a large-screen character display, menu operation, friendly interface. The ratio group can measure at once.
1. Automatic measurement wiring group;
2. Automatic group transformation;
3. Automatic switching phase sequence;
4. Automatic shift ranging;
5. Automatic calibration;
6. Input the standard ratio, it can automatically calculate the relative error;
7. When the measurement is completed, it can cut off the testing voltage automatically;
8. Setting the data, the measured results can be saved automatically, and can be view the previous data;
9. Measuring loaded transformer ratio, only need to enter once.
