Product introduction

Using variable ratio bridge measuring transformer turns ratio, the operation process is complex, and the measuring range is narrow, already did not adapt the modern measurement of fast rhythm, high efficiency requirements. For this reason, I plant the use of modern electronic technology, developed a new generation of automatic ratio groups of test instrument, the apparatus is power industry sector is the ideal testing instrument. It has the advantages of small volume, light weight, high precision, good stability and so on. It uses a large screen liquid crystal display Chinese characters, menu operation, friendly interface, ratio of groups can be once finished testing.

The main functions and features

1. automatic measurement wiring group.
2. automatic group transform, which can directly measure the single-phase, three-phase transformer and the transformer turns ratio.
3. automatic switching sequence.
4. automatic range switching.
5. automatic calibration.
6. the input standard ratio, can automatically calculate the relative error.
7. a measurement, automatic cutting test voltage.
8. the measurement results are automatically saved, can print out the test data, and can store 20 times historical data.
