By measuring the ratio of the transformer ratio bridge, the operation process is complicated, the measuring range is narrow, already did not adapt the quick rhythm of modern measurement, the high efficiency requirements
So our company adopts the modern electronic technology, the development of a new generation of automatic Variable Ratio Tester. It has the advantages of small volume, light weight, high precision, good stability.
It uses a large screen Chinese characters display, menu operation, friendly interface. Groups can once finish ratio test. The instrument is the ideal test instrument of power industry.
1. Automatically measure the wiring group.
2. Automatically change the group.
3. Automatically switch the phase sequence.
4. Automatically switch the range.
5. Automatically calibrate the meter.
6. Able to automatically calculate the relative error after entry of the standard transformation ratio.
7. Automatically cut off the test voltage after completion of a measurement.
8. Automatically save the setting data and measurement results, and provide past data for viewing.
9. The primary transformation ratio is required to be entered for only one time during measurement of the on-load transformer.
