Use the transformation ratio bridge for measuring the transformation ratio has failed to meet the fast-tempo and high-efficiency requirements of modern measurement because the tedious operation process and narrow measurement range. To this end, our company has developed the new generation of full-automatic transformation ratio & group tester. It has small volume, light weight, high accuracy, and good stability. It uses a large screen for character display and menu operation, with a friendly interface. The transformation ratio & group can be tested by once. This equipment is an ideal product for the electric power sector.
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, provide past data for viewing.
9. You only need to input the primary transformation ratio for measure the on-load transformer.
