HEC-I Fully Automatic Ratio Group Tester

Using a variable ratio bridge to measure the transformation ratio of a transformer is cumbersome to operate and has a narrow measurement range, which is no longer suitable for the fast-paced and high-efficiency requirements of modern measurement. To this end, our company has developed a new generation of fully automatic variable ratio group tester using modern electronic technology. It has a small volume, light weight, high precision, and good stability. It adopts a large screen Chinese character display, menu operation, and user-friendly interface. The variable ratio group can be tested in one go. This instrument is an ideal testing device for the power industry sector.

Functions and features of HEC-I fully automatic ratio group tester:
1. Automatically measure the wiring group.
2. Automatically perform group transformation and directly measure the transformation ratio of all transformers.
3. Automatically switch phase sequence.
4. Automatically switch range.
5. Automatic calibration table.
After inputting the standard transformation ratio, the relative error can be automatically calculated.
7. Once the measurement is completed, the test voltage will be automatically cut off.
8. Set data, automatically save measurement results, and view previous data.
9. Measure the on load transformer and input the transformation ratio only once.
