What is the full name of this battery-powered turns ratio tester?
Battery Operated TTR Transformer Turns Ratio Test Set transformation ratio of a transformer using a ratio bridge is a cumbersome process with a narrow measurement range, which no longer meets the fast-paced and efficient requirements of modern measurements. Therefore, our factory has adopted modern electronic technology to develop a new generation of fully automatic transformation ratio and group type tester. The transformer transformation ratio fully automatic tester has the advantages of small size, light weight, high precision, and good stability. The Battery Operated TTR Transformer Turns Ratio Test Set transformer transformation ratio fully automatic tester uses a large-screen liquid crystal display with Chinese characters and menu operation, and the interface is clear. The transformation ratio and group type can be measured at one time. The transformer transformation ratio fully automatic tester is an ideal testing instrument for the power industry departments.
What key pain points of traditional testing does it primarily address?
1. Automatically measure the connection group.
2. Automatically perform group conversion and can directly measure the transformation ratio of single-phase, three-phase transformers and transformers with mutual inductance.
3. Automatically switch the phase sequence.
4. Automatically switch the range.
5. Automatically calibrate the instrument.
6. After inputting the standard transformation ratio, it can automatically calculate the relative error.
7. The measurement is completed in one go, and the test voltage is automatically cut off.
8. The measurement results are automatically saved. Test data can be printed out and 20 historical measurement data can be stored.
