WJBC-IV fully automatic ratio group tester (desktop)
1. Overview
The fully automatic transformation ratio group tester uses a highly intelligent CPU chip as the core to automatically measure the transformation ratio, ratio error and polarity of various single-phase transformers and voltage transformers, as well as the transformation ratio and group and transformation ratio error of three-phase transformers. This instrument is powered by a single-phase power supply and automatically generates a three-phase power supply internally. There is no need for an external three-phase power supply. When testing the transformation ratio of a three-phase transformer and voltage transformer, the magnetic circuit is exactly the same as the actual magnetic circuit used, so the transformation ratio and group test results are accurate. Full Chinese menu, simple measurement process and easy to use.
The fully automatic transformation ratio and group tester is carefully designed and developed by our company's scientific researchers and represents the most advanced level of transformation ratio and group tester in the country. It has many original technologies and perfect performance. Its Z-type transformer measurement function and powerful protection function are the first in China:
1. High test accuracy, good stability and good repeatability;
2. Single-phase 220V input, three-phase power output, no need for additional power supply during testing;
3. Different measurement methods can be selected, and the transformation ratio, transformation ratio error, and group can be measured and calculated at the same time;
4. Large-screen Chinese character LCD display prompts, full Chinese operation menu, easy and concise to use.
5. With real-time clock display and printing functions;
6. Various error prompts and protection functions such as high and low voltage reverse connection protection, over-range display, etc., which are easy to use, safe and reliable;
7. It can measure the transformation ratios and groups of various transformers such as Y/Y, D/D, Y/D, D/Y, Z/Y, Y/Z, D/Z, Z/D, etc. It can measure any structure and any group of transformers.
8. There is a micro printer attached to the instrument panel, which can print test data and related information;
9. Small size, light weight, metal box, easy to use.
