The KDB-IV fully automatic transformer ratio group tester can effectively monitor the quality of transformer products during factory delivery and use, prevent inter turn short circuits, open circuits, connection errors, internal faults or contact faults of voltage regulating switches.

The KDB-IV fully automatic ratio group tester is based on the original requirements of users' on-site use, making operation more convenient, with complete functions, stable and reliable data, and greatly improving testing speed. Adapt to the needs of ratio testing for various large, medium, and small transformers.

 

1. English menu prompts, simple and convenient operation.
2. Large measurement range of variable ratio: 1-10000
3. Powerful function: It can perform single-phase measurement and automatic testing of three-phase windings. The connection group can be selected, and the transformation ratio, error, connection group and other parameters of AB, BC, CA phases can be measured at once.
4. Fast measurement speed. (Three phase simultaneous measurement only takes a few seconds)
5. Complete one measurement and automatically cut off the test power supply.
6. Set data, automatically save measurement results, and view previous data.
7. Measure the on load transformer and input the transformation ratio only once.
8. Convenient to carry and suitable for field operations.
