■ functional features

▲ the transformer winding deformation tester adopts the frequency sweep method to measure the characteristics of the transformer winding. Without the hanging cover and disassembly of the transformer, by detecting the amplitude frequency response characteristics of each winding, it can accurately measure the distortion, bulge or displacement of the winding for 6kV and above transformers.

▲ the measurement speed is fast, and the measurement time for a single winding is less than 1-2 minutes.

▲ the frequency accuracy is very high, and the accuracy is higher than 0.001%.

▲ digital frequency synthesis, higher frequency stability.

▲ 5000v voltage isolation and sufficient protection test computer.

▲ 9 curves can be loaded at the same time, the relevant parameters of each curve are calculated automatically, the deformation of winding is diagnosed automatically, and the reference conclusion of diagnosis is given.

▲ the analysis software has powerful functions, and the indexes of software and hardware meet the national standard DL / t911-2004.

▲ the software management is humanized and intelligent. After setting the parameters, you can complete all the measurement work by pressing one key.

▲ the software interface is simple and intuitive, and the menus of analysis, storage, report export and printing are clear at a glance.

▲ field wiring is simple and easy to use.
