Portable Transformer Sweep Frequency Response Analyzer SFRA20
Main Features
1. Characteristics of transformer windings are measured with frequency sweep method. Deformations of
windings such as distortion, swell or displacement of 6kV and above transformer are measured by detecting
amplitude-frequency response characteristics of each winding, not requiring lifting of transformer enclosure
or disintegration.
2. Quick measuring, measuring of a single winding is within 2 minutes.
3. High frequency accuracy, higher than 0.001%.
4. Digital frequency synthesis, with higher frequency stability.
5. 5000V voltage isolation fully protects safety of the testing computer.
6. Able to load 9 curves at the same time and automatically calculate parameters of each curve and diagnose
winding deformations to provide the reference diagnosis conclusion.
7. Analysis software has powerful functions and software and hardware indicators .
8. Software management is humanized with high degree of intelligence. You only need to click a key to
complete all measurements after setting of parameters.
9. The software interface is concise and vivid, with clear menus of analysis, save, report export, print, etc.
