General Information
GDRB-F Transformer winding deformation tester adopts sweep frequency response analysis (SFRA) method to detect transformer winding movements and mechanical failures due to mechanical shock, transportation or short circuits, with features of fast test speed, high frequency stability and powerful analysis software.
Features
- Fast test speed. Single winding is measured within 3 minutes.
- Digital frequency synthesis, with higher frequency stability.
- 5kV voltage isolation fully protects safety of the testing computer.
- Able to load 9 curves at the same time, calculate parameters of each curve automatically, diagnose winding deformations and draw conclusions.
- Powerful analysis software. Software and hardware parameters satisfy national standard DL/T911-2004. (EN60076-18, optional)
- User-friendly management software with high intelligence, simple interface, easy to operate.
- Support basic functions like data analysis, data storage, data export and print.
