GDRZ-902 Transformer Winding Deformation Tester, SFRA Sweep Frequency Response Analyzer
Introduction:
Sweep Frequency Response Analyzer for Transformer Winding Deformation Detecting
The structure and reference of the transformer is fixed after been made, Therefor, the frequency response of each winding will be almost the same normally;
Some case such as cut off between circles or phases in experience, cut off or winding moved for the pull of power in running, winding moved for hit in transportation, could change the reference of the transformer ,of which the frequency response will be changed, we could detect the deformation according to the frequency response curve;
Our company has designed the winding deformation tester base on the idea and the advanced technique;
It could draw the frequency response curve accurately. Then we compare the curves horizontally or vertically to detect the deformation of the transformer;
The tester is conformed to the standard of DL/T911 2004;
Features:
| 1 | Using the advanced technical of DDS; |
| 2 | Using the high speed and advanced microprocessor to design; |
