Sweep Frequency Response Analyzer

GDRZ-902 Transformer Sweep Frequency Response Analyzer

Introduction:
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;
GDRZ-902 Sweep Frequency Response Analyzer for transformer distortions detection
