Detailed Product Description

Transformer SFRA Sweep Frequency Response Analyzer

 

I. Introduction:

Since the structure and reference of transformer are fixed after being made, the frequency response of each winding is almost same normally.

Some cases ,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 based on the idea and the advanced technique.

SFRA-I Transformer SFRA Sweep Frequency Response Analyzer could draw the frequency response curve accurately. Then we compare the curves horizontally or vertically to detect the deformation of the transformer.

And Transformer SFRA Sweep Frequency Response Analyzer is conformed to the standard of DL/T911 2004.
