GDRZ-902 Transformer SFRA Sweep Frequency Response Analyzer
Product Description
GDRZ-902
Transformer SFRA 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.
GDRZ-902 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.
GDRZ-902 Transformer SFRA Sweep Frequency Response Analyzer is conformed to the standard of DL/T911 2004.
Application
1. During routine test of power transformer maintenance, our GDRZ-902 Transformer Sweep Frequency Response Analyzer SFRA is used to check the frequency response data of transformer winding.
2. When the power transformer leaves the factory, our GDRZ-902 Transformer SFRAt is used to measure the winding frequency response data of the transformer as the characteristic fingerprint information of the transformer.
3. After the power transformer is short-circuited, our GDRZ-902 Transformer Sweep Frequency Response Analyzer is used to measure the frequency response data of the power transformer and compare it with the test data before the short-circuit to check whether the transformer windings are deformed.
