| Abstract: | Frequency Response Analysis(FRA) is widely used to detect deformation and displacement of windings in power transformers.As the swept frequency method(SFM) has the disadvantages in the width of the analyzable frequency band,sensitivity to the deformation and the test duration,a test System based on Nanosecond Impulse Response analysis was developed to detect slight deformation of transformer windings in this paper.Hardware of the system consists of nanosecond impulse generator,high speed data acquisition,im... |
