Identification of Trouble of Transformer by Frequency Response Analysis

Frequency Response Analysis (FRA) is capable of detecting troubles of transformers, such as deformation of winding, displacement of winding and deformation of iron core, by detecting change of transfer function. However, interpretation of the change with reference to the trouble is not clear. In thi...
