Sweep Frequency Response Analysis (SFRA) is a demonstrated control for investigating the mechanical integrity such as core and bulk winding deformations, open circuit and short circuit, radial and axial buckling etc. A change in frequency response as measured by SFRA technique indicates a good graphical interpretation can give the exact location of fault inside the transformer.
