This article describes an investigation of the transformer inner winding deformation, using Sweep Frequency Response Analysis (SFRA). The object of the investigation is a transformer model with functionality of disassembling inner winding and changing configuration of its parts. The purpose of the investigation is to find the characteristic frequency ranges which could be treated as diagnostic bands.
