Abstract :
This paper presents some case studies on the effects of terminal connections that affect Sweep Frequency Response Analysis (SFRA) results. Wrong or different terminal connections might lead to confusing SFRA results which could be misinterpreted in the assessment of transformer winding conditions. Effect of grounding the tertiary winding, opening the tertiary winding, and connecting the neutral point in the terminal connections are highlighted in this work.
