Mechanical　characteristics　analysis　of　normal　and　defective　transformer　windings　with　eccentric　distance　under　short-circuit　(SC)　fault　are　conducted　using　three-dimensional　finite　element　method　(3-D　FEM).　The　change　characteristics　of　maximum　stress　and　displacement　of　defective　windings　with　different　eccentric　distances　of　high　voltage　winding　are　obtained.　It　is　found　that　the　increase　of　the　eccentric　distance　of　high　voltage　winding　may　cause　the　maximum　Von　Mises　stress　of　the　windings　rises　under　the　short-circuit　fault.　But　the　eccentric　distance　has　less　influence　on　the　maximum　displacement　of　the　winding,　comparing　with　that　influence　on　the　maximum　Von　Mises　stress　of　the　windings.　The　results　can　provide　reference　for　the　design　and　maintenance　of　transformers.　©　2017　IEEE.
