Tank loss for different leads arrangement

High current leads in transformer can cause high stray losses and/or high temperature rises. This paper gives an overview of the advantages and disadvantages of different leads arrangement. All calculations are done for a 220 MVA transformer with finite element method. Seven different arrangements are considered and compared – an arrangement with no leads, an arrangement with Y-connected leads and five different arrangements with -connected leads.
