Abstract :
The accurate computation of stray loss is needed to find ways of lowering the losses. In this paper, the stray losses induced in the flitch plates, frames, and tank walls are investigated. A 3-D transformer model is considered to calculate the stray losses. In order to estimate the stray loss on a power transformer, the stray flux, eddy current, and etc. are analyzed by 3-D finite element method (FEM).
