Abstract In this paper, we propose the design of a transformer with four cores arranged radially to reduce the stray load loss of a 100kVA shell type transformer. Also, the design of the four cores used a magnetic equivalent circuit method taking into account the nonlinear properties. The optimized design reduced no-load losses to 2.29% and stray load losses of the transformer tank to 77.30%.
