AB  - Purpose– To make easier and faster the designing of transformers using scale models.Design/methodology/approach– The scale modeling in designing of transformers is included. Both computer and physical models of high leakage reactance (HLR) and 3‐phase (TP3C) transformers have been considered. The 3D field computations have been executed for the scaled models, and the results were recalculated to the full‐scaled ones.Findings– It is possible to calculate the scale coefficients for nonlinear models of transformers using finite element method (FEM) software. Obtained coefficients are useful in the designing process. Measurements confirm correctness of the scaling laws.Research limitations/implications– The calculations were done only for transformers and the eddy current was not taken into account.Practical implications– Presented formulae for scale model calculation are very useful for designing of transformers by the engineers. It is possible to design a series of transformers. Only one physical model must be manufactured for experimental verification.Originality/value– This paper offers an innovative approach to non‐linear scaled modelling of transformers using FEM.
