[en] In this paper the perturbation technique is developed for modeling a power transformer. The paper analyses the influence of frames on the magnetic field behaviour and on the core losses calculation. Two types of frames are considered: frame manufactured with steel and frame of the steel with a copper layer. The model considers the eddy currents in copper layer of the frame and its effects on the magnetic field behaviour of the core.
