Sažetak

The article presents a numerical solution for the distribution of the electromagnetic and thermal fields of an air-core transformer using the finite element method.
The distribution of the magnetic field is determined for the dynamic steady state and magnetic nonlinear core characteristics.
The model presented facilitates the establishment of criteria for optimizing transformer operation under various load conditions, environments as well as in the case of failures. Thus, the transformer can operate at maximum capacity while, at the same time, the probability of faults due to overheating is reduced to a minimum.
