Sažetak
Due to the large number of thin laminations in the transformer core, homogenization of the core is necessary. Thus, new material of anisotropic characteristics is calculated. Anisotropic electrical conductivity tensor then allows large eddy current loops to be taken into account directly. In the case of low- frequency time-harmonic generator current, the influence of narrow eddy current loops on the distribution of the magnetic flux density within a domain can be taken into account by using additional manually calculated anisotropic magnetic reluctivity tensor. Therefore, no modification of the standard weak formulation of the magnetodynamics problem is required. The only code implementation is required in postprocessing to account for losses due to narrow eddy current loops. A real-size model is used as a numerical example.
