Abstract in different language: This paper presents the implementation of the Preisach hysteresis model of a soft magnetic material. The model application is especially useful in the study of transition effects in power transformers like an inrush current or a ferroresonance. The main problem in the use of the Preisach model is to find a suitable weighting function. We considered two basic methods: estimation and systematic derivation. Application of both the methods revealed that the systematic method leads to a better agreement with the experiment. However both results are applicable for investigation of annealed grain oriented steel in transformer core.
