A generalized macroscopic representation of electrical steels used in transformer manufacturing industry is developed. The proposed representation is specifically formulated for integration in the finite element method. Usage of the specific technique enables the accurate evaluation of electromagnetic field distribution of transformer cores under heavily saturated conditions. Advantages over conventional...
Amorphous metal core dry-type distribution transformers have a significant place in today power market since they exhibit 60-70% lower no-load losses when compared to the standard steel based transformers. At typical loading regimes these losses are the most significant ones for a distribution transformer. In order to improve the design and to shorten significantly the time to market of such products...
