This paper focuses on the possibility to use the Bertotti loss theory to describe energy losses in a toroidal core made of grain-oriented steel sheet under non-standard excitation conditions. The temporal Hclas(t) and Hexc(t) dependences are computed using a simple numerical scheme, which may be easily implemented in a spreadsheet.
