Wykorzystanie potencjałów magnetycznych A-V i T-Ω do 3-wymiarowej analizy pola w układach transformatorowych z uwzględnieniem prądów wirowych

Eddy current distributions in solid ferromagnetic bulk placed in transformer circuit, were calculated. The tested solid piece have been settled in the 1-phase amorphous magnetic circuit. Two packages (Opera 3D and Maxwell 3D) were used to create mathematical models for the magnetic field analyses. Eddy current losses have been measured and compared with the calculated ones. The verification yields good agreement and correctness of the mathematical modelling.
