PECULIARITIES OF CALCULATION OF MAGNETIC SYSTEMS WITH SHORT-CIRCUITED SECONDARY WINDINGS IN IN-PLANE FORMULATION

Introduction. A feature of quasi-static calculation of plane electromagnetic fields is unlimited volume occupied by the current. This condition imposes certain requirements on the choice of boundary conditions for solving such problems (the vanishing of the algebraic sum of the currents flowing thro...
