Abstract. The paper gives brief overview and classification of the coupled problems encountered in electrical apparatus. Three particular problems are considered in more details. These are the problems for coupling electromagnetic field with electric circuit and thermal field, with electric circuit and mechanical motion, and with mechanical motion and electric arc rotation. Results are given for different parameters.

PROBLEMI SPREGNUTIH POLJA
KOD ELEKTRIČNIH APARATA
Prikazan je kratak pregled i klasifikacija problema spregnutih polja kod elektricnih aparata. Tri posebna spregnuta polja su posmatrana detaljnije: elektromagnetno polje, polje električnih kola i temperaturno polje, kada se sistem  kreće  i kada je elektromagnetno polje obrtno. Prikazani su rezultati za razlicite vrednosti uticajnih parametara.
