Imisebenzi ephambili ye-oyile ye-transformer:

(1) I-Insulation: i-oyile ye-transformer inamandla okugquma aphezulu kunomoya. I-insulation igxininiswe kwioli, engaphuculi nje kuphela amandla e-insulation, kodwa iphinde ikhusele kumswakama.

(2) isiphumo sokupholisa: ubushushu obuthile be-oyile ye-transformer bukhulu, kwaye buhlala busetyenziswa njengesipholisi. Ubushushu obuveliswa ngexesha lokusebenza kwe-transformer yenza ukuba ioli isondele kumbindi kunye ne-winding eshushu kwaye yandiswe. Ngokusebenzisa i-convection ephezulu kunye nesezantsi yeoli, ukushisa kuchithwa kwi-radiator ukuqinisekisa ukusebenza okuqhelekileyo kwe-transformer.

(3) ukunyanzeliswa kwe-arc: kwi-oil circuit breaker kunye ne-transformer kwi-switch voltage regulator switch, ukutshintshwa koqhagamshelwano kuya kuvelisa i-arc. Ngenxa ye-conductivity ye-thermal efanelekileyo ye-oyile ye-transformer, kwaye phantsi kwesenzo se-arc ephezulu yokushisa inokuchukumisa inani elikhulu leegesi, okubangela uxinzelelo olukhulu, ngaloo ndlela kuphuculwe ukusebenza kokucima kwe-arc ye-medium, ukuze i-arc iphele ngokukhawuleza.

Emva kokufumana impendulo kumvelisi we-oyile yomgangatho ophezulu, kufuneka wazi ukuba kutheni ioli isetyenziswa kwi-transformer.
