Imisebenzi esemqoka kawoyela we-transformer:

(1) I-insulation: uwoyela we-transformer unamandla okushisa aphezulu kakhulu kunomoya. I-insulation icwiliswa emafutheni, engagcini nje ukuthuthukisa amandla okushisa, kodwa futhi ivikela ekumswakama.

(2) umphumela wokupholisa: ukushisa okuqondile kwamafutha e-transformer kukhulu, futhi kuvame ukusetshenziswa njengesibambisi. Ukushisa okukhiqizwa ngesikhathi sokusebenza kwe-transformer kwenza amafutha asondele kumongo futhi ashise futhi anwetshwe. Ngokusebenzisa i-convection ephezulu naphansi yamafutha, ukushisa kusakazwa nge-radiator ukuze kuqinisekiswe ukusebenza okuvamile kwe-transformer.

(3) ukucindezelwa kwe-arc: ku-oil circuit breaker kanye ne-transformer ekushintsheni kwesilawuli se-voltage yomthwalo, ukushintshwa kokuxhumana kuzokhiqiza i-arc. Ngenxa ye-conductivity enhle yokushisa yamafutha e-transformer, futhi ngaphansi kwesenzo sokushisa okuphezulu kwe-arc kungathinta inani elikhulu lamagesi, okuholela ekucindezelweni okukhulu, ngaleyo ndlela kuthuthukise ukusebenza kokucisha kwe-arc kwe-medium, ukuze i-arc isheshe icime.

Ngemuva kokuthola impendulo kumkhiqizi we-oyela yezinga eliphezulu, kufanele wazi ukuthi kungani uwoyela usetshenziswa ku-transformer.
