Umlinganiselo weTransformer wokumelana ne-DC yinxalenye ebalulekileyo yovavanyo lwe-transformer.Ngokusebenzisa umlinganiselo wokumelana ne-DC, kunokwenzeka ukujonga ukuba i-condutive circuit ye-transformer ikwimeko embi, i-welding engafanelekanga, ukusilela kwekhoyili kunye neempazamo zocingo kunye noluhlu lweziphene.

Okubizwa ngokuba yi-DC ukuchasana kwe-transformer kubhekiselele kwixabiso lokuxhathisa le-DC kwisigaba ngasinye sokujikeleza kwe-transformer.Injongo yokulinganisa kukukhangela ukuba kukho i-inter-turn short circuit ngaphakathi kwesigaba sesithathu somoya we-transformer.Ngenxa yokuba ukuba kukho isiphaluka esifutshane sesigaba-kwisigaba ngaphakathi kwe-transformer, i-short-circuit current iya kuba nkulu kakhulu, kwaye kunokwenzeka ukuba itshise i-transformer.
Nangona kunjalo, ukuba kukho isiphaluka esifutshane phakathi kokujika kwesinye sezigaba, i-short-circuit current ingaba yincinci kakhulu, kwaye ukukhuselwa kwegesi ye-transformer kuya kuhamba, kodwa kunzima ukubona ukuba i-transformer ngokwayo iphosakele.
Ngeli xesha, ukulinganisa ixabiso lokumelana ne-DC kwisigaba ngasinye se-transformer, kwaye emva koko ngokuthelekisa amaxabiso okumelana nesigaba sesithathu, kulula ukugweba ukuba kukho i-inter-turn short circuit ngaphakathi.Ukuba ixabiso le-inter-phase resistance value lihluke kakhulu, ithuba lokuba i-inter-turn-short-circuit fault inkulu kakhulu.Ukuba ixabiso lokumelana kwesinye sezigaba likhulu kakhulu okanye lingenasiphelo, lithetha ukuba ikhoyili yesi sigaba iphukile.Ukuba ukuchasana kwe-interphase kufana ngokusisiseko, ukunokwenzeka kwesiphaluka esifutshane phakathi kokujika kunokutshitshiswa.
Ngokuqhelekileyo, xa umthamo olinganisiweyo we-transformer ungatshintshi, ukuxhatshazwa okukhulu kwe-DC, ilahleko enkulu yobhedu kunye nokushushumbisa kwe-transformer.Ukuba ukuchasana kwe-DC kukhulu kakhulu, i-transformer iyatshisa kakhulu, kwaye i-transformer itshiswa ngokulula.
