Kubalulekile ukuqwalasela izinto ezininzi ezibalulekileyo xa ufaka kwaye usebenzisa ii-current transformers (CTs) ukuze kuqinisekiswe ukusebenza kakuhle kunye nokhuseleko. Indawo ye-current transformer kufuneka ikhethwe ngokusekelwe kwiimfuno ezithile zokulinganisa kunye nokukhusela. Kungoko ke kubalulekile ukuba inkqubo yombane ihlolwe kakuhle ngaphambi kokufakwa ukuze kuchongwe indawo efanelekileyo ye-CT. Indawo echanekileyo inokuphucula kakhulu ukuchaneka kokulinganisa kunye nokuthembeka kwesicwangciso sokukhusela.
Indlela yokufakelwa kweentambo esetyenziswa kwi-current transformer nayo ibaluleke kakhulu ngokwendlela esebenza ngayo. Kukho iindlela ezahlukeneyo zokufakelwa kweentambo, kuquka ne-single-phase,inkwenkwezi enamanqanaba amathathu (uqhagamshelo luka-Y)kunyei-delta yesigaba esithathu (uqhagamshelo lwe-Δ)Indlela nganye ineenzuzo zayo kwaye ifanelekile kwiindlela ezahlukeneyo zokusebenza. Umzekelo, ukufakelwa kweenkwenkwezi zesigaba sesithathu kudla ngokufanelekile kwimithwalo elinganisiweyo, ngelixa ukufakelwa kwentambo ye-delta kuluncedo kwiinkqubo ezingalinganiyo. Kubaluleke kakhulu ukukhetha indlela efanelekileyo yokufakelwa kwentambo ukuze kuthintelwe iisekethe ezivulekileyo zesibini, ezinokubangela ukufundwa okungachanekanga kunye nomonakalo onokubakho kwi-transformer.
Ngaphezu koko, xa ufaka i-current transformer yeInjini ye-AC, kubalulekile ukuqwalasela umthwalo kwicala lesibini. Ukulayisha kakhulu i-CT kunokubangela ukugcwala, okunokukhokelela ekulinganisweni okugqwethekileyo. Ngoko ke kubalulekile ukuqinisekisa ukuba umthwalo odibeneyo awudluli umthwalo olinganisiweyo ochazwe yi-transformer.
Ngaphezu koko, kubalulekile ukuqinisekisa ukuba ukufakelwa kuyahambelana nazo zonke iikhowudi kunye nemigangatho yombane efanelekileyo, kwaye zonke iintambo zombane zikhuselekile. Ukugcinwa rhoqo kunye nokuvavanywa kweetransformers zangoku kuyacetyiswa ukuqinisekisa ukuchaneka kwazo okuqhubekayo kunye nokuthembeka.
