Isigaba sesithathu sekholamu engundoqo kukubeka i-windings emithathu yezigaba ezithathu kwiikholamu ezintathu ezingundoqo ngokulandelelana, kunye neentsika ezintathu ezingundoqo zikwadityaniswe ngeedyokhwe zentsimbi eziphezulu kunye nezisezantsi ukwenza i-circuit magnetic evaliweyo. Ukucwangciswa kwee-windings kufana ne-single-phase transformer. Xa kuthelekiswa nesiseko sentsimbi esinezigaba ezithathu, inqanaba lesithathu lesiseko sekholamu ineentsika ezimbini zentsimbi ezingaphezulu kwicala lasekhohlo nasekunene kwikholamu yentsimbi, ejika ibe yi-bypass. I-windings yenqanaba le-voltage nganye ngokulandelelana inemikhono kumbindi wekholamu ezintathu ezingundoqo ngokwesigaba, ngelixa idyokhwe yecala ingenazo ii-windings, ngaloo ndlela zenza i-five-five-core column transformer.
Ngenxa yokuba i-magnetic flux yesigaba ngasinye sesigaba sesithathu sekholamu yentsimbi engundoqo inokuvalwa yidyokhwe yecala, izigaba ezintathu zeesekethe zemagneti zinokuthathwa njengezizimeleyo, ngokungafaniyo nesigaba sesithathu esiqhelekileyo se-transformer. apho iisekethe zemagnethi zesigaba ngasinye zinxibelelene. Ngoko ke, xa kukho umthwalo we-asymmetric, i-zero-sequence magnetic flux eyenziwa yi-zero-sequence current yesigaba ngasinye ingavalwa yidyokhwe yecala, ngoko ke i-impedance ye-excitation ye-zero-sequence ilingana neyomsebenzi we-symmetrical (ulandelelwano oluhle) .
Izigaba ezintathu kunye neenguqu ezintathu zekholamu ezinomthamo ophakathi kunye omncinci ziyamkelwa. I-transformer enkulu yesigaba sesithathu idla ngokukhawulwa kubude bezothutho, kwaye i-five-five-column transformer isoloko isetyenziswa.
I-iron-shell yesigaba esisodwa se-transformer inomqolo ongundoqo kunye neentsika ezimbini zesebe (ekwabizwa ngokuba yi-jokes zecala), kunye nobubanzi bekholamu ye-central core sisimbuku sobubanzi beentsika ezimbini zesebe. Zonke ii-windings zibekwe kwikholamu engundoqo ephakathi, kwaye iikholamu ezimbini ezingundoqo zesebe zijikeleze icala langaphandle le-windings njenge "shells", ngoko kuthiwa yi-shell transformer. Ngamanye amaxesha ikwabizwa ngokuba yi-single-phase three-column transformer.
