Transformateur zikoreshwa mu mazi zikoresha amavuta nk'uburyo bw'ingenzi bwo kwirinda ubushyuhe bwa transformateur kandi zishingikiriza kuri amavuta nk'uburyo bwo gukonjesha (kwikonjesha, gukonjesha umwuka, gukonjesha amazi). Impamvu nyamukuru zo gushyira utubuye mu mwobo w'amavuta wa transformateur ikoreshwa mu mazi ni: gukumira inkongi no gusohora amazi mu mazi.
Iki gice kiri munsi ya transfoma itwikirwamo amavuta gikunze kwitwa pisine isohora amavuta cyangwa pisine isohora amavuta, biganisha ku mwobo w’amavuta wabayemo impanuka cyangwa pisine y’amavuta yabayemo impanuka. Mu gihe habaye impanuka, nko gutera amavuta cyangwa guturika, amavuta ya transfoma azanyura mu mwobo usohora amavuta anyuze mu ibuye ry’amabuye, hanyuma akagera kuri pisine y’amavuta yabayemo impanuka. Muri iki gihe, ibuye ry’amabuye riri munsi ya transfoma rigira uruhare rwo kwitandukanya, rigagabanya umuriro kandi rigafasha kuzimya umuriro; byongeye kandi, transfoma y’ubushyuhe bwinshi Nyuma y’uko amavuta akonjeshejwe n’utubuye, umuriro urashobora kugabanuka.
Zimwe muri pisine zikozwe muri grilles, izindi ntizikozwe. Ku miyoboro, amabuye ashyirwa ku miyoboro; ku badafite imiyoboro, amabuye ashyirwa mu mwobo usohora amavuta. Gushyira amabuye kugira ngo byoroshye gusohora amavuta ni imwe mu mpamvu, kandi ubushyuhe bworoshye bwo kubungabunga, kugenzura abakora, n'akazi nabyo ni impamvu.
Iyo transformateur ifashwe n'umuriro, amavuta aracyashya iyo ava hasi, kandi ntaziba umwobo w'amazi usohokamo amavuta uri munsi y'aho amazi ava. Amavuta atemba ajya hasi hagati y'amabuye y'agaciro ya transformateur, kandi ubuso bwayo ntibuhumanya amavuta. Iyo amavuta avanywemo, akora nk'ubushyuhe bukonjesha amavuta kugira ngo adashya.
