1.Iminara yoherejwehamwe na voltage urwego 110kV no hejuru
Muri iyi ntera ya voltage, imirongo myinshi igizwe nuyobora 5. Imiyoboro ibiri ya mbere yitwa insinga ikingiwe, izwi kandi nk'insinga zo gukingira inkuba. Igikorwa nyamukuru cyizi nsinga zombi nukurinda kiyobora gukubitwa ninkuba.
Abayobora batatu bo hasi ni icyiciro A, B, na C bayobora, bakunze kwita imbaraga zibyiciro bitatu. Gahunda yabatwara ibyiciro bitatu irashobora gutandukana bitewe nubwoko bwumunara. Muburyo butambitse, abayobora ibyiciro bitatu bari mumurongo umwe utambitse. Kumurongo umwe wumuzunguruko, hariho na horizontal itunganijwe muburyo bwinyuguti “H”. Kuburyo bubiri cyangwa imirongo myinshi, umurongo uhagaze mubisanzwe byemewe. Birakwiye ko tumenya ko imirongo mike 110kV ifite insinga imwe ikingiwe, bikavamo imiyoboro 4: insinga 1 ikingiwe hamwe nicyuma 3.
2.35kV-66kV ya voltage urwego rwohereza
Imirongo myinshi yo hejuru murirwo rwego igizwe nabayobora 4, muribo hejuru iracyakingiwe naho itatu yo hepfo ni fonctionnement.
3.10kV-20kV ya voltage urwego rwohereza
Imirongo myinshi yo hejuru murirwo rwego igizwe nuyobora 3, ibyiciro byose, nta gukingira. Ibi bivuga byumwihariko kumurongo umwe wohereza. Kugeza ubu, imirongo ya 10kV ahantu henshi ni imirongo yohereza imiyoboro myinshi. Kurugero, umurongo wikurikiranya ugizwe nuyobora 6, naho imirongo ine yumuzingi igizwe nabayobora 12.
4.Umurongo wa voltage ntoya hejuru yumurongo wohereza (220V, 380V)
Niba ubonye umurongo urenze hamwe na kiyobora ebyiri gusa kumurongo muto wa beto hamwe nintera ngufi hagati yabo, mubisanzwe numurongo wa 220V. Iyi mirongo ni gake mu mijyi ariko irashobora kugaragara mubice byicyaro. Abayobora bombi bagizwe nuyobora icyiciro nicyuma kidafite aho kibogamiye, aricyo kizima kandi kidafite aho kibogamiye. Ibindi bikoresho ni 4-imiyoboro ya seti, ni umurongo wa 380V. Ibi birimo insinga 3 nzima na wire 1 itabogamye.
