Impinduka zingufu nubwoko bwamashanyarazi akoreshwa muguhana ingufu zamashanyarazi hagati yimirongo ibiri cyangwa myinshi binyuze mumashanyarazi. Yashizweho kugirango ikore kuri voltage nyinshi kandi ni ngombwa mugukwirakwiza no gukwirakwiza amashanyarazi. Impinduka zingufu ziboneka mubisanzwe, aho zimanura amashanyarazi menshi kugirango igabanye urwego rwo hasi rukwiranye no gukwirakwiza amazu nubucuruzi.
Ku bijyanye na metero zingufu,amashanyaraziKugira uruhare runini mugupima neza gukoresha amashanyarazi. Imetero y'ingufu, izwi kandi nka metero ya watt-isaha, ni ibikoresho bipima urugero rw'ingufu z'amashanyarazi zikoreshwa n'inzu, ubucuruzi, cyangwa ibikoresho by'amashanyarazi mugihe runaka. Izi metero ningirakamaro mubikorwa byo kwishyuza no gukurikirana imikoreshereze yingufu.
Mubihe byinshi, cyane cyane mubikorwa byinganda cyangwa inyubako nini zubucuruzi, urwego rwa voltage rushobora kuba hejuru cyane kuri metero zisanzwe zidashobora gukora neza. Aha niho abahindura imbaraga baza gukina. Byakoreshejwe kumanura voltage ndende kugeza kurwego rwo hasi, rushobora gucungwa neza rushobora gupimwa neza na metero yingufu. Iyi nzira ntabwo irinda metero gusa ibyangiritse bitewe na voltage nyinshi ariko inemeza ko ibyasomwe ari ukuri.
Impinduka zingufu zikoreshwa zifatanije na metero zingufu bakunze kwitwa "impinduka zubu" (CTs) na "voltage transformateur" (VTs). Impinduka zubu zikoreshwa mugupima umuyaga unyura mumashanyarazi, mugihe impinduka za voltage zikoreshwa mugupima voltage mumuzunguruko. Ukoresheje izo transformateur, metero zingufu zirashobora kubara neza gukoresha ingufu mukugwiza amashanyarazi yapimwe na voltage.
Kwishyira hamwe kwingufu zamashanyarazi hamwe na metero zingufu ningirakamaro cyane muri sisitemu yibice bitatu, bikunze gukoreshwa mubikorwa byinganda. Muri ubwo buryo, ibice bitatu byumuriro na voltage bigomba gupimirwa icyarimwe. Impinduka zingufu zorohereza ibi mugutanga igipimo gikenewe cyibipimo byamashanyarazi, bigatuma metero yingufu ikora neza.
Byongeye, ikoreshwa ryaamashanyarazimuri metero zingufu zongera umutekano. Sisitemu yo hejuru ya voltage irashobora guteza ibyago bikomeye, harimo amashanyarazi hamwe numuriro. Mu kumanura voltage kurwego rutekanye, impinduka zamashanyarazi zifasha kugabanya izo ngaruka, kureba niba metero yingufu hamwe nibikorwa remezo bikikije bikora neza.
Muncamake, transformateur yingufu nikintu cyingenzi mumikorere ya metero zingufu, cyane cyane mumashanyarazi menshi. Ifasha gupima neza ikoreshwa ryamashanyarazi mukamanura urwego rwa voltage kurwego rushobora gucungwa. Ibi ntibitanga gusa fagitire nogukurikirana imikoreshereze yingufu ahubwo binongera umutekano mumashanyarazi. Gusobanukirwa uruhare rwimpinduka zamashanyarazi muri metero zingufu ningirakamaro kubantu bose bagize uruhare mubikorwa byingufu, kuko byerekana akamaro kibi bikoresho mugukwirakwiza neza kandi neza mumashanyarazi.
