Igice Gikuru cy'Impeta gikoreshwa mu ikoreshwa ry'amashanyarazi mu muyoboro w'impeta kugira ngo gihuze amasoko abiri y'amashanyarazi cyangwa ibice by'akabati k'impeta. Inshingano nyamukuru ni ukugabanya ibice bibiri, hamwe n'imikorere imwe n'ingano nto. Akabati ko hagati ni ubwoko bw'akabati k'impeta gakoreshwa n'abakoresha ba nyuma, gafite imikorere yuzuye n'ingano nini. Hari ubwoko bwinshi bw'akabati ko hagati, gashobora kugabanywamo utubati tw'impeta twinjira n'isohoka, utubati two gupima, utubati tw'impeta, n'utubati tw'impeta twakoreshejwe. Utubati two hagati dushobora gushyirwamo ibikoresho byo kurinda byikora. Mu gihe habaye impanuka, igikoresho cyo kurinda cyohereza ikimenyetso cyo gukora impeta. Igikorwa kinyuramo kandi kikagabanya amashanyarazi. Inyinshi muri VS1 vacuum circuit breakers zikoreshwa mu kabati. Bitewe n'ikoreshwa ritandukanye, imiterere n'uburyo ibice byombi bitoranywa bitandukanye cyane.
Muri sisitemu yo gutanga no gukwirakwiza amashanyarazi, hagomba kwitabwaho gupima ingufu nyinshi aho gupima ingufu nke; gupima ingufu nke bishobora kwitabwaho gusa iyo nta buryo bwo gushyiramo gupima ku ruhande rufite ingufu nyinshi; muri iki gihe, akabati gapima ingufu nke kagomba gushyirwa ku ruhande "rw'imbere". Ni ukuvuga, imbere y'umurongo winjira ufite ingufu nke n'inyuma ya transformateur, ariko akabati gapima ntigashobora kuba karinzwe n'akabati gapima ingufu nke, bityo mu bihe bisanzwe, kagomba kuba karinzwe n'imashini ihindura ingufu nyinshi ya transformateur. Muri iki gihe, akabati gafite umuyoboro w'impeta n'akabati ko hagati birashobora gukoreshwa.
Kugeza ubu, Ring Main Unit ntabwo ishobora gushyirwamo ibikoresho by'amashanyarazi bihuza amashanyarazi, ahubwo ishobora no gushyirwamo ibikoresho bigabanya amashanyarazi, nka XGN yo mu rugo, Schneider's SM6, Siemens 8DJH, ABB's SAFE, nibindi, kandi uburinzi bw'inyongera bushobora gushyirwamo igikoresho cyo kurinda mudasobwa nto. Ariko, circuit breaker yashyizwe mu gice cy'ingenzi cy'iringi ifite umupaka w'umutwaro, kandi imipaka y'igice cy'ingenzi cy'iringi cya buri ruganda iratandukanye. Nka Schneider RM6 Ring Main Unit, uburinzi bw'ingufu nini ya transformer buruta cyangwa bungana na 2000KVA, kandi uburinzi bw'ingufu nto za VIP300 bugomba gukoreshwa. Umutwaro ku mirongo yinjira n'isohoka y'akabati ko hagati ntabwo ubuzanywa.
Birumvikana ko bitewe n’iterambere ry’ikoranabuhanga rigezweho ryo gutanga ingufu z’amashanyarazi, ubwoko bwombi bw’amabati bwateye imbere cyane. Amabati yo hagati arimo kuba mato cyane; Itsinda rikuru rya Ring riri kugenda rirushaho gukora neza; ariko muri rusange, amabati yo hagati akoreshwa mu bikoresho byo kugenzura, ariko igiciro cyayo kiri hejuru cyane; ikarito ry’umuyoboro w’impeta ryabanje gutegurwa kugira ngo rikemure ikibazo cy’amashanyarazi n’ikoreshwa ryayo, kandi imikorere yayo ni yoroshye, ariko imiterere yayo ni yoroshye, ingano ni nto, kandi igiciro ni gito cyane. Vuba aha, imirimo yakomeje kwaguka, cyane cyane ko ingano yayo nto yoroshye kuyishyiramo muri "agasanduku gahindura", bityo ifite iterambere ryiza cyane; ubu Itsinda rikuru rya Ring ntabwo rikoreshwa gusa nk’akabati ko gukurura abantu, ahubwo rishobora no gukoreshwa nk’akabati ko gukurura abantu no gukurura abantu mu kabati, akabati ko gupima, akabati ka PT.
Kubwibyo rero, mu buryo bw'umwihariko, niba ibyo byombi bishobora guhindurwa, bitewe n'imikorere n'imikorere y'ibicuruzwa by'inganda zitandukanye, ntabwo byoroshye kuvuga. Ku bijyanye no kugabanya ikiguzi, akabati k'urusobe rw'ingufu gafite ibyiza bimwe na bimwe. Hamwe n'iterambere ry'ikoranabuhanga ry'ingufu nini z'ingufu, ikoreshwa ry'agace k'ingufu nini z'ingufu n'akabati ko hagati rishobora guhurirana inshuro nyinshi. Ariko muri sisitemu yo gukwirakwiza ingufu nyinshi ifite umuvuduko munini uri hejuru ya 1250A, akabati k'ingufu nini z'ingufu ntishobora gusimbura akabati ko hagati.
