Amavuta-yashizwemo urutonde rwaJLS-3, 6, 10 ／ agasanduku k'ibipimo byo hejuru

Imashanyarazi ifite ingufu nyinshi zashyizwe mu gasanduku, nta metero ya watt-isaha, bita transformateur ihujwe, hamwe n'ubwoko bwa AC bwinjijwe mu mavuta yo hanze (nayo ikwiriye mu nzu).Nibikoresho bipima gupima mu buryo butaziguye ingufu zikora kandi zidasanzwe mumirongo yumuriro mwinshi.Irakoreshwa mubyiciro bitatu AC ifite inshuro 50, 60Hz;10KV, 6KV, 3KV umuyoboro wa sisitemu.Ifite ibyiza byo hejuru, gusubiramo urumuri, kwishyiriraho byoroshye no kurwanya ubujura bwamashanyarazi.Benshi mubashinzwe gutanga amashanyarazi murakaza neza.
Agasanduku k'ibyiciro bitatu-metero eshatu agasanduku kagizwe na voltage ebyiri imwe imwe ya voltage hamwe na transformateur ya none, naho ibyiciro bitatu-bine bya metero ya agasanduku kagizwe na voltage imwe yicyiciro kimwe na transfert zubu.Ikariso yashyizwe ku kibaho, kandi hejuru yacyo ifite metero ya watt- yo gupima.
