Imashini yo gukurura ibintu ifite amavuta yuzuye ahantu habiriikoreshwa cyane cyane mu guhindura agasanduku k’Abanyamerika ko mu bwoko bwa terminal, hamwe n’uburyo bwo gukora bwa spring, ni switch y’ibice bitatu yo kurangiza igikorwa cyo gufunga no guhagarika imizigo.
Ku bw'ibyoswitch yo gushyira imizigo ifite imyanya ibiriishobora kandi kuba igizwe na sisitemu yo guhinduranya ubwoko bw'impeta kuri sisitemu yo gukwirakwiza ubwoko bw'impeta,switch y'imyanya ibiriimiterere: kuri, kuzimya. Igipimo cya 10kV gishobora gukoreshwa mu mishinga y'ingufu z'umuyaga mu gukoresha transfoma.
Mbere yo gukoresha transformateur yumisha.
