0 Imipu yokutshaja isithuthi sombane sisebenza njengezixhobo ezibalulekileyo zokunika amandla izithuthi zombane. Le mipu isebenza njengekhonkco eliphakathi phakathi kweziseko ezingundoqo zokutshaja kunye nebhetri egcwalisekayo yesithuthi sombane. Ukuqinisekisa uxhulumaniso olungaguquguqukiyo noluthembekileyo phakathi kwemfumba yokutshaja kunye nompu, imigangatho enyanzelekileyo ibekwe ngurhulumente, ibophelela bonke abavelisi beemfumba ezihlawulisayo kunye nabavelisi bezithuthi zombane ukuba bathobele ezi nkcukacha.
Umpu otshajayo wahlulahlulwe waba 7 joints for AC piles kunye 9 joints for DC iimfumba. Iqela ngalinye libonisa umthombo wamandla owahlukileyo okanye umqondiso wolawulo, kunye nemimiselo ethile echazwe kwimigangatho yesizwe.
Embindini wemoto ephathwayo etshaja umpu kukho ibhokisi yokulawula, into ebonakala ngathi ayibonakali itekhnoloji yezindlu. Ngaphakathi kule bhokisi yolawulo kukho izinto ezininzi ezibotshelelwe kwilungelo elilodwa lomenzi wechiza, iqaqambisa ukubaluleka kwayo kwindlela yokutshaja.
