Ibhokisi yokuhambisa sisixhobo esisetyenziselwa ukuhanjiswa kwamandla. Imisebenzi yayo ephambili ibandakanya oku kulandelayo:
1. Ukuhanjiswa kwamandla: Njengendawo yokuqokelela amandla kunye nokusabalalisa, ibhokisi yokusabalalisa ihambisa izibonakaliso zamandla angenayo kwizixhobo ezifuna amandla, ngaloo ndlela ifezekisa ukusabalalisa kwamandla.
2. UKhuseleko loMbane: Ibhokisi yokuhambisa ibonelela ngomthwalo ogqithisileyo,{1}}omfutshane{1}}ukhuselo, kunye nokhuseleko lokuvuza kwezixhobo zombane, ukuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo kwesixokelelwano samandla kunye nokuthintela iingozi.
3. Ummiselo wangoku: Ngaphakathi koluhlu oluchaziweyo, ibhokisi yokusabalalisa inokulungelelanisa okwangoku njengoko kuyimfuneko, inika abasebenzisi i-voltage ezinzileyo kunye nekhoyo.
4. Ulawulo lokutshintsha: Izixhobo zokulawula ukutshintshwa ngaphakathi kwebhokisi yokuhambisa zivumela ulawulo olulula kunye olukhawulezayo lwezixhobo zombane ezahlukeneyo, ziququzelele ukusebenza kwazo kunye nokucima.
5. Ulawulo lwegridi: Ibhokisi yokuhambisa ilawula igridi yamandla kwaye ilungise ngokukhawuleza iimpazamo zegridi, ukuqinisekisa ukuba izixhobo zikhuselwe emonakalweni.
6. Ukujongwa kweDatha: Ibhokisi yokusabalalisa inokuxhotyiswa ngeenzwa, iimitha zangoku kunye ne-voltage, kunye nezinye izixhobo zokubeka iliso kwimeko yokusebenza kwezixhobo zombane ngexesha langempela, ukubonelela ngenkxaso eqinile yokulungiswa kwezixhobo kunye nokugcinwa.
