Ukusasazwa kweZixhobo zoMbane ezibuNgqibo-bubungqina

Phantsi kwezikhokelo ezibekwe yimigangatho yofakelo lwezixhobo zombane ezingaqhushumba, njenge GB3836.15, imithombo yamandla yezixhobo ezinjalo inokusebenzisa i-TN, TT, kunye neenkqubo ze-IT. Ezi nkqubo kufuneka zihambelane nayo yonke imigangatho yesizwe efanelekileyo, kubandakanywa iimfuno ezithile zobonelelo lwamandla ezongezelelweyo ezichazwe kwi-GB3836.15 kunye ne-GB12476.2, ecaleni kokuphumeza amanyathelo ayimfuneko okhuseleko.

Thatha inkqubo yamandla ye-TN, umzekelo, ngakumbi ukwahluka kwe-TN-S, okubandakanya ukungathathi hlangothi okwahlukileyo (N) kunye nokukhusela (PE) abaqhubi. Kwiindawo ezinobungozi, aba baqhubi akufuneki badityaniswe okanye badityaniswe kunye. Ngethuba naluphi na utshintsho ukusuka kwi-TN-C ukuya kwiintlobo ze-TN-S, umqhubi okhuselayo kufuneka adibaniswe ne-equipotential bonding system kwiindawo ezingenabungozi. Ngaphaya koko, kwiindawo eziyingozi, ukujongwa okusebenzayo kokuvuza phakathi komgca ongathathi hlangothi kunye nomqhubi wokukhusela we-PE kubalulekile.
