Amandla ayingozi amele ingozi ekufuneka ilawulwe

Ukuze kuhambelane neemfuno ze-1910.147, imithombo yamandla enobungozi efana nombane, umoya, i-hydraulic, i-chemical, kunye namandla obushushu kufuneka yahlulwe ngokufanelekileyo ukuya kuthi ga kwi-zero power kusetyenziswa ulandelelwano lwamanyathelo okuvala abhalwe yinkqubo yokuvala. La mandla anobungozi angentla amele ingozi ekufuneka ilawulwe ukuthintela intshukumo yoomatshini ngokuveliswa kombane okanye uxinzelelo olushiyekileyo ngexesha lenkonzo nokugcinwa. Nangona kunjalo, iingozi ezinxulumene nombane nazo zizisa ingxaki enzima yokukhusela - umbane ngokwawo. Akukhona nje kuphela ukuba kukho ingozi yombane ngendlela yokuvelisa umbane obonelela ngentshukumo yoomatshini, kodwa umbane ngokwawo kufuneka ulawulwe kwaye wahlulwe kwiindawo ezahlukeneyo zombane ezifana neephaneli zokukhupha umbane, ii-circuit breakers, ii-MCC switch panels kunye neepaneli ze-circuit breaker. Kukho ubudlelwane obubalulekileyo phakathi kokuvala umbane kunye nokhuseleko lombane. Ii-interlocks ziyimfuneko kwaye zisetyenziswa njengendlela yokulawula ukuqinisekisa ukhuseleko lwabasebenzi, kwaye ngaphambi kokulungisa okanye ukugcina ii-switchboards, iindlela zokusebenza zokhuseleko lombane kufuneka zilandelwe kwaye zilandelwe. Xa ukufakwa kombane kuvuliwe ukwenza umsebenzi, ubudlelwane phakathi koosombane abafanelekileyo kunye nabasebenzi abagunyazisiweyo ukuba bavale umbane buhamba ngendlela efanayo, kodwa kwicala elahlukileyo. Kulapho umsebenzi womnini-layisenisi uphela khona kwaye kuqala ingcali yombane efanelekileyo. Ukuvimba yindlela yokwahlula amandla anobungozi kumatshini ukuthintela ukuhamba kwezinto ezibalulekileyo kunye nokuhamba kwamandla anobungozi (umz. umoya, iikhemikhali, amanzi). Ukwahlula amandla anobungozi afana nomxhuzulane, imithombo yoxinzelelo kunye nobushushu nako kudlala indima ebalulekileyo njengoko kuchongwa njengamandla anobungozi kwizixhobo. Ukuqinisekisa ukwahlulwa kwale mithombo yamandla anobungozi,ukutshixelwa ngaphandleKufuneka kulandelwe iinkqubo zezixhobo ezithile. Ukuchongwa nokuvalelwa kwezi mithombo zamandla ziyingozi kunokwenziwa ngabasebenzi abagunyazisiweyo abaqeqeshwe ngumbutho.
