Usetyenziso lwemeko yogcino lwamandla kwicala legridi
Iimpawu zendlela yokugcina amandla egridi yamandla
Imodyuli enkulu ejolise ekuphuculeni ukuhlanganiswa kwenkqubo ikulungele ukuthutha, ukufakwa kunye nokugcinwa.
Iibhalansi ezininzi ziqinisekisa ukuhambelana kwebhetri.
Isebenza ukutshintshwa kwencopho, ukugcwaliswa kwentlambo kunye nolawulo lokumodareyitha rhoqo kwigridi yamandla.
Uyilo oluhambelanayo lwemodyuli lulungele ukulawula kunye nokwandiswa.
Ukuchasana kwangaphakathi kwesiseko sebhetri kunokujongwa ngexesha langempela, imeko yebhetri inokubonwa, kwaye impazamo yenkqubo inokufumaneka ngokuchanekileyo.
