Inzuzo yesistimu yamandla elanga exhunywe kugridi ukuthi ilula futhi inokwethenjelwa.Abasebenzisi abadingi izinto ezengeziwe zokugcina amandla, futhi bangasebenzisa ngokugcwele amandla elanga ukuze bajove amandla kagesi kugridi, banciphise ukumosheka kwamandla.Ukuthola amandla kagesi kugridi kuqinisekisa ukutholakala kwamandla kagesi okuzinzile.Ngaphezu kwalokho, ngokusebenza kwezinhlelo zamandla elanga axhunywe kugridi, ukukhishwa kwekhabhoni nakho kungancishiswa, okubaluleke kakhulu ekuvikelweni kwemvelo.
