AniKhabhinethi yokusabalalisa kagesiiyingxenye yesistimu kagesi umsebenzi wayo ukusabalalisa amandla kagesi. Kufaka phakathi amathuluzi okusabalalisa, ukuvikela, ukulinganisa, ukulawula kanye namasignali. Ibhokisi lokusabalalisa ugesi nalo liqukethe izintambo, izinhlobo ezahlukene ze-insulation, nezingxenye zokusekela.
I-transformer yekhabhinethi yokusabalalisa amandla ingenye yezinto ezibalulekile ohlelweni lokuphakelwa kukagesi nokusabalalisa amabhizinisi ezimboni nezimayini kanye nezakhiwo zomphakathi. Yehlisa i-voltage yenethiwekhi engu-10(6)kV noma engu-35kV iye ku-230/400V wamabhasi kagesi asetshenziswa abasebenzisi. Lolu hlobo lomkhiqizo lufanele i-AC 50(60)Hz, umthamo olinganiselwe ophezulu wezigaba ezintathu ongu-2500kVA(umthamo olinganiselwe wesigaba esisodwa esingu-833kVA, ngokuvamile awunconywa ukusebenzisa isiguquli sesigaba esisodwa), ungasetshenziswa endlini (ngaphandle) , umthamo we-315kVA nangaphansi ungafakwa endongeni, izinga lokushisa elizungezile alikho ngaphezu kuka-40 ℃, hhayi ngaphansi kuka -25 ℃, Ukushisa okuphezulu kwansuku zonke kwansuku zonke kungu-30 ℃, izinga lokushisa eliphakeme lonyaka liyi-20 ℃, umswakama ohlobene awukho ngaphezu kuka-90% (izinga lokushisa le-ambient lingama-25 ℃), futhi ukuphakama akukho ngaphezu kwe-1000m.
