Inkcazo emfutshane:

I-relay yokukhusela i-voltage isebenzisa iprosesa yesantya esiphezulu nenamandla aphantsi njengesiseko sayo.

Xa umgca wombane une-over-voltage, i-under-voltage, okanye i-phase failure,

umva wesigaba, i-relay iya kuyinqumla isekethe ngokukhawuleza nangokukhuselekileyo ukuthintela iingozi

okubangelwa yi-voltage engaqhelekanga ethunyelwa kwisixhobo se-terminal. Xa i-voltage

ibuyela kwixabiso eliqhelekileyo, i-relay iya kuvula isekethe ngokuzenzekelayo ukuqinisekisa

ukusebenza okuqhelekileyo kwezixhobo zombane zesiphelo phantsi kweemeko ezingajongwanga.
