Voltage kuchengetedza relay inoshandisa yakakwirira-kumhanya uye yakaderera-simba processor
sehwaro hwayo. Kana tambo yemagetsi ine over-voltage, under-voltage
, kana kutadza kwechikamu, phase reverse, relay ichagura dunhu nekukurumidza
uye zvakachengeteka kudzivirira tsaona dzinokonzerwa neabnormal voltage inotumirwa
iyo terminal mudziyo. Kana voltage ichidzokera kune yakajairika kukosha,
iyo relay ichabatidza dunhu otomatiki kuti ive nechokwadi chekushanda kwakajairika
yemagetsi emagetsi ekupedzisira pasi pemamiriro asina kutarisirwa
