Incazelo emfushane:

I-relay yokuvikela i-voltage isebenzisa iprosesa yesivinini esikhulu nenamandla aphansi

njengengqikithi yayo. Uma umugqa wokunikezwa kwamandla une-voltage ephezulu, i-under-voltage

, noma ukwehluleka kwesigaba, ukuhlanekezela kwesigaba, i-relay izonqamula isekethe ngokushesha

futhi ngokuphephile ukugwema izingozi ezibangelwa ugesi ongavamile othunyelwa ku

umshini wokugcina. Lapho i-voltage ibuyela enanini elijwayelekile,

i-relay izovula isekethe ngokuzenzakalelayo ukuqinisekisa ukusebenza okuvamile

yemishini kagesi yokugcina ngaphansi kwezimo ezinganakwa
