Umvikeli Ovala Kabusha Ozenzakalelayo We-Voltage Engaphezu/Ngaphansi Nangaphezu Kwamanje
Kuyisivikelo esihlakaniphe esibanzi esihlanganisa ukuvikelwa kwe-voltage engaphezu kwamandla, ukuvikela ngaphansi kwe-voltage, nokuvikela kwamanje. Uma amaphutha afana ne-over-voltage, under-voltage, noma over-current kwenzeka kusekethe, lo mkhiqizo unganqamula ukunikezwa kwamandla khona manjalo ukuvimbela okokusebenza kukagesi ukuthi kungashi. Uma umjikelezo ubuyela kokujwayelekile, umvikeli uzobuyisela ngokuzenzakalelayo ukunikezwa kwamandla.
Ivelu ye-over-voltage, i-under-voltage value, kanye nevelu yamanje kakhulu yalo mkhiqizo konke kungasethwa ngesandla, futhi imingcele ehambisanayo ingalungiswa ngokuya ngezimo zangempela zasendaweni. Isetshenziswa kakhulu ezimeni ezifana nemizi, izitolo ezinkulu, izikole kanye nezimboni.
