I-1, inani lonikezelo lwamandla lihlukile
Unikezelo lwamandla esekethe ephindwe kabini luthetha ukuba kukho iisekethe ezimbini zobonelelo lwamandla kumthwalo othile.Unikezelo lwamandla luqhagamshelwe kwiiswitshi ezahlukeneyo zesikhululo sokuhanjiswa kwamandla aphezulu.Ngexesha lokusebenza okuqhelekileyo, umbane omnye unikezelwa kwaye omnye ukwimeko yokulinda.Xa unikezelo lwamandla oluphambili lusilela, iukutshintsha okuzenzekelayoisixhobo kwicala lomsebenzisi siya kutshintsha unikezelo lwamandla ukuqinisekisa unikezelo lwamandla olungaphazamisekiyo lomthwalo.
Amandla aphindwe kabiniunikezelo lubhekiselele kwinto yokuba unikezelo lwamandla amabini luvela kwizitishi ezahlukeneyo (okanye kwizitishi zokusasaza), ukuze unikezelo lwamandla amabini lungaphulukana nombane ngaxeshanye.Le ndlela isetyenziswa ngokubanzi kubonelelo lombane kubasebenzisi ababaluleke ngakumbi, abanje ngezikhululo zeenqwelomoya, izikhululo zikaloliwe, izibhedlele, njl.njl. (ezi ndawo zingasentla zikwanazo nomthamo wazo wokuvelisa umbane).
2. Iindlela zokusebenza ezahlukeneyo
Le loop kwi-dual circuit ibhekiselele kwiluphu ephuma kwisitishi esingaphantsi sommandla.Amandla amabiniimithombo izimele enye kwenye.Xa umthombo wamandla omnye ucinyiwe, umthombo wamandla wesibini awuyi kunqunyulwa ngaxeshanye, onokuhlangabezana nonikezelo lwamandla lomthwalo wokuqala nowesibini.Isekethe ephindwe kabini ibhekisa ngokubanzi kwisiphelo, xa umgca omnye usilela kwaye enye isekethe yokulinda ifakwa ekusebenzeni ukubonelela umbane kwisixhobo.
3. Iipropati ezahlukeneyo
Unikezelo lwamandla esekethe ephindwe kabini lubhekisa kwizitishi ezibini okanye isitishi esingaphantsi kwesibini esiphuma kumbane wemigca emibini efanayo.
Unikezelo lwamandla kabini, kunjalo, ukusuka kunikezelo lwamandla amabini (indalo eyahlukileyo), imigca yesondlo, ngokuqinisekileyo, zimbini;Ukuba uthetha ngonikezelo lwamandla, okounikezelo lwamandla amabini.
