Njengezixhobo ezingundoqo kwintsimi yokulinganisa amandla, uluhlu lokulinganisa imitha yombane lumisela ngokuthe ngqo iimeko ezisebenzayo kunye nokuthembeka kwedatha. Ukuchaza ngokwenzululwazi iiparamitha zoluhlu lwemitha ngundoqo ekuqinisekiseni umlinganiso ochanekileyo wamandla, ukuhambelana kwenkqubo, kunye nokhuseleko lomsebenzisi.
Ukususela kumbono wobugcisa, uluhlu lokulinganisa imitha yombane ngokuqhelekileyo luqulunqwe zizibonakaliso ezimbini eziphambili: "i-rated current" kunye "nobuninzi bangoku." Kwinqanaba elinye eliqhelekileyo - imitha yamandla e-elektroniki, umzekelo, umlinganiselo wangoku (umzekelo, 5A, 10A) ubonisa ixabiso lesiseko sexesha elide{6}} elizinzile lokusebenza phantsi kweemeko zokusebenza ezisemgangathweni, ngelixa ubuninzi bangoku (umzekelo, 60A, 80A) bumele ukunyamezela komthwalo wemitha ubude obufutshane{11}. Ukugqithisa eli xabiso kunokubangela ukufudumeza kwecandelo okanye ukwandisa iimpazamo zomlinganiselo. Kwizigaba ezithathu{14}}zemitha yombane wemizi-mveliso, uluhlu lomlinganiselo kufuneka luhambise iimfuno zomthwalo eziphezulu. Eminye imifuziselo ixhasa uluhlu olubanzi lomlinganiselo we-0.1A ukuya ku-200A nge-0.5S-echanekileyo kwinqanaba, kwaye inokwandiswa ukuya kuluhlu lwe-kilompere nge-shunt yangaphandle.
Iimfuno zoluhlu lweemitha zohluka kakhulu kwiimeko ezahlukeneyo zosetyenziso. Kwiimeko zokusetyenziswa kombane kwindawo yokuhlala, iimitha zivala umthamo wekhaya uwonke we-3kW ukuya kwi-10kW (ohambelana nemisinga emalunga ne-13A ukuya kuma-45A). Oku akufezekisi kuphela iimfuno zezixhobo zombane zemihla ngemihla, kodwa kukwavumela ukudityaniswa kwezixhobo zombane eziphezulu{6} ezifana nezifudumezi zomoya kunye nezifudumezi zamanzi zombane. Iimeko zoshishino kunye nezorhwebo zifuna uluhlu oluguquguqukayo oluphezulu. Ngokomzekelo, amagumbi amaziko edatha anokuthi axhotyiswe ngeemitha ezihlakaniphile kunye noluhlu lwe-200A okanye ngaphezulu ukubeka iliso kwisantya esiphezulu somthwalo wamaqela omncedisi. Kwigridi yamandla ahlaziyekayo{11}}iinkqubo eziqhagamshelweyo, iimitha kufuneka zixhase umlinganiselo we-bidirectional (isizukulwana kunye nokusetyenziswa), kwaye uyilo loluhlu kufuneka lubambe ngokuchanekileyo imisinga ukuya phambili kunye nokubuya umva.
Kubalulekile ukuqaphela ukuba ukukhetha uluhlu lweemitha alukho ngcono. Ukugqithiswa kweendlela zokulinganisa eziphezulu kunokunciphisa uvakalelo lwemitha ngexesha lomthwalo ophantsi (umzekelo, imitha ye-100A inokufumana iphutha elongezelelweyo xa ilinganisa i-5A), ngelixa uluhlu oluphantsi kakhulu lunokunyusa umngcipheko wokulayisha ngaphezulu. Iimitha ezihlakaniphile zangoku zilungelelanisa olu xinzelelo ngokusebenzisa{4}}uluhlu oluzenzekelayo lokutshintsha ubugcisa (obufana noyilo olubanzi lwe-turndown ratio). Iimodyuli zonxibelelwano zinokufaka iiprofayili zokulayisha ngexesha lokwenyani, ukunceda abasebenzisi ukuba basebenzise umbane wabo. Ukulinganisa uluhlu lomlinganiselo weemitha zombini kuyimfuno engqongqo yemigangatho yobugcisa kunye necandelo eliphambili ekuqinisekiseni ulawulo olusebenzayo lwamandla. Njengoko iinkqubo zamandla zisiba nengqondo ngakumbi, ukulungiswa koluhlu lweemitha ezichanekileyo kuya kuqhubeka kuyinkxalabo ephambili kushishino.
