Yuav ua li cas tseem ceeb xeem yuav tsum tau ua rau ntawm kev hloov pauv thaum ua haujlwm?
Txhawm rau ua haujlwm ruaj khov ntawm cov hloov pauv, cov kev ntsuas hauv qab no yuav tsum yog ua tsis tu ncua:
(1) Kuaj Kub Kub.Lub Upper roj kub yog qhov taw qhia tseem ceeb rau kev ntsuas qhov xwm txheej ntawm cov hloov pauv. Nws cov kev txwv sab sauv yuav tsum tsis pub tshaj 85 degree, uas yog, qhov chaw kub yuav tsum tsis pub tshaj 55 degree. Cov hloov hluav taws xob feem ntau yog nruab nrog cov khoom ntsuas kub tshwj xeeb los saib xyuas qhov ntsuas no.
(2) Kev ntsuas kev ntsuas.Txhawm rau kom siv tau tag nrho cov hloov pauv thiab txo cov hluav taws xob tsis muaj zog, nws lub zog muaj peev xwm yuav tsum ntsuas thaum lub caij nyoog siv hluav taws xob ntawm txhua lub caij. Kev ntsuas tuaj yeem nqa tawm ncaj qha siv cov ammeter clampeter. Lub hom phiaj tam sim no tus nqi yuav tsum tau tswj tsis pub dhau ntawm thaj tsam ntawm 70-80% ntawm qhov rated tam sim no ntawm lub transformer. Tshaj dhau qhov no qhia tawm ntau dhau thiab xav tau hloov kho nyob rau lub sijhawm.
 

(3) voltage ntsuas.Cov kev cai tsa cov kev cai lij choj uas lub voltage kev sib txawv ntau yuav tsum nyob hauv ± 5% ntawm cov ntsuas hluav taws xob. Yog tias nws ntau tshaj qhov no, nws yuav tsum tau hloov kho los ntawm tus kais kom ntseeg tau tias cov voltage ntsib cov cai. Feem ntau, cov theem nrab chev kawg voltage thiab kawg tus neeg siv kawg voltage yog ntsuas cais nrog voltmeter.
(4) rwb thaiv tsev tiv thaiv kev ntsuas.Txhawm rau tiv thaiv rwb thaiv kev laus thiab xwm txheej, lub rwb thaiv tsev tsis kam ntawm cov transformer yuav tsum tau ntsuas tsis tu ncua. Ua ntej kev ntsuas, tus hloov pauv yuav tsum nres thiab lub rwb thaiv tsev tsis kam nqi yuav tsum tau ntsuas nrog tus manohmeter, uas yuav tsum tsis pub tsawg tshaj 70% ntawm kev ntsuas tus nqi dhau los. Rau cov qes-voltage coils, maubhmeter nrog kev ntsuas hluav taws xob ntawm 500 volts tuaj yeem siv rau kev ntsuas.
