Lub zog hloov hluav taws xob yog hom hluav taws xob hloov hluav taws xob uas tau siv los hloov hluav taws xob nruab nrab ntawm ob lossis ntau dua hluav taws xob los ntawm hluav taws xob induction. Nws yog tsim los ua haujlwm ntawm voltages high voltages thiab yog qhov tseem ceeb hauv kev kis thiab xa hluav taws xob. Lub zog hloov hluav taws xob feem ntau yog pom nyob rau hauv cov chaw sib txuas, qhov chaw uas lawv nqis tsheb sib txuas rau cov qib kom qis rau cov tsev thiab cov lag luam.
Thaum nws los txog zog meters,Lub zog hloov hluav taws xobUa si lub luag haujlwm tseem ceeb hauv kev ntsuas qhov tseeb ntawm kev noj hluav taws xob. Zog meters, tseem hu ua Watt-teev meters, yog cov cuab yeej siv me me uas ntsuas qhov ntau ntawm lub zog hluav taws xob tau siv los ntawm lub zog hluav taws xob, kev lag luam, lossis hluav taws xob ntaus nqi raws sijhawm. Cov meters no yog qhov tseem ceeb rau kev them nqi thiab rau kev saib xyuas kev siv hluav taws xob.
Feem ntau, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj kev lag luam lossis cov tsev lag luam loj, cov qib voltage tuaj yeem siab rau cov qauv hluav taws xob meters los tuav ncaj qha. Qhov no yog qhov chaw hluav taws xob hloov tuaj rau hauv kev ua si. Lawv raug siv los nqis cov siab voltage rau theem qis, tswj tau qib uas tuaj yeem ntsuas kev nyab xeeb los ntawm lub zog ntsuas. Cov txheej txheem no tsis tsuas yog tiv thaiv lub ntsuas dej los ntawm cov peev xwm kev puas tsuaj vim yog cov kev nyeem ntawv siab tab sis kuj ua kom txhua yam yog qhov tseeb.
Cov kev hloov hluav taws xob siv tau siv nrog cov hluav taws xob meters feem ntau hu ua "hloov pauv tam sim no" (CTS) thiab "Voltage Transformers" (VTS). Cov hloov pauv tam sim no tau siv los ntsuas qhov tam sim no ntws los ntawm tus thawj coj, thaum hluav taws xob hloov hluav taws xob tau siv ntsuas qhov hluav taws xob hla ntawm qhov Circuit Court. Los ntawm kev siv cov kev hloov no, hluav taws xob meters tuaj yeem xam lub zog kev siv los ntawm kev ntsuas ntsuas tam sim no thiab hluav taws xob.
Kev sib koom ua ke ntawm cov hluav taws xob hloov hluav taws xob nrog lub zog me me yog qhov tshwj xeeb tshaj yog nyob rau hauv peb-theem systems, uas yog siv tau siv hauv kev siv cov ntawv thov. Nyob rau hauv cov tshuab zoo li no, peb pawg ntawm cov dej ntws thiab voltages yuav tsum tau ntsuas ib txhij. Lub zog hloov pauv pab qhov no los ntawm kev muab ntsuas qhov tsim nyog ntawm hluav taws xob, tso cai rau lub zog ntsuas kom muaj zog ua haujlwm zoo.
Ntxiv mus, kev siv ntawmLub zog hloov hluav taws xobnyob rau hauv zog meters txhim kho kev nyab xeeb. HEEV cov kev pheej hmoo siab tuaj yeem ua rau muaj kev pheej hmoo tseem ceeb, suav nrog hluav taws xob hluav taws xob thiab hluav taws kub. Los ntawm stepping nqes lub voltage rau ib qib muaj kev nyab xeeb, ua kom muaj kev phom sij rau cov hluav taws xob kom nyab xeeb.
Hauv cov ntsiab lus, lub zog hloov hluav taws xob yog qhov tseem ceeb ntawm kev ua haujlwm ntawm lub zog me me, tshwj xeeb hauv cov ntawv thov siab voltage. Nws ua rau kev ntsuas hluav taws xob ncaj ncees los ntawm kev nce qib hluav taws xob nce qib rau cov kev tswj tau ntau. Qhov no tsis tsuas yog ua kom pom kev xa nqi thiab saib xyuas lub zog siv zog tab sis kuj ua kom muaj kev nyab xeeb hauv hluav taws xob. Kev nkag siab lub luag haujlwm ntawm cov hluav taws xob hluav taws xob hauv cov hluav taws xob me me yog qhov tseem ceeb ntawm cov khoom siv cuam tshuam nrog cov khoom siv hauv cov khoom siv hluav taws xob.
