KvA yog thawj lub npe ntawm KiloVolt Ampere, uas yog ib chav tsev siv los sawv cev qhov loj ntawm lub zog pom hauv kev hloov tam sim no. 1kvA yog sib npaug rau qhov tam sim no ntawm 1000V voltage multiplied los ntawm 1A, 1kvA multiplied los ntawm 1000 yog sib npaug rau 1MVA, thiab 1kva muab faib los ntawm 1000 yog sib npaug rau 1VA. Nws tuaj yeem pom tau tias cov chav sib txawv tuaj yeem hloov pauv tau, thiab kev hloov pauv yog raws li qhov ntau txhiab system. Cov hauv qab no yog kev sib raug zoo ntawm kev hloov dua siab tshiab:
1vA * 1000=1kvA;
1kvA * 1000=1MvA;
1kvA * 1000=1000kvA=1MvA
Kev sib raug zoo ntawm kV thiab KVA
KV yog chav tsev ntawm qhov hluav taws xob, tseem hu ua kilovolt. High voltage yuav qhia tau nyob rau hauv kilovolts, thaum uas tsis muaj voltage yuav qhia tau hais tias nyob rau hauv millivolts mV los yog me me microvolts μ V yog chav tsev ntawm kev ntsuas, thiab kV kuj yog qhov ntsuas ntawm voltage. Nyob rau hauv lub hwj chim system, kV yog uniformly siv los piav txog qhov voltage theem ntawm lub system, xws li 110kV system, 220kV system, thiab lwm yam. 1kV yog sib npaug rau 1000V, yog li nyob rau hauv lub chav tsev conversion txheej txheem, lub txhiab system kuj siv. Cov hauv qab no yog kev sib raug zoo ntawm kV raws li chav tsev:
1kV (1000V) =1000V
1 volt (V) =1000 millivolts (mV)
1 volt (V) =1000 millivolts (mv) =1000000 microvolts (μ v), tuaj yeem sau ua 10 ^ 6
