Lub zog hluav taws xob yog ib qho kev ntsuas ntawm lub zog poob los ntawm cov kab hluav taws xob rwb thaiv tsev rau hauv av los ntawm cov dej xau tam sim no. Nws yog sib npaug rau Circuit Court tsis kam (R) faib los ntawm Circuit Court impedance (Z).
PF=W / VI or PF=(VI cosθ ) / (VI )
Lub hwj chim ntawm rwb thaiv tsev yog lub cosine ntawm lub kaum sab xis ntawm lub charger tam sim no vector thiab cov impressed voltage vector. Hauv lwm lo lus, nws yog ib qho kev ntsuas ntawm lub zog tivthaiv ntawm cov khoom siv tam sim no. Tus nqi them volt-amperes thiab cov dielectric poob hauv watts, ntawm qhov muab hluav taws xob, nce nrog cov nqi hluav taws xob raug kuaj. Txawm li cas los xij, qhov sib piv (lub zog qhov tseem ceeb) ntawm qhov them volt-amperes thiab watts-tsawg tseem zoo ib yam tsis hais txog qhov ntsuas qhov ntsuas hluav taws xob, piv txwv tias cov rwb thaiv tsev yog qhov zoo ib yam. Qhov kev sib raug zoo no tshem tawm cov txiaj ntsig ntawm qhov loj ntawm cov cuab yeej hluav taws xob hauv kev tsim "ib txwm" qhov tseem ceeb ntawm rwb thaiv tsev thiab yog li ua kom yooj yim qhov teeb meem rau cov kws ua haujlwm kuaj. Qhov tseeb, kev ntsuas fais fab yog ntau dua li "ib" kev sim. Nws yog ib tug series ntawm kev ntsuam xyuas ntawm txhua feem ntawm lub rwb thaiv tsev system. Kev ntsuas hluav taws xob hluav taws xob kuj tseem tuaj yeem ua rau hluav taws xob ntes, cua thiab roj hluav taws xob hluav taws xob, tam sim no thiab muaj peev xwm hloov pauv, capacitors, cable (500 ko taw lossis tsawg dua) thiab cov tshuab tig, xws li motors thiab generators.
Lub hom phiaj ntawm kev ntsuas hluav taws xob rwb thaiv tsev yog dab tsi?
• Txhawm rau txiav txim siab qhov dryness thiab cov khoom zoo ntawm rwb thaiv tsev. Nws feem ntau yog siv ua ke nrog rau lwm yam dryness indicators, xws li rwb thaiv tsev tsis kam thiab roj dielectric breakdown qhov tseem ceeb, los txiav txim rwb thaiv tsev dryness.
• Txhawm rau ntsuas lub zog poob vim qhov xau tam sim no los ntawm kev rwb thaiv tsev transformer.
• Txhawm rau txhawm rau ntsuas qhov ntsuas qhov hloov pauv hauv qhov hloov pauv winding rwb thaiv tsev yam ntxwv.
• Muab ib qho kev qhia tag nrho ntawm cov xwm txheej ntawm cov txheej txheem insulating.
• Txhawm rau ntsuas lub zog poob vim qhov xau tam sim no los ntawm kev rwb thaiv tsev transformer.
• Txhawm rau txhawm rau ntsuas qhov ntsuas qhov hloov pauv hauv qhov hloov pauv winding rwb thaiv tsev yam ntxwv.
• Muab ib qho kev qhia tag nrho ntawm cov xwm txheej ntawm cov txheej txheem insulating.
