Kub - nruab nrab yog lub nra hluav taws xob . Qhov hluav taws xob yuav tsum nyeem txog 120 V (feem ntau 115 V txog 125 V). Koj ntsuas raws nraim 118.5 V. Nruab nrab - av yog a hluav taws xob poob (tseem hu ua IR poob) tshwm sim los ntawm kev thauj khoom tam sim no los ntawm impedance ntawm cov hlau dawb.
Tsuas yog li ntawd, vim li cas kuv thiaj li muaj qhov voltage ntawm kuv qhov nruab nrab?
Vim qhov tsis kam ntawm tooj liab nruab nrab xaim feem ntau yog ze li xoom, qhov no kuj khaws cov hluav taws xob qis. Txawm li cas los xij, yog tias cov nruab nrab hlau puas los yog muaj ib tug siab impedance txhaum zoo li ib tug corroded kev twb kev txuas, lub hluav taws xob hauv nruab nrab tuaj yeem nce mus rau theem txaus ntshai ntawm qee qhov taw qhia hauv ceg Circuit Court.
dab tsi ua rau voltage ntawm lub ntiaj teb thiab nruab nrab? Hluav taws xob tam sim no ntws los ntawm grounding los yog nruab nrab conductors, los yog txawm los ntawm ntiaj teb nws tus kheej, yuav ua rau voltage variation ntawm point mus point. Hauv qhov tseeb, txhua lub sijhawm tam sim no ntws los ntawm a nruab nrab tus thawj coj, yuav muaj ib tug hluav taws xob muaj peev xwm nrog hwm rau ntiaj teb.
Kuj nug, vim li cas kuv thiaj li muaj 120 volts ntawm kuv qhov nruab nrab?
A nruab nrab tsis txuas qhov twg tuaj yeem ua rau kev nyeem ntawv 120 volts ntawm nruab nrab rau hauv av. Qhov hluav taws xob ntws los ntawm txhua lub cuab yeej uas txuas nrog. Lub cuab yeej tsis ua haujlwm vim tsis muaj qhov ntws tam sim no.
Puas yuav tsum muaj qhov hluav taws xob ntawm qhov nruab nrab hlau?
1). Nruab nrab - rau hauv av kev sib txuas. Ib txhia nruab nrab - rau hauv av voltage yuav tsum nyob rau hauv load tej yam kev mob, feem ntau 2V los yog tsawg dua. Yog tias hluav taws xob yog xoom nrog lub load ntawm lub Circuit Court , ces check a nruab nrab -rau-hauv av kev twb kev txuas nyob rau hauv lub receptacle, seb puas los yog txhob txwm.

Dab tsi yog qhov txawv ntawm kab rau kab voltage thiab kab rau nruab nrab voltage?
Qhov voltage ntawm ob kab (piv txwv li 'L1' thiab 'L2') yog hu ua kab rau kab (los yog theem rau theem) voltage. Qhov voltage hla txhua qhov winding (piv txwv li ntawm 'L1' thiab 'N' yog hu ua kab rau nruab nrab (lossis theem voltage)
Yuav ua li cas koj pom qhov nruab nrab thiab nruab nrab ntawm daim duab peb sab?
Txhawm rau nrhiav qhov chaw nruab nrab ntawm daim duab peb sab, nws yog qhov yooj yim tshaj plaws los kos tag nrho peb qhov nruab nrab thiab nrhiav lawv qhov kev sib tshuam. Txhawm rau kos qhov nruab nrab ntawm daim duab peb sab, ua ntej nrhiav qhov nruab nrab ntawm ib sab ntawm daim duab peb sab. Kos ib kab ntu uas txuas qhov taw tes no mus rau qhov rov qab vertex
Qhov nruab nrab nruab nrab ntawm lub ntiaj teb yog dab tsi?

Koj pom qhov nruab nrab thiab nruab nrab hauv tableau li cas?
Kev sib txuas lus cov ntaub ntawv nrog Tableau los ntawm Ben Jones Qhov nruab nrab (lossis nruab nrab) yog txiav txim siab los ntawm kev suav tag nrho cov txiaj ntsig hauv cov ntaub ntawv teev thiab faib los ntawm tus lej ntawm qhov tseem ceeb. Qhov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teev nyob rau hauv uas qhov tseem ceeb tau muab tso rau hauv kev txiav txim ntawm qhov loj
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
