Qhov hloov hluav taws xob hloov ib tus kais ntawm qhov qhuav -hom transformer tsis yog tus nqi ruaj khov. Nws nyob ntawm lub transformer tus tsim tsis, hom kais changer, thiab daim ntawv thov tshwj xeeb.
Feem ntau, tus kais hloov pauv ntawm qhov qhuav- hom transformer yog siv los kho cov khoom siv hluav taws xob hloov pauv kom hloov mus rau qhov hloov pauv hauv qhov hluav taws xob hluav taws xob lossis kom tau raws li qhov xav tau ntawm cov khoom tshwj xeeb. Qhov kev hloov pauv ntawm tus kais hloov pauv feem ntau yog qhia los ntawm cov kais dej, txhua qhov sib xws rau qhov hloov pauv tshwj xeeb. Hauv kev ua kom qhuav- hom transformer tsim, qhov kev hloov pauv ntawm tus kais hloov pauv tuaj yeem nyob hauv ± 5%. Qhov tshwj xeeb voltage hloov ib tus kais yog nyob ntawm tus transformer qhov ntsuas voltage thiab tag nrho cov kais dej. Piv txwv li, rau qhov qhuav- hom transformer nrog qhov ntsuas hluav taws xob ntawm 10kV, yog tias tus kais hloov pauv tau tsim nrog kev hloov pauv ntawm ± 5% thiab muaj 5 tus kais dej (suav nrog cov ntsuas ntsuas hluav taws xob), ces qhov hloov pauv ntawm ib tus kais yog kwv yees li 1% ntawm qhov ntsuas hluav taws xob (piv txwv li, txog 100V). Txawm li cas los xij, qhov no tsuas yog kev kwv yees ntxhib xwb, thiab qhov hloov pauv tiag tiag yuav txawv nyob ntawm tus qauv transformer, chaw tsim khoom, thiab kev tsim tshwj xeeb. Qee qhov qhuav- hom transformers tej zaum yuav muaj kev hloov kais dej ntau dua nrog cov kais dej ntau dua thiab qhov sib txawv me me ntawm ib tus kais dej; Lwm tus yuav muaj tsawg dua kais dej thiab qhov hloov pauv loj dua rau ib tus kais. Tsis tas li ntawd, kais hloov pauv hloov pauv yuav tsum xav txog yam xws li lub tshuab hloov pauv qhov kev thauj khoom, kev ruaj ntseg ntawm daim phiaj hluav taws xob, thiab seb qhov hloov kho qhov hluav taws xob puas ua tau raws li qhov yuav tsum tau ua. Yog li ntawd, hauv kev xyaum, kais hloov pauv hloov pauv rau qhuav- hom hloov pauv yuav tsum tau ua los ntawm cov neeg ua haujlwm tsim nyog los xyuas kom meej qhov kev nyab xeeb thiab kev ua tau zoo ntawm kev hloov kho. Tom qab qhov kev hloov kho, cov kev ntsuam xyuas tsim nyog thiab kev saib xyuas yuav tsum tau ua los xyuas kom meej cov txiaj ntsig thiab xyuas kom lub transformer ua haujlwm li qub.
