Kev xaiv tus kais hloov thiab daim ntawv ceeb toom rau cov neeg siv:

1. Qhov chaw ua haujlwm thiab lub cev khoom raug sib cais thiab siv txoj kev teeb tsa yooj yim. Thov xaiv lub tshuab ua haujlwm thiab tus qauv khoom raws li koj xav tau.

2. Cov hlau txhuas thiab cov pas nrig rwb thaiv tsev ua haujlwm tau nruab rau lub kais hloov. Thov sau tseg rau hauv daim ntawv ceeb toom thiab kev txiav txim kom meej yog tias muaj qhov xav tau tshwj xeeb. Lub pas nrig rwb thaiv tsev ua haujlwm yuav tsum tau ziab nrog lub kais hloov ua ntej kev teeb tsa thiab tom qab ntawd nws tuaj yeem siv tau. Cov hlau txhuas tau qhwv nrog daim ntawv rwb thaiv tsev sab nraud. Thov sau tseg yog tias muaj qhov xav tau tshwj xeeb rau qhov tuab ntawm daim ntawv rwb thaiv tsev.

3. Yog tias tsis muaj △ hauv tus qauv yooj yim, nws yog rau kev sib txuas nruab nrab.

4. Yuav tsum muaj 20% seem seem rau qib tam sim no ntawm tus kais hloov pauv.

5. Kev xaiv ntawm qhov hloov pauv ntawm lub qhov (voltage) yuav tsum ua raws li qhov yuav tsum tau ua ntawm lub zog fais fab thiab qhov yuav tsum tau ua ntawm "kev rwb thaiv tsev tseem ceeb thiab kev rwb thaiv tsev ntev." Thov qhia meej yog tias muaj qhov xav tau tshwj xeeb.

6. Thaum txhim kho lub clamp hom tap changer, ob qho tib si tap changer thiab transformer clamp yuav tsum tau kho kom ruaj khov, txwv tsis pub lub pas nrig ua haujlwm yuav nyob rau hauv thiab tawm uas yog tshwm sim los ntawm tap changer txav mus rau hauv qab tom qab kev co.

7. Thaum lub tap changer txuas nrog lub transformer coil tapping, thov ua raws li daim ntawv lo ntawm lub tap changer. Rau lub radial kab hom tap changer, lub hauv paus hlau txhuas yuav tsum tsis txhob raug khoov los ntawm kev ntaus nws hnyav thaum lub sijhawm txuas hlau. Lub hlau txhuas yuav tsum raug khoov hauv kev dov ntsiag to. Thaum lub hlau txhuas raug khoov, lub rwb thaiv tsev ntawm lub hauv paus yuav qhia cov hlau txhuas, uas xav tau tus neeg siv los ntim nws tus kheej.

8. Tom qab ziab lub kais hloov, pls tsis txhob hloov qhov chaw ntawm lub kais tsuas yog tias nws tau roj txaus kom tsis txhob puas tsuaj. Yog tias lub tshuab ua haujlwm ntawm lub kais hloov thiab lub cev ntawm lub kais hloov sib cais, tsuas yog ziab lub cev ntawm lub kais hloov xwb.

9. Qhov txwv tsis pub siv tshuab yog teeb tsa rau hauv lub tshuab hloov pauv. Thov tsis txhob siv ntau tshaj qhov txwv thaum rub nws kom tsis txhob puas tsuaj. Thov siv kev cuam tshuam thaum rub lub iav.

10. Thaum lub sijhawm tshuaj xyuas lub hauv paus lossis kev ua haujlwm ntawm qhov chaw, yog tias xav tau kev tshem tawm lub kaw lus ua haujlwm lossis lub kaw lus kis ntawm lub kais hloov pauv, thov cim lawv ua ntej tshem tawm. Hloov cov haujlwm tom qab ua tiav kev sib dhos thiab sim DC tsis kam hloov pauv kom paub tseeb tias kev teeb tsa puas raug.
