Tus nqi tsim nyog rau lub ntiaj teb tiv thaiv ntsuas nrog Megger lossis lub ntiaj teb tiv thaiv ntsuas nyob ntawm ntau yam,
suav nrog cov ntawv thov tshwj xeeb, hom kev teeb tsa, thiab cov qauv tsim lossis cov cai tswj hwm kev nyab xeeb hluav taws xob.
Nov yog qee cov lus qhia dav dav, tab sis nws yog ib qho tseem ceeb uas yuav tsum tau xa mus rau cov qauv siv los yog sab laj nrog tus kws tshaj lij
rau cov kev xav tau meej:
Cov lus qhia dav dav:
Chaw nyob thiab kev lag luam installation:
Rau kev teeb tsa hauv tsev thiab kev lag luam, qhov kev lees paub rau lub ntiaj teb kev tiv thaiv yuav nyob nruab nrab ntawm 1 ohm thiab 5 ohms. Cov no
Cov txiaj ntsig feem ntau yog siv los ua cov lus qhia rau kev nyab xeeb hauv av.
Industrial thiab Sensitive Environments:
Hauv cov chaw tsim khoom, cov chaw khaws ntaub ntawv, lossis lwm qhov chaw uas muaj cov khoom siv hluav taws xob muaj txiaj ntsig, lub ntiaj teb tiv thaiv qis dua
tej zaum yuav raug teev tseg. Cov nqi qis dua 1 ohm tuaj yeem raug tsom los xyuas kom muaj av zoo thiab txo qis kev pheej hmoo ntawm hluav taws xob
cuam tshuam.
High Voltage lossis Critical Systems:
Hauv kev teeb tsa high-voltage lossis cov tshuab tseem ceeb, cov kev xav tau nruj dua tuaj yeem nyob hauv qhov chaw. Lub ntiaj teb kuj muaj nuj nqis hauv qab 1
ohm lossis txawm tias qis dua 0.5 ohms yuav raug teev kom ntseeg tau tias muaj kev cuam tshuam tam sim no thiab txhim khu kev qha hauv av.
Standards thiab Regulations:
National thiab International Standards:
Lub ntiaj teb cov kev cai tiv thaiv feem ntau txhais los ntawm lub teb chaws thiab thoob ntiaj teb cov qauv. Piv txwv li, International
Electrotechnical Commission (IEC) thiab Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob thiab Hluav Taws Xob (IEEE) muab cov qauv ntsig txog
hluav taws xob installation thiab grounding.
Local Electrical Codes:
Cov lej hluav taws xob hauv zos thiab cov kev cai yuav qhia txog qhov kev lees paub hauv lub ntiaj teb raws li kev xav hauv cheeb tsam.
Kev ua raws li cov cai no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab ua tau raws li kev cai lij choj.
Site-Specific Requirements:
Qee qhov kev teeb tsa yuav muaj qhov tshwj xeeb ntawm qhov chaw raws li cov yam ntxwv xws li av tiv thaiv, ib puag ncig, thiab
cov yam ntxwv ntawm lub tshuab hluav taws xob. Cov kev ntsuam xyuas tshwj xeeb hauv tsev kawm ntawv yuav tsim nyog rau cov xwm txheej no.
Kev txiav txim siab ntxiv:
Zaus ntawm Kev Xeem:
Qhov zaus ntawm kev ntsuas lub ntiaj teb kuj tseem tuaj yeem cuam tshuam cov txiaj ntsig tau. Kev kuaj tsis tu ncua yog qhov tseem ceeb los xyuas kom meej qhov
tsis tu ncua kev ncaj ncees ntawm grounding system.
Khoom Specifications:
Cov neeg tsim khoom ntawm cov khoom siv hluav taws xob tuaj yeem muab cov lus qhia tshwj xeeb hais txog qhov tsim nyog lub ntiaj teb tiv thaiv qhov tseem ceeb rau lawv
cov khoom.
Ib txwm xa mus rau qhov tseeb version ntawm cov qauv thiab cov cai hauv koj cheeb tsam kom raug thiab hloov tshiab
cov ntaub ntawv. Tsis tas li ntawd, nws raug nquahu kom sab laj nrog tus kws tshaj lij hluav taws xob tsim nyog lossis tus kws tshaj lij paub txog hauv zos
cov kev cai rau kev taw qhia tshwj xeeb ntawm kev lees txais lub ntiaj teb qhov tseem ceeb hauv koj daim ntawv thov tshwj xeeb.
