Nws yog ib qho tseem ceeb los ntsuas kev tiv thaiv hluav taws xob thaum lub sij hawm tag nrho cov txheej txheem ntawm kev siv nruab nrab zaus qhov chaw vuam tshuab. Yog li cas koj ua haujlwm tiag tiag kom tsis txhob muaj kev sib tsoo hluav taws xob hauv nruab nrab zaus qhov chaw vuam tshuab? Tom ntej no, cia peb saib cov lus qhia tiv thaiv hluav taws xob rau nruab nrab zaus qhov chaw vuam tshuab:
Grounding ntaus ntawv rau lub casing ntawm nruab nrab zaus qhov chaw vuam tshuab. Lub hom phiaj ntawm cov cuab yeej siv hauv av yog kom tsis txhob muaj kev sib cuag nrog lub casing thiab kev puas tsuaj rau cov khoom siv hluav taws xob. Hauv txhua qhov xwm txheej, nws yog qhov tseem ceeb. Grounding tuaj yeem siv dav rau cov khoom siv hauv av, xws li cov kav dej, cov khoom siv hlau txhim khu kev qha nrog cov khoom siv hauv av, thiab lwm yam.
Txawm li cas los xij, nws raug txwv tsis pub siv cov khoom siv hluav taws xob ua cov khoom siv hluav taws xob ua cov khoom siv hauv av. Yog hais tias, ntawm chav kawm, lub resistor ntawm lub grounding ntaus ntawv tshaj 4 ω, Siv phau ntawv grounding pab kiag li lawm, txwv tsis pub nws yog heev yuav ua rau muaj kev nyab xeeb xwm txheej los yog txawm hluav taws kub. Yog tias koj xav txav lub tshuab vuam, koj yuav tsum tau txiav lub hwj chim hloov. Nws tsis raug tso cai txav lub tshuab vuam los ntawm kev rub lub cable. Thaum muaj hluav taws xob tam sim ntawd, lub hwj chim hloov yuav tsum raug txiav tam sim ntawd kom tsis txhob muaj hluav taws xob poob.
Tsis tas li ntawd, nws yuav tsum tau hais qhia tias pawg neeg tsim kho yuav tsum tau txais kev ntsuas tsim nyog kom tsis txhob muaj hluav taws xob tawm. Nco ntsoov hnav hnab looj tes thaum hloov electrodes. Yog tias cov khaub ncaws thiab cov ris tsho tau ntub hauv hws, nws tsis raug tso cai rau lean tiv thaiv cov khoom siv hlau kom tsis txhob muaj hluav taws xob poob siab. Yog tias kho qhov nruab nrab zaus qhov chaw vuam tshuab, tshem tawm lub zog hloov pauv, thiab muaj qhov sib txawv tseem ceeb hauv lub zog hloov. Ua ntej pib txij nkawm, siv tus cwj mem hluav taws xob los xyuas kom ntseeg tau tias qhov hloov hluav taws xob tau raug txiav tawm.
