1) Qhov voltage ntawm lub Circuit Court nyob rau hauv kev ntsuam xyuas yuav tsum qis dua qhov ntsuas voltage ntawm lub ntsuas clamp
(2) Thaum ntsuas qhov tam sim no ntawm cov kab hluav taws xob siab, hnav cov hnab looj tes insulating, hnav cov khau insulating, thiab sawv ntawm cov ntaub qhwv insulating.
(3) Lub puab tsaig yuav tsum raug kaw kom nruj thiab qhov ntau yam tsis tuaj yeem hloov pauv thaum muaj hluav taws xob. Kev ntsuas Clamp-on ammeters tau muab faib ua hom hluav taws xob siab thiab tsis tshua muaj hluav taws xob, uas yog siv los ntsuas qhov tam sim no hauv kab yam tsis muaj kev cuam tshuam cov kab. Nws yog siv raws li nram no:
(1) Thaum siv lub ntsuas hluav taws xob high-voltage clamp, xyuam xim rau qib voltage ntawm lub clamp-hom ammeter, thiab nws yog nruj me ntsis txwv tsis pub siv lub ntsuas hluav taws xob tsawg-voltage clamp-type meter los ntsuas qhov tam sim no ntawm lub voj voog high-voltage. . Thaum ntsuas nrog high-voltage clamp meter, nws yuav tsum tau ua los ntawm ob tug neeg. Cov neeg ua haujlwm tsis ua haujlwm yuav tsum tau sau rau hauv daim ntawv ua haujlwm thib ob. Thaum ntsuas, lawv yuav tsum hnav cov hnab looj tes insulating, sawv ntawm cov ntaub qhwv insulating, thiab yuav tsum tsis txhob kov lwm yam khoom siv los tiv thaiv luv luv los yog hauv av.
(2) Thaum saib xyuas lub sijhawm saib, yuav tsum tau them nyiaj tshwj xeeb rau kev tswj kom muaj kev nyab xeeb ntawm lub taub hau thiab qhov chaw nyob. Qhov kev ncua deb ntawm ib feem ntawm tib neeg lub cev thiab lub cev nyob yuav tsum tsis txhob tsawg tshaj li qhov ntev ntawm lub clamp meter.
(3) Thaum ntsuas ntawm lub high-voltage Circuit Court, nws yog txwv tsis pub siv ib tug hlau mus txuas rau lwm 'meter' los ntawm lub clamp-hom ammeter los ntsuas. Thaum ntsuas qhov tam sim no ntawm txhua theem ntawm high-voltage cable, qhov kev ncua deb ntawm lub taub hau cable yuav tsum ntau tshaj 300mm, thiab cov rwb thaiv tsev yuav tsum zoo.
(4) Thaum ntsuas qhov tam sim no ntawm qhov hluav taws xob qis fusible fuses lossis kab rov tav txheej txheem qis-voltage busbars, txhua theem ntawm fusible fuses lossis busbars yuav tsum tau tiv thaiv thiab cais nrog cov ntaub ntawv insulating ua ntej ntsuas kom tsis txhob luv luv ntawm cov theem. (5) Kev ntsuas yog nruj me ntsis txwv tsis pub thaum ib theem ntawm cable yog grounded. Tiv thaiv kev nyab xeeb ntawm tus kheej los ntawm kev puas tsuaj rau tus kheej kev nyab xeeb vim qhov tsis muaj rwb thaiv tsev ntawm lub taub hau cable thiab qhov tshwm sim ntawm kev tawg hauv av.
(6) Rub tus hloov mus rau qhov siab tshaj plaws tom qab qhov ntsuas clamp-hom ammeter tiav, kom tsis txhob muaj kev sib tsoo overcurrent hauv kev siv tom ntej; thiab nws yuav tsum tau muab cia rau hauv chav qhuav.
