Puas yog nws muaj kev nyab xeeb siv kev sib nrig sib pab inductorCt pt tus yam ntxwvnyob rau nyob nruab hnub?
Tsis yog!Nws yog nruj me ntsis txwv tsis pub siv cov kev ntsuas no rau cov hloov chaw tam sim no (CTS), VTS), lossis lawv cov voj voog theem ob.
Cov laj thawj thiab cov lus qhia ntxaws ntxaws:
1.TESTER DES YUAV TSUM TAU DE HEA -} Enterization:
{{{0} ecere} Kuv yuav tsum tau thov kho tau cov hluav taws xob hluav taws xob ntau ntxiv rau qhov kev sib tsoo theem nrab kom ntsuas tau tam sim no. Qhov kev xav tau no ua tiav cov winderary ntawm tag nrho lwm cov voj voog (tiv thaiv kom rov qab, av, thiab lwm yam ntws. Nyob tsis tau raws li qhov no.
Kev kuaj ntsuas piv txwv: cuam tshuam nrog kev paub cov kev paub tam sim no / voltage mus rau sab ob sab thiab ntsuas sab hauv ib sab. Qhov no tseem yuav tsum muaj transformer los ua offline thiab cais, tsis muaj kev ua haujlwm tam sim no / voltage ntawm thawj.
Kev kuaj polarity: Feem ntau yog siv DC lossis qis {- zaus} zaus pob kom saib cov lus qhia ntawm lwm tus. Ua li no nyob rau hauv cov tshuab nyob tsis tshua muaj kev phom sij, pheej hmoo tiv thaiv kev tiv thaiv kev ua phem, khoom puas tsuaj, lossis kev ua phem (rau vts).
2.Critical phom sij ntawm kev ua haujlwm nyob:
CT nrab thib ob qhib - Circuit Court (tsis tshua muaj txaus ntshai):
Txhua qhov kev sib txuas / Disconnection rau CT theem nrab kev ncig thaum energized tuaj yeem ua rau qhib {{voj voog.
Ib qho qhib - cirrenited ct tsim cov kv ntawm kv) ntawm cov khoom siv hluav taws xob hnyav, kev rhuav tshem cov khoom siv / tiv thaiv rov qab, thiab hluav taws kub.
Thawj siab voltage intrusion (VTS):
Cov xaim tsis yog lossis kev ua haujlwm tsis yog tuaj yeem ua kom paub thawj lub siab voltage rau hauv qis {{voltage theem nrab, ua rau cov cuab yeej ua kom puas lossis siv hluav taws xob.
Av tsis muaj kev phom sij:
Nyob nrog kev ua kom muaj kev phom sij ntawm kev sib cuag sib luag, luv luv kev sib tw, lossis kev ua yuam kev hauv av.
Kev cuam tshuam nrog cov haujlwm ua haujlwm:
Txhaj cov phiajcim xeem yuav cuam tshuam kev tiv thaiv / tswj cov tshuab, ua rau:
Kev tiv thaiv regay kev npau taws: tsis tseem ceeb.
Kev tiv thaiv tsis ua haujlwm: Tsis muaj peev xwm los teb rau qhov ua txhaum tiag tiag.
Kev Ntsuas Yuam: Skewed Metered / Tswjhwm.
Ua txhaum ntawm cov lej kev nyab xeeb:
Cov kev cai nyab xeeb hluav taws xob (piv txwv li, IEEE, NFPA 70E, IEC / second /}} Enter, thiab ciam chaw kev nyab xeeb, thiab thaj tsam kev nyab xeeb, thiab thaj tsam kev nyab xeeb. Ua haujlwm ua haujlwm ua txhaum cov lis dej num.
