Kev xaim ntawm cov khoom sib txawv ntawm cov khoom siv ntsuas hluav taws xob sib txawv thaum ua cov kev sim sib txawv. Niaj hnub no, cia peb ua raws li cov lus piav qhia ntawm peb cov kws tshaj lij engineers los saib cov txheej txheem thaiv ntawm cov khoom siv dav dav rau cov yam ntxwv ntawm transformer volt-ampere.
CT ratio polarity test wiring ntawm transformer volt-ampere yam ntxwv kev tester muaj nyob rau hauv daim duab.
Lus Cim 1: Nyob rau hauv lub transformer volt-ampere yam ntxwv zoo tester, vim yog cov tam sim no loj nyob rau hauv thawj sab, thov sim siv ib tug tuab thiab luv luv txuas hlau los tiv thaiv qhov tam sim no tsis tuaj yeem nce mus rau "ib zaug ntsuas tam sim no. "vim qhov tseem ceeb tshaj tus nqi xaim tsis kam.
Lus Cim 2: Thaum lub transformer volt-ampere yam ntxwv zoo tester tab tom ua qhov transformation ratio polarity test, thov disconnect lub grounding hlau ntawm CT thib ob winding ua ntej kom tsis txhob muaj kev puas tsuaj rau lub cuab yeej.
