Kev siv txoj kev tsis ncaj ncees kom paub qhov kev sim ntawm qhov sib piv, piv txwv qhov yuam kev thiab theem kaum qhov yuam kev, thiab lwm yam.
Los ntawm kev sib piv thiab kev xeem nkag, xam tawm qhov yuam kev ntawm 80% -120% rated voltage nyob rau hauv rated load thiab txo lub nra hnyav.
Qhov loj me thiab lub teeb yuag, haum rau kev sim ntsuas ntawm Capacitance PT.
Voltage ratio test.
Tshawb xyuas cov xaim thiab txiav txim qhov tsis raug xaim, lub sijhawm no qhia "rov qab polarity" lossis "secondary open" lossis "tsis ncaj ncees piv" thiab kho tus nqi qis dua.
Test Tsis-load yuam kev nyob rau hauv 2.2KV.
Ntsuam xyuas qhov yuam kev uas tsim los ntawm thawj & theem nrab ntsuas lub nra.
Ntsuas qhov kev nkag mus rau theem nrab thiab tau txais tsis muaj qhov yuam kev hauv qab 80%, 100% thiab 120% qhov ntsuas hluav taws xob.
Ntsuas qhov yuam kev ntawm theem nrab winding 1n1a thiab 2n2a nyob rau hauv qhov ntsuas lub nra thiab qis qis qis qis qis dua 80%, 100% thiab 120% qhov ntsuas hluav taws xob, thiab ua cov nqi yuam kev.
