Yuav ua li cas xaim cable txhaum tester
Kev siv hluav taws xob yog ib qho tseem ceeb heev thaum siv cov khoom siv hluav taws xob cable. Ua ntej, koj yuav tsum xyuas kom meej tias tus tester qhov chaw nres nkoj yog qhov qub, xws li kuaj xyuas cov teeb meem xeb lossis kev laus. Yog tias qhov chaw nres nkoj xaim tsis raug, nws raug nquahu kom hloov cov kab hluav taws xob hauv lub sijhawm.
Cov txheej txheem kev txuas tshwj xeeb yog raws li hauv qab no:
Tam sim no sampling, DC tam sim no sampling xeem thaiv kab; Txoj kev no yog siv los kuaj qhov siab tiv thaiv qhov deb ntawm lub cable. Nws sau cov teeb liab tam sim no waveform xav rov qab thiab tawm hauv cable los ntawm kev ua txhaum mem tes thaum muaj kev cuam tshuam. Nws yuav tsum tau muab sau tseg tias "DC tam sim no sampling" tsuas yog siv tau rau flashover faults.
Ntau tus mem tes, DC ntau hom mem tes kuaj thaiv kab hluav taws xob: Txoj kev no kuj yog siv los ntsuas qhov siab tiv thaiv qhov deb ntawm lub cable. Txawm li cas los xij, nws tuaj yeem sib piv qhov tsis sib thooj waveform ntawm hauv-theem txhaum nrog kev tawg waveform hauv tib lub vijtsam.
