Surge voltages tshwm sim los ntawm tej yam ntuj tso xob laim los yog man-made switching transients yog ib tug heev tshwm sim thiab ib txwm tshwm sim. IEC/EN 61000-4-5 tau qhia txog tus qauv overvoltage rau hauv daim phiaj hluav taws xob, uas piav qhia txog kev ntsuas thiab ntsuas kev tiv thaiv kev tiv thaiv los ntawm overcurrent lossis overvoltage. Daim duab hluav taws xob yooj yim ntawm qhov surge (1.2/50μs 8/20μs ua ke nthwv dej) lub tshuab hluav taws xob tau qhia raws li hauv qab no.
Qhov piv ntawm peak qhib-circuit tso zis voltage rau ncov luv luv-circuit tam sim no ntawm tib cov zis
qhov chaw nres nkoj ntawm lub tshuab hluav taws xob sib xyaw ua ke yuav tsum raug suav tias yog qhov ua tau zoo tso tawm impedance.
Rau lub tshuab hluav taws xob no, qhov piv txwv txhais tau tias muaj txiaj ntsig zoo impedance ntawm 2 Ω.
Kev sib raug zoo ntawm peak qhib-circuit voltage thiab ncov luv-circuit tam sim no
Waveform ntawm qhib-circuit voltage (1,2/50 µs) ntawm qhov tso zis ntawm lub tshuab hluav taws xob tsis muaj CDN txuas
Waveform ntawm luv-circuit tam sim no (8/20 µs) ntawm cov zisntawm lub tshuab hluav taws xob uas tsis muaj CDN txuas
