Qhov sib txawv zaus Series Resonance Test System txais cov txheej txheem uas kho qhov zaus ntawm lub hwj huam mov, ua rau lub reactor thiab kuaj capacitor tau resonance thiab HV siab tam sim no muaj los ntawm cov khoom siv kuaj. Qhov no yog ib txoj hauv kev tshiab thiab qauv tam sim no, dav siv hauv tsev thiab txawv teb chaws. Cov khoom siv tester yog tsim los ntawm cov khoom siv hluav taws xob sib txawv, kev hloov pauv siab, reactor, thiab capacitor. Lub capacitor thiab reactor ntawm cov cuab yeej kuaj sim ua ib daim ntawv ntawm kev sib txuas resonant. Ib qho hluav taws xob faib hluav taws xob yog nyob rau hauv qhov sib npaug hauv cov khoom siv ntsuas, uas yog siv los ntsuas qhov hluav taws xob resonant nws thiab raws li cov teeb liab tiv thaiv dhau-voltage. Lub zog tso zis ntau zaus los ntawm excitation transformer yog txuas mus rau ib tug series resonant circuit, muab excitation zog ntawm series resonance.
