1, Ndeupi mutsauko uripo pakati pekudonha kwazvino kuyerwa neiyo stand voltage bvunzo uye bvunzo yekuvuza kwesimba?
Iyo yekumira voltage bvunzo yakaona yakawandisa ikozvino ichiyerera kuburikidza neiyo insulation system nekuda kwemaune overvoltage mamiriro.Iyo yedunhu kuvuza bvunzo inoonawo kuvuza ikozvino, asi kwete pasi peiyo yakakwira voltage yekumira voltage test, asi pasi peyakajairika kushanda voltage yemagetsi.Iyo inoyera huwandu hwezvino kuyerera kuburikidza nekumisikidzwa kweiyo inofananidzirwa muviri wemunhu kana iyo DUT ichibatidzwa uye ichimhanya.
2, Nei kudonha kwazvino kukosha kwakayerwa uchishandisa AC uye DC kutsungirira bvunzo dzevoltage dzakasiyana?
Iyo yakarasika capacitance yechinhu chakaedzwa ndicho chikonzero chikuru chemutsauko weakayerwa kukosha pakati pe AC neDC inomira bvunzo dzemagetsi.Paunenge uchiyedza ne AC, zvingave zvisingaite kubhadharisa zvizere aya akarasika capacitor uye pachave neinoenderera ikozvino ichiyerera nemavari.Paunenge uchishandisa DC kuyedza, kana iyo yakarasika capacitance pachinhu chakaedzwa ichinge yachajiswa, iyo yasara mari ndiyo chaiyo leakage ikozvino yechinhu chakaedzwa.Naizvozvo, iyo yekuvuza yazvino kukosha yakayerwa uchishandisa AC inomira voltage kuyedzwa uye DC inomira voltage kuyedzwa ichave yakasiyana.
