Lapho amandla enkambu ye-voltage esetshenzisiwe emshinini kagesi anele ukubangela ukukhishwa endaweni yengxenye ye-insulating, kodwa isenzakalo sokukhipha ukuthi akukho siteshi sokukhipha esinqunyiwe esakhiwe endaweni yokukhishwa kubizwa ngokuthi ukukhishwa okuyingxenye.
I-HV HIPOT GDJF-2007 Digital Discharge Analyzer
Umhloli wokukhipha uketshezi oluyingxenye lunomtshina wokukhipha ingxenye yedijithali esebenzisa isimiso sendlela yamanje ye-pulse:
Indlela yamanje ye-pulse isho ukuthi uma ukukhishwa kwengxenye kwenzeka, iziphetho ezimbili zesampula Cx zenza ukuguqulwa kwe-voltage esheshayo Δu.Kulo mzuzu, uma i-Ck kagesi ihlanganiswe ne-impedance Zd, kuzokwenziwa i-pulse current kumjikelezo, futhi i-pulse current izokwenziwa ngokusebenzisa i-impedance yokuthola.Ulwazi lwe-pulse voltage luyatholwa, luyakhuliswa futhi luyaboniswa, futhi amanye amapharamitha ayisisekelo okukhipha ingxenye (ikakhulukazi ubuningi bokukhipha q) kunganqunywa.
Kufanele kuphawulwe lapha ukuthi ingxenye yangempela yokukhishwa ngaphakathi komkhiqizo wokuhlola ayikwazi ukulinganiswa.Ngenxa yokuthi indlela yokudlulisela kanye nesiqondiso se-pulse yokukhipha ingxenye ngaphakathi komkhiqizo wokuhlola kuyinkimbinkimbi kakhulu, sidinga kuphela ukusebenzisa indlela yokuqhathanisa ukuze sithole ukubukeka okubonakalayo komkhiqizo wokuhlola.Emalini yokukhipha ugesi, okungukuthi, faka inani elithile likagesi kuzo zombili iziphetho zesampula yokuhlola ngaphambi kokuhlolwa, lungisa ukukhuliswa ukuze umise isikali, bese uqhathanisa ingxenye ye-pulse yokukhipha ngaphakathi kwesampula yokuhlola etholwe ngaphansi kwesilinganiso sangempela. I-voltage enesilinganiso, ukuze kutholwe Imali esobala yokukhipha into yokuhlola.
Umtshina wokukhipha ingxenye yedijithali uqinisekisa ukwethembeka kwedatha etholiwe ngokucubungula isignali yedijithali, ukuhlunga okuguquguqukayo nezinye izindlela zokucubungula isignali yokuphazamiseka.
