Xa amandla entsimi ye-voltage esetyenzisiweyo kwisixhobo sombane kwanele ukuba kubangele ukukhutshwa kwindawo ye-insulating part, kodwa isiganeko sokukhutshwa ukuba akukho mjelo wokukhutshwa okusisigxina owenziwe kwindawo yokukhutshwa kuthiwa yi-partial discharge.
I-HV HIPOT GDJF-2007 I-Digital Discharge Analyzer
Umvavanyi wokukhuphela ngokuyinxenye unesixhobo sokukhupha i-digital partial discharge sisebenzisa umgaqo wendlela ye-pulse yangoku:
Indlela yangoku ye-pulse ithetha ukuba xa ukukhutshwa kwenxalenye kwenzeka, iziphelo ezimbini zesampulu ye-Cx zenza utshintsho lwe-voltage kwangoko Δu.Kulo mzuzu, ukuba i-Ck yombane idibaniswe ne-impedance yokufumanisa i-Zd, i-pulse yangoku ndiya kuveliswa kwisiphaluka, kwaye i-pulse yangoku iya kuveliswa nge-impedance yokufumanisa.Ulwazi lwe-pulse voltage luchongiwe, lunyusiwe kwaye lubonisiwe, kwaye ezinye iiparamitha ezisisiseko zokukhutshwa ngokuyinxenye (ubukhulu becala ubuninzi bokukhupha q) bunokumiselwa.
Kufuneka kucaciswe apha ukuba ukukhutshwa kwenxalenye yokwenene ngaphakathi kwimveliso yovavanyo ayinakulinganiswa.Ngenxa yokuba indlela yothumelo kunye nesalathiso se-pulse yokukhupha inxenye ngaphakathi kwemveliso yovavanyo inzima kakhulu, kufuneka sisebenzise kuphela indlela yokuthelekisa ukufumanisa inkangeleko ebonakalayo yemveliso yovavanyo.Kwintlawulo yokukhupha, oko kukuthi, ukufaka isixa esithile sombane kuzo zombini iziphelo zesampulu yovavanyo ngaphambi kovavanyo, lungisa ukukhulisa ukuseka isikali, uze uthelekise inxalenye ye-pulse yokukhupha ngaphakathi kwesampuli yovavanyo efunyenwe phantsi kweyona nto. i-voltage kunye nesikali, ukuze ufumane intlawulo ebonakalayo yokukhupha into yokuvavanya.
Idijithi yokukhutshwa kwenxalenye yedijithali iqinisekisa ukuthembeka kwedatha echongiweyo ngokulungiswa kwesignali yedijithali, ukuhluza okuguquguqukayo kunye nezinye iindlela zokuphazamiseka komqondiso wokuphazamiseka.
