Zvinotevera zvikuru tsanangudzo inokosha michina parameters:
Insulation Nemishonga kana IR sezvinonzi zita rinoratidza kushorwa kwe
kuputira. IR inodzivirira chaizvo zvemagetsi kubva pfupi pfupi IR tsika
anowanzo kuve akakwirira kwazvo munzvimbo ye Mega-ohm kana Mohm.
Temperature Coefficient zvinoenderana nekuti dielectric iri Kirasi 1 kana Kirasi 2. A ceramic
capacitor (kunyanya iyo kirasi 2) kazhinji ine yakanyanya dissipation factor, yakakwira frequency coefficient yekuparara.
Kuparara kwechinhu (tan δ):kana DF inotsanangurwa seyero yeESR uye capacitive reactance. Ndiyo
dissipation factor inozivikanwawo setangent yekurasikirwa kona uye inowanzo kuratidzwa muzana.
Mitezo inozivikanwa inozivikanwa inoratidza iyo dissipation chinhu pane chaiwo maficha anowanzoita 120Hz yeAluminium
electrolytic uye Tantalum capacitors apo yemafirimu capacitors ndeye 1 kHz uye 1 MHz yekeramic capacitors.
Kuparadzaniswa Kwemazana (PD): iyo kubuda kwemagetsi kana spark inokonzera chikamu chiduku chekudzivirira
pakati vaviri achiitisa electrodes.PD kunogona kuitika chero nguva iri kuputira mugadziriro, uko yemagetsi munda
simba kwazvo yokuparara simba kuti chikamu insulating material.PD munogona voids mukati
hwakasimba kuputira, mhiri pemvura insulating zvinhu nokuda utachiona kana hadzina kufambiswa zvakanaka, mukati gasi matema
mune mvura kuputira kana zvichifanira electrode muna gasi (Corona basa).
