TAYADA khaanadda ayaa noqon doonta tan ugu xiisaha badan oo inta badan ay walaac ka qabaan macmiil cusub oo culus!
Kuwa soo socdaa waa sharraxaad weyn oo loogu talagalay cabbirrada farsamo ee muhiimka ah:
Resistance madhxiya ama IR sida magaca ka muuqata waa iska caabinta
dahaarka IR runti waxay ka ilaalisaa qalabka korontada wareegga gaaban. Qiyamka IR
guud ahaan aad ayey ugu sarreeyaan inta u dhaxeysa Mega-ohm ama Mohm.
Wehliyaha Heerkulka waxay kuxirantahay haday dielectric tahay Class 1 ama Class 2. dhoobada
kaabayaasha (gaar ahaan fasalka 2) inta badan wuxuu leeyahay cunsur sare, isugeyn sare oo baahsan.
Cunsunka faafida (tan δ):ama DF waxaa lagu qeexaa inay tahay saamiga ESR iyo falcelinta capacitive. Waa
Cunsurka baahinta ayaa sidoo kale loo yaqaannaa taabashada xagasha luminta waxaana badanaa lagu muujiyaa boqolkiiba.
Heerarka la aqoonsan yahay waxay muujinayaan cunsuriyada ku faafisa mowjadaha gaarka ah ee caadiga ah 120Hz ee Aluminium
electrolytic iyo Tantalum capacitors halka filimada capacitors ay yihiin 1 kHz iyo 1 MHz oo loogu talagalay capacitors dhoobada.
Dheecaan Qayb ah (PD): waa dheecaan koronto ama dhimbiil oo xira qayb yar oo ka mid ah dahaadhka
inta u dhaxaysa laba qabashada korantada.PD wuxuu ku dhici karaa meel kasta oo ka mid ah nidaamka korantada, meesha garoonka korantada
xoogga ayaa ka sarreeya xoog jabidda qaybtaas maaddada dahaarka ah
dahaar adag, dusha sare ee maaddada dahaarka waxyaabaha wasakhaysan ama cilad la’aan awgeed, gudaha gaasaska
dahaaridda dareeraha ama ku wareegsan gaaska ku shaqeeya gaaska (dhaqdhaqaaqa corona).
