Tijaabada iska caabbinta dahaarka ayaa ku haboon cabbiraadda qiimaha iska caabinta alaabada kala duwan ee dahaarka iyo iska caabbinta dahaarka ee Transformers, Motors, Fiilooyinka iyo Qalabka Korontada, si loo hubiyo in qalabkan, Qalabka Korontada iyo Xadhkaha ay ku shaqeeyaan xaalado caadi ah si looga fogaado shoogga korontada Waxyeello
Dhibaatooyinka caadiga ah ee tijaabiyaha iska caabbinta dahaarka waa sida soo socota:
1. Marka la Cabbirayo Caabbinta Culayska Awoodda leh, waa maxay xidhiidhka ka dhexeeya soo-saarka wareegga-gaaban ee imminka Tijaabada iska caabbinta dahaarka iyo xogta la cabbiray, waayo?
Cabbirka soo-saarka wareegga-gaaban ee hadda ee tijaabiyaha iska caabbinta dahaarka ayaa ka tarjumi kara cabbirka iska caabbinta gudaha ee isha-Voltage-sare ee gudaha Megger.
Tijaabooyin badan oo dahaarka ah ayaa bartilmaameedsada culaysyo awood leh, sida fiilooyinka dhaadheer, matoorada leh dabaylo badan, iyo beddelayaal.Sidaa darteed, Marka Bartilmaameedka la Cabiray uu leeyahay Awood, Bilowga Habka Imtixaanka, Isha-Voltage-sare ee Tijaabada iska caabbinta daahyada waa in uu ku dallaco Capacitor-ka iyada oo loo marayo iska caabin gudaha ah, oo si tartiib tartiib ah ugu dallacaa Voltage-ka soo-saarka tamarta sare ee dheeraadka ah Tijaabada iska caabinta dahaarka..Haddii Qiimaha Kartida ee Bartilmaameedka La Cabiray uu weyn yahay, ama iska caabinta Gudeed ee Isha-Voltage-ka Sare ay tahay mid weyn, Habka Dallacadu waxay qaadan doontaa waqti dheer.
Dhererkeeda waxaa lagu go'aamin karaa badeecada R Gudaha iyo C (Cutubka: Labaad), Yacni, T=R Gudaha*C Load.
Sidaa darteed, Inta lagu jiro Imtixaanka, waxaa lagama maarmaan ah in lagu dallaco culeyska awoodda leh ee Voltage-ka Tijaabada, iyo Xawaaraha Dallacaadda DV/Dt wuxuu la mid yahay saamiga ku dallacaadda hadda I ee Awoodda Xamuulka C. Taasi waa, DV/Dt= I/C
Sidaa darteed, Inta yar ee iska caabinta gudaha iyo ka weyn ee dallacaadda hadda, sida ugu dhakhsaha badan natiijooyinka imtixaanku waxay noqon doonaan kuwo deggan.
2. Waa maxay shaqada dhinaca "G" ee Muuqa?Deegaanka Tijaabada Sare-Voltage iyo Iska caabinta Sare, maxaa loogu baahan yahay in lagu xidho Terminalka "G" Dibadda?
Dhamaadka "G" ee Dusha sare waa Gashaan gaashaamo ah.Shaqada Terminalka gaashaammadu waa in meesha laga saaro saamaynta qoyaanka iyo wasakhda deegaanka tijaabada ee natiijooyinka cabbirka.Terminalka "G" ee Dibeda waxa uu dhaafaa daadinta hadda ee alaabta la tijaabiyay, si aanay dareeruhu hadda u dhaafin wareegga tijaabada dibadeed, oo uu baabi'iyo khaladka uu keeno qulqulka hadda.Terminalka G waxa la isticmaalaa marka la tijaabinayo iska caabin sare.
Guud ahaan hadalka, G Terminal-ka waxaa loo tixgalin karaa in ka badan 10G.Si kastaba ha ahaatee, Xaddigan iska caabinta lama hubo.Marka ay nadiif tahay oo ay engegan tahay oo mugga shayga imtixaanku uu yar yahay, way xasiloon kartaa iyada oo aan lagu cabbirin 500G dhamaadka G.Deegaanka qoyaanka iyo wasakhda ah, Qiimaha iska caabinta Hoose ayaa sidoo kale u baahan G Dhamaadka.Gaar ahaan, Haddii aad ogaato in natiijadu ay adag tahay in la dejiyo marka la cabbirayo iska caabin sare, waxaad ka fiirsan kartaa isticmaalka G Terminalka.Sidoo kale ogow in Terminalka gaashaammadu aanu ku xidhnayn lakabka gaashaanka, balse uu ku xidhan yahay dahaarka u dhexeeya L iyo E ama silig-ka xidhan ee badan, oo aan ku xidhnayn fiilooyinka kale ee la tijaabinayo.
3. Maxaa Looga Baahn Yahay Kaliya In La Cabiro Qiimaha Iska-caabbinta Saafiga ah Marka la Cabbirayo Insulation, Laakiin Sidoo kale in la Cabirro Saamiga Nuugista iyo Tusaha Polarization.Waa maxay Ujeedadu?
PI waa Tusaha Polarization-ka, kaas oo tixraacaya isbarbardhigga u dhexeeya iska caabbinta dahaarka ee 10 daqiiqo iyo caabbinta dahaarka ee 1 daqiiqo inta lagu jiro tijaabada dahaarka;
DAR waa saamiga nuugista dielectric, kaas oo tixraacaya isbarbardhigga u dhexeeya iska caabbinta dahaarka ee 1 daqiiqo iyo caabbinta xakamaynta ee 15s inta lagu jiro Imtixaanka Insulation;
Tijaabada Dahaarka, Qiimaha Iska-caabbinta Dahaarka ee Daqiiqado qaarkood si buuxda uma tarjumi karo Shaqada Dahaarka ee Tusaalaha Imtixaanka.Taasna waxa u sabab ah labadan sababood ee soo socda.Dhinaca kale, iska caabbinta dahaarka ee isla shaqada walxaha dahaarka ayaa yar marka uu mugga weyn yahay., Iska caabbinta dahaarka ayaa soo baxa marka uu mugga yar yahay.Dhanka kale, Walxaha dahaadhiduhu waxay leeyihiin habka saamiga nuugista iyo habka kala soocida ee kharashka ka dib marka korontadu sarreeyso la dabaqo.Sidaa darteed, Nidaamka Korontadu wuxuu u baahan yahay cabbirka saamiga nuugista - saamiga R60s iyo R15s, iyo Tusaha Polarization - Saamiga R10min iyo R1min ee Tijaabada Dahaarka ee Transformers, Fiilooyinka, Matoorada iyo Marxalado kale oo badan oo badan, oo isticmaal tan Xogta si loo go'aamiyo dahaarka Wanaagsan ama Xun.
4. Muxuu Tijaabaha Iska caabbinta Dahaarka Elektarooniga ah u soo saari karaa koronto-sare oo DC ah marka ay ku shaqeeyaan baytariyo dhowr ah?Tani Waxay Ku Salaysan tahay Mabda'a Beddelka DC.Korontada Bixinta Korontada Hoose Waxaa Lagu Kordhiyaa Wax-soosaarka Sare ee DC-ga iyada oo loo marayo Habaynta Wareegga Kobcinta.Korontada Sare ee la dhaliyo ayaa ka sarraysa balse awooda wax soo saarku waa mid yar (Tamar yar iyo hadda yar).
Fiiro gaar ah: Xitaa haddii ay awooddu aad u yar tahay, laguma talinayo in shakhsi ahaan loo taabto baaritaanka tijaabada, wali waxaa jiri doona dareen tingling.
