Farqiga u dhexeeya Hababka Imtixaanka ee udhaxeeya Tijaabada Iska caabinta Dahaarka iyo Tijaabada Iska caabinta Dhulka
(1) Habka Tijaabada Tijaabada Iska caabbinta Dahaarka
Tijaabada iska caabbinta dahaarka waa inuu tijaabiyo heerka dahaadhka ee u dhexeeya wejiyada, lakabyada iyo meelaha dhexdhexaadka ah ee fiilooyinka iyo fiilooyinka.Qiimaha Tijaabada oo Sareeya, ayaa ka Wanaagsan Waxqabadka Dahaarka.Iska caabinta dahaadhka waxa lagu qiyaasi karaa UMG2672 Megohmmeter Elektroonik ah.
(2) Habka Tijaabada Tijaabada Iska caabinta Dhulka
Tijaabada iska caabinta Grounding waa qalab koronto oo ogaanaya in iska caabinta dhulku u qalmo iyo in kale.Habka Tijaabada ee Tijaabada Iska caabinta Dhulka ayaa ah in Qalabka Korontadu uu ku xidhan yahay isla awooda Dhulku, waana u dhawaanshaha Siliga falcelinta ama hadhaaga hillaaca ee dhulka.Qiimaha Uu Ku Cabiro Tijaabada Iska Caabbinta Dhulka Waa Cabbiraad Wax ku ool ah oo lagu Xaqiijinayo Badbaadada Shaqsiyeed.Waxaad dooran kartaa DER2571 Dijital ah Tijaabada Iska caabinta Dhulka oo ay soo saartay Awoodda WeiA.
Afar, Farqiga Mabaadi'da ee udhaxeeya Tijaabiyaha Iska caabbinta Dahaarka iyo Tijaabada Iska caabinta Dhulka
(1) Mabda'a Tijaabada Iska-caabbinta Dahaarka
Marka Tijaabada iska caabbinta dahaarka loo isticmaalo in lagu cabbiro iska caabbinta dahaarka, DC Voltage U ayaa lagu dabaqaa dahaarka.Waqtigan xaadirka ah, wakhtigan xaadirka ah ayaa isbedelaya feejignaanta, oo ugu dambeyntii u janjeerta qiimo xasilloon.
Guud ahaan, wakhtigan xaadirka ah Tijaabada iska caabbinta dahaarka waa wadarta awooda hadda, nuugista hadda iyo hadda shaqaynta.Capacitive Current Ic, Xawaarihiisa Attenuation aad ayuu u Dhakhso badan yahay;Nuugista hadda Iaδc, Aad ayuu uga gaabis badan yahay hadda;Qabashada Inp hadda, waxay u egtahay inay ku xasili karto waqti gaaban gudaheed.
Inta lagu jiro Imtixaanka Isticmaalka Tijaabada Iska caabinta Dahaarka, Haddii dahaarku aanu qoyanayn oo dusha sare uu nadiif yahay, Qaybaha Ku-meel-gaadhka ah ee hadda Ic iyo Iaδc waxay si dhakhso ah u daalan doonaan Eber, iyagoo ka tagaya kaliya wax-qabad yar oo hadda socda si ay u gudubto, sababtoo ah iska caabbinta dahaarka ayaa ka duwan. Marka loo eego wakhtiga wareega, iska caabinta dahaarka ayaa si degdeg ah u kici doona oo ku xasili doona qiimo weyn.Taa beddelkeeda, haddii dahaarku qoyan yahay, wax-qabadka hadda si weyn ayuu u kordhayaa, xitaa wuu ka dhaqso badan yahay qiimaha ugu horreeya ee nuugista Iaδc ee hadda jira, qaybta ku-meel-gaadhka ah ee hadda jirta si weyn ayaa loo dhimay, iyo qiimaha iska caabbinta dahaarka aad ayuu u hooseeyaa, oo si weyn ayay isu beddeshaa wakhtiga.Micro.
Sidaa darteed, Tijaabada Tijaabada Iska-caabbinta Dahaarka, waxa ka kooban qoyaanka dahaarka guud ahaan waxaa lagu qiimeeyaa saamiga nuugista.Marka saamiga nuugista uu ka weyn yahay 1.3, waxay muujinaysaa in dahaarka uu aad u fiican yahay.Haddii saamiga nuugista uu ku dhow yahay 1, waxay muujinaysaa in dahaarka uu qoyan yahay.
(2) Mabda'a Tijaabada Iska caabinta Dhulka
Tijaabada iska caabbinta dhulka waxa sidoo kale loogu yeedhaa Qalabka Cabbiraadda iska caabinta dhulka, ruxruxinta dhulka.Mabda'a Tijaabada Imtixaanka Iska caabinta Dhulka waa in lagu Helo Qiimaha Iska caabinta Dhulka "Rx" Iyadoo loo marayo AC Constant Iminka "I" inta u dhaxaysa Ground Electrode "E" iyo Korontada Bixinta Electrode "H(C)" ee Shayga Imtixaanka ku jira, Waxaana Dhulka La Helay Farqiga Mawqifka "V" ee u dhexeeya Electrode "E" iyo Cabbirka Electrode"S(P)".
