In kasta oo labadaba Imtixaanka Voltage-ka ee adkaysta iyo tijaabada hadda jirta loo isticmaali karo si loo tijaabiyo xoogga dahaarka ee bartilmaameedka la tijaabiyay, waxaa jira faraqyo muhiim ah oo ku jira habka tijaabada iyo natiijooyinka.Tijaabada Voltage-ka adkeysigu waxa lagu sameeyaa Voltage Sare Kadib Nidaamka Dahaarka ee dhammaan qaybaha hadda socda ee bartilmaameedka la tijaabiyay waa muddo gaaban.Tijaabada Leakge Iminka (Taabo Hadda) Waxaa Lagu Sameeyaa Xaaladaha Korontada iyadoo la adeegsanayo Qalabka Tijaabada
In kasta oo labadan imtixaan ay kala duwan yihiin, haddana aad bay faa'iido ugu leeyihiin hubinta badqabka alaabta.Tijaabada Voltage-ka ee adkeysiga waa 100% Tijaabada Joogtada ah (Tijaabada Joogtada ah), iyo Tijaabada Joogtada ah ee Joogtada ah Guud ahaan waxaa loo tixgaliyaa Imtixaan Nooc ah.
Qaadashada baahsan ee Tilmaamaha Voltage-hoose ee Maanta (LVD), U adkeysiga Tijaabada Korantada iyo Diidashada Tijaabooyinka Hadda waxay noqonayaan Tijaabooyin Khadka Wax-soo-saarka La Jaangooyay, iyo Tijaabooyin badan, sida Tijaabooyin Iska-caabbinta Dahsoon iyo Tijaabooyin Iska-caabbinta Dhulka, ayaa lagu dari doonaa.
Alaabooyinka Korantada Tayada Sare leh waa in ay ka gudbaan Tijaabooyin Heerarka Nabdoonaanta dhinacyo badan, oo ay ku jiraan U adkaysiga Tijaabada Korantada, Tijaabada U adkaysiga Dahaarka, Tijaabada Ciribtirka Dhulka, Tijaabada Hadda (Taabasho Hadda) IWM. Shaygan Heerka Badbaadada, Qaybta Dhibta leh waa Bixinta Tijaabada Hadda (Taabo Imtixaanka Hadda).Alaabtani waxay cabbiri kartaa qulqulka aan caadiga ahayn ee hadda socda iyada oo loo marayo baaritaanka hadda socda.Tijaabada Jirta ee Leakge waa Qalabka Imtixaanka Caadiga ah ee Tijaabada Hadda.
Tijaabada Bixinta Hawlgalka ee Hadda (Taabo Hadda).
Sannadihii dhawaa, Shuruuc badan oo Badbaadada Alaabtu waxay u baahan yihiin alaabada in lagu tijaabiyo daadinta hadda, hadday tahay Tijaabada Nakhshadeynta Alaabta ama Tijaabada khadka wax soo saarka, gaar ahaan Wajiga Nakhshadda.Tijaabooyinkan ka dib, Injineerada Nakhshadeynta Alaabtu waxay heli karaan macluumaad badan oo muhiim ah oo ku saabsan hufnaanta badeecada, si ay badeecada uga dhigaan mid la jaan qaadaya shuruucda badbaadada.Marka Bartilmaameedka La Tijaabiyay Lagu Tijaabo Voltage Dheeraadka ah Ama 1.1 Wakhtiyada Soosaarka Joogtada ah ee Korontada Dheeraadka ah, Taasi waa, Marka Alaabta Lagu tijaabiyo Isticmaalka Dhabta ah iyo Xaalado Khaldan, Gudaha Tijaabada Diidmada Dhulka ee Hadda, Siliga Dhulka ee Bartilmaameedka La Tijaabiyey Lagu cabbiray si loo xaqiijiyo socodka ku soo celinta hadda khadka dhexdhexaadka ah ee nidaamka.Imtixaanka hadda socda ee golaha wasiirada, waxa hadda ka socda meelo kala duwan oo golaha wasiirada ah ilaa barta dhexdhexaadka ah ee nidaamka waa la cabbiraa.
U adkeysiga Voltage (dahaarka) Tijaabada waa in lagu daydo Nidaamka Dahaarka ee Bartilmaameedka la tijaabiyay waa in uu awood u leeyahay inuu u adkeysto korantada sare muddo cayiman oo xaalado ah oo ka fog isticmaalka caadiga ah.Tijaabada Voltage-ka ee Alaabtu waxay ka dhigan tahay inay si badbaado leh ugu shaqayn karto isticmaalka caadiga ah oo ay u adkaysan karto ku-meel-gaadhka beddelka caadiga ah.Kani waa Imtixaan Guud oo Faa'iido leh, iyo Soo-saareyaasha Alaabtu sidoo kale way u isticmaali karaan si ay u xaqiijiyaan calaamada tayada aasaasiga ah ee isticmaalaha.
Isku darka Tijaabada Fudud, Xidhiidhinta Udhaxaysa Tijaabada Voltage Adkeysiga iyo Bartilmaameedka La Tijaabiyey Waxa Uu Gudbi Karaa Sanduuqa Socket-ka Ama Ledhka TijaabadaHaddii qulqulka Gudbinta hadda uu aad u weyn yahay, Tijaabada korantada ee adkaysiga ayaa muujin doona cilladaha, taasoo tusinaysa in bartilmaameedkii la tijaabiyay aanu gudbin imtixaanka.Haddi aanay jirin wax dareere ah oo xad dhaaf ah oo imminka la tijaabiyay, tijaabiyaha adkaysiga korantada ayaa tusi doona in uu hada gudbay, taas oo tusinaysa in bartilmaameedkii la tijaabiyay uu hada ka gudbay imtixaankii.Qiimaha Bixinta Xad-dhaafka ah ee hadda waxa lagu go'aamiyaa qiimaha dejiyay ee heerka ugu sarreeya ee la oggol yahay, kaas oo lagu hagaajin karo tijaabiyaha korantada ee adkaysiga si loo xaqiijiyo in imtixaanku gudbay iyo in kale.Tijaabada Korantada Adkeysiga Dhab ahaantii waxa ay diiradda saartaa heerka dahaadhka u dhexeeya kontaroolayaasha hadda socda iyo kontaroolayaasha aan hadda qaadin, sida biraha aan hadda-qaadan ee bannaanka u soo baxay.Tani waa hab Wanaagsan oo lagu Helo Dhibaatooyinka Naqshadeynta Alaabada, sida Meelaynta Kontaroolayaasha aad u dhow.
Shuruudaha Shaqo Ee U Adkeysiga Imtixaanka Korantada ee Tijaabada hadda jirta
Tijaabada hadda jirta ee uu maamulo barnaamijka, Sicirrada Badbaadada iyo Hay'adaha Sharcigu ma laha Qiimaha la qiyaasay ee Imtixaanka Cadaadiska Joogtada ah, balse waxaa go'aamiya soo saaraha Alaabta la tijaabiyay.Haddi inta ugu badan ee adkeysi u leedahay ka bixista korantada qiimaha hadda aan la cayimin, *Qaabka Tijaabada Wanaagsani waa in la Dejiyo adkaysiga Leakage Korantada Qiimaha hada ee Gaadhay Heerka Safarka, kaas oo waxyar ka sareeya Qiimaha Tijaabadu Dami Imtixaanka Hoostiisa.
U adkeysan sii daynta Voltage-ka Hadda * Tilmaamaha Badbaadada Guud iyo Faahfaahinta waxay tixraaci karaan Dhawr Sifooyin UL ah, Guud ahaan "120k Ohm" Tixraac ahaan.Tilmaamahani waxa uu dejiyaa iska caabin go'an, Kaas oo runtii u horseedi doona tilmaamid cilad ah ee u adkeysiga tijaabada korantada.Marxaladda Hore, 1000 Volts oo lagu daray laba jeer Korantada Dheeraadka ah ee Qalabka ee dhinaca Daboolka.Kani waa Dejinta Guud ee U adkaysiga Tijaabada Korantada.Tan iyo markii Voltage-ka dheeriga ah ee bartilmaameedyada Imtixaanada intooda badan laga isticmaalo gudaha Mareykanka waa 120
Tijaabada Joogtada ah ee Leakage, Hadda la Cabiray waxa loo isticmaali karaa in lagu xisaabiyo Qiyaasta Qiimaha Safarka Hadda ee Dejinta U adkaysiga Imtixaanka Korantada.Tani waa Kaliya Qiimo Qiyaasan, iyadoo ay ugu wacan tahay leexashada Qaybaha Qalabku waxay sababi karaan kala duwanaansho yar oo ku jirta daadinta akhrinta hadda ee bartilmaameedyada imtixaanada kala duwan.Markaad Xisaabinayso Goobaha Hadda Jooga ee Bixinta La Xidhiidha, Aad bay muhiim u tahay in la fahmo faraqa aasaasiga ah ee u dhexeeya Tijaabada Korantada ee Adkeysiga iyo Tijaabada hadda taagan.In kasta oo inta badan Tijaabiyayaasha hadda Leakage ay bixiyaan Tijaabooyin beddelasho Layn Output (L/N), kaliya waxay cabbiraan daadinta hadda qayb hadda socota oo ku socota kiiska aaladda lagu tijaabinayo wada jir.Tijaabada Voltage-ka Is-hortaagista waxay cabbirtaa daadinta hadda ee labada shay ee hadda wada, si ay u muujiso daadinta sare ee akhriska hadda.Xeerka Faa'iidada leh ee Suulka ayaa ah in la dejiyo U adkaysiga Safarka Tijaabada Korantada ee hadda ilaa 20% ilaa 25% ee natiijada xisaabinta ee foormulada soo socota:
(U adkaysta Tijaabada Korantada ee Voltage/Leakage) *Tijaabada Hadda Jirta = Qiyaasta Qiimaha U Adkaysiga Imtixaanka Korantada ee Hadda.
