Dhab ahaantii, fahamka noocan ahi wuxuu leeyahay heer go'an oo hal dhinac ah.

Cilmi-baarista aasaasiga ah ee aragtida iyo tijaabooyinka gaarka ah waxay muujinayaan in qodobka aasaasiga ah ee shilka badbaadada ee awooddaqalabka qaybintawaa isbeddelka togan iyo midka taban ee korantada marka nidaamka qaybinta korontadu uu waxyeelo u geysto danab, gaar ahaan beddelka beddelka xad-dhaafka ah ee dhaawaca shilka badbaadada.Hadda waxaan falanqeyneynaa dhammaan habka horumarka ee isbeddelka isbeddelka togan iyo kuwa taban, dayactirka ilaalinta hillaaca ee xakamaynta tamarta.

Beddelka togan iyo midka taban ee korontadu.

Marka dhinaca korantada hoose ee qaybta ay soo gaadhay hillaac, duullaan socodka hillaaca ee iska caabbinta dabaysha yar-yar, iska caabbinta dabaysha-hooseeya iyadoo la raacayo aaladda dhulka dhexdhexaadka ah ee wadada, aaladda qulqulka korantada ee dhulka Ijd ee iska caabinta khadka dhulka RJD ayaa sababay hoos u dhaca cadaadiska.Noocan ah hoos u dhaca cadaadiska ayaa ka dhigaya farqiga suurtagalka ah ee khadka dhexdhexaadka ah ee dhinaca korantada hoose ee kor u kaca.

Waxay ku ururtaa koronto-dhaafka iska caabbinta dabaysha-yar-yar waxayna si dhab ah khatar u gelinaysaa iska caabbinta dabaysha-yar ee danab-yar.Isla mar ahaantaana, danab tani waxay u kacdaa dhinaca korantada sare iyadoo loo eegayo saamaynta magnetic ee hadda ee Kor-voltage iyo iska caabbinta dabaysha yar-yar waxayna ku ururtaa farqiga wejiga ee danab ka shaqeeya Kor-voltage caabbinta, taasoo keenta khatar badan Voltage of Kor-voltage caabbinta dabaylaha.Transformers nooca qalalan.

Tan waxa loo yaqaan overvoltage beddelka togan, kaas oo ay keento hillaaca ku dhufashada xad-dhaafka ah ee dabaysha danab yar, kaas oo loo beddelo dhinaca tamarta sare iyadoo loo eegayo saamaynta magnetic ee hadda, taasoo keentay in xad-dhaaf ah ee dabaysha danab sare.

Marka dhinaca danabka sare ee dariiqa ay la soo gudboonaato shaqo-joojin, danabku wuxuu ku dhuftey socodka korantada iyadoo loo eegayo dallacaadda danabka sare ee dallacaadda iyo ku dallacaadda waddada, qalabka dhulka hoostiisa socodka korantada ee IJD ee iska caabinta khadka dhulka ee RJD ayaa sababay hoos u dhac cadaadis ah.Cadaadiska noocan oo kale ah ee dhinaca korantada hoose ee xariiqda dhexdhexaadka ah ayaa saameyn ku leh, dhinaca korantada hoose ee albaabka laga soo galo iyo ka bixista waxay u dhigantaa marka loo eego qalabka dhulka hoostiisa ee resistor.Natiijo ahaan, inta badan korantada hawlgalka ayaa lagu daraadabaysha danab yariska caabin.Transformers nooca qalalan.

Intaa waxaa dheer, marka loo eego saamaynta magnetic ee hadda, hoos u dhaca cadaadiskani wuxuu u kacaa dhinaca korantada sare ee saamiga isbeddelka wuxuuna ku ururaa korantada DC ee dabaysha sare ee tamarta sare, taasoo keenaysa koronto-dhaafka ah ee dabaysha sare ee kor u kaca oo keenaya a dhacdada badbaadada dhexgalka.

Xaaladdan waxaa loo yaqaan 'overvoltage', halkaas oo dhinaca korantada hooseeya loo beddelo dhinaca tamarta sare ee saamaynta magnetic ee hadda, sababtoo ah dhinaca tamarta sare waxaa ku dhuftey hillaac.
