Maqaalkii ugu dambeeyay, waxaan soo bandhignay qaraar ku saabsan DC AC. "Dagaalku" wuxuu ku dhammaaday guushii AC. Sidaa darteed, AC waxay heshay guga horumarinta suuqa waxayna bilowday inay qabsato suuqa ay hore u haysatay DC. "Dagaalkan" ka dib, DC iyo AC waxay ku tartameen saldhigga korontada ee Adams ee Niagara Falls.
Sannadkii 1890, Mareykanka wuxuu dhisay saldhigga korontada Niagara Falls Adams. Si loo qiimeeyo qorshayaasha kala duwan ee AC iyo DC, waxaa la aasaasay Guddiga Korontada Niagara ee heer qaran iyo heer caalami ah. Westinghouse iyo Ge ayaa ka qayb qaatay tartanka. Ugu dambeyntii, iyadoo sumcaddeeda ay soo ifbaxday ka dib guushii dagaalkii AC/DC iyo kartida koox saynisyahano heer sare ah sida Tesla, iyo sidoo kale tijaabadii guusha lahayd ee gudbinta AC ee Great Barrington sannadkii 1886 iyo hawlgalkii guusha lahaa ee alternator-ka warshadda korontada ee larffen ee Jarmalka, Westinghouse ugu dambeyntii waxay ku guuleysatay qandaraaska wax soo saarka ee 10 matoorro koronto oo AC ah oo 5000P ah. Sannadkii 1894, matoorkii ugu horreeyay ee 5000P ee saldhigga korontada ee Niagara Falls Adams ayaa ku dhashay Westinghouse. Sannadkii 1895, cutubkii ugu horreeyay ayaa la hawlgeliyay. Dayrtii 1896, hadda laba-waji ah ee beddela ee uu soo saaro matoorku waxaa loo beddelay saddex-waji iyada oo loo marayo transformer-ka Scot, ka dibna waxaa loo gudbiyay Baffalo oo 40km u jirta nidaamka gudbinta saddex-waji ah.
Matoorka korontada ee saldhigga korontada Adams ee Niagara Falls waxaa naqshadeeyay BG lamme (1884-1924), oo ah injineerka ugu sareeya Westinghouse, sida laga soo xigtay patent-ka Tesla, walaashiis B. lamme ayaa sidoo kale ka qayb qaadatay naqshadeynta. Cutubka waxaa ku shaqeeya matoor afar-geesood ah (laba-wajiye, oo aan lahayn tuubo qabyo ah), matoorkuna waa matoor laba-waji ah oo toosan, 5000hp, 2000V, 25Hz, 250r / mln. Matoorku wuxuu leeyahay sifooyinka soo socda;
(1) Awood weyn iyo cabbir dheer. Kahor intaas, awoodda halbeegga ah ee matoorka biyaha ma dhaafin 1000 HPA. Waxaa la dhihi karaa matoorka biyaha ee 5000bp ee saldhigga korontada biyaha ee Adar ee Niagara Falls ma ahayn oo keliya matoorka biyaha ee ugu weyn oo leh awood halbeeg ah adduunka waqtigaas, laakiin sidoo kale waa tallaabada ugu horreysa ee muhiimka ah ee horumarinta matoorka biyaha laga bilaabo yar ilaa weyn.
(2) Kondurka armature-ka waxaa markii ugu horreysay lagu dahaadhay mica.
(3) Qaababka aasaasiga ah ee dhismaha matoorada biyaha ee maanta waa la qaataa, sida qaab-dhismeedka dalladda toosan ee xiran. 8-da qaybood ee ugu horreeya waxay ka mid yihiin qaab-dhismeedka ay tiirarka birlabku ku taagan yihiin dibadda (nooca pivot), labada qaybood ee ugu dambeeyana waxaa loo beddelaa qaab-dhismeedka guud ee hadda jira kaas oo tiirarka birlabku ku wareegaan gudaha (nooca goobta).
(4) Habka kicinta gaarka ah. Kan ugu horreeya wuxuu adeegsadaa korontada DC-ga ee uu soo saaro matoorka dabaysha ee DC ee u dhow si uu u kiciyo. Laba ama saddex sano ka dib, dhammaan cutubyadu waxay u isticmaali doonaan matoorro yar yar oo korontada DC ah sida kiciyeyaasha.
(5) Soo noqnoqoshada 25Hz ayaa la qaatay. Waqtigaas, heerka Ying ee Mareykanka aad ayuu u kala duwanaa, laga bilaabo 16.67hz ilaa 1000fhz. Ka dib falanqayn iyo tanaasul, 25Hz ayaa la qaatay. Soo noqnoqoshadani waxay noqotay soo noqnoqoshada caadiga ah ee qaybo ka mid ah Mareykanka muddo dheer.
(6) Waagii hore, korontada ay soo saarto qalabka korontada dhaliya waxaa inta badan loo isticmaali jiray nalalka, halka korontada ay soo saarto saldhigga korontada ee Niagara Falls Adams ay inta badan u isticmaali jirtay korontada warshadaha.
(7) Gudbinta ganacsiga masaafada dheer ee AC-da saddex-geesoodka ah ayaa markii ugu horreysay la hirgeliyay, taas oo door tusaale ah ka ciyaartay gudbinta iyo adeegsiga ballaaran ee AC-da saddex-geesoodka ah. Ka dib 10 sano oo shaqo ah, 10 cutub oo matoorro biyood ah oo 5000bp ah oo saldhigga korontada ee Adams ayaa si buuxda loo cusbooneysiiyay oo loo beddelay. Dhammaan 10-ka cutub waxaa lagu beddelay cutubyo cusub oo ah 1000HP iyo 1200V, cutub kale oo cusub oo 5000P ah ayaa la rakibay, si wadarta awoodda la rakibay ee saldhigga korontada ay u gaarto 105000hp.
Dagaalkii AC-ga tooska ah ee matoorka korontada dhaliya waxaa ugu dambeyntii ku guuleystay AC. Tan iyo markaas, firfircoonida DC aad ayay u dhaawacday, AC-na waxay bilowday inay heesto oo ay weerarto suuqa, taas oo sidoo kale dejisay qaabka horumarinta matoorada korontada dhaliya mustaqbalka. Si kastaba ha ahaatee, waxaa xusid mudan in astaamo cajiib ah oo marxaladda hore ah ay tahay in matoorada korontada dhaliya ee DC si weyn loo isticmaalo. Waqtigaas, waxaa jiray laba nooc oo matoorada korontada dhaliya ee DC ah. Mid waa matoor koronto yar. Laba matoor ayaa isku xiran taxane waxaana wada hal matoor. Tan labaad waa matoor koronto badan, kaas oo ah matoor laba jibbaaran iyo matoor laba jibbaaran oo wadaaga hal usheeda. Faahfaahinta waxaa lagu soo bandhigi doonaa maqaalka xiga.
