N'isiokwu gara aga, anyị webatara mkpebi nke DC AC. "Agha" ahụ kwụsịrị site na mmeri nke AC. Ya mere, AC nwetara mmalite nke mmepe ahịa wee malite ibi n'ahịa nke DC biri na mbụ. Mgbe "agha" a gasịrị, DC na AC so na-asọmpi na ọdụ ike mmiri Adams na Niagara Falls.
Na 1890, mba Amerịka wuru ọdụ ọkụ eletrik Niagara Falls Adams. Iji nyochaa atụmatụ AC na DC dị iche iche, e guzobere Kọmitii Ike Niagara nke mba na nke mba ụwa. Westinghouse na Ge sonyere na asọmpi ahụ. N'ikpeazụ, site na aha ọma ya mgbe mmeri nke agha AC / DC gasịrị na nkà nke otu ndị ọkà mmụta sayensị dị mma dịka Tesla, yana nnwale gara nke ọma nke nnyefe AC na Great Barrington na 1886 na ọrụ alternator na-aga nke ọma na ụlọ ọrụ ọkụ eletrik larffen na Germany, Westinghouse mechara merie nkwekọrịta nrụpụta nke jenerato 10 AC 5000P. Na 1894, e mụrụ jenerato 5000P mbụ nke ọdụ ọkụ eletrik Niagara Falls Adams na Westinghouse. Na 1895, e tinyere nkeji mbụ n'ọrụ. Na mgbụsị akwụkwọ nke 1896, agbanwere ọkụ eletrik abụọ nke jenerato mepụtara ka ọ bụrụ nke atọ site na transformer Scot, wee bufee ya na Baffalo 40km site na sistemụ nnyefe atọ.
Dịka ikike Tesla si kwuo, BG lamme (1884-1924), onye injinia Westinghouse, chepụtara ihe na-emepụta mmiri nke ọdụ ọkụ eletrik Adams dị na Niagara Falls, na nwanne ya nwanyị B. lamme sokwa na nhazi ahụ. A na-eji ígwè fournellon turbine (onye na-agba ọsọ abụọ, na-enweghị ọkpọkọ draft), jenerato ahụ bụkwa jenerato nwere usoro abụọ kwụ ọtọ, 5000hp, 2000V, 25Hz, 250r / mln. Jenerato ahụ nwere njirimara ndị a;
(1) Nnukwu ikike na nha dị ogologo. Tupu nke ahụ, ikike otu unit nke jenereta mmiri agafeghị 1000 HPA. A pụrụ ikwu na jenereta mmiri 5000bp nke ọdụ ike mmiri Adar dị na Niagara Falls abụghị naanị jenereta mmiri kachasị ukwuu nwere ikike otu unit n'ụwa n'oge ahụ, kamakwa ọ bụ nzọụkwụ mbụ dị mkpa na mmepe nke jenereta mmiri site na obere ruo na nnukwu.
(2) A na-eji mica kpuchie ihe na-eduzi armature ahụ maka oge mbụ.
(3) A na-eji ụdị nhazi nke ihe ndị na-emepụta mmiri nke oge a eme ihe, dịka usoro nche anwụ kwụ ọtọ. Seti asatọ mbụ bụ nke usoro ebe ogwe magnetik na-anọ n'èzí (ụdị pivot), a na-agbanwekwa seti abụọ ikpeazụ ka ọ bụrụ usoro izugbe ugbu a nke ogwe magnetik na-agbagharị n'ime (ụdị ubi).
(4) Ụdị mkpali pụrụ iche. Nke mbụ na-eji ike DC nke ihe na-emepụta turbine DC dị nso na-emepụta maka mkpali. Mgbe afọ abụọ ma ọ bụ atọ gachara, nkeji niile ga-eji obere ihe na-emepụta mmiri DC dị ka ihe na-akpali akpali.
(5) A nabatara ugboro ole nke 25Hz. N'oge ahụ, ọnụego Ying nke United States dị nnọọ iche, site na 16.67hz ruo 1000fhz. Mgbe nyochachara ma kwekọrịtara, a nabatara 25Hz. Ugboro ole a aghọọla ugboro ole a na-ahụkarị n'akụkụ ụfọdụ nke United States ruo ogologo oge.
(6) N'oge gara aga, a na-ejikarị ọkụ eletrik nke akụrụngwa mmepụta ike emepụta maka ọkụ, ebe ọkụ eletrik nke ọdụ ọkụ Niagara Falls Adams mepụtara bụ nke a na-ejikarị eme ihe maka ọkụ ụlọ ọrụ mmepụta ihe.
(7) Emeela mbufe azụmahịa ogologo oge nke AC nke nwere usoro atọ, nke rụrụ ọrụ dị mma n'izipu na itinye AC nke nwere usoro atọ n'ọtụtụ ebe. Mgbe afọ iri nke ọrụ gasịrị, emelitere ma gbanwee nkeji iri nke na-enye turbine mmiri 5000bp nke ọdụ ọkụ eletrik Adams. Ejirila nkeji iri ọhụrụ nke 1000HP na 1200V dochie nkeji iri niile, tinyekwa nkeji ọhụrụ nke 5000P ọzọ, nke mere na ike zuru oke nke ọdụ ọkụ eletrik ruru 105000hp.
Agha nke AC kpọmkwem nke jenerato mmiri mechara merie site na AC. Kemgbe ahụ, ike nke DC emebiela nke ukwuu, AC amalitekwala ịbụ abụ ma wakpoo n'ahịa, nke setịpụkwara ụda maka mmepe nke jenerato mmiri n'ọdịnihu. Agbanyeghị, ọ dị mkpa ikwu na ihe dị ịrịba ama nke ọkwa mbụ bụ na a na-eji jenerato mmiri DC eme ihe nke ukwuu. N'oge ahụ, e nwere ụdị injin abụọ nke DC hydro. Otu bụ jenerato voltaji dị ala. Ejikọtara jenerato abụọ n'usoro ma otu turbine na-anya ya. Nke abụọ bụ jenerato voltaji dị elu, nke bụ jenerato pole abụọ na-ekerịta otu shaft. A ga-ewebata nkọwa ndị a n'isiokwu na-esote.
