Na 2025, onye ahịa America nyere iwu maka a2660 kVA atọ nkeji mpe mpe akwa n'ịnyịnya transformer, emebere maka ntinye n'ime netwọk nkesa nkesa voltaji na United States, ebe ntụkwasị obi, nchekwa na ogologo oge- ịrụ ọrụ dị mkpa maka akụrụngwa ike ọrụ ahụ. Ihe ngbanwe ahụ na-arụ ọrụ dị ka igbe ngbanwe dị n'èzí, na-ejikọta tankị nke na-agbanwe agbanwe, akụrụngwa mgbanwe, ngwaọrụ nchebe, na ihe njikọ eletrik n'ime pad kọmpat{2} agbakwunyere ogige kwesịrị ekwesị maka netwọk nkesa ọrụ yana gburugburu ụlọ ọrụ mmepụta ihe. Na mgbakwunye, dịka akụkụ nke otu usoro ahụ, onye ahịa zụtara nke pere mpe150 kVA mpe mpe akwa n'ịnyịnya transformerinye ibu inyeaka n'ime sistemu eletriki oru ngo a.

The unit na-nyere na 2660 kVA, na a isi voltaji nke 22.8 kV na nke abụọ voltaji nke 0.8 kV, na-eji YNd1 vector otu, nke na-akwado kwụsiri ike atọ-phase voltaji mgbanwe; A na-edobe nchụpụ oge kwesịrị ekwesị na njiri ala, dịka achọrọ maka sistemu nkesa nkesa voltaji. Nhazi a na-ewedata ike ọrụ- ike voltaji nke ọma, ebe ọ na-ebuga voltaji na-agbanwe agbanwe na ibu eletrịkị na-agbadata{7}}nwere ntụkwasị obi, kwụsie ike ma dị njikere maka njikọta grid.

Ezubere ma rụpụta ya dị ka IEEE Std C57.12.34-2022 si dị, onye ngbanwe ahụ na-agbaso ụkpụrụ North America maka akụrụngwa na-ebunye ihe ngbanwe, na-eme ka ọrụ nchekwa dị na sistemụ nkesa n'okpuru ala na nrụnye n'èzí ebe a ga-eji nlezianya chịkwaa ikpughe gburugburu ebe obibi na nchekwa ọrụ.

Iji hụ na ọrụ nchekwa na ntụkwasị obi na-arụ ọrụ, onye na-ekesa ihe nkesa voltaji nwere ọtụtụ ihe nleba anya na ihe nchebe agbakwunyere n'ime igbe mkpuchi n'èzí. Atụmatụ gụnyere:

• Ala electrostatic ọta
• Ọkwa mmanụ, okpomọkụ mmanụ, na ihe nrụgide tankị
• Valve enyemaka nrụgide maka nchebe oke nrụgide
• Ndị njide ịwa ahụ
• Ụgbọ ala ọla kọpa maka njikọ na fuses mpụga
• Ibunye mgbanaka nkwụsịtụ

Ngwaọrụ	Ọrụ
