1.1 Nkọwa oru ngo

Ebutere ya na USA na 2024, 2000 kVA atọ -phase pad- nkesa ihe nkesa ka arụnyere iji kwado IEEE Std C57.12.34-2022 wee kwekọọ n'ụkpụrụ nrụpụta ike ike DOE 2016. Ihe ngbanwe ahụ nwere isi 4.16 kV yana 480GrdY/277 V nke nwere otu vector Dyn1. Ọ na-eji windings ọla kọpa maka ịrụ ọrụ a pụrụ ịdabere na ya na ịdịte aka, KNAN jụrụ maka ịgbasa ọkụ dị mma, yana mmiri ester FR3 eke maka nchekwa ọkụ ka mma na nkwado gburugburu ebe obibi.

Nhazi ahụ nwere sistemu ndepụta loop ma nwụọ- ohere ihu, na-akwado ma ọrụ nchekwa yana mgbanwe nrụnye. Ọ gụnyekwara ihe ngbanwe enweghị- nwere oke nhazi voltaji ±2 × 2.5%. Site na ihe mgbochi nke 5.75%, enweghị- ibu efu nke 1.350 kW, yana mfu nke 16.000 kW, ihe ngbanwe a na-ebuga ngbanwe ike dị mma ma kwụsie ike maka sistemu nkesa voltaji{10}.

Ezubere iji gboo ihe achọrọ nke ụlọ ọrụ na ntọala ụlọ ọrụ nke oge a, pad anyị{0} mounted nkesa transformers na-enye kọmpat, obere{1}profaịlụ na-emebighị na nchekwa ma ọ bụ ogologo oge-.
