1.1 Nkọwa oru ngo

Nke 500 kVA atọ -phase pad{2}} nke etinyere ngbanwe, nke ewepụtara na USA na 2024, ka arụpụtara iji zute ụkpụrụ arụmọrụ IEEE Std C57.12.34-2022 na DOE 2016.

Na-arụ ọrụ na 60 Hz, ọ na-egosipụta isi voltaji nke 24 kV na voltaji nke abụọ nke 480GrdY/277 V nwere otu Dyn1 vector. Ihe ngbanwe ahụ na-eji windings ọla kọpa na ntụ oyi KNAN, jupụtara na mmanụ ester eke FR3 maka nchekwa ọkụ ka mma yana nnabata gburugburu ebe obibi. Ọ gụnyere ikike nri loop, nwụrụ anwụ -ịnweta ihu, yana enweghị -mgbanwe mgbata nwere oke mgbanwe voltaji ±2 × 2.5%. Site na ihe mgbochi nke 5.75%, enweghị - ibu mfu nke 0.610 kW, yana na mfu nke 4.530 kW, nkeji a na-ebuga nkesa nke ọma na ntụkwasị obi{18}} ike voltaji. Ọ dị mma maka iji na ogige azụmahịa, obere ụlọ ọrụ mmepụta ihe, na mmepe obibi ebe achọrọ mgbanwe ike dị mma, na-agbanwe agbanwe na nke ọma.
