Nke a750kVA atọ agba mpe mpe akwa n'ịnyịnya transformerebugara America na 2024. Emere ya n'okpuru IEEE Std C57.12.34-2022 wee zute ọkọlọtọ nrụpụta ike ike DOE 2016. Nrụ ọrụ bụ 99.4%. Ọ nwere akara akaghị aka na imewe n'ihu maka nchekwa ma dị mfe na mpaghara mmepụta ihe na azụmahịa. Ike a kwadoro bụ 750kVA, yana voltaji bụ isi nke 13.2 kV na voltaji nke abụọ nke 0.48 kV. Ihe ntụgharị bụ UL edepụtara, na-ezute ụkpụrụ nchekwa US.

Ihe mgbochi bụ 5.75%. Ọnwụ enweghị - bụ 1.05kW. Mbelata ibu bụ 5.4kW. Mfu ndị a dị ala na-azọpụta ike ma melite arụmọrụ. Onye na-agbanwe mgbata abụghị - ụdị ibu (NLTC). Ọ nwere oke ± 2 × 2.5% iji dozie voltaji.
