Ọrụ Sistemu na Nhazi

Eletrik na-esi na 33 kV grid na-abanye, na-agbada ruo 11 kV site na nke a 3.5 MVA power transformer unit, wee na-azụ netwọk nkesa 11 kV. N'okpuru ala, ndị ntụgharị 750 kVA na-eweghara, n'ikpeazụ na-agbada voltaji na 0.415 kV maka ndị ọrụ njedebe. Ọkwa voltaji abụọ, tiers transformer abụọ, otu sistemu mgbanwe mgbanwe ụlọ ọrụ na-ahazi. The isi unit na-amịkọrọ mgbanwe na stabilizes netwọk; obere nkeji na-ebuga nso ibu ahụ. Ihe bara uru, enwere ike itolite, buru amụma.

Otu vector Dyn11 na-enye mmepụta waya siri ike nke atọ-fase anọ-, na-ejikwa harmonics, ma dabara nke ọma- dabara maka ibu ụlọ ọrụ na azụmahịa agwakọtara. Ikuku ọla kọpa na-eme ka nrụpụta, ịrụ ọrụ ọkụ, na ike igwe. A na-edozi okpomọkụ nke ọma, nguzogide dị ala, ndụ ọrụ ogologo oge.
