1.1 Ihe ndabere oru ngo
8 MVA auto transformer ka ebugara South Africa na 2022.
The gosiri ike nke mmanụ immersed transformer bụ 8000 KVA na ONAF jụrụ, isi voltaji bụ 33 kV na ± 10 * 1.5% tapping nso (OLTC), nke abụọ voltaji bụ 33 kV, ha guzobere vector otu YNa0. Igwe ikuku -voltaji (HV) dị elu bụ kpakpando{7} jikọtara ya na nnọpụiche (Y). ebe a enweghị ntughari oge n'etiti ikuku HV na LV (nke "0 na-egosi"). Na-enye ohere maka mgbanwe voltaji n'akụkụ oke voltaji{11} na-akwụsịghị ibu ahụ. Na-akwụ ụgwọ maka mgbanwe voltaji na grid ma ọ bụ akụkụ ibu. Ike igwe dị elu na ọkụ eletrik na-eme ka ọ dị ogologo{14}} ịrụ ọrụ na obere oge. Na ọnọdụ jụrụ oyi (ONAN), transformer nwere ike ịrụ ọrụ n'obere ikike ya zuru oke. Na ọnọdụ ONAF, mmanye ikuku jụrụ oyi na-enyere onye ntụgharị aka iru ikike ibu zuru oke (80MVA).
