01 Izugbe

1.1 Nkọwa oru ngo

100 kVA eriri ọkụ na transformers ka ebugara Guyana na 2025. Ike nke transformer bụ 100 kVA na ONAN jụrụ oyi. The elu voltaji bụ 13.8 kV na ± 2 * 2.5% tapping nso (NLTC), ala voltaji bụ 0,12 / 0,24 kV, ha guzobere a vector otu Ii0.

A na-eji eriri ọkụ bụ 13.8kV rụọ ọrụ eletriki eletrik 100kVA na ihe ntụgharị ọkụ na voltaji nke abụọ nke 0.12/0.24kV, ahaziri maka ngwa ngwa n'elu grid- voltaji. Ewuru ya na nnukwu-arụmọrụ laminated silicon steel core na premium conductive windings, ọ nakweere mmanụ akpọchiri nke ọma-juputara imewe na ikuku jụrụ oyi (ONAN), na-eme ka nrụpụta voltaji kwụsie ike, ultra{8}} obere enweghị- ibu & ibu ibu, yana ntachi obi siri ike.
