1.1 Nkọwa oru ngo

Na 2024, ụlọ ọrụ anyị nyefere 37otu - pad phase {{1} agbakwunyere ngbanwenye onye ahịa na Jamaica. Nke a gụnyere nkeji 2 nke ụdị 25 kVA, ọkachasị iji nye ngwaahịa nkesa ike maka ebe obibi. Scotech ahaziri ngwọta mgbanwe kacha mma iji gboo mkpa ndị ahịa. Emebere nkeji niile na ụkpụrụ IEEE, na-ahụ na a pụrụ ịdabere na ya na ogologo oge-.

Voltaji nke izizi (elu) bụ 24GrdY/13.8 × 12GrdY/6.9 kV, nke bụ imewe- voltaji. Ndị ahịa nwere ike ịgbanwe n'etiti 13.8 kV na 6.9 kV site na iji ọnụọgụ ọnụọgụ - voltaji ahọrọ, dabere na ahịrị nkesa. O nweghị -load tap changer (NLTC) ±2×2.5% maka mmezi voltaji. Igwe ọkụ nke abụọ bụ 0.24 / 0.12 kV, dabara maka ụlọ na obere azụmaahịa. The loop{17}}nri, nwụrụ anwụ{18}} imewe n'ihu na-eme ka nrụnye dị mma ma dị mfe.

Nke 25 kvmpe mpe akwa arịọnụ transformerna-eji windings ọla kọpa, ONAN jụrụ oyi, yana mkpuchi mmanụ ịnweta. Ọ na-arụ ọrụ nke ọma ma na-adịte aka na ọnọdụ okpomọkụ. Na-arụ ọrụ na ugboro nke 50Hz, ndị a na-agbanwe agbanwe na-enweta nnukwu mfu nke 0.078 kW na- na-efu 0.165 kW.
A na-echekwa nchekwa na nchekwa site na njirimara ọkọlọtọ dị ka fuse baynet, fuse na-egbochi ugbu a (CLF), na ngwaọrụ enyemaka nrụgide, yana njide ịwa ahụ nhọrọ yana ihe nchọpụta mmejọ ime (IFD) maka nkwalite ntụkwasị obi.
Na-ejikọta ihe ndị dị elu-, kọmpat imewe na atụmatụ nchebe dị elu, ihe ngbanwe a dabara adaba maka netwọk nkesa ọgbara ọhụrụ. Ọ na-ebuga ndị obodo ike kwụsiri ike, rụọ ọrụ nke ọma na nchekwa nchekwa.
