1.1 Tlhaloso ea Morero
Transformer ena ea 50 kVA single{1}}mohato oa mothapo oa motlakase kee entsoeng ke Scotechle ho romeloa Canada. Transformer e lumellana ka botlalo le litekanyetso tsa IEEE C57.12.20, ho netefatsa ts'ebetso e tšepahalang bakeng sa marang-rang a kabo ea khoebo ea bolulo le e bobebe.
Odara ena e kenyelletsa likarolo tse 20 tsa -phase pole{2}}li-transformer tse kentsoeng, tseo har'a tsona li-unit tse 5 e leng tsa mofuta ona oa 50 kVA. Transformer ka 'ngoe e etselitsoe motlakase oa 7.97/13.8Y kV le motlakase oa bobeli oa 277 V, o nang le li-bushings tse peli tse phahameng-le li-voltage tse peli tse tlase{10}}. Transformer e na le-load tap changer (NLTC) e nang le sebaka sa ±2×2.5%.
Transformer ea 50 kVA mothapong oa motlakase e sebelisa motsoako oa amorphous alloy core, e fokotsang-tahlehelo ea mojaro ho 0.043 kW le tahlehelo ea mojaro ho 0.5 kW. E baballa-matla ebile e baballa tikoloho, e fokotsa litšenyehelo tsa motlakase.
Transformer e boima ba lik'hilograma tse 327, ho kenyelletsa le 81 kg ea oli e sireletsang. Oli e thusa ka ho pholisa le ho kenya letsoho. Boholo ba eona ke 645 × 715 × 1115 limilimithara. Moetso o monyane le o leka-lekaneng o kena hantle holim'a palo{8}}ea mohala oa motlakase o phahamisitsoeng. Mookameli oa "surge arrester" o lumella ho kopanya habonolo ha lisebelisoa tsa tšireletso, ho matlafatsa botšepehi le polokeho.
E entsoe ka li-windings tsa aluminium, polarity e eketsehileng, le pholiso ea tlhaho ea ONAN, transformer ena e holim'a mohala oa motlakase e sebetsa hantle, e sebetsa hantle ebile e tšepahala haholo. Kaho ea aluminium le moralo o bohlale li fana ka tharollo e feto-fetohang bakeng sa lits'ebetso tsa sejoale-joale tsa kabo ea matla, ho netefatsa ts'ebetso ea matla le ts'ebetso e tšepahalang.
