01 Kakaretso
1.1 Semelo sa Morero
150 kVA single phase pole mounted transformer e ile ea isoa Canada ka 2024. Matla a lekantsoeng a transformer ke 150 kVA e nang le pholiso ea ONAN. Motlakase o ka sehloohong ke 19.92 kV e nang le ± 2 * 2.5% tapping range (NLTC), motlakase oa bobeli ke 0.12 / 0.24 kV, ba thehile sehlopha sa vector sa Ii0.
One-phase pole mounted transformer ke mofuta oa transformer e sebelisoang haholo lits'ebetsong tsa kabo, e kengoang haholo lipalong tsa lisebelisoa. Mosebetsi oa eona o ka sehloohong ke ho fetola matla a motlakase a phahameng hore e be li-voltages tse tlase bakeng sa tšebeliso e sireletsehileng le e sebetsang ke bareki. Transformer ena e sebelisoa haholo marang-rang a kabo ea mahaeng le litoropong, haholo libakeng tse nang le tlhokahalo e tlase ea matla, joalo ka libaka tsa bolulo, temo le liindasteri tse nyane. Kaha -li-transformer tse palamisitsoeng li kentsoe lipalong tsa ts'ebeliso, li boloka sebaka sa fatše ka katleho 'me li fokotsa litšenyehelo tsa litšebeletso tse amanang le ho kenya lithapo. E na le lisebelisoa tsa ts'ireletso, li-transformer tsena li ka thibela lipotoloho tse khutšoane, li-overload le liphoso tse ling, ho matlafatsa ts'ireletso le ts'epahalo ea ts'ebetso.
