1.1 Tlhaloso ea Morero
300 kVA phase three phase mounted transformer e ile ea isoa Jamaica ka 2025. Matla a lekantsoeng a transformer ke 300 kVA e nang le pholiso ea ONAN. Motlakase oa mantlha ke 12GrdY/6.928 kV e nang le ± 2 * 2.5% tapping range (NLTC), motlakase oa bobeli ke 0.208 / 0.12 kV, ba thehile sehlopha sa vector sa YNyn0.
Moreki oa rona, e leng setsi sa masepala se sebeletsang sebaka se ntseng se hola ka potlako ho la US Pacific Northwest, se reka 300 kVA, 12kV 12kV three-phase three{{5} transformer e behoang bakeng sa boikitlaetso ba bohlokoa ba ho ntlafatsa grid. Yuniti ena e tla kengoa bohareng ba setereke se secha sa khoebo, se tla sebetsa e le setsi sa mantlha sa kabo ea motlakase bakeng sa motswako oa litsi tsa mabenkele, liofisi, le{7}}meaho ea malapa a mangata.
Morero ona o hlahisa liphephetso tse tharo tsa bohlokoa:
Ho Mamelleha ho Likhatello Tse Khethehileng tsa Tikoloho:Sebaka sena se na le ts'ebetso e kholo ea litšisinyeho tsa lefatše le lehloa le leholo mariha. Transformer e tlameha ho etsoa enjene ea ho mamella matla a tšisinyeho ea lefatše ea Zone 4 le lehloa le fihlang ho 150 PSF.

02 Tlhahiso
2.1 Konokono
Transformer ena-mohato oa bohlano-e hahiloe ka lishiti tsa tšepe tsa silicon tse pakiloeng hantle, e sa fokotseng-tahlehelo ea mojaro ka ho fihla ho 15% 'me e sebetsa hantle ho feta 99%. Motsoako oa eona o leka-lekaneng oa makenete o fokotsa hysteresis le tahlehelo ea hona joale ea eddy ka 10-20%, ha lerata la ts'ebetso le theoleloa ka 5-10 dB (A). Moralo o matla o ntlafatsa matla a mochini le ts'ebetso ea mocheso, ho boloka mocheso o ka tlase ho 65 K tlasa mojaro o felletseng bakeng sa bophelo bo atolositsoeng ba ts'ebeletso.
2.2 Ho tsubella
Transformer ena e sebelisa hybrid winding configuration, e kopantseng sebaka se phahameng sa-voltage (HV) le matsoelintsoeke a tlase{1}}le foil (LV) foil. HV winding e sebelisa terata e sirelelitsoeng hantle, e eketsang matla a ho koala le ho fokotsa matla a sebaka sa motlakase ka hoo e ka bang 15–20%, e netefatsa hore e sebetsa ka botšepehi tlas'a{5}maemo a matla a motlakase. Ho sa le joalo, matsoelintsoeke a LV a sebelisa foil e teteaneng, e ntlafatsang kabo ea hajoale le ho eketsa{7}}sekoere se mamellang matla a ho fihla ho 25% ha ho bapisoa le mapheo a tloaelehileng a terata. Moralo ona o boetse o ntlafatsa phallo ea mocheso, o fokotsa ho phahama ha mocheso oa hotspot ka likhato tse 10-15 le ho nolofatsa mekhoa ea ho kenya le ho e lokisa.
