1.1 Tlhaloso ea Morero

Transformer ea 315 kVA e bulang matsoelintsoeke ea mofuta o omileng e ile ea isoa Afrika Boroa ka 2025. Matla a lekantsoeng a 315 kVA e nang le pholiso ea AN/AF, motlakase oa mantlha ke 11 kV le ±2*2.5% tapping range (NLTC), motlakase oa bobeli ke 0.55kV, ba thehile sehlopha sa vector ea Dyn11.

Sehlahisoa sena ke mofuta o bulehileng-, oa mofuta oa H o omileng-mofuta oa transformer o entsoeng ka theknoloji e tsoetseng pele ea Vacuum Pressure Impregnation (VPI), e etselitsoeng haholo maemo a thata a indasteri. Maqhubu a eona a etsa liphekolo tse ngata tsa VPI ho theha sekhahla se teteaneng sa H, se fanang ka khanyetso e ikhethang ho mongobo, lerōle le kutu. E hlophisitsoe ka lisebelisoa tsa ho kenya letsoho tsa Sehlopha sa H le ho phahama ha mocheso ka 100K, e fana ka moeli o moholo oa mocheso, e netefatsa bophelo bo atolositsoeng ba ts'ebeletso le matla a holimo a holimo le tlas'a{5}}maemo a phahameng a mocheso.

2.1 Ntlha ea bohlokoa

Moko o hahiloe ka-ka letlapa la tšepe la boleng bo holimo- le entsoeng ka silicon. Sesebediswa sena se khethehileng se entsoe ka laminated ka hloko le ho lemala ho fokotsa tahlehelo ea mantlha le ho eketsa ts'ebetso ea makenete. Mabele a eona-sebopeho se shebaneng le sona se fokotsa haholo hysteresis le tahlehelo ea hona joale ea eddy, e netefatsa hore matla a khoheli a khona ho kenella ka matla 'me ha a sebelisoe{5}karolo e tlase. Boenjineri bo nepahetseng ba mantlha bo thusa ho sebetsa hantle haholo ha transformer, ho sebetsa ha lerata le tlase, le ho boloka matla ka kakaretso-.

2.2 Ho tsubella
