01 Kakaretso
1.1 Semelo sa Morero
Sebopeho sa 75 kVA pad mounted transformer se ile sa isoa Amerika ka 2024. Matla a lekantsoeng a transformer ke 75 kVA e nang le pholiso ea ONAN. Motlakase oa mantlha ke 22.86GRDY/13.2kV e nang le ± 2 * 2.5% tapping range (NLTC), motlakase oa bobeli ke 0.48y / 0.208kV, ba thehile sehlopha sa vector sa YNyn0, 'me ke lijo tsa loop le transformer e ka pele e shoeleng. Lebokose la li-transformer tse kentsoeng ka mekhahlelo e meraro tse hlahisitsoeng ke SCOTECH haholo-holo li entsoe ka setsi, liphanele tse mahlakoreng, likaroloana, mamati le likoahelo tse kaholimo. Lebokose le arotsoe ka kamoreng ea khatello e phahameng, kamore ea transformer le kamore e tlaase ea khatello. Mohaho o phahameng oa motlakase o sebelisa moralo o phethahetseng oa khokahanyo, o nang le tšebetso e matla e thibelang{14}mesebetsi e sa sebetseng hantle, e ts'epahalang haholo, ho hlokomeloa ha bonolo, switchgear ea motlakase e phahameng e ka sebelisoa terminal load switch, ring network switchgear joalo-joalo. Kamore ea transformer e ka kengoa ka oli{16}}transformer e qoelitsoeng kapa e omeletseng, 'me e na le letlooa le sireletsang motho a le mong, phaposi ea transfoma e ka amohela moea oa tlhaho kapa moea o qobelloang, ho latela tlhoko ea ho kenya mochine o laolang mocheso, ho hlahloba mocheso oa kamore le sesebelisoa sa moea o ikemetseng. The low{18}voltage chamber e na le distribution, metering, reactive power compensation and other standard schemes, mme e ka etsa the secondary control loop le palo ea lithapo ho ea ka litlhoko.
