1.1 Tlhaloso ea Morero

The 500 kVA three-phase pad-transformer mounted, e rometsoeng USA ka 2024, e entsoe ho kopana le IEEE Std C57.12.34-2022 le DOE 2016 maemo a sebetsang hantle.

E sebetsa ho 60 Hz, e na le motlakase oa mantlha oa 24 kV le motlakase oa bobeli oa 480GrdY/277 V ka sehlopha sa li-vector Dyn1. Theutility pad mounted transformere sebelisa li- windings tsa koporo le pholileng ea KNAN, e tletseng oli ea ester ea tlhaho ea FR3 bakeng sa ts'ireletso e ntlafetseng ea mollo le ho lumellana le tikoloho. E kenyelletsa bokhoni ba loop feed, phihlello e shoeleng-ka pele, le ho se{3}}changer ea ho roala thepa e nang le ±2 × 2.5% ea phetoho ea motlakase. Ka ho sa khonehe ho 5.75%, ha ho{8}}tahlehelo ea mojaro oa 0.610 kW, 'me{10}ka tahlehelo ea mojaro oa 4.530 kW, yuniti ena e fana ka kabo ea motlakase o sebetsang hantle le e tšepahalang{12}}ea motlakase oa mahareng. E loketse ho sebelisoa litsing tsa khoebo, libaka tsa indasteri tse nyane, le nts'etsopele ea bolulo moo ho hlokahalang phetoho e bolokehileng, e tsitsitseng le e sebetsang hantle.
