Ntxiv mus, nyob rau hauv fais fab nroj tsuag, lub hwj chim factor yog 1 yog li ntawd MW is equal to MVA …… (MW=MVA x P.f).
Koj hloov MVA rau amps li cas?
Xaiv 3 theem amps, lossis "I", siv tus qauv: I=(MVA x 1, 000, 000)/(Vphase x 1.732) Tus 1, 000, 000 sawv cev rau "mega" qhov twg 1 megavolt yog 1,000,000 volts. Ntxiv nrog rau qhov piv txwv: I=(25 x 1, 000, 000)/(4, 000 x 1.732)=25, 000, 000/6, 928=3608.5 amps.
generator MVA txhais li cas?
Lub peev xwm ntawm lub tshuab hluav taws xob synchronous yog sib npaug ntawm cov khoom ntawm qhov hluav taws xob ib theem, tam sim no ib theem, thiab tus lej ntawm theem. Nws yog ib txwm teev nyob rau hauv megavolt-amperes (MVA) rau cov tshuab hluav taws xob loj lossis kilovolt-amperes (kVA) rau cov tshuab hluav taws xob me.
MVA unit yog dab tsi?
Volt amperes yog ib chav siv los piav txog cov khoom hluav taws xob hauv engineering. Volt amperes tuaj yeem sau luv VA. … Yog li ntawd, nws yuav siv 1,000 kilo-volt amperes kom tau ib qho mega-volt ampere Faib tus naj npawb ntawm kVA los ntawm 1,000 los hloov mus rau MVA. Piv txwv li, yog tias koj muaj 438 kVA, faib 438 los ntawm 1,000 kom tau 0.438 MVA.
MW MVA MVAR yog dab tsi?
MVA - MEGA VOLT AMPERE MW - MEGA WATT MVAR - MEGA VOLT AMPERE REACTIVE.
