キロボルトアンペア(kVA)で表される皮相電力を 電流に変換する方法 アンペア(A)で表される アンペア(A).
キロボルトアンペアと ボルト, but you can't convert kilovolt-amps to amps sアンペア(A)で表されるce kilovolt-amps and amps units do not measure the same quantity.
The phase current I アンペア(A)で表される amps is equal to 1000 times the apparent power S in kilovolt-amps, divided by the RMS voltage V in ボルト:
I(A) = 1000 × S(kVA) / V(V)
So amps are equal to 1000 times kilovolt-amps divided by ボルト.
amps = 1000 × kVA / ボルト
または
A = 1000 kVA / V
Question: What is the phase current アンペア(A)で表される amps when the apparent power is 3 kVA and the RMS voltage supply is 110 ボルト
解答:
I = 1000 × 3kVA / 110V = 27.27A
The phase current I アンペア(A)で表される amps is equal to 1000 times the apparent power S in kilovolt-amps, divided by the square root of 3 times the line to line RMS voltage V in ボルト:
I(A) = 1000 × S(kVA) / (3 × VL-L(V) )
So amps are equal to 1000 times kilovolt-amps divided by the square root of 3 times ボルト.
アンペア = 1000 × kVA / (3 × ボルト)
または
A = 1000 kVA / (3 × V)
Question: What is the phase current アンペア(A)で表される amps when the apparent power is 3 kVA and the line to line RMS voltage supply is 190 ボルト
解答:
I = 1000 × 3kVA / (3 × 190V) = 9.116A
The phase current I アンペア(A)で表される amps is equal to 1000 times the apparent power S in kilovolt-amps, divided by 3 times the line to line RMS voltage V in ボルト:
I(A) = 1000 × S(kVA) / (3 × VL-N(V) )
So amps are equal to 1000 times kilovolt-amps divided by 3 times ボルト.
アンペア = 1000 × kVA / (3 × ボルト)
または
A = 1000 kVA / (3 × V)
Question: What is the phase current アンペア(A)で表される amps when the apparent power is 3 kVA and the line to neutral RMS voltage supply is 120 ボルト
解答:
I = 1000 × 3kVA / (3 × 120V) = 8.333A
