변환 방법 전류 의 암페어(A) to apparent power 의 kilovolt-amps (kVA).
암페어와 볼트, but you can't convert amps to kilovolt-amps s의ce kilovolt-amps and amps units do not measure the same quantity.
The apparent power S 의 kilovolt-amps is equal to phase current I in amps, times the RMS voltage V in 볼트, divided by 1000:
S(kVA) = I(A) × V(V) / 1000
따라서 킬로볼트암페어는 amps times 볼트 divided by 1000.
킬로볼트암페어 = amps × 볼트 / 1000
또는
kVA = A × V / 1000
What is the apparent power 의 kVA when the phase current is 12A and the RMS voltage supply is 110V
해답:
S = 12A × 110V / 1000 = 1.32kVA
The apparent power S 의 kilovolt-amps (with balanced loads) is equal to square root of 3 times the phase current I in amps, times the line to line RMS voltage VL-L 의 볼트, divided by 1000:
S(kVA) = 3 × I(A) × VL-L(V) / 1000
따라서 킬로볼트암페어는 3 times amps times 볼트 divided by 1000.
킬로볼트암페어 = 3 × amps × 볼트 / 1000
또는
kVA = 3 × A × V / 1000
What is the apparent power 의 kVA when the phase current is 12A and the line to line RMS voltage supply is 190V
해답:
S = 3 × 12A × 190V / 1000 = 3.949kVA
The apparent power S 의 kilovolt-amps (with balanced loads) is equal to 3 times the phase current I in amps, times the line to neutral RMS voltage VL-N 의 볼트, divided by 1000:
S(kVA) = 3 × I(A) × VL-N(V) / 1000
따라서 킬로볼트암페어는 3 times amps times 볼트 divided by 1000.
킬로볼트암페어 = 3 × amps × 볼트 / 1000
또는
kVA = 3 × A × V / 1000
What is the apparent power 의 kVA when the phase current is 12A and the line to neutral RMS voltage supply is 120V
해답:
S = 3 × 12A × 120V / 1000 = 4.32kVA
