Как преобразовать кажущуюся мощность в киловольт-амперах (кВА) в амперах (А) электрический ток в амперах (А).
Вы можете рассчитать амперы из киловольт-ампер и вольт, but you can't convert kilovolt-amps to amps sэлектрический ток вce kilovolt-amps and amps units do not measure the same quantity.
The phase current I электрический ток в amps is equal to 1000 times the apparent power S in kilovolt-amps, divided by the RMS voltage V in вольт:
I(А) = 1000 × S(кВА) / V(В)
So amps are equal to 1000 times kilovolt-amps divided by вольт.
amps = 1000 × kVA / вольт
или
А = 1000 кВА / В
Question: What is the phase current электрический ток в amps when the apparent power is 3 kVA and the RMS voltage supply is 110 вольт
Решение:
I = 1000 × 3кВА / 110В = 27,27А
The phase current I электрический ток в 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 вольт:
I(А) = 1000 × S(кВА) / (3 × VL-L(В) )
So amps are equal to 1000 times kilovolt-amps divided by the square root of 3 times вольт.
амперы = 1000 × кВА / (3 × вольт)
или
А = 1000 кВА / (3 × В)
Question: What is the phase current электрический ток в amps when the apparent power is 3 kVA and the line to line RMS voltage supply is 190 вольт
Решение:
I = 1000 × 3кВА / (3 × 190В) = 9.116А
The phase current I электрический ток в 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 вольт:
I(А) = 1000 × S(кВА) / (3 × VL-N(В) )
So amps are equal to 1000 times kilovolt-amps divided by 3 times вольт.
амперы = 1000 × кВА / (3 × вольт)
или
А = 1000 кВА / (3 × В)
Question: What is the phase current электрический ток в amps when the apparent power is 3 kVA and the line to neutral RMS voltage supply is 120 вольт
Решение:
I = 1000 × 3кВА / (3 × 120V) = 8.333A
