Cómo convertir la potencia aparente en kilovoltios-amperios (kVA) a amperios (A) coiente eléctrica en amperios (A).
Puedes calcular amperios a partir de kilovoltios-amperios y voltios, but you can't convert kilovolt-amps to amps scoiente eléctrica ence kilovolt-amps and amps units do not measure the same quantity.
The phase current I coiente eléctrica en amps is equal to 1000 times the apparent power S in kilovolt-amps, divided by the RMS voltage V in voltios:
I(A) = 1000 × S(kVA) / V(V)
So amps are equal to 1000 times kilovolt-amps divided by voltios.
amps = 1000 × kVA / voltios
o
A = 1000 kVA / V
Question: What is the phase current coiente eléctrica en amps when the apparent power is 3 kVA and the RMS voltage supply is 110 voltios
Solución:
I = 1000 × 3kVA / 110V = 27.27A
The phase current I coiente eléctrica en 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 voltios:
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 voltios.
amperios = 1000 × kVA / (3 × voltios)
o
A = 1000 kVA / (3 × V)
Question: What is the phase current coiente eléctrica en amps when the apparent power is 3 kVA and the line to line RMS voltage supply is 190 voltios
Solución:
I = 1000 × 3kVA / (3 × 190V) = 9.116A
The phase current I coiente eléctrica en 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 voltios:
I(A) = 1000 × S(kVA) / (3 × VL-N(V) )
So amps are equal to 1000 times kilovolt-amps divided by 3 times voltios.
amperios = 1000 × kVA / (3 × voltios)
o
A = 1000 kVA / (3 × V)
Question: What is the phase current coiente eléctrica en amps when the apparent power is 3 kVA and the line to neutral RMS voltage supply is 120 voltios
Solución:
I = 1000 × 3kVA / (3 × 120V) = 8.333A
