Cómo convertir coiente eléctrica en amperios (A) to apparent power en kilovolt-amps (kVA).
Puedes calcular kilovoltio-amperios a partir de amperios y voltios, but you can't convert amps to kilovolt-amps sence kilovolt-amps and amps units do not measure the same quantity.
The apparent power S en kilovolt-amps is equal to phase current I in amps, times the RMS voltage V in voltios, divided by 1000:
S(kVA) = I(A) × V(V) / 1000
Po lo tanto, los kilovoltio-amperios son iguales a amps times voltios divided by 1000.
kilovoltio-amperios = amps × voltios / 1000
o
kVA = A × V / 1000
What is the apparent power en kVA when the phase current is 12A and the RMS voltage supply is 110V
Solución:
S = 12A × 110V / 1000 = 1.32kVA
The apparent power S en 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 en voltios, divided by 1000:
S(kVA) = 3 × I(A) × VL-L(V) / 1000
Po lo tanto, los kilovoltio-amperios son iguales a 3 times amps times voltios divided by 1000.
kilovoltio-amperios = 3 × amps × voltios / 1000
o
kVA = 3 × A × V / 1000
What is the apparent power en kVA when the phase current is 12A and the line to line RMS voltage supply is 190V
Solución:
S = 3 × 12A × 190V / 1000 = 3.949kVA
The apparent power S en 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 en voltios, divided by 1000:
S(kVA) = 3 × I(A) × VL-N(V) / 1000
Po lo tanto, los kilovoltio-amperios son iguales a 3 times amps times voltios divided by 1000.
kilovoltio-amperios = 3 × amps × voltios / 1000
o
kVA = 3 × A × V / 1000
What is the apparent power en kVA when the phase current is 12A and the line to neutral RMS voltage supply is 120V
Solución:
S = 3 × 12A × 120V / 1000 = 4.32kVA
