DC ボルトからキロワットへの計算式

したがって、キロワット (kW) 単位の電力 P は、ボルト (V) 単位の電圧 V にアンペア (A) 単位の電流 I を掛けて [1000] で割った値に等しくなります。

P(kW) = V(V) × I(A) / 1000

例 1

電流が 3A で供給電圧が 25V の場合の消費電力は何キロワットですか?

電力 P は、電流 3 アンペア×電圧 25 ボルトを 1000 で割った値に等しくなります。

P = 25V × 3A / 1000 = 0.075 kW

例 2

電流が 3A で供給電圧が 150V の場合の消費電力は何キロワットですか?

電力 P は、電流 3 アンペア×電圧 150 ボルトを 1000 で割った値に等しい。

P = 150V × 3A / 1000 = 0.45 kW

AC 単相ボルトからキロワットへの計算式

したがって、キロワット (kW) 単位の電力 P は、 力率  PF にアンペア (A) 単位の電流 I を掛け、ボルト (V) 単位の電圧 V を掛けて [1000] で割った値に等しくなります。

P(kW) = PF × I(A) × V(V) / 1000

例 1

力率が 0.8、相電流が 3A、RMS 電圧供給が 120V の場合の消費電力は何キロワットですか?

The power  P is equal to power factor of 0.8 times current of 3 amps times voltage of 120 volts divided by 1000.

P = 0.8 × 3A × 120V / 1000 = 0.288 kW

Example 2

What is power consumption in kilowatts when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 150V?

The power  P is equal to power factor of 0.8 times current of 3 amps times voltage of 150 volts divided by 1000.

P = 0.8 × 3A × 150V / 1000 = 0.36 kW

AC three phase volts to kilowatts calculation formula

The power  P in kilowatts (kW) is equal to square root of 3 times the power factor  PF times the current  I in amps (A), times the line to line RMS voltage  VL-L in volts (V) divided by 1000:

P(kW) = 3 × PF × I(A) × VL-L(V) / 1000

            ≈ 1.732 × PF × I(A) × VL-L(V) / 1000

Example 1

What is power consumption in kilowatts when the power factor is 0.8 and the phase current is 3A and the voltage supply is 120V?

The power  P is equal to power factor of  0.8 times current of 3 amps times the voltage of 120 volts divided by 1000.

P(kW) = 3 × 0.8 × 3A × 120V / 1000 = 0.498kW

Example 2

What is power consumption in kilowatts when the power factor is 0.8 and the phase current is 3A and the voltage supply is 150V?

The power  P is equal to power factor of  0.8 times current of 3 amps times the voltage of 150 volts divided by 1000.

P(kW) = 3 × 0.8 × 3A × 150V / 1000 = 0.623kW
