![]() ![]() Kilowatts = the square root of 3 times volts times the power facto divided by 1,000Ĭalculate the power consumption by an electrical appliance, given that its RMS voltage is 110V, its phase current is 4A and that the power factor is 0.9. P (kW) = √3 × PF × I (A) × V L-L(V) / 1000 Here’s the 3-phase power equation: P (kW) (I (Amps) × V (Volts) × PF × 1. Real Power P, in kilowatts in an AC 3 phase circuit is calculated by multiplying the square root of 3 by the phase current I, in amps (A) multiplied by the power factor PF, multiplied by the line in line RMS V L-L voltage, in volts (V), and the dividing the result by 1,000. P = 0.9 × 4A × 110V / 1000 = 0.396kW AC three phase amps to kilowatts conversion Assumed the PF is 0.5, and supposed the voltage is 110 V, we get these result: DC: I 1000 × 6 kW / 110 V 54.55 A. ![]() Given that the phase current in a circuit is 4A, the power factor is 0.9 and the RMS voltage is 110V, calculate the actual power consumption in the circuit. From our formulas follows that in order to get 6 kilowatts in amps we must know the voltage. ![]() Kilo-watts = amps times volts times the power factor divided by 1,000. P = 2A × 110V / 1000 = 0.22kW AC single phase amps to kilowatts conversionĪctual power P, in kilowatts is calculated by multiplying the phase current I in amps (A) by the power factor PF, multiplied by the RMS voltage V, in volts (V), and then dividing the result by 1,000. Assumed the PF is 0.5, and supposed the voltage is 110 V, we get these result: DC: I 1000 × 125 kW / 110 V 1136.36 A. Work out the power consumption in an electrical circuit where the voltage supply is 110V and the current is 2A. From our formulas follows that in order to get 125 kilowatts in amps we must know the voltage. Assumed the PF is 0.5, and supposed the voltage is 110 V, we get these result: AC, Three Phase, Line to Line Voltage: I 1000 × 100 kW / ( 3 × 0.5 × 110 V) 1049.73 A. Don’t let all the symbols scare you off using this equation once you put all the relevant pieces into the equation, it’s easy to use. From our formulas follows that in order to get 100 kilowatts in amps we must know the voltage. Kilowatts are calculated by multiplying the volts by amps and then dividing by 1,000. P 3 × pf × I × V This simply states that the power is the square root of three (around 1.732) multiplied by the power factor (generally between 0.85 and 1, see Resources), the current and the voltage. Multiply the corresponding voltage according to the formula by the power factor and by the root of three. For example, if you have a refrigerator that consumes 1.2kW, you must multiply 1,2 × 1000, obtaining 1200, (1,2 × 1000) 1200. The power P, in kW is calculated by multiplying the voltage V in volts (V) by the phase current I, in amps (A) and then dividing the result by 1,000. How to convert from kW to Amperes in just 3 steps: Multiply the kW by 1000. Current (I): Enter the the current in Amperes (A). How to convert electric current in amps (A) to electric power in kilowatts (kW) DC amps to kilowatts conversion Voltage (V): Enter the phase-to-phase () voltage for a 3-phase AC supply in volts. ![]()
