How to calculate from power ( kW & HP ) to ampere ( I )? 1) Kilo watt (kW) to ampere ( I )įor 3 phase power supply kW = I x V x 1.732 x pfįor 1 phase power supply kW = I x V x pfĮxample : 1 unit compressor size rated 37 kw,415 VAC,3 phase and 80% pf,calculate the full load ampere?įirst we must convert from hp to kW using this formula :Īfter that use the formula kW to ampere :ġ unit induction motor power rated 25 hp,200 VAC,3 phase,90 % power factor,calculated the full load ampere. To convert amps to kilowatts the power formula can be used, which states that I P ÷ E, given that P is the power in watts, I is current in amps, and E is voltage in volts. Current (I): Enter the the current in Amperes (A). To adapt the power formula to using kilowatts, first start by converting kilowatts to watts, which can be done by multiplying the power in kilowatts by 1,000 to get the number of watts. Voltage (V): Enter the phase-to-phase () voltage for a 3-phase AC supply in volts. The power formula states that current power voltage. ![]() P (kW) 3 x PF x I (A) x V L-N (V) / 1000, which means that the power in Kilowatts. It is possible to convert kilowatts (kW) to amps using the Watt’s Law power formula. It means that the phase current in amps is computed by 1000. We cannot get the actual full load ampere because it depend on efficiency of motor.If electric motors have a higher efficiency rating,it will draw fewer amps, for example a 10 HP motor with a 60% efficiency rating will draw about 65 amps at 230 VAC compared to about 45 amps for a motor with a 80% rating. P (kW) 3 x PF x I (A) x V L-L (V) / 1000, which means that the power in Kilowatts is calculated by the square root of three multiplied by the power factor times the phase current in amps by the line to line voltage RMS. Calculation of AC three phase Kilowatts to amps. Three-phase current I(A) is equal to 1000 times of real power divided by the 3 times of multiplication of voltage between the line to neutral and power factor. This time i want share about how to calculated the full load ampere (FLA) of electric motor from their power rated.It not difficult if we know the right formula to get the answer.From this calculation we only can estimate the value of full load ampere. Note that you can also locate many conversions, including 1 kilowatts to amps, using the search form in the. In case of the three-phase electrical generation, line to line voltage and line to neutral voltage require different constants to convert 16 kilowatts to amps, ( 3 ) and 3, respectively. Finally, 1 kW to amps 120 volts 8.33, 16.67, 9.62 and 5.56 amperes. For alternating currents, the 16 kW amp transformation is different for a single phase and a 3 phase system the power factor is needed in both cases. Generally for electric motor size,it rated by horsepower (hp) or kilowatts (kW) unit.We can recognize the electric motor size when refer to their kilowatts or horsepower.So from power (kW/hp), how we can know the full load ampere for electric motor? For alternating currents, the 1 kW amp transformation is different for a single phase and a 3 phase system the power factor is needed in both cases. ![]()
