I(A) = P (W) / (PF x V (V) = 186 W/ (0.4 X 110 V) = 2.943 amps (A) Calculating the AC three phase watts to amps Line to line Voltage I (A) = P (W) / (√3 x PF x V L-L (V)), which means that the phase current in amps is computed by dividing the real power in watts by the multiplication of square root of three, time the power factor. 1000kW. 10,417 A. 5,208.3 A. Kw to amps is a kilowatts to amps conversion Thefollowing formulas can be used to calculate the capacitance of a capacitor in farad and microfarad for power factor correction. C = 159.155 x 106 x Q in kVAR ÷ f x V2 in microfarad. C = 159.155 x Q in kVAR ÷ f x V2 in Farad. or. C = kVAR x 109 ÷ (2π x f x V2) in microfarad. C = kVAR x 103 ÷ (2π x f x V2) in Farad. 35 kW to Amps Conversion. From our formulas follows that in order to get 3.5 kilowatts in amps we must know the voltage. Assumed the PF is 0.5, and supposed the voltage is P=. 3 * 277 * 25 * (90/100) * 0.9 746. = 22.56HP. HP to Amps or Amps to HP calculator are mainly used for motor circuits. HP is used to express output power and Amps expresses full load Amps or rated input current. A45 kW motor would draw about 55 kW from the supply with a power factor of 0.85, so that is 65 kVA, and on a 415 v 3-phase supply that is a current of 90 amps. Aheater is a device that protects a motor from thermal overloads due to excess current in the windings. According to the NEC, the overload rating must not exceed 115% of the full-load current of the motor. For example, the full-load current of a 10 HP motor at 230V is 28 Amps. Therefore, the heater must be sized for 28 * 1.15 = 32.2 Amps. Whenthe power factor is 1.0 (unity) or 100%, the phase angle between the current and the voltage will be 0° because cos⁻¹(1.0) = 0°. When the power factor equals zero (0), the phase angle is 90° due to the formula cos⁻¹(0) = 90°. The higher the power factor, the more efficient the system will be. .
