3-Phase Power Formula. Here’s the simple formula we use to calculate power on a 1-phase AC circuit: P (kW) = I (Amps) × V (Volts) ÷ 1,000. Basically, we just multiply amp by volts. The ‘1,000’ factor is there to convert from W to kW; we want the resulting power to be in kilowatts. 1 kW = 1,000W.
This calculator estimates the crucial full load amps (FLA) your motor will draw at its rated horsepower. Enter the motor’s voltage (line-to-line voltage between any two phases) and horsepower. For a more precise calculation, include the motor’s efficiency (typically 90-95%).

14 mar 2016 · Three Phase Load Calculating kVA and kW (Three Phase) Formula: kVA = V x I x √3 ÷ 1000 Where: V = Volts generated I = Amps available P.F. - Power factor of load (Usually 0.8) √3 = 1.732. To calculate the current (Amps) I = kVA x 1000 ÷ V x √3. three-phase-load-calculator.xls (770 KB)
Formula for 3-Phase Motor Amperage: Amperage (A) = (√3 * Power (kW)) / (Voltage (V) * Power Factor * Efficiency) Where: A is the amperage in amps (A). √3 is the square root of 3 (approximately 1.732). Power is the motor power rating in kilowatts (kW). Voltage is the supply voltage in volts (V).
A three-phase power calculator is your best buddy for determining power consumption and efficiency in three-phase systems. It’s like having a super-smart assistant who crunches numbers so you don’t have to. Here’s the lowdown on how it works: Inputs for the Calculator. Line Voltage (V_L): The voltage between any two phases.
