In other words, the sum of the powers of the three phases is calculated to be exactly a constant value, in this instance 10,080.00 watts. The computations of Example 1 and Example 2 demonstrate one of the significant differences between a single phase motor and a three phase motor.

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.
Phasor representation simplifies circuit analysis when dealing with sinusoidal signals. Drop the time-harmonic (oscillatory) portion of the signal representation. Known and constant. Represent with rms amplitude and phase only. For example, consider the time-domain voltage expression.
3 phase power formula. The formula for calculating the power in a three-phase electrical circuit is: P= √3 ×VL×IL×cos (θ) Where: P is the power in watts (W). √3. is the square root of 3, approximately 1.732. VL . is the line-to-line voltage in volts (V). IL . is the line current in amperes (A).
