Calculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV (sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts). Convert watts to kilowatts by dividing the number of watts by 1,000.

P (kW) = (I (Amps) × V (Volts) × PF × 1.732) ÷ 1,000. As we can see, the electrical power in the 3-phase AC circuit depends on: I (Amps): Electrical current, measured in amps. The more amps

Approximate full load amperage of three-phase motors Table 2 presents the approximate full load current of three-phase motors with approximately 1450 rpm and 

Mar 01,  · For example, take a 400 V (V LL) three phase system with the following loads: phase 1 = 80 A, phase 2 = 70 A, phase 3 = 82 A the line to neutral (phase) voltage V LN = 400/√3 = 230 V phase 1 apparent power = 80 x 230 = 18,400 VA = 18.4 kVA phase 2 apparent power = 70 x 230 = 16,100 VA = 16.1 kVA

Rearrange the formula of hp to amps for the three-phase line-to-line system P = I * √3 * V * PF* η / 746; Apply the values (we can approximate the square root of 3 as 1.73 ), P = 0.5 * 1.73 * 100 * 0.8 * 95% / 746; The resulting power equals 0.088 hp; We can also rewrite the outcome using scientific notation, P = 8.8*10⁻² hp.

The formula states that power is equal to the square root of 3, power factor, voltage, and current. P = √3 * V * I * cosΦ. While. P : electrical three phase power. I : the current of the 3 phase load. V : phase to phase voltage of the power source. cosΦ : is the power factor of the load.

3-Phase Calculations. For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000.

How do you calculate motor current for a 3 phase and single phase motor? 3-phase motor amps calculation with power rating in kilowatt (kW): \(I=\displaystyle\frac{1000 \cdot P_{kW}}

3 Phase Induction Motor current calculator is used to calculate the rated and full load amperes of the motor. Enter the rated volts, amps, power, 

A 3 phase electric meter is essential for calculating the 3-phase motor amps calculation by heavy electrical appliances. It is recommended to use this energy meter only when your load requirement is more than 5 KW to 7 KW. For a load lower than this, a single-phase energy meter is sufficient and much more economically viable.

Power Factor- PF - three phase motors(0 - 1) RLA - "Running Load Amps"- current drawn during normal operation of electric motor. FLA - "Full Load Amps"- amount of current drawn when full-load torque and horsepower is reached for the motor. FLAis usually determined in laboratory tests. Note!- in the calculator above FLAis RLA + 25%. 1 hp = 0.745 kW
