How do you calculate 3 phase load current?
For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000. Again, assuming unity PF and solving this equation for “I,” you get: I = 1,000kW ÷ 1.732V.
How many kVA is 15 horsepower?
HP to kVA Conversion Chart:
HP | kVA |
---|---|
15 | 12.79 |
20 | 17.44 |
30 | 25.58 |
50 | 43.02 |
How do you calculate the power of a 3 phase motor?
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).
How many kVA is 15 amps?

How do you convert HP to amps?
How to Convert Horsepower to Amps
- Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
- Watts = Horsepower × 746.
- Watts = Wattsη
- Amps = Watts ÷ Volts.
- Amps = HP × 746V × η × PF.
How do you calculate motor load capacity?
When calculating motor loads, you need to know how to convert a motor’s current rating (given in amps) to a VA rating. To do this, multiply the motor’s nameplate amperage by the supply voltage.
How do you calculate load carrying capacity of a motor?
If you know the out put specifications of the motor & rated speed its easy calculate the Load that you can put on it. Power = 2*PI*N*. T/4500. where as torque is equal to Load multiplied by distance at which Load is applied.
How do you convert 3 phase kVA to amps?
3 phase amps to kVA calculation formula
- S(kVA) = √3 × I(A) × VL-L(V) / 1000.
- So kilovolt-amps are equal to √3 times amps times volts divided by 1000.
- kilovolt-amps = √3 × amps × volts / 1000.
- kVA = √3 × A ⋅ V / 1000.
- S = √3 × 12A × 190V / 1000 = 3.949kVA.
