# How do you calculate 3 phase load current?

## 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?

kVA to Amps Conversion Chart

6.3 kVA 5 kW 16.5 A
9.4 kVA 7.5 kW 24.7 A
12.5 kVA 10 kW 32.8 A
18.7 kVA 15 kW 49.1 A

## How many kVA is 20hp?

Equivalent Horsepower and kVA Ratings

HP kVA
9 HP 8.39 kVA
10 HP 9.33 kVA
15 HP 13.99 kVA
20 HP 18.65 kVA

How do you convert HP to amps?

How to Convert Horsepower to Amps

1. Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
2. Watts = Horsepower × 746.
3. Watts = Wattsη
4. Amps = Watts ÷ Volts.
5. 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

1. S(kVA) = √3 × I(A) × VL-L(V) / 1000.
2. So kilovolt-amps are equal to √3 times amps times volts divided by 1000.
3. kilovolt-amps = √3 × amps × volts / 1000.
4. kVA = √3 × A ⋅ V / 1000.
5. S = √3 × 12A × 190V / 1000 = 3.949kVA.
