Choosing the right generator for your project starts with determining the power required. But what exactly does kVA mean, and how do you know how much you need?
In this article, we explain what kVA is, how to calculate it, and how we at Trime North can help you make the right choice.
What is kVA?
kVA stands for kilovolt amps and indicates the so-called apparent power. This is a combination of two elements:
- Voltage (volts)
- Current (amps)
Unlike kVA, kW indicates actual power.
How do you calculate kVA?
To calculate the power of your installation, use the following formula:
P (power) = U (volts) x I (amps) x √3(or 1.73) x Cos Phi
An example: Suppose you have a 3-phase 400-volt motor with a current of 25.18 amps and a cos phi of 0.8.
Then you get:
P = 400V x 25.18A x √3(or 1.73) x 0.8 = ± 14kW
This means you need a generator with an output of about 20 kVA to run this motor efficiently.
Why is this important?
Calculating the power required is essential to ensure that your equipment functions optimally. Too little or just too much load can lead to problems and unnecessarily high repair costs.
