What is the kVA to Amps Calculator?
The kva to amps calculator is a free online tool that helps you work out kva to amps quickly and accurately. It uses the standard formula 3ph: I = kVA x 1000 / (sqrt(3) x V); 1ph: I = kVA x 1000 / V and shows the result instantly as you type, along with a full breakdown so you can see exactly how the answer was reached.
How to use this calculator
- Enter kVA.
- Enter voltage.
- Choose phase.
- See the current.
Formula used
3ph: I = kVA x 1000 / (sqrt(3) x V); 1ph: I = kVA x 1000 / VExplanation of each input
- Apparent power (kVA) โ the apparent power used in the calculation.
- Voltage (V) โ the voltage used in the calculation.
- Supply โ the supply used in the calculation.
Understanding your result
- Current โ the calculated current in A.
Step-by-step calculation
For the example values 10 kVA, 415V, 3ph:
- Apply the formula:
3ph: I = kVA x 1000 / (sqrt(3) x V); 1ph: I = kVA x 1000 / V - Substitute the values: 10000/(1.732x415)
- Result: about 13.9 A
Worked example
| Inputs | 10 kVA, 415V, 3ph |
|---|---|
| Working | 10000/(1.732x415) |
| Result | about 13.9 A |
