kVA to Amps Calculator Overview
The kVA to Amps Calculator converts apparent power measured in kilovolt-amperes (kVA) into current measured in amperes (A). It supports both single-phase and three-phase electrical systems. This calculator helps electricians, engineers, and students quickly find the current flowing through a circuit by simply inputting the kVA rating and system voltage. It is especially useful for designing electrical systems, sizing conductors, and ensuring safe load capacities. The tool is accurate for 50Hz and 60Hz systems and requires no complex inputs like power factor unless converting to real power (kW). Whether for residential or industrial applications, this calculator simplifies your electrical calculations and saves time.
Sample kVA to Amps Canversion Table
| System | kVA | Voltage (V) | Current (Amps) |
|---|---|---|---|
| Single-phase | 5 | 230 | 21.74 |
| Three-phase | 10 | 400 | 14.43 |
| Three-phase | 15 | 415 | 20.90 |
Frequently Asked Questions - kVA to Amps Calculator:
How do you convert kVA to amps?
Amps = (kVA × 1000) ÷ Voltage for single-phase; for three-phase use Amps = (kVA × 1000) ÷ (√3 × Voltage).
What is the formula for 3-phase kVA to amps?
Amps = (kVA × 1000) ÷ (√3 × Voltage).
Do I need power factor to convert kVA to amps?
No, power factor is not needed for kVA to amps conversion.
Is this calculator accurate for industrial use?
Yes, it provides reliable estimations for electrical load sizing.
Does frequency affect the conversion?
No, frequency does not affect the kVA to amps calculation.
Can I use this for transformer sizing?
Yes, it's commonly used to estimate transformer load currents.
What is kVA?
kVA stands for kilovolt-amperes, a unit of apparent power.
What's the difference between kVA and kW?
kW is real power; kVA includes reactive power and is apparent power.
Can amps be converted back to kVA?
Yes, kVA = (Amps × Voltage) ÷ 1000.
Is this tool suitable for solar systems?
Yes, it helps calculate current for solar inverters and generators.
