How This Calculator Works
This calculator converts apparent power (KVA) to current (Amps) for both single-phase and three-phase electrical systems.
Key Concepts:
- Apparent Power (KVA): The combination of real power (KW) and reactive power (KVAR)
- Current (Amps): The flow of electric charge through a conductor
- Voltage (V): The electrical potential difference
Formulas Used:
Single Phase:
$$ I = \frac{KVA \times 1000}{V} $$
$$ I = \frac{KVA \times 1000}{V} $$
Three Phase:
$$ I = \frac{KVA \times 1000}{V \times \sqrt{3}} $$ $$ \text{Where } \sqrt{3} \approx 1.732 $$
$$ I = \frac{KVA \times 1000}{V \times \sqrt{3}} $$ $$ \text{Where } \sqrt{3} \approx 1.732 $$
Example Calculation
Single Phase Example:
Given: 5 KVA at 230V
$$ I = \frac{5 \times 1000}{230} $$ $$ I = \frac{5000}{230} $$ $$ I = 21.74 \text{ Amps} $$
$$ I = \frac{5 \times 1000}{230} $$ $$ I = \frac{5000}{230} $$ $$ I = 21.74 \text{ Amps} $$
Three Phase Example:
Given: 15 KVA at 400V
$$ I = \frac{15 \times 1000}{400 \times \sqrt{3}} $$ $$ I = \frac{15000}{400 \times 1.732} $$ $$ I = \frac{15000}{692.8} $$ $$ I = 21.65 \text{ Amps} $$
$$ I = \frac{15 \times 1000}{400 \times \sqrt{3}} $$ $$ I = \frac{15000}{400 \times 1.732} $$ $$ I = \frac{15000}{692.8} $$ $$ I = 21.65 \text{ Amps} $$
