Amps to kVA Calculator (single phase)
What is an Amps to kVA Calculator?
An amp to kVA calculator is a very useful tool in making rapid calculations for the conversion of ampere – electrical current to kilovolt-ampere – apparent power, or kVA. It helps workers engaged in electrical systems, especially those using single-phase and three-phase power configurations.
You can also Calculate Amps to kVA manually by using the following formula.
Formula for Single-Phase System
To calculate kVA from current (I) and voltage (V) in a single-phase system:
kVA = (I × V) / 1000
Where:
- I = Current in amps
- V = Voltage in volts
- kVA = Apparent power in kilovolt-amperes
Example Calculation for Single-Phase
If the current is 10 amps and the voltage is 240 volts:
kVA = (10 × 240) / 1000 = 2.4 kVA
Formula for Three-Phase System
To calculate kVA in a three-phase system:
kVA = (I × V × √3) / 1000
Where:
- I = Current in amps
- V = Voltage in volts
- √3 = Square root of 3, approximately 1.732
- kVA = Apparent power in kilovolt-amperes
Example Calculation for Three-Phase
If the current is 10 amps and the voltage is 240 volts:
kVA = (10 × 240 × √3) / 1000 ≈ 4.15 kVA
Why Use an Amps to kVA Calculator?
Using an Amps to kVA calculator provides:
- Fast Calculations: Instant results without the need for manual math.
- Accurate Load Planning: Helps identify the kVA requirements for different devices, ensuring circuits can handle the load.
- Safety and Efficiency: Prevents overloading, reducing the risk of electrical faults or system downtime.
What is Amps and kVA
- Amps (Amperes)Â measure the amount of electric current flowing through a conductor.
- kVA (Kilovolt-Amperes)Â measures the apparent power in an electrical circuit, combining both real power (in kW) and reactive power (in kVAR).
How to use Amps to kVA calculator?
- Enter the current in amps.
- Choose whether you’re calculating for Single-Phase or Three-Phase.
- For Single-Phase, input the voltage in volts.
- For Three-Phase, input the voltage and calculate using the √3 factor.
- Click “Calculate” to get the kVA result.
