What is Amps to kVA calculator (Three phase)

An Amps to kVA calculator is a three-phase converter calculator that converts the current in amps to apparent power in kilovolt-amperes. In any three-phase system, kVA can be calculated using current in amps and voltage in volts between three phases. The result will give an approximation of the total amount of apparent power being drawn from the system.

Yo can convert amps to kV. using the following formula

Formula for Three-Phase System (Line-to-Line Voltage)

To calculate kVA from current (I) and line-to-line voltage (V_L-L) in a three-phase system:

    kVA = (√3 × I × V_L-L) / 1000

Where:

I = Current in amps
V_L-L = Line-to-line voltage in volts
√3 ≈ 1.732 (constant for three-phase systems)
kVA = Apparent power in kilovolt-amperes

Example Calculation for Line-to-Line Voltage

If the current is 10 amps and the line-to-line voltage is 400 volts:

    kVA = (√3 × 10 × 400) / 1000 ≈ 6.93 kVA

Formula for Three-Phase System (Line-to-Neutral Voltage)

To calculate kVA from current (I) and line-to-neutral voltage (V_L-N) in a three-phase system:

    kVA = (3 × I × V_L-N) / 1000

Where:

I = Current in amps
V_L-N = Line-to-neutral voltage in volts
3 = Constant for three-phase systems with line-to-neutral voltage
kVA = Apparent power in kilovolt-amperes

Example Calculation for Line-to-Neutral Voltage

If the current is 10 amps and the line-to-neutral voltage is 230 volts:

    kVA = (3 × 10 × 230) / 1000 = 6.90 kVA

How to Use the Amps to kVA Calculator

Step 1: Choose the voltage type (Line-to-Line or Line-to-Neutral) from the dropdown menu.
Step 2: Enter the current in amps (I) in the “Current” input field.
Step 3: Enter the voltage in volts (V) based on your selection:
- For Line-to-Line voltage, enter the line-to-line voltage.
- For Line-to-Neutral voltage, enter the line-to-neutral voltage.
Step 4: Click the “Calculate” button to get the result in kVA.
Step 5: View the result and the detailed calculation breakdown displayed below the button.

That’s it! You can use the calculator for both Line-to-Line and Line-to-Neutral voltage types.
