2. Select Voltage Type (For 3-phase): If you selected 3-phase, specify the voltage type (Line to Line or Line to Neutral).
3. Enter Amperage (A): Input the amperage value.
4. Enter Voltage (V): Input the voltage value.
5. Click “Calculate”: Once you’ve entered the required information, click the button to compute the result.
6. View Results: The tool will display the calculated power consumption in kilovolt-amps (kVA).

Example Calculation:

Let’s consider the following scenario:

• Phase: 3-phase
• Voltage Type: Line to Line
• Amperage: 50 A
• Voltage: 480 V

Using the appropriate formula for 3-phase power:

Power (kVA)=3×Amperage×Voltage1000Power (kVA)=10003​×Amperage×Voltage​

Power (kVA)=3×50×4801000Power (kVA)=10003​×50×480​

Power (kVA)≈41.57 kVAPower (kVA)≈41.57 kVA

Result: The power consumption is approximately 41.57 kVA.
