This tool will convert your kVA values to amps for three-phase circuits.
How to Use the KVA to Amps 3-Phase Calculator
This calculator converts KVA to Amps for a 3-phase AC circuit. To use the calculator, follow these steps:
- Enter the voltage (V) in volts.
- Enter the power factor (PF) which must be a value between 0 and 1.
- Enter the KVA value.
- Press the “Calculate” button to see the results in the table below.
How It Calculates the Results
The formula used to calculate the current (Amps) from the given KVA, voltage (V), and power factor (PF) is as follows:
Amps = (KVA * 1000) / (V * 1.732 * PF)
Where:
- KVA is the apparent power in kilovolt-amperes.
- V is the voltage in volts.
- 1.732 is the square root of 3, which is used in three-phase power calculations.
- PF is the power factor, a dimensionless number between 0 and 1.
Limitations of the Calculator
The calculator assumes that the system is balanced and that the voltage and power factor are correctly measured. It does not account for unbalanced systems or other power quality issues.
