This tool will help you convert kilowatts to amperes in a 3-phase electrical system easily.
How to Use the Calculator
To calculate the current (amps) in a 3-phase system based on the power (in kW), voltage, power factor, and efficiency, follow these steps:
- Enter the power in kilowatts (kW).
- Enter the voltage in volts (V).
- Enter the power factor. This is a value between 0 and 1.
- Enter the efficiency in percentage (%). Ensure this value is between 0 and 100.
- Click on the “Calculate” button to see the results.
How It Works
The formula used to calculate the current (amps) in a 3-phase system is:
Amps (A) = (Power (kW) * 1000) / (√3 * Voltage (V) * Power Factor (PF) * Efficiency)
Where:
- Power is the active power in kilowatts (kW).
- Voltage is the line-to-line voltage in volts (V).
- Power Factor is the ratio of real power flowing to the load to the apparent power in the circuit.
- Efficiency is the ratio of the useful power output to the total power input, expressed as a percentage.
Limitations
While this calculator provides an estimation, several factors can affect actual current draw, including:
- Temperature changes altering resistance values.
- Harmonics present in the power system.
- Accuracy of provided input values.
Always consult with a certified electrician or engineer for precise measurements and system design.
