This tool will help you calculate the total power usage of a three-phase electrical system.

## 3-Phase Power Calculator

This 3-phase power calculator is designed to help you calculate the power in a 3-phase electic system.

### How to Use

- Enter the Voltage (V) of your system. This should be a number greater than 0.
- Enter the Current (A) in amperes. This should be a number greater than 0.
- Enter Power Factor, a dimensionless number between 0 and 1.
- Click “Calculate” to see the result.

### How it Calculates

The calculator uses the formula:

**Power (W) = √3 * Voltage (V) * Current (A) * Power Factor**

### Limitations

- This calculator assumes a balanced system where all phases have equal current and voltage.
- The Power Factor must be a value between 0 and 1. Values outside of this range are not valid and will produce an error.
- All inputs must be positive non-zero numbers for the calculator to function correctly.
