How to Use This Calculator
- Enter the voltage and current values.
- Select the power factor.
- Click ‘Calculate’.
Formula & Methodology
The formula for three phase power is: P = √3 * V * I * PF, where P is power, V is voltage, I is current, and PF is power factor.
Real-World Examples
| Voltage (V) | Current (A) | Power Factor | Power (kW) |
|---|---|---|---|
| 400 | 50 | 0.8 | 80 |
| 690 | 100 | 0.9 | 618.3 |
| 230 | 75 | 0.7 | 110.2 |
Data & Statistics
| Power (kW) | Energy (kWh) | Cost ($) |
|---|---|---|
| 100 | 8760 | 8760 * $0.10 = $876 |
| 500 | 43800 | 43800 * $0.10 = $4380 |
Expert Tips
- Always use the correct voltage and current values for your system.
- Power factor can vary, so use the most accurate value available.
- Regularly monitor and maintain your three phase system to ensure optimal performance.
