## Three-Phase Power Calculations
Three-phase systems are the standard for industrial and commercial power distribution.
### Formulas (Balanced Load)
**Apparent Power = sqrt(3) x V_line x I_line**
**Real Power = Apparent x Power Factor**
**Reactive Power = sqrt(Apparent^2 - Real^2)**
**Phase Voltage = Line Voltage / sqrt(3)**
The sqrt(3) factor (approximately 1.732) arises from the 120-degree phase separation between the three phases.

हल किया गया उदाहरण
480 V three-phase, 20 A line current, 0.85 power factor.
- Apparent: sqrt(3) x 480 x 20 = 16,627 VA = 16.63 kVA
- Real: 16,627 x 0.85 = 14,133 W = 14.13 kW
- Reactive: sqrt(16627^2 - 14133^2) = 8,744 VAR = 8.74 kVAR
- Phase voltage: 480 / 1.732 = 277.1 V
