kV to MW Calculator
Calculate Megawatts (MW) from Kilovolts (kV) and Amperes (A) for 3-Phase AC systems.
kV
A
Calculated Power (MW)
0MW
Formula: P(MW) = (√3 × kV × A × PF) / 1000Note: kV cannot be converted to MW directly. You must know the current (Amps) and Power Factor to calculate the actual power.
Common kV to MW Conversions (3-Phase)
| Voltage (kV) | Current (A) | PF | Power (MW) |
|---|---|---|---|
| 11 kV | 100 A | 0.8 | 1.524 MW |
| 11 kV | 200 A | 0.8 | 3.048 MW |
| 33 kV | 100 A | 0.8 | 4.572 MW |
| 33 kV | 200 A | 0.8 | 9.145 MW |
| 66 kV | 100 A | 0.8 | 9.145 MW |
| 132 kV | 100 A | 0.8 | 18.290 MW |
Three-Phase kV to MW Formula
P(MW) = √3 × V(kV) × I(A) × PF / 1000Where:
- P (MW): Real power in Megawatts
- V (kV): Line-to-Line voltage in Kilovolts
- I (A): Current in Amperes
- PF: Power Factor (usually between 0.8 and 1.0)
- √3: Square root of 3 (approx. 1.732) for 3-phase systems
Frequently Asked Questions
Can you convert kV to MW directly?
No, kV (kilovolts) is a unit of voltage, while MW (megawatts) is a unit of power. To calculate power, you need to know the voltage, current (Amps), and the power factor of the system.
How many MW is a 33kV line?
A 33kV line doesn't have a fixed MW value. It depends on the current it carries. For example, a 33kV line carrying 100A with a 0.8 power factor would provide approx 4.57 MW of power.
What is the formula for kV to MW in 3-phase systems?
The formula is: P (MW) = (√3 × V (kV) × I (A) × PF) / 1000. Where √3 is approx 1.732.
