Three-Phase MW to Amps Formula
I(A) = (P(MW) × 1000) / (√3 × V(kV) × PF)Where:
- I (A): Current in Amperes
- P (MW): Power in Megawatts
- V (kV): Line-to-Line voltage in Kilovolts
- PF: Power Factor (usually between 0.8 and 1.0)
- √3: Square root of 3 (approx. 1.732)
Frequently Asked Questions
How to convert MW to Amps?
To convert Megawatts (MW) to Amps, you need to know the voltage (kV) and the power factor. For a 3-phase system, the formula is: I (A) = (P (MW) × 1000) / (√3 × V (kV) × PF).
What is the current for 1 MW at 11kV?
For a 1 MW load at 11kV with a 0.8 power factor, the current is approximately 65.6 Amps in a 3-phase system.
Why do we divide by √3?
In 3-phase systems, the power calculation involves the line-to-line voltage. The factor √3 (approx. 1.732) accounts for the phase relationship between the three lines.
