Formula for Amps to MVA
For accurate conversion, use the correct formula:
Step-by-Step Example (Three-Phase)
Convert 400 amps at 11,000 volts to MVA.
Step 1: Write the formula
MVA = (√3 × V × I) ÷ 1,000,000
Step 2: Insert values
MVA = (1.732 × 11,000 × 400) ÷ 1,000,000
Step 3: Multiply values
MVA = (1.732 × 4,400,000) ÷ 1,000,000
Step 4: Final result
MVA = 7.62 MVA
Key Notes
- Use √3 only for three-phase systems.
- Divide by 1,000,000 to convert VA to MVA.
- This calculation applies to apparent power.
