How to Convert kvar to Microfarad
Converting kVAR to microfarads is common when sizing capacitors for power factor correction. The formula relates reactive power to the capacitive reactance of the component.
Formula:
Where:
- C = Capacitance in microfarads (µF)
- kVAR = Reactive power
- f = Frequency in Hz
- V = Voltage in volts
Step-by-Step Example
Example: Convert 10 kVAR to microfarads at 400V and 50Hz
Step 1: Write the formula
C = (kVAR × 109) / (2 × π × f × V²)
Step 2: Substitute values
C = (10 × 109) / (2 × 3.1416 × 50 × 400²)
Step 3: Calculate voltage square
400² = 160,000
Step 4: Multiply constants
2 × 3.1416 × 50 = 314.16
Step 5: Final calculation
C = (10,000,000,000) / (314.16 × 160,000)
Step 6: Solve
C ≈ 199 µF
Result: 10 kVAR ≈ 199 microfarads at 400V, 50Hz
