Formula to Convert kVAR to Farad
Use this formula to find the capacitance required for a specific reactive power:
• C = Capacitance in Farads
• Q = Reactive power in VAR (1 kVAR = 1000 VAR)
• f = Frequency in Hz
• V = Voltage in Volts
Step-by-Step Calculation Example
Example: Convert 10 kVAR to Farads at 400V and 50Hz.
Step 1: Convert kVAR to VAR
Q = 10 × 1000 = 10,000 VAR
Step 2: Use the formula
C = Q / (2 × π × f × V²)
Step 3: Insert values
C = 10000 / (2 × 3.1416 × 50 × 400²)
Step 4: Calculate denominator
400² = 160,000
2 × π × 50 ≈ 314.16
314.16 ×
160,000 = 50,265,600
Step 5: Final calculation
C = 10000 / 50,265,600
C ≈ 0.000199
