tool.power-factor-correction Calculator
Calculates the capacitor bank size (in kVAr) needed to correct power factor from a measured value to a target, reducing apparent power drawn from the utility. Power factor below 0.9 incurs utility penalties for commercial customers — correction capacitors typically pay back in 1–3 years.
Inputs
Real Power Kw
Rate of energy transfer (W). P = V×I (electrical). P = F×v (mechanical). 1 horsepower ≈ 746 W.
Current Pf
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Target Pf
A multiplier applied in the calculation.
Voltage Line V
Electric potential difference (V). Drives current through a circuit. Household: 120 V (US) or 230 V (EU/UK).
Results
capacitor bank needed (kVAR)
Voltage in kilovolts (kV). 1 kV = 1,000 V. Used for high-voltage transmission lines and industrial equipment.
capacitance (µF)
Sample size or count used in the calculation.
before PFC: reactive power
Reference formula or conversion factor shown for context.
after PFC: reactive power
Reference formula or conversion factor shown for context.
kVA reduction
Voltage in kilovolts (kV). 1 kV = 1,000 V. Used for high-voltage transmission lines and industrial equipment.
