Engineering calculator
Capacitor bank sizing
Reactive compensation needed to correct to a target power factor.
Inputs
Results
- Required compensation
- 236.8kVAr
- kVA reduction

Qc = P × (tan φ1 − tan φ2)
Assumptions
- Constant active power
Limitations
- Resonance with network harmonics must be checked — detuned reactors may be required
- Switching transients and step sizing not addressed
