ELECTRICAL / REACTIVE COMPENSATION
Power Factor Correction Calculator
Estimate capacitive kVAR and apparent-power reduction required to move a positive real-power load from one power factor to a higher target.

Calculation path
Real power and the tangent of each phase angle produce reactive demand before and after correction; the difference is capacitor kVAR.
Calculation path
Capacitor kVAR = kW x (tan(arccos existing PF) - tan(arccos target PF)).
