- Power Factor Correction: Sizing Capacitor kVAR and Cutting Demand Charges
kVAR = kW × (tan θ₁ − tan θ₂). Correcting 80 kW from 0.80 to 0.95 needs 33.7 kVAR, cuts current 15.8% and cuts I²R losses 29.1% - and getting to unity costs as much again.
- kVA vs kW: Power Factor, Apparent Power, and Why It Matters
kW = kVA × power factor. At PF 0.8 the power triangle is a 3-4-5: 100 kVA is 80 kW and 60 kVAR - and the conductor is sized for the hypotenuse, not the base.
