POWER QUALITY & APFC CORRECTION
Power Factor (APFC) & Capacitor Bank Calculator.
Determine the exact reactive power compensation (kVAr) required to raise your plant operating power factor, eliminate mandatory KSEB low-PF surcharges, and release transformer capacity.
Step 1: Electrical System Health
Power Factor & Operating Load
Operating Active Load (kW)
kW
Current Operating Power Factor (PF₁)0.78 (Lag)
Typical uncompensated induction motor load is 0.70 – 0.82Target Corrected Power Factor (PF₂)0.98 (Target)
Recommended 0.98 – 0.99 to capture KSEB incentives without over-compensationOperating below 0.90 PF incurs mandatory KSEB low power factor surcharge penalties every billing cycle!
