POWER QUALITY & PENALTY ELIMINATION · WAPDA / NEPRA STANDARDS
Power Factor (PFI) & Penalty Calculator
Calculate the exact capacitor bank size (kVAR) needed to improve your factory power factor from 0.70 to 0.98, eliminate DISCO low-PF penalties, and free up transformer capacity.

📉 Power Factor Formula & Penalty Surcharge Mechanism:
Formula: Required kVAR = Active kW × [tan(arccos(PF₁)) - tan(arccos(PF₂))]
Under NEPRA regulations, when an industrial consumer's power factor drops below 0.90, DISCOs apply a penalty surcharge of up to 1.5% to 2% of the total monthly bill for every 0.01 drop. Installing a custom automatic PFI panel typically amortizes 100% of its cost in 3 to 5 months.
