Power Factor Capacitors — Frequently Asked Questions
What is the price of a power factor capacitor in Pakistan?
CNC power factor capacitors: 5 kVAR Rs.12,500; 10 kVAR Rs.22,000; 25 kVAR Rs.48,000; 50 kVAR Rs.85,000; 100 kVAR Rs.155,000. APFC controllers with staged capacitors Rs.95,000+.
How does WAPDA penalty for low power factor work?
Bills below 0.90 PF incur 2-12% surcharge. A Rs.500,000 monthly bill at 0.78 PF costs Rs.40,000/month extra. Installing a 50 kVAR correction cap (Rs.85,000) typically pays back in 2-3 months.
What size capacitor for my factory?
Formula: Required kVAR = kW × (tan φ₁ - tan φ₂). For 100 kW load at 0.78 PF corrected to 0.95: 100 × (0.802 - 0.329) = 47 kVAR — pick 50 kVAR standard size.
Do I need detuned harmonic reactors?
Yes if your facility has VFDs, UPS, or significant non-linear loads. Harmonics resonate with raw capacitor banks causing rapid failure. Detuned banks include series reactors to block resonance.
