Industrial Power Factor Correction & APFC Sizing
A poor power factor in an industrial facility leads to severe financial penalties from electricity DISCOMs, increased line losses, transformer overheating, and wasted electrical distribution capacity. At iPower Switchgear, we provide specialized Power Factor Correction (PFC) Studies, Automatic Power Factor Correction (APFC) panel sizing, and capacitor bank design for manufacturing plants, commercial complexes, and process industries across Ahmedabad, Gujarat, and pan-India.
Electricity utilities in Gujarat (UGVCL, DGVCL, MGVCL, PGVCL, Torrent Power) impose heavy low power factor penalties while offering power factor rebates for facilities maintaining a power factor near unity (0.99–1.00). Our engineers analyze load profiles, reactive power demand (kVAr), and harmonic spectrums to engineer custom APFC solutions that maximize tariff incentives while avoiding destructive harmonic resonance.
Core Engineering Benefits of Power Factor Optimization
- Elimination of DISCOM Low PF Penalties: Raises plant power factor from typical uncompensated levels (0.75–0.85) to near-unity (0.99+), qualifying for utility power factor rebates.
- Transformer & Cable Capacity Release: Reduces total kVA demand (kVA = √(kW² + kVAR²)), freeing up valuable transformer capacity for plant expansion without costly equipment upgrades.
- Reduction of I²R Cable Losses: Lowering line current reduces thermal energy losses in distribution feeders, lowering electricity bill consumption (kWh).
- Detuned Reactor Protection Against Harmonic Resonance: Integrates 7% or 14% detuned reactors (de-tuned capacitor banks) to prevent capacitors from resonating with VFD/rectifier harmonics.

KVAR Demand Analysis & Capacitor Sizing
We analyze your facility's recorded demand data and power system load flow model to calculate the exact reactive power (kVAR) deficit at each bus. We then precisely size fixed capacitor banks at motor terminals and automatic power factor correction (APFC) panels at the main supply point to achieve your target power factor efficiently.
Optimal Placement Strategy
The location where you install reactive compensation makes a significant difference to results. We identify whether fixed compensation at individual motor terminals, group compensation at MCC buses, or centralized APFC at the main switchboard gives the maximum reduction in cable and transformer losses for your specific network topology.
Harmonic Resonance Safety Check
Installing capacitors in a network with significant harmonic sources can create dangerous resonance. Before finalizing the design, we run a frequency scan to verify that the proposed capacitor configuration does not create a parallel resonance at any harmonic order present in your system. If a risk is found, we specify detuning reactors to make the installation safe.
Utility Penalty Savings & ROI Calculation
We calculate your current and projected utility power factor penalty charges based on your actual electricity tariff (DISCOM rate schedule for Gujarat or your state). The study shows the exact annual savings in penalty charges, transformer loading reduction, and cable loss savings — with a clear payback period for the capital investment in correction equipment.
