Power Factor Improvement (PFI) & Control Panels

Automated Capacitor Banks & Custom Industrial Electrical Control Panels

Power factor correction is the switching of capacitors in parallel with inductive loads in the electrical network. Our automatically controlled capacitor banks—the VOLTCORE Power Factor Improvement (PFI) Plant—relieve generators, transformers, and distribution cables of reactive power, eliminating utility surcharge penalties, reducing voltage drop, and cutting operational energy costs.

Engineering Standards & Utility Compliance:

IEC 60831-1/2 (Power Capacitors) IEC 60947 (Switchgear & Control) DPDC / DESCO / BREB / BPDB Compliant BSTI / BDS Certified DIN / IEC IP40 / IP54 Protection

Reactive Power Compensation & Energy Optimization

Power Factor Improvement (PFI) Plant

Inductive equipment such as motors and transformers demand reactive power (kVAR), causing transmission line losses, overheating, voltage drops, and heavy electricity surcharge penalties from utilities. VOLTCORE PFI Plants continuously measure reactive power requirements and automatically step capacitor banks in or out to maintain an optimal power factor between 0.95 and 0.99 lagging.

Factory-assembled automatic capacitor bank cubicles equipped with intelligent microprocessor power factor controllers, heavy-duty capacitor switching contactors, and high-reliability discharge resistors.

Key Features of VOLTCORE PFI Plants:

1) Modular Design: Multi-step modular layout (6, 8, 12, or 14 steps) engineered to match fluctuating load profiles in textile, commercial, and industrial facilities.
2) Compact Arrangement: Space-saving floor-standing cubicle layout with optimized thermal ventilation louvers, saving valuable substation space.
3) Low Losses Capacitors: Heavy-duty self-healing dry type or oil-impregnated cylindrical power capacitors with internal overpressure tear-off safety disconnectors.
4) High Reliability: Intelligent micro-controller switching relays with digital LCD display, circular step switching, and overvoltage / harmonic protection.
5) Factory Wired & Tested: 100% pre-wired and factory tested with capacitor-duty contactors, HRC backup fuses, and fast discharge resistors for immediate commissioning.
6) Fully Extendible: Modular busbar architecture permits simple on-site addition of extra capacitor steps as facility electrical demand increases.
