Energy Efficiency & Power Quality
Automatic Power Factor Improvement (PFI) Panels
Invest in Safety, Optimal Efficiency & Reduced Utility Penalties Across Bangladesh
Welcome to Moon Star Power & Technology! Building on our long-standing expertise in substation engineering and industrial electrical infrastructure, we manufacture state-of-the-art Automatic Power Factor Improvement (PFI) Panels. Designed to eliminate reactive power wastage, prevent utility low power factor penalties (imposed by BPDB/REB for PF < 0.90), reduce cable overheating, and stabilize plant voltage, our PFI panels are essential for modern commercial and industrial facilities.
Key Performance Highlights
Zero Utility Surcharge
Maintains target power factor above 0.98 to eliminate electrical grid penalties.
Energy Savings
Reduces kVAR demand, lowering heat losses in plant transformers and cables.
Automatic Switching
Microprocessor APFC relays dynamically regulate capacitor bank steps.
Harmonic Protection
Heavy-duty capacitors engineered to handle non-linear industrial loads safely.
Understanding Power Factor & Sizing Calculation
Electrical loads like induction motors, transformers, and HVAC compressors consume active power ($kW$) for real work and reactive power ($kVAR$) for magnetic fields. Excess reactive power degrades overall system efficiency. To determine the necessary PFI capacity, our engineering team utilizes exact load sizing calculations:
Required kVAR = Total kW × [ tan(arccos(PF_old)) - tan(arccos(PF_new)) ]
For instance, elevating a 500 kW industrial facility from a low 0.75 PF up to 0.98 target PF requires precise multi-step capacitor sizing to avoid both under-correction and over-correction hazards.
World-Class Component Sourcing
At Moon Star Power & Technology, we integrate tier-1 global hardware to prevent capacitor rupture, fire risks, and contactor welding:
Heavy-Duty Capacitors
EPCOS (TDK Japan Tech) & ABB (India) gas-filled/dry-type self-healing capacitors with built-in overpressure disconnector protection.
Smart APFC Relays
mikro (Malaysia) automatic digital power factor controllers providing precise RMS measurements, THD monitoring, and automatic step rotation.
Switching Contactors
Hyundai (Korea) & Donga (Korea) specialized duty contactors fitted with damping resistors to suppress high inrush currents.
Moon Star PFI Panel vs. Conventional Local Panels
| Evaluation Feature | Moon Star Power PFI Panel | Substandard Local Panels |
|---|---|---|
| Energy Savings | Guaranteed 0.98+ PF (Zero Penalty) | Inaccurate step switching & recurring penalties |
| Capacitor Quality | EPCOS / ABB Dry-Type Duty | Low-grade oil capacitors prone to explosion |
| Inrush Protection | Damping resistor contactors integrated | Standard contactors prone to contact welding |
| Equipment Life | Extends transformer & cable lifespan | Causes excessive overheating and harmonics |
