Is your facility struggling with unbalanced load currents?
In many industrial and commercial setups, loads like motors, lighting, and variable machinery draw uneven currents across the R, Y, and B phases. Traditional APFC systems apply uniform correction, which often leads to over-compensation in one phase and under-compensation in another. PS Power Controls' Single Phase Correction Technology is specifically designed to solve this by maintaining the Power Factor (PF) across each phase independently.
Star vs. Delta Connections in APFC
The configuration of your capacitor bank significantly impacts how it handles imbalances. At PS Power Controls, we utilize the Star (Wye) Connection for superior granular control.
Technology Comparison
| Feature | Star Connection (PS Standard) | Delta Connection (Conventional) |
|---|---|---|
| Configuration | Phase to Neutral (Y-shape) | Phase to Phase (Triangular) |
| Voltage Rating | 230V (Phase Voltage) | 400V (Line Voltage) |
| Correction Method | Individual Phase Correction | Uniform 3-Phase Correction |
| Unbalanced Loads | Ideal - Handles R,Y,B independently | Inefficient - Risks overvoltage |
| Harmonic Safety | Better handling of neutral currents | Higher risk of resonance |
Our Methodology: Precision Compensation
Our APFC panels employ a step-by-step methodology to ensure your network achieves a target PF of 0.98-0.99 even under heavy imbalance:
- Monitoring: Intelligent microprocessor relays use CTs on ALL THREE phases to measure real-time reactive demand independently.
- Analysis: The controller detects if one phase (e.g., R phase) has higher inductive load than the others.
- Switching: Contactors connect single-phase (230V) capacitors to the specific phase requiring kVAR injection.
- Protection: Built-in zero-crossing switching prevents transients, while overload relays protect against surges.
Commercial Benefits & Cost Savings
Eliminate Penalties
TNEB imposes heavy surcharges for PF < 0.90. Our star-connected panels ensure you consistently stay above 0.98.
Fast ROI
With electricity bill reductions of 10-30%, most clients achieve full payback within 12-18 months.
Lower Maintenance
Frequently Asked Questions
Why use 230V capacitors instead of 400V?
In a Star connection, the voltage across each capacitor is the phase-to-neutral voltage (230V). This allows for safer operation and allows the controller to switch banks for individual phases, which is impossible with 400V Delta-connected capacitors.
Is this suitable for my existing factory LT panel?
Yes! Our Single Phase Correction APFC panels are designed for plug-and-play integration. Installation typically requires less than 4 hours of downtime.
How does this handle TNEB demand charges?
TNEB charges based on kVA (Apparent Power). By correcting the power factor per phase to near unity, you significantly reduce your kVA demand, directly lowering your fixed monthly charges.
