Detuned Automatic Power Factor Correction Panel

PS Power Controls is a premier Detuned APFC Panel Manufacturer in Chennai. In modern industrial setups featuring Variable Frequency Drives (VFDs), UPS systems, and large-scale LED lighting, harmonics are a major concern. A standard APFC panel can amplify these harmonics through resonance, leading to capacitor failure and system trips. Our Detuned APFC Panels are engineered with high-quality series reactors (7% or 14%) to safely mitigate harmonics and maintain a perfect power factor.

Technical Advantages

Harmonic Blocking

Blocks harmonic currents from entering the capacitors, preventing overheating and premature failure.

THD Reduction

Significantly reduces Total Harmonic Distortion (THD) levels, improving overall power quality.

Extractable Modules

Designed with steel cabinets in extractable module design for easy maintenance and expansion.

CPRI Tested

Built to strict industry standards and CPRI tested for maximum safety and durability.

Our panels are widely acknowledged for their sturdy construction, trouble-free operations, low maintenance, and high reliability.

Frequently Asked Questions

When should I choose a 7% reactor in my APFC panel?
A 7% reactor is the most common choice for industrial loads in Chennai. It detunes the system to 189Hz, which effectively blocks the 5th harmonic (250Hz) and above, which are typically the most destructive in VFD-heavy environments.
Can a detuned panel help with TNEB penalties?
Yes, absolutely. By maintaining a high power factor while safely handling harmonics, you ensure that your facility meets TNEB's strict PF requirements (above 0.95) without the risk of equipment downtime caused by standard capacitor failure.
What capacitors are used in Detuned APFC Panels?
We use specially rated heavy-duty capacitors (typically 480V or 525V rated for a 415V system) to handle the voltage rise across the detuned reactor. Branded components like EPCOS and L&T are our standard.
