A Complete Power Factor & Harmonic Solution
ISO 9001 - 2008 Certified Company
Custom Detuned Harmonic Filter Panels
Engineer-led solutions to eliminate harmonic resonance and extend the life of your power factor capacitors.
Consult an Expert
PS Power Controls is a specialized Detuned Harmonic Filter Panel Manufacturer in Chennai. Our panels consist of high-quality capacitors connected in series with precisely matched reactors. This configuration ensures that the capacitor bank does not tune to the harmonic frequencies generated by your industrial loads, effectively preventing resonance-induced failures and ensuring a stable power factor of 0.99.
Key Merits & Benefits
Overload Prevention
Prevents capacitors from getting overloaded due to 5th, 7th, and higher-order harmonics.
No Current Amp
Ensures that switching current amplification does not happen, protecting your switchgear.
Equipment Safety
Prevents overheating of system transformers and rotating equipment (motors/generators).
Precise PF Control
Maintains a predefined target power factor (0.99+) while cleaning up the power network.
Technical Approach
We provide a thorough harmonic testing service before designing your panel:
| Phase 1: Testing | Onsite Power Quality & Harmonic Testing to identify distortion levels. |
|---|---|
| Phase 2: Calculation | Mathematical calculation of the exact reactor-capacitor combination required. |
| Phase 3: Fabrication | Custom manufacturing using branded components (EPCOS, L&T, etc.). |
| Phase 4: Support | Onsite commissioning and long-term maintenance support in Chennai. |
Frequently Asked Questions
What is harmonic resonance in an electrical system?
Resonance occurs when the inductive reactance of the system equals the capacitive reactance of the capacitor bank at a harmonic frequency. This can cause massive current spikes, leading to blown fuses and destroyed capacitors. Our detuned filters shift this resonance point to a safe frequency.
Why is a Detuned Harmonic Filter better than a standard APFC?
A standard APFC is designed only for reactive power. In a harmonic-rich environment, it acts as a sink for harmonics, which it isn't built to handle. A Detuned Filter is specifically designed to handle these harmonics safely while still providing the required reactive power.
