Active Harmonic Filter (AHF / APF)
Active Harmonic Filter (AHF / APF) – Highlights
- Filters 2nd–50th order harmonics (up to 98%)
- Auto reactive power compensation (PF -0.99 to +0.99)
- Corrects load imbalance and reduces neutral current
- ≥97% efficient, low thermal loss
- Modular design: 30A–750A (scalable)
- Works in harsh environments, DG compatible
- Auto polarity correction & grid/load side detection
- Auto shutdown on overvoltage, current, temp
- Fault log with timestamp
- Improves power quality, equipment life, reduces penalties
- Complies with IEC, IS standards
Passive Harmonic Filter (PHF) – Highlights
- Reduces fixed harmonics (5th, 7th, 11th, 13th)
- Improves power factor & lowers THDi <15%
- Tuned (e.g., 250Hz) or Detuned (189/210Hz) options
- Rated for 400–415V, 50Hz
- Uses heavy-duty capacitors & air/iron-core reactors
- Available with IP42/IP54 enclosure, natural/forced cooling
- Thermal, overvoltage, inrush, and fuse protection
- Contactor-based switching with optional APFC relay
- Ideal for fixed loads (HVAC, pumps, drives)
- Low-cost, low-maintenance solution
- Enhances equipment life, reduces heat & distortion
- Not for dynamic loads
- Requires correct tuning to avoid amplification
