Active Harmonic Filters
We are Authorised Solution Partner for L&T make AHF and can give end to end solution like Harmonics Study, Anylisys and suitable solution with installation and commissioning of Harmonic Filters.
Description:
- With active harmonic filters, reduce your THD levels to within IEEE/CEA limits. These filters are IGBT-based power converters. This filter injects negative of the harmonic current resulting in practically no harmonic distortion.
- Phase balancing and power factor correction is also achieved.
Features:
- 30-600 A Active filter in 3 phase 3 wire/4wire
- Stand-alone & modular units
- Response time less than 1 ms
- Easy diagnosis of fault conditions with alarms
- Easy configuration & parameter monitoring with LCD touch screen HMI
Reactors – Harmonic Filtering
Description:
- Detuned harmonic filters are the series combination of a reactor and power capacitor. This filter offers higher impedance for high frequency harmonics. This prevents harmonic resonance and amplification.
7% reactor mitigates 5th harmonic & above:
- For industries with drives, converters & other power electronic devices
14% reactor mitigates 3rd harmonic & above:
- For IT industries
- For industries with high single-phase non-linear load
Features:
- Available as 7% (189 Hz) & 14% (133 Hz) detuned filters
- Copper & Aluminium wound reactors
- Very low operating losses - 3 to 5 W / kVAr
- High linearity - 1.8 times the rated current
- Low noise
- Auto-thermal cut-off
