Q Sine Offers Power Quality Enhancement & Power Continuity Solutions
Active Harmonic filter

AHF is used to filter out harmonics in the power system. It mitigates harmonics by injecting active power with reverse phase to cancel that harmonic. We offer AHF from 30A to 1000A rating with 2 Level and 3 Level topology.
- Reduces the Harmonics in compliance with IEEE 519:2014
- Maintains Unity PF operation
- Ensures Load balancing
- Reduces overloading and overheating of Neutral conductor
- Help in avoiding the nuisance tripping of switchgear caused due to harmonics
- Compensates neutral current (with 3Ph4W option only)
- Lowers the energy Bill
