Active Harmonic Filters

Description 

Active Harmonic Filters (AHF) device can eliminates multiple and higher harmonics without causing resonance, improve power quality and reduce power loss. AHF device prolongs service life of electrical equipment and improves the operation efficiency and output of equipment.

AHF device can be used with existing Power Distribution and PV Systems.

 

Advantages  

- Harmonics Compensation Capability Compensates 2nd to 50th harmonic order or simultaneous compensation of all

  50 harmonic orders.

- Compensates both inductive and capacitive loads Corrects lagging and leading power factor.

- Algorithm Intelligence technology integrates both FFT and Dynamic Compensation Modes, customised to client’s

  requirements.

- Reducing Harmonic Distortion Rate and extending the life of transformer.

- Modular design for easy operation, maintenance and replacement.
