Active Harmonic Filter (AHF)
Active harmonic filters (AHF) are the ultimate answer to power quality problems caused by waveform distortions, low power factor, voltage variations, voltage fluctuations and load unbalance for a wide range of segments and applications. They are a high performance, compact, flexible, modular and cost-effective type of active power filters (APF) that provide an instantaneous and effective response to power quality problems in low or high voltage electric power systems. They enable longer equipment lifetime, higher process reliability, improved power system capacity and stability, and reduced energy losses, complying with most demanding power quality standards and grid codes.
Overview
A2 Series
AHF Module Rate 400 V 50/60 Hz 100A
AHFs eliminate waveform distortions from the loads like harmonics, interharmonics and notching, and harmonic voltages caused by harmonic currents, by injecting in real-time the distorted current of same magnitude but opposite in phase in the electric power system. In addition, AHFs can take care of several other power quality problems by combining different functions in a single device:
• Elimination of harmonics and interharmonics.
• Power factor correction (lagging and leading).
• Reduction of voltage variations (sags & swells).
• Mitigation of voltage fluctuations (flicker).
• Load balancing in three-phase systems.
• Controlled and selectable harmonic generation.
