Active Harmonic Filter
Revolutionizing Power Quality with Intelligent Harmonic Compensation
In an era of digitized industries, variable frequency drives (VFDs), inverters, and other non-linear loads have become standard. However, they also introduce harmonic distortions that degrade power quality, reduce energy efficiency, and compromise equipment life.
At Greenventum, we deliver state-of-the-art Active Harmonic Filters (AHFs) — designed to intelligently detect, analyze, and neutralize harmonic currents in real-time, ensuring your electrical infrastructure performs at its cleanest and most efficient level.
What is an Active Harmonic Filter?
An Active Harmonic Filter is a power electronic device that continuously monitors the load current and injects equal but opposite harmonic currents into the system, thereby canceling out distortions caused by non-linear loads.
Unlike passive filters, AHFs dynamically adjust to varying load conditions and harmonic spectrums, offering superior precision, adaptability, and power quality enhancement.
