What is an Active Harmonic Filter

Think of an Active Harmonic Filter (AHF) as noise-canceling headphones for your electrical system.

In modern industrial and commercial facilities, non-linear loads—such as variable frequency drives (VFDs), LED lighting, and IT equipment—introduce "harmonic distortion" into the grid. This is essentially electrical noise that overheats cables, trips circuit breakers, and damages sensitive machinery.

An AHF solves this by actively monitoring the power line in real-time. The instant it detects harmonic current, it generates and injects an equal and opposite compensating current. This process completely neutralizes the distortion, restoring a clean, stable sine wave.
