Wall-mounted Active Harmonic Filter

GEYA Wall-mounted Active Harmonic Filter (AHF) is a cutting-edge power electronics device designed for dynamic harmonic suppression, reactive power compensation, and three-phase imbalance regulation. It utilizes sampling current transformers to isolate and extract harmonic currents and reactive currents from the load current. The system actively generates and controls the output current in terms of magnitude, frequency, and phase, enabling rapid response to counteract corresponding load currents. This ensures dynamic tracking compensation, effectively neutralizing distortions and optimizing power quality in real time.

Where is Active Harmonic Filter (AHF) Used?

GEYA’s AHF is ideal for industries and facilities with sensitive equipment:

Manufacturing: Protect CNC machines, welding systems, and VFD-driven motors.

Data Centers: Ensure clean power for servers and UPS systems.

Healthcare: Stabilize voltage for MRI machines and lab equipment.

Renewable Energy: Mitigate harmonics in solar/wind inverters.
