What is Feigin AHF

Feigin AHF is an advanced Active Harmonics Filter designed to eliminate electrical distortion, reduce Total Harmonic Distortion (THD), and stabilize voltage in real time. It safeguards sensitive equipment, enhances system efficiency, and ensures long-term operational reliability across dynamic power environments.

What is Feigin AHF

Feigin AHF is an advanced Active Harmonics Filter designed to eliminate electrical distortion, reduce Total Harmonic Distortion (THD), and stabilize voltage in real time. It safeguards sensitive equipment, enhances system efficiency, and ensures long-term operational reliability across dynamic power environments.

Harmonics are controlled by monitoring and outputting reverse current.

Different specifications are available and can be freely connected in parallel (30, 50, 75, 100, 150, 200A).

Comply with IEC, GB standards, with CNAS and CE certification.

The use of thyristors effectively avoids capacitor life issues, reducing downtime and maintenance costs.

Equipped with local monitoring system and can be connected to Scada and other systems.

Key Benefits of Feigin AHF

Improved Power Quality

Actively filters harmonics and maintains Total Harmonic Distortion (THD) within safe limits for stable, high-quality power delivery.

System Efficiency

Minimizes energy losses caused by harmonic distortion, improving the overall efficiency of power transmission and equipment performance

Equipment Longevity

Protects transformers, motors, and cables from harmonic-induced overheating and stress, extending the lifespan of critical infrastructure

Why Harmonics Matter

Harmonics silently damage your electrical infrastructure. Feigin AHF stops it at the source
