SASTI-PQ6MU-AHF Active Harmonic Filter is a comprehensive solution addressing power quality issues such as harmonics, reactive power, and three-phase load imbalance in power grids.
- Parallel Connection: Connects parallelly to the power grid.
- Real-Time Detection: Identifies harmonic waves and generates reverse-phase compensation currents through a converter to dynamically filter these harmonics.
- Versatile Operation: Functions effectively with various load types and grid structures without causing harmonic oscillation (resonance).
- Dynamic Reactive Compensation: Enhances power factor by dynamically compensating reactive power and controlling capacitor switching.
- Load Unbalance Control: Manages three-phase load current imbalances, offering a comprehensive approach to power quality management.
Modular Design
The SASTI-PQ6MU Active Harmonic Filter boasts an advanced modular design. It usually comprises one or several AHF modules and an optional touch LCD Human Machine Interface. Each AHF module functions as an independent harmonic filtering system, enabling users to easily adjust the system's rating by adding or removing AHF modules.

AHF in Industrial Sector
Active Harmonic Filters are essential for improving power quality in industrial environments. They effectively mitigate harmonics, enhance power factor, and balance loads, ensuring efficient and reliable operation of electrical systems.
AHF in Commercial Sector
Active Harmonic Filters In commercial complex automation systems, numerous automation equipment require high-quality power supply. However, their nonlinear load characteristics often introduce harmonic distortions into the low-voltage power supply system. This pollution can disrupt the distribution system and impact surrounding communication networks.
AHF in Utilities and Power Generation
AHF play a critical role in utilities and power generation by ensuring high-quality power supply and mitigating harmonic distortions. They are essential for maintaining stable operations in power plants and renewable energy installations, where harmonic disturbances can affect equipment performance and reliability. AHFs help in complying with stringent grid codes and standards, ensuring transmission while safeguarding sensitive electrical components from damage due to harmonics.
