Active Harmonic Filter (APF)

An Active Harmonic Filter (APF) is a modern electronic device used to reduce harmonic distortion in electrical power systems. By dynamically monitoring and analyzing the current waveform, APFs generate corrective currents that cancel out harmonics, thereby improving power quality and reducing energy losses. These advanced filters are essential for mitigating harmonic distortions caused by non-linear loads such as variable frequency drives, computers, and LED lighting. With their real-time monitoring and active compensation capabilities, Active Harmonic Filters play a crucial role in enhancing system efficiency, reducing equipment wear, and complying with regulatory standards.
