Active Harmonic Filters (AHFs) are of great importance in today’s electrical systems since they work to correct the harmonic currents that are caused by nonlinear loads. These filters engage sophisticated methods to identify and eliminate harmonics, thus enabling the transmission of clean and stable power to the supplied equipment. This is critical in industries where there is the use of delicate electronic apparatus since harmonic distortion will cause malfunctions and increased costs of operations. Thanks to their knowledge of power quality issues, Sinotech Group develops the latest AHFs that meet the various demands of their overseas clients and conform to the industry requirements while improving systems performance.
