Industries today, rely heavily on electronic equipment, so maintaining a high level of power quality is essential. However, the proliferation of non-linear loads in electrical systems, such as variable frequency drives and power converters, has increased harmonic distortion, posing challenges for power quality management. To address this issue, integrating active harmonic filters (AHFs) into existing electrical systems has become a popular solution. But how exactly does one integrate these devices, and what considerations are crucial during installation? Let's delve into the process. Firstly, before integrating an active harmonic filter, it's important to conduct a thorough assessment of the existing electrical system. This involves analysing the harmonic spectrum, identifying the main sources of harmonic distortion, and determining the appropriate location for installing the AHF. Typically, AHFs are installed at the point of common coupling (PCC), where multiple loads connect
