Dynamic filters enable operating in real time and are therefore critical when there are unpredictable electrical loads in the system. OTOH Static filters are passive filters and act as permanent fixtures in regulated and stable environments. The understanding of passive and active filters helps a great deal to power and decision engineers in the energy sector so that they can select a fitting solution for every case. Sinotech Group practices both technologies and integrates them in a way that the company improves the power quality and efficiency for various applications.
