In the modern power systems, dynamic harmonic filter systems are necessary devices for reducing the negative effects of harmonic currents. Such currents can cause overheating, equipment damage, and energy loss. Sinotech Group's developed systems employ advanced technology that fluctuates in response to the load conditions thus providing active harmonic compensation. With the application of our filters, organizations can export their electric systems to international standards and improve the reliability and efficiency of the systems which is more economical for heavy users of power.
