Active Harmonic Filters can be regarded as the necessary evils in the growing switch to today’s renewable energy systems as these devices solve the issue of harmonic distortion. How much distance there is available when it comes to wind energy or even solar energy has moved up a notch and thus comes a prerequisite of sharpening power quality measures. Sinotech Group is known to develop and produce advanced Active Harmonic Filters that reduce harmonic waves, and more importantly, maximize the performance of energy systems. Our filters are built to comply with international standards in order to be used reliably and with optimal performance in a range of applications, including but not limited to wind farms and assorted bulk and home solar power systems.
