Nexus Power active harmonic filter or the power filter (AHF) is connected in parallel with non-linear loads and uses one set of current transformers (CT) to detect the load current. It calculates each order harmonic current by FFT algorithms in its DSP microchips, and then generates a compensating current with the same amplitude but opposite phase angles to the detected harmonic current, which cancels out the original load harmonics.
The Nexus Power active harmonic filters provide solution for real-time cancellation of harmonic distortions created by non-linear loads to ensure compliance with IEEE 519, G5/4 and other power quality standards and recommendations. Nexus Power active harmonic filters are a versatile solution, easily tailored to deliver power factor improvement, voltage variation control, flicker mitigation and load balancing functionality.
Nexus Power AHF’s are built on 3-level topology and are designed for industrial and commercial buildings with voltage level up to 690V in both 3W and 4W applications. Nexus Power AHF’s are customized for demanding applications and are available from 480V up to 1000V.
Nexus Power Active harmonic filtering technology can be applied to wide range of industrial and commercial environments where good power quality is essential. Nexus AHF have been used for the processes that use Variable Speed Drives (VSD), LED Lights, fast fluctuating loads such as welding machines, Uninterrupted Power Supply (UPS) systems and DC load, SMPS, single phase loads such as lighting and computers as well as electric arc furnaces and rolling mills.
Nexus SVGC, the most economic solutions for reactive power compensation with better effect than traditional capacitor bank. Nexus SVGC integrate TSC and SVG, modular design, with dynamic compensation functions of reactive power compensation, harmonics compensation, voltage fluctuation, load unbalance.
