ZDDQ Active Harmonic Filter Active harmonic filter is connected in parallel with non-linear loads, and uses one set of 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 harmo...

ZDDQ-SVG Static Var Generator is an electronic reactive power compensation system, for both capacitive and inductive power. It has the same operating principle as an active filter; the SVG injects a current in the opposite direction to counteract the installation's non-useful power (inductive and capacitive), thus ensuring that the target cosϕ is achieved. ZDDQ SVG instantly compensates and adjust...
