Power Qaulity Issue Power quality issues can increase your utility and operating costs. In a 3-phase power system, any disturbance on one parameter (magnitude, frequency, waveform, or symmetry) is classified as a power quality problem. Even minor disruptive voltage fluctuations can cause major issues from equipment malfunctions, to flickering lights, to complete power shutdowns. Power quality prob...

What Cause Power Quality Problems? Modern power electronics devices applications can improve our work more efficiency and make life easier, but at the same time they can pollute the power networks. Rectifiers play a large part in many applications that are growing faster than power system construction. Voltage and current harmonics, reactive power fluctuation, three phase unbalance, and other issu...

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...
