Power Quality and Improvement - Power Quality and Improvement
Description
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 problems can cause unplanned, expensive outages and equipment failures. Main topics: Power Quality Standards and their effect on energy quality Voltage and frequency modulators and the resulting harmonics The effect of harmonics in low voltage networks Power Factor correction Quality with AC and DC and new energies The relationship between energy quality and earthing
