Abstract: Utility power system harmonic problems can often be solved using a comprehensive approach including site surveys, harmonic measurements, and computer simulations. This case study presents the results for a commercial facility harmonic evaluation. The simulations were completed using the PSCAD program. The analysis evaluates the effects of transformer connections to determine the har...
Power quality metering for industrial efficiency In today's competitive industrial landscape, ensuring an uninterrupted, stable, and efficient power supply is essential. Power quality issues such as voltage fluctuations, harmonic distortion, and poor power factor can lead to significant operational downtime, costly equipment repairs, and reduced energy efficiency. Power quality metering is a criti...
Harmonics & VFDs: Causes, Solutions, and Key Insights How VFDs Cause Harmonic Issues Variable Frequency Drives (VFDs) are commonly used to control motor speed and optimize energy consumption in industrial systems. However, VFDs work as nonlinear loads. This means they draw currents that are not smooth, even if the supply voltage is a perfect sine wave. This happens because VFDs change AC power...
Power Quality Challenges: An Invisible Barrier to Economic Growth Electricity access has made significant strides across the globe, and more people than ever are connecting to the power grid. However, even in regions where access is available, many face a more insidious issue: poor power quality. This issue, which is often less visible than frequent power outages, presents a major challenge...
Poor power quality — characterized by fluctuations and/or persistently low or high voltages — has far-reaching consequences and should receive much more attention. Like lack of access, poor power quality holds back economic growth. But it is much harder to track and its prevalence is unknown because systems to measure it are not in place. We installed sensors across Nigeria to assess p...
Enhancing Power Quality in UPS Systems Uninterruptible Power Supply (UPS) systems are essential for maintaining continuous operations in environments such as data centers, hospitals, and industrial facilities. However, the non-linear loads common to UPS systems can introduce harmonic distortions. These distortions not only degrade power quality but may also lead to equipment malfunctions. Y...
