How to Measure Power Quality Efficient energy use is a key goal for organizations and institutions that generate, transmit, and distribute electricity. Improving efficiency requires better power quality, otherwise, it can harm electrical systems. Measuring power quality is essential to identify and fix these issues. Accurate measurements from correct points are critical. I. Introduction Mos...
Introduction Power quality refers to the characteristics of electric power supplied to end users, particularly its ability to ensure the proper functioning of electrical devices. With the increasing use of sensitive equipment such as programmable logic controllers, variable frequency drives (VFDs), and computers in modern industries, the tolerance for power disturbances such as voltage dips, swell...
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...
What are Reactive Power and Reactive Power compensation？ Reactive power is a key part of AC electrical systems—it’s the energy that flows back and forth between the power source and the load. Unlike active power, which does the actual work like powering lights or running machines, reactive power doesn’t directly get used up. But it plays a crucial role in keeping voltage levels s...
Before diving into the architecture and types of battery energy storage systems (BESS), it is essential to familiarize ourselves with key terminology commonly used in this field. Various parameters are crucial in describing the behavior and performance of BESS. · Capacity [Ah]: This represents the amount of electric charge the system can supply to a connected load while maintaining an accep...
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...
