Access to electricity is expanding globally, but challenges persist. While more people are gaining connections to power grids, issues such as frequent outages and poor power quality remain widespread, particularly in developing regions. Poor power quality, often characterized by voltage fluctuations and inadequate electrical performance, affects millions of users. It hampers their ability to use e...
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...
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...
Clean Power Solutions for Modern Office Towers The power networks in today’s skyscrapers and large office buildings face increasingly complex challenges. From nonlinear loads like elevators, LED lighting, and IT systems to harmonic pollution affecting the power supply's quality, maintaining optimal power quality is critical. This blog explores how the YTPQC Active Harmonic Filters effectivel...
IEEE 519 Harmonic Distortion Limits: Guide to Compliance The IEEE 519-2022 standard, called Harmonic Control in Electric Power Systems, sets rules for designing electrical systems to reduce harmonic distortion. What Does the Standard Do? IEEE 519-2022 helps engineers manage harmonics in power systems. It covers both linear loads (like motors and regular light bulbs) and nonlinear loads...
As the world accelerates its transition toward low-carbon and sustainable energy systems, the integration of renewable energy—such as solar, wind, and hydropower—has become a central pillar of national energy strategies. However, this rapid shift has introduced new challenges to the stability and reliability of power systems. One of the most critical concerns is power quality&md...
Power Quality: Why It Matters and How YT Electric Provides Solutions What Is Power Quality, and Why Should We Care? In 2001, a Silicon Valley manufacturing company lost over $3 million in a single day due to a power outage that halted production.¹ Today, nearly 20% of the world’s electricity is wasted due to inefficiencies in power transmission and distributio...
