How AHF Prevent Harmonics and Resonance in the Power Grid Introduction In today's increasingly electrified world, power quality issues like harmonics and resonance are becoming more prominent in industrial and commercial settings. These issues can lead to equipment malfunctions, energy inefficiencies, and costly downtimes. An effective solution lies in Active Harmonic Filters (AHFs),...
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...
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...
