Active Harmonic Filters: The Smart Way to Fix Harmonic Distortion Harmonic distortion is one of those hidden issues that can quietly wreak havoc on your electrical system. It’s responsible for things like overheated transformers, motor failures, and unexpected equipment shutdowns. If your facility uses a lot of variable-speed drives or other nonlinear loads, chances are you’ve s...
In today’s increasingly digital and power-electronic-driven world, understanding power quality parameters is essential—especially for engineers, technicians, and facility managers. One such important metric is THDi, or Total Harmonic Distortion of current. But what exactly is THDi, and how does it occur in electrical systems? What is THDi? THDi stands for Total Harmonic D...
Active Harmonic Filters (AHFs) are widely used in buildings to mitigate harmonic distortion caused by non-linear loads, ensuring power quality, energy efficiency, and compliance with standards like IEEE 519 and IEC 61000-3-6. Here are key applications of AHFs in buildings: 1. Office Buildings & Commercial Complexes Loads: LED lighting, VFDs (HVAC systems), elevators, UPS systems...
From data centers in Frankfurt to EV charging stations in Southeast Asia, Active Harmonic Filters (AHFs) are rapidly becoming the gold standard for solving one of the most overlooked yet costly problems in industrial power systems—harmonics. Modern electrical loads such as variable frequency drives, inverters, and switching power supplies generate non-linear current waveforms, resulting in h...
Modern industry runs on precision—yet harmonic distortions, voltage fluctuations, and reactive power imbalances remain costly adversaries. These silent disruptors erode efficiency, inflate energy bills, and jeopardize compliance. Enter the YTPQC-AHF Active Power Filter (APF): an intelligent solution engineered not just to mitigate power quality issues, but to eliminate them at thei...
Have you ever heard of "harmonics" in electrical systems? If not, it’s time to pay attention—because these invisible distortions could be silently eroding efficiency, damaging equipment, and inflating energy costs. But what are harmonics, exactly? Think of electrical current as a symphony: ideal current flows smoothly in a single "note" (frequency). Harmonics are unwan...
Harmonics are a critical yet often overlooked phenomenon in electrical systems. They represent distortions in the ideal sinusoidal waveform of voltage or current, occurring at frequencies that are integer multiples of the fundamental power frequency (e.g., 50 Hz or 60 Hz). While harmonics are inherent in modern power systems, their uncontrolled presence can lead to severe operational and financial...
