Modern power systems face a hidden threat: resonance. This occurs when harmonic currents from non-linear loads (like VFDs and rectifiers) match the electrical system's natural frequency. The result? Dangerous amplification of harmonic voltages and currents, leading to capacitor failures, overheating, and equipment damage. Traditional passive filters can ironically cause this problem by introducing...
AHF & SVG Demystified: The Simple Guide to Smarter Power If you operate a factory, you've probably heard of power quality. You might have also heard about Active Harmonic Filters (AHF) and Static Var Generators (SVG). They sound technical, but their purpose is simple: to save you money and prevent headaches by fixing bad power. Think of your electrical supply as the water to your home. You exp...
How Does a Static Var Generator Help Stabilize Voltage? Electricity is a very important part of modern life. It powers our homes, schools, hospitals, and factories. For electricity to work safely and efficiently, the voltage must stay stable. If voltage is too high or too low, electrical equipment may not work properly or may even be damaged. In this article, we will explain what voltage is, what ...
Is Your Electricity "Dirty"? AHF vs. SVG Explained Simply Have you ever seen lights flicker for no reason? Has your computer or factory machine suddenly shut down? You might blame the equipment, but the real problem could be the electricity itself. Just like water can contaminate, electricity can become "dirty" or unstable. We always call this poor power quality. It doesn't mean the power is off; ...
Medium-Voltage SVG: A Core Device Empowering Power Quality Optimization in Modern Power Grids With the large-scale grid connection of new energy power generation, the surge in industrial impact loads, and the continuous improvement of users' requirements for power quality, medium-voltage power grids are facing many challenges such as reactive power imbalance, voltage fluctuation, and harmonic poll...
The Principle of High-Voltage Passive Filtering In high-voltage power systems, the widespread application of non-linear loads such as electric arc furnaces, frequency converters, and rectifiers generates a large amount of harmonic currents. These harmonics not only cause power grid voltage distortion and increase line losses but also may interfere with the operation of precision equipment and dama...
The Ultimate Solution for Power Quality ---SVG & AHF Reliable power quality is key for efficient work in today's factories and businesses. Two main issues often come up: harmonic distortion and wasted reactive power. Here are two advanced technologies can solve these problems: Active Harmonic Filter (AHF) and Static Var Generator (SVG). They help reduce risks and make power systems work better...
Data Center Power Quality: Harmonic Mitigation Case Study Modern data centers rely heavily on sensitive electronic equipment. Servers, storage units, and networking gear use non-linear power supplies. These components generate significant harmonic distortion within the electrical system. High harmonic levels lead to equipment overheating and unexpected downtime. A major facility recently fa...
