Active Harmonic Filters (AHF): A Simple Guide to Cleaner Electricity Electricity is part of our daily life. It powers factories, schools, hospitals, shopping centers, and homes. Today, many devices such as computers, chargers, elevators, solar systems, and electric vehicles use advanced electronics. While these devices are useful, they can also make electricity “messy” and harder to co...
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...
