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...
Power Quality Evaluation: The Cornerstone of Stable Solar PV System Operation As solar photovoltaic (PV) systems gain widespread adoption in commercial and industrial settings, interest in financial returns and performance expectations has intensified. However, a critical yet often overlooked aspect throughout the entire lifecycle of solar projects—from planning and installation to oper...
