Course Introduction
Understanding Harmonics in Power Systems: Causes, Effects and Elimination Methods is essential for maintaining high Power Quality in modern electrical infrastructures. As industries shift toward Variable Frequency Drives (VFDs), UPS systems, and LED lighting, the prevalence of Non-linear Loads has introduced significant distortion into the sine wave. This course provides a comprehensive technical breakdown of how Harmonic Currents and Voltage Distortion degrade system performance and how to implement effective Harmonic Mitigation strategies.
In this program, we analyze the root causes of Harmonic Distortion, ranging from Rectifiers and Inverters to saturated Transformers. You will learn to calculate Total Harmonic Distortion (THD) and understand the severe effects on equipment, such as Transformer Overheating, Neutral Conductor Loading, and nuisance tripping of Circuit Breakers. By mastering Elimination Methods—including Passive Harmonic Filters, Active Power Filters (APF), and Multi-pulse Converters—you will ensure compliance with global standards like IEEE 519 and protect sensitive electronic components from premature failure
