Harmonics, caused by non-linear loads such as electronic devices and power electronics equipment, are becoming a growing concern in modern power systems. These unwanted distortions can lead to voltage fluctuations, increased energy losses, equipment overheating, and even interference with communication systems.

Left unaddressed, harmonics can shorten equipment lifespan, reduce efficiency, and raise operational costs. Understanding their impact and adopting proper mitigation techniques is essential to ensure stable, efficient, and reliable power delivery while minimizing risks to both users and the environment.
