Introduction Modern industrial and commercial electrical systems increasingly use devices with nonlinear characteristics. Even with sinusoidal voltage, nonlinear devices draw distorted currents, causing harmonics. These harmonics lead to: Nonlinear loads generating harmonics include: Impact of Harmonics a. Grid Side b. Customer Side c. Power Factor Harmonics reduce the effectiveness of conventional power factor correction. True […]

Introduction In modern industries, electrical energy is the lifeline. Hidden within are distortions—harmonics—that silently drain efficiency, damage equipment, and inflate costs. Industries with VFDs, furnaces, robotics, IT servers, and renewable integration face harmonics not as a minor concern, but as a serious business risk. What Are Harmonics? Harmonics occur when the current deviates from a
