This course covers two critical aspects of electrical systems—Power Quality (PQ) and Electromagnetic Compatibility (EMC). Power Quality addresses the stability and reliability of power supply, focusing on minimizing disturbances like voltage sags, swells, and harmonics that can affect equipment performance. Electromagnetic Compatibility, on the other hand, examines how electrical and electronic systems coexist without interference, ensuring that devices operate efficiently and safely within their electromagnetic environment. Together, these topics are essential for developing robust and reliable electrical systems, particularly in modern, technology-driven environments.
