Introduction to Power Quality in Modern Electrical Systems

Power quality issues can disrupt operations, damage sensitive equipment, and lead to massive financial losses in modern electrical systems. Understanding how to diagnose and resolve these disturbances is essential for anyone working with electrical power today. This text-based course guides you from the foundational principles of electrical anomalies to practical mitigation strategies. You will develop a solid understanding of voltage sags, harmonics, and transients, enabling you to maintain system reliability and comply with international standards. What you'll learn: Understand core power quality terminology, definitions, and standard parameters; Identify the causes and consequences of voltage sags, swells, and transient interruptions; Analyze harmonic distortion in power networks and its impact on modern electronics; Apply mitigation techniques using passive filters, active power filters, and surge protection; Evaluate power quality in the context of renewable energy integration and smart grids; Reference international standards such as IEEE and IEC to ensure system compliance. Starting with foundational concepts of wave shapes and electrical anomalies, the course progresses systematically through monitoring techniques, mitigation equipment, and modern grid challenges. Each section provides clear, written explanations and practical scenarios to build your analytical skills. This course is designed for beginner electrical engineers, technicians, facility managers, and students seeking a clear entry point into power system engineering, with no advanced prior experience required.
