Power Systems Engineering: Faults, Switchgear, and Protection

Understanding how electrical grids handle faults and protect high-voltage equipment is essential for any aspiring electrical engineer. This text-based course guides you through the fundamental principles of power system analysis, fault calculations, and protective devices. By reading through clear explanations and working through practical scenarios, you will transition from understanding basic circuit theory to analyzing complex power grid anomalies and selecting the right switchgear to prevent catastrophic failures. What you'll learn: - Understand the core terminology of power systems, including symmetrical and unsymmetrical faults. - Calculate fault currents using symmetrical components to assess grid vulnerability. - Analyze the design and operation of fuses, circuit breakers, and switchgear components. - Configure protective relays and understand modern digital relaying concepts. - Explore busbar, transformer, and transmission line protection schemes. - Apply modern safety standards and arc flash mitigation principles to grid design. This course begins with essential terminology, basic grid concepts, and foundational definitions before moving into detailed mathematical fault analysis, switchgear mechanics, and advanced protection strategies. It is designed for beginner electrical engineering students, technicians, and candidates preparing for foundational technical licensing exams, requiring no prior advanced power engineering experience.
