Analyzing Traveling Waves in Transmission Lines

When lightning strikes a power line or a switch is flipped, high-voltage transients travel down the system at near the speed of light. Understanding these traveling waves is critical to protecting modern power grids from catastrophic failures. This text-based course guides you through the core physics and mathematical models of wave propagation, equipping you to analyze and mitigate transient overvoltages. What you will learn: Understand the fundamental physics of voltage and current surges in transmission systems; Calculate wave velocity, surge impedance, and propagation constants using standard line parameters; Analyze wave reflection and refraction at junctions and terminations using boundary equations; Evaluate the impact of lightning strikes and switching operations on grid insulation; Explore modern protection techniques, including traveling-wave-based fault location. You will start with foundational electromagnetic concepts and transmission line parameters before moving on to wave equations, boundary conditions, and practical protection strategies. This course is designed for electrical engineering students, power system technicians, and beginners looking to grasp transient analysis with no advanced prerequisites required.
