In this educational video, I explore the decision-making process of a directional overcurrent relay using an interactive visualization and an example. Learn how the relay interprets current and voltage vectors in power systems and makes trip decisions based on the X/R ratio and other parameters.

Key topics covered in this video:

Learn how a directional overcurrent relay analyzes current and voltage vectors to protect power systems effectively. This video includes an interactive visualization to demonstrate trip and no-trip zones, the role of polarizing voltage, and the importance of the X/R ratio. Gain step-by-step insights into relay decision-making to deepen your understanding of power system protection.

Whether you're an electrical engineering student, power system professional, or just curious about how directional overcurrent relays work, this video will provide you with valuable insights and hands-on experience.
