How the transmission lines are protected? | 3 Zone Protection | Electrology

Explore the fascinating world of power systems and discover the critical role of distance protection in maintaining grid safety! This video delves into the complexity of power systems, highlighting their vulnerability to faults and the severe consequences, such as blackouts and equipment damage. Learn how distance protection works as a rapid response system to isolate faults and keep the grid stable. Through engaging analogies and expert explanations, we illustrate how distance relays operate based on Ohm's Law to detect and locate faults accurately. Understand zones of protection, coordination among relays, and real-life fault scenarios that showcase the importance of distance protection in enhancing grid resilience and safety.
