Safeguard modern electrical grids by mastering the essential techniques to detect faults, coordinate protective relays, and prevent catastrophic equipment failure.
Power system protection is one of the most critical functions in electrical engineering. When faults are not detected and isolated correctly, the consequences can include equipment destruction, prolonged outages, cascading failures, and major safety risks across substations and distribution networks. Yet effective protection requires more than understanding relay theory — it requires knowing how protection systems behave in real operating environments.
This practical session examines protection engineering from a real-world substation and distribution network perspective. It covers fault analysis fundamentals, relay operating principles, relay coordination strategies, protection schemes for transformers and feeders, CT and VT applications, and the commissioning and testing practices used to ensure protection systems operate reliably under fault conditions.
