This presentation provides a practical, engineering-level overview of the key components that form the backbone of modern power system protection and substation automation in a 138 kV transmission environment.

The session begins by examining the role of protective relays (IEDs) in detecting faults, executing high-speed tripping logic, and ensuring selective fault isolation. It then explores how RTUs and station gateways interface field devices with SCADA systems, enabling real-time monitoring, control, and event analysis from remote control centers.

This session also introduces the fundamentals of Low Voltage Motor Control Centers (LV MCCs) used in industrial plants, utilities, and infrastructure facilities.
