Overcurrent Protection in Electrical Substations: the simple genius of the Relay

Courses: https://www.udemy.com/course/introduc... Although digital relays have replaced their older electromechanical counterparts, the terminology and theory of operation remains the same. In fact, to properly understand digital relays, a good working knowledge of the physical principles underpinning the electromechanical relay is required. This video is a simple introduction to how overcurrent protection works in electrical substations, with emphasis on the electromechanical relay. We will look at the role of relays in overcurrent protection, the current transformer, relay settings (plug setting, time multiplier) and discrimination.
