Protective relay basics | Eaton PSEC
9:49
Learn everything you need to know about protective relays, the essential devices used to safeguard electrical power systems from faults and abnormal conditions. In this video, Ellen Bachman, District Application Engineer, explains how protective relays function as the “brains” for medium voltage breakers, ensuring faults are isolated quickly to prevent equipment damage and maintain system reliability. Ellen discusses how protective relays work, types of protective relays, and how protective relays are applied in real-world power systems. Understand key ANSI functions, which are essential for designing, operating, and maintaining safe and efficient electrical systems. Ellen also explains zones of protection and how relays are used to protect overlapping sections of a power system. Thank you for watching one of our many educational videos on the topic of power systems.
