Seminar 12

August 21, 2008

1:00 to 2:00 PM

What should we be teaching our undergraduates about Relaying?

Joseph Mooney - Schweitzer Engineering Labs

"Large disturbances such as short circuits occur in power systems from time to time and cannot be avoided. The goal of the protection system is to prevent or minimize damage to the system and to remove hazardous conditions during such disturbances. In three lectures students are introduced to the basic protection principles as applied to the elements of power systems. Overcurrent, directional, distance, pilot, and differential concepts are explained, their inherent advantages and disadvantages, and typical applications. The benefits of digital relays are identified together with some directions for future improvements."
