COURSE OBJECTIVE
Reliability of electrical energy systems to a large extent is a consequence of the reliability of it’s protection system. Basic building blocks of the protection system are fuses, over current and distance relays and differential protection schemes. In this course, we will introduce their principles and applications to apparatus and system protection. Technology of relaying has changed significantly in last century. The first generations of relays were electromechanical devices. The second generation involved solid state relays. The present generations of numerical relays are realized by digital signal processing. In this course, we will also introduce both theory and practice of the numerical relays.The course can be used as a first course in power system protection. It should be also useful to graduate students, practicing engineers as well as the research community.
