Course Details
The quality of Electric Power is an ever-growing concern today for both utility suppliers and consumers. For that, all system components (Generators, Transformers, Transmission Lines, Feeders, Motors, Bus bars, ..) have to be adequately protected to avoid major system disturbances, which may cause system instability or damage to equipment if faults on the system are not cleared within specified fault-clearing times. Protection of the Power System requires an understanding of system faults and their detection, as well as their reliable and safe isolation from the system. This course presents comprehensive and systematic descriptions of the concepts and principles of the application and operation of protection schemes applied to various power system elements. Many utilities need this course which studies the relay characteristics during faults and weak protection points in electrical power systems.
