ECE 581 Electric Power System Protection
3 Credit Hours
Protection systems used to protect the equipment in an electric power system against faults, fault analysis methods, basic switchgear used for protection, basic protection schemes, such as overcurrent, differential, and distance protection and their application. To introduce the current industry practice, the course will have a few guest lecturers from industry.
