Power System is regular course of Bachelor in Electronics and Communication Engineering and is assigned for Fourth Semester. IOE has designed the syllabus of Power System with the objective to deliver the principle and fundamental analysis techniques for generation, transmission and distribution components of a power system with basic protection system. The subject code of Power System is EE 553.
