This document outlines the course plan for EE 1004 - Power System Transients. The course is divided into 5 units that cover various types of power system transients including switching transients, load switching transients, lightning transients, travelling waves on transmission lines, and transients in integrated power systems. It provides example topics that will be discussed in each unit such as the effect of transients, resistance switching, capacitance switching, lightning phenomena, and travelling wave concepts. The document also lists potential assignment topics and seminar topics for students. It is taught by Professor R. Hariharan of the Electrical Engineering department.
