Advances in UHV Transmission and Distribution

This course introduces the recent advances in EHV/UHV transmission and distribution systems. The course emphasizes learning and understanding the newer design criteria required for the UHV transmission systems viz: insulation design, protections, safety concerns etc. The course starts with an introduction to the importance of EHV /UHV transmission, its present and future growth. The discussion on the various components used for UHV transmission, design considerations for UHV substations etc are strengthened with the aid of lectures, practical video demonstrations and assignment exercises.INTENDED AUDIENCE : 3rd or 4th year UG, 1st year masters and research studentsPREREQUISITES : Basic Electrical Engg
