ELEC5205: High Voltage Engineering (2013 - Semester 2)
|Unit:||ELEC5205: High Voltage Engineering (6 CP)|
|Faculty/School:||School of Electrical and Information Engineering|
Dr Sathiakumar, Swamidoss
|Session options:||Semester 2|
|Versions for this Unit:|
|Pre-Requisites:||ELEC3203. The following previous knowledge is assumed for this unit. Circuit analysis techniques, electricity networks, power system fundamentals.|
|Brief Handbook Description:||The unit provides advanced knowledge associated with high voltage engineering methods, techniques and equipment. It is divided into two parts. Part 1 (8 weeks) presents fundamentals of the failure mechanisms of solid, liquid and gaseous insulation at high voltages. It also discusses consequent design principles for high-voltage equipment; of the generation of high direct, alternating and impulse voltages for testing high-voltage equipment; and of methods for monitoring and assessing the condition of high-voltage equipment such as dissolved gas analysis for oil-filled transformers and partial discharge in cables. Part 2 (5 weeks) presents high-voltage equipment in practical detail, and, in particular, underground cables, overhead transmission lines, transformers, bushings and switchgear. It finally offers asset management solutions for modern transmission and distribution electricity networks.|
Professor MacAlpine, Mark
Dr Mitchell, Keith
|T&L Activities:||Tutorial: Tutorials on past exam questions, practical examples and industrial case studies.
Laboratory: an interactive small-group demonstration of high-voltage phenomena
Project Work : 3-week ‘paper research’ report (not timetabled)
Independent Study: Parts of the work will not be covered in the lectures, and will need to be understood from the lecture notes. Review of industrial standards and applications, industrial case studies
