| Versions for this Unit: |
| Campus: | Camperdown/Darlington |
| Pre-Requisites: | ELEC3105. |
| 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 |
| Assumed Knowledge: | ELEC3105. The following previous knowledge is assumed for this unit. Circuit analysis techniques, electricity networks, power system fundamentals. |
