ELK 473 - Discharge Phenomena in High Voltage Techniques

Course Objectives

1) In order to minimize power losses in energy transmission and distribution systems , line voltages have to be continuously increased. As a consequence of this discharge phenomena in high-voltage techniques became a basic field of study for electrical engineers .
2) Thus the knowledge of the properties of gases , vacuum and plasmas , as well as of liquid and solid dielectrics , is of fundamental importance in high-voltage technology.
3) The main purpose of this course is to deal with theoretical and experimental study of breakdown mechanisms in gaseous , liquid and solid dielectrics.
