The course starts with fundamental electric field calculations (Laplacian fields) ininsulation systems of simple geometries followed by an introduction to gasdischarge physics, Townsend‟s theory of electric breakdown in air and Paschen‟slaw and its implications on gas insulation strength. A central area of the course isexperimental techniques, which is applied and put into practice during laboratorywork. The concept of insulation coordination connects the different topics in anatural way, and constitutes a theme woven through the course. In addition,knowledge of components in the power system and their characteristics is also ofvital importance for a professional engineer and is therefore dealt with both withtheoretical practices and during a study visit to a nearby sub-station.MTT040 High voltage technology(7.5 credits) Stanislaw GubanskiThis course builds on the knowledge gained during the course in High VoltageEngineering and its aim is to provide deeper understanding of physicalphenomena important for proper functioning of insulation systems in high voltagedevices, as well as for utilizing high voltages in technological applications. Focusis put on the selection of adequate processes and materials yielding desiredelectric properties (breakdown strength, ionisation, conduction and polarisation).Based on this understanding the knowledge on design criteria for insulationdimensioning and principles for insulation diagnostics is built, including elucidationof basic differences between insulation systems for ac and dc applications.Furthermore, students gain insight into technologies using electric discharges.Master thesesDuring the year 33 master theses projects were presented which wereperformed by 44 students. The theses and the participating studentsare presented in the Chapter on publications.21 |
