Ausgewählte technologische Entwicklungen in der Hochspannungstechnik

High-voltage engineering faces new challenges due to arising changes in energy policy. As a key technology, it needs to provide a sustainable, reliable, environmentally friendly as well as an efficient supply of electrical energy. This paper highlights selected technological developments in high-voltage engineering. New, environmental friendly gases and gas mixtures, biological or synthetic insulating liquids as well as new solid insulation systems are of particular importance. Additionally, nanotechnology has a strong impact on these developments within the area of nanodielectrics and nanofluids. Furthermore, there are new approaches in measurement techniques and diagnostics which are essential for equipment quality, for example partial discharge diagnosis or the determination of electrical conductivities of various insulation materials.
