KommentarThe lectures High Voltage Engineering I: Experimental Techniques (227-0117-10L) and High Voltage Engineering II: Insulation Technology (227-0117-00L) can be taken independently from one another.

KurzbeschreibungHigh electric fields are used in numerous technological and industrial applications such as electric power transmission and distribution, X-ray devices, DNA sequencers, flue gas cleaning, power electronics, lasers, particle accelerators, copying machines, .... High Voltage Engineering is the art of gaining technological control of high electrical field strengths and high voltages.
LernzielThe students know the fundamental phenomena and principles associated with the occurrence of high electric field strengths. They understand the different mechanisms leading to the failure of insulation systems and are able to apply failure criteria on the dimensioning of high voltage components. They have the ability to identify of weak spots in insulation systems and to propose options for improvement. Further, they know the different insulation systems and their dimensioning in practice.
Inhalt- discussion of the field equations relevant for high voltage engineering.
- analytical and numerical solutions/solving of this equations, as well as the derivation of the important equivalent circuits for the description of the fields and losses in insulations
