Microvaristors in Polymer Insulation Systems -- Clarification of Possible Applications in Electrical Power Engineering and Investigations of Operating Behavior

Project description

In this applied collaborative research project, funded by the Arbeitskreis Industrieforschung (AIF), suitable simulation tools are to be developed for the theoretical preliminary clarification of potential applications of novel microvaristor-filled polymeric insulating materials. For this purpose, test and model arrangements as well as characterizing test methods will be developed together with the project partners. Promising applications will be realized and experimentally investigated in sub-working groups. Processability issues should be addressed, including aspects such as manufacturing reliability, repeatability, and consistency of electrical and mechanical properties. Finally, the complex aging behavior/lifetime will be addressed with the aim of developing suitable requirements and test methods. In addition, new microvaristor-filled or microvaristor-coated insulation systems such as coated long rod insulators, end glow protection systems in electrical high-voltage machines and cable terminations will be investigated with respect to this behavior and optimized if necessary. A comparison should always be made with materials and arrangements already available on the market in order to evaluate the advantages and disadvantages of the new material from both a technical and an economic point of view. The chair TET contributes to the development and application of suitable numerical simulation methods for nonlinear microvaristor-filled functional layers for the development and optimization of refractive field control in complex components of high-voltage technology. The basis of this research is the finite elements research simulation package MEQSICO (Magnet-/Electro-Quasistatic SImulation COde) developed at the chair TET.
