Physical-Technical Fundamentals
The working group Physical-Technical Fundamentals focuses on the modeling and analysis of the behavior of equipment and subsystems in electrical power grids.
Key areas of research include, for example, the modeling and optimization of the frequency-dependent transmission characteristics of transformers and conventional instrument transformers. This has gained importance with the increasing use of vacuum circuit breakers and power electronic devices in power networks, which generate high-frequency interference. Such interference must be transmitted by instrument transformers with sufficient accuracy and withstood by power transformers.
Additional projects involve modeling the transmission characteristics of current transformers while considering remanence effects. Furthermore, a computational framework is being developed to efficiently calculate and analyze the spreading resistance of grounding systems in soils with inhomogeneous conductivity.
