Primary Technology and Diagnostics
Contact
With its work, the team Primary Technology & Diagnostics contributes to a safe and reliable operation of current and future electrical networks. The main research areas include technical requirements for the primary technology of electrical networks, the development of minimally invasive diagnostic procedures and the testing and development of data-driven asset management strategies. Extensive experimental possibilities are available to answer the resulting questions. These range from synthetic test circuits for investigations on HV power switches and MV load break switches to a continuous test field for conductor technologies and a test laboratory for determining the human perception threshold of electric fields. In addition, there is an innovative test laboratory for the generation of DC fault cases with an energy of 1.92 MJ, which generates a maximum fault current of 30 kA at 8 kV. The experimental work and the in-depth theoretical analysis based on the modelling of physical processes is supported by a variety of simulative investigations.
