The technical equipment of the High-Voltage Laboratory is unique in the German landscape of higher education institutions, and it is used for research and development projects both publically- and privately-funded. Thus, the Institute for Power Engineering and High Voltage Technology (IEHT) and the High-Voltage Laboratory contribute significantly to the profile of the Faculty of Electrical Engineering and of FHWS.
Special competences lie in the fields of dielectric materials (oil, board, paper, RIP, SIR), the design of insulator systems (HVDC, HVAC, BIL) and condition diagnosis (PDC, KFT, measuring space charge using the Kerr effect and PEA method), damage analysis for equipment used for energy supply (transformers, feedthroughs) and in the application of high-voltage technology for industrial purposes.
Our partners are technologically leading companies, higher education institutions, the German Research Association (DFG), the Federal Ministry of Education and Research (BMBF), the Industrial Research Associations (AiF) or the Fraunhofer Society.
Through their involvement in scientific panels (e.g. in CIGRÉ Working Groups, the ETG subject area ‘cross-sectional technologies Q2’: Materials - Insulating systems - Diagnostics, the Würzburg Research Association for Functional Materials WFF) and through many co-operations, a close network between science and the economy is knit. Please find an overview about the latest publications on the IEHT website.
Current research areas of the IEHT and the High-Voltage Laboratory are:
Insulation materials and systems for high-voltage direct current transmission (HVDC)
... as in future, three-phase current grids worldwide will reach their performance limits, and need to be connected via HVDC technology.
Research fields:
- Measuring space charges using the quadratic electro-optic Kerr effect
- Measuring space charges using the Pulsed Electro Acoustic (PEA) method
- Determining conductivity through precise measurements in guard-ring electrode arrangement
