Department of electric power engineering

Power Technology

The main activity of the group is related to design, modeling and operation of electric power components. With close working links with industry, research into better insulation materials, both for ac and dc, is being conducted. 

Within the Power Technology Group there is ongoing research and development of new technology and expertise in the following fields.

Insulation materials

  • Cable insulation technology.
  • Subsea connector technology.
  • Switchgear technology.
  • HVDC.

Analysis of stresses

  • Finite element analysis. Multiphysics.
  • Electromagnetic compatibility.
  • EMTP modelling and simulation. Analysis of disturbances, harmonics, transients.
  • Insulation coordination and lightning studies.
  • Simulation tool developments (ATPDraw).
  • Component modelling; transformers, cables, machines, converters, circuit breakers.

Component designs

  • Hydro power generators.
  • Power transformers.
  • Power electronics and power converters.
  • Circuit breakers and switchgear.
  • Electrical machine designs.
  • Maritime and industrial electrical intallations. Offshore and subsea power supply.


  • Relay protection and substation automation.
  • Electric installations in buildings, lighting.
  • Current interruption, AD/DC.
  • Condition monitoring and maintenance. Asset management.
  • Integration of renewables
