Intended learning outcomes

After fulfilment of all course requirements, the student should be able to

  •  describe the puropose, need, principle function and design of different power components
  •  make mathematical models that can be used for calculation of:
    • propagation of over-voltage transients in the power system.
    • transient and stationary short-circuit currents and related induced overvoltages for different fault situations.
    • transient overvoltages and currents in different connection/disconnection situations.

The models should be applicable on linear as well as non-linear systems and components, as for example treatment of surge arresters and magnetic cores.

  • transient voltage distributions in components of distributed nature like transformer windings and cables.
  • describe different type of neutral groundings
  • describe different methods for overvoltage protection
  • calculate different probabilities that a certain overvoltage cause breakdown (insulation coordination)
  • understard which properties that has an impact on the reliability, availiability and life-time of the power components
  • present an overview of possible stresses on power components and understand the relation between stresses, dimensioning (thermal, electrical, ambient and mechanical) and material selection.

One should know how the power components are affected by their surrounding environment and vice versa.

One should have some insight in the laws, regulations and standards that affects the design of a power system.

  • discuss the most common mechanisms behind long-term ageing of power apparatuse and propose diagnostic methods that can be used in order to detect the ageing.
