About this course

Content

  • Calculations of design criterias for highvoltage insulation
  • Calculations of the electric field strength in various configurations
  • Calculations of Lightning overvoltages and Switching overvoltages and knowledge about protection against these overvoltages.

Knowledge of the structure of the components of:

  • Distribution networks with distribution network station
  • Regional grid with transformer station
  • Main Grid with switchgear

Learning outcomes

After completing the course the student is meant to have:

  • the theoretical basis for calculating voltage stresses in electrical high voltage grid.
  • the theoretical basis for calculating voltage drop and losses in power grids.
  • the theoretical basis for designing measures to reduce voltage drop and network losses.

After the course the students should have knowledge about:

  • infrastructure, voltage levels and use of components and equipment for high voltage transmission and distribution in Norway.
  • material properties that are important for electrical stress of high voltage insulation and the most widely used insulation materials.
  • simplified theoretical models for calculating estimates of stresses of electrical equipment during normal operation, temporary overvoltages, atmospheric surges and switching surges in the grid
