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 outcome

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
