Learning outcome

After successfully completing the course, the candidate will have achieved the following learning outcomes
defined in terms of knowledge, skills and general competence.

Knowledge
The candidate can:

• Explain breakdown mechanisms in gases and solids
• Explain the functioning and structure of the following high voltage electrical system components: surge arresters, switches, fuses and cable

Skills
The candidate:

• Can calculate lightning voltage in high voltage electricity networks using a travelling wave model
• Can calculate voltages, electric field strength and potentials using computer programs or by hand
• Can carry out work on high voltage electrical installations in accordance with regulations
• Has completed safety training for working with high voltage installations

Course Description

The course describes and explains lightning surges and their effects on electrical grids using travelling wave
models and lattice diagrams. Temporary and switched overvoltages will also be focused on. High voltage
components such as cables, fuses, circuit breakers and surge arresters will be discussed. The physical processes
with regard to the breakdown mechanisms in gases and solids will also be discussed and explained. Relevant
computer programs for calculating complex geometries and lightning voltages will be reviewed.

Teaching and Learning Methods

The learning outcomes will be ensured through a combination of lectures, exercises, excursions and laboratory
work.

Assessment Methods

Computer-exercises and laboratory work must be approved
Final written examination (100 %). Individual grades A-F.

Minor adjustments may occur during the academic year, subject to the decision of the Dean
