Course lecturers



Explain to students how to determine the characteristics of a switchgear and their correct selection for a particular installation location in the power system, while satisfying the required power and voltage conditions. Students are able to define and recognise specific construction-related problems and the choice of high-voltage components.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. understand the types and uses of switchgears in power plants

2. apply the underlying concepts related to the electric field and penetrates in homogeneous and non-homogeneous electrical fields

3. summarise transient phenomena and interactions between a switchgear and power grid

4. evaluate the test results obtained by artificially produced high DC and alternating voltages in a high-voltage laboratory

5. using a computer, create a short-circuit current breaker to appropriately select the circuit breaker at the observed site in a power plant

6. create computer models for calculating electrodynamic and thermal stresses in switchgears
