The student is able to:
- define the basic concepts of reliability,
- explain ways to backup systems,
- describe the stress involved in the operation of electrical equipment and subsequent aging electrical systems,
- explain the methods of reliability,
- calculate selected indicators of system reliability,
- can interpret basic reliability models.

None.

Not applicable.

Techning methods include lectures, computer laboratories and practical
laboratories. Students have to write a single project/assignment during the course.

upto 20 points from seminars (student will receive these points by the individual work in the field of reliability and its presentation).
upto 80 pointsfrom written examination.
The test focuses into the issues of reliability discussed in lectures and seminars.
