Not applicable.

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.

The subject knowledge on the secondary school level is required.

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.

2. Reliability of elements and systems.Classification of systems.Classification of failures according to their reasons of origin, time course and stage of the failure.
3. Bases of statistics.Distribution of random variable and their use in reliability.
4. Reliability of expendable.Probability of trouble-free operation.Probability of failures.Density of failures, intensity of failures.Mean time of trouble-free operation.Relations between characteristics of reliability.
5. Reliability of systems.Creating reserves.Active and passive creating reserves.
6. Standardization.Statistics at checking of quality of production processes.International standardization.
7. Introduction of ISO 9000 quality system.
8. Defects in initial materials and their influence on final properties of elements.Defects iniciated by production technology.
9. Mechanisms and kinetics of processes of ageing and depreciation.Interaction between the conditions of exploitation and electrotechnical equipment. Complex,partial and model stresses and their relation to depreciation.
10. Temperature ageing. Effect of humidity.Ageing by electric field.Mechanical depreciation.Effect of chemically agresive environment.
11. Corrosive depreciation.Kinetics of degradation processes at affecting degradation factors.
12. Diagnostics of materials,elements and systems.Destructive,potentially destructive and non-destructive methods.
13. Structural methods.Electrical methods.Other physical methods.

Not applicable.

The aim of the subject is to make students familiar with the problems of reliability of electrotechnical products and with the bases of creating reserves.

The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.
