Abstract

The theme of the thesis is the reliability of switching apparatus, defining the basic concepts and calculation of the basic indicators of reliability. The theoretical part describes the functional status and distribution of devices by using a voltage levels. It outlines the links between laws, regulations and standards, which are important for test or production of switching apparatus. It also provides an overview of the basic indicators of reliability, types of estimates of reliability indicators and the definition of a switching apparatus from the standpoint of reliability models. The end of the theoretical part is dedicated to the technical diagnosis, its distribution, the analysis of the status of the system and the company CEPS, as, which provided the data for reliability analysis. The practical part deals with data collection, distribution reliability analysis and its calculation.
