Abstract

This bachelor thesis is making the reader acquainted with the diagnostics on high voltage circuit breakers as well as with the problematics of how to measure their reliability and usability in the practical applications. First part of this thesis is ment as a summary of basic theories and practical applications of those as needed to perform a successful measurement and comparison of gathered data in field conditions. Last part of this chapter is aiming at specific needs for a high voltage circuit breakers in terms of technical diagnostics. The second chapter is a list of criteria, that are important in process of considering a quality and reliability of high voltage circuit breakers, paying special attention to correct sorting, according to their types and working state. Last part of text is an enumeration of the methods, that might be used in the practical application while measuring these items, as well as diagnosis of the gathered data.
