Abstract (en)
The main goal of this dissertation is to estimate the remaining useful
life of minimum oil circuit breakers (CB) based on data collected
during their regular inspection.
Using the proposed approach, CB’s with the highest risk can be
identified, whose failure can cause the greatest economic
consequences, but also consequences for the stability of the power
system. By determining the reliability and risk of minimum oil CB’s,
it is possible to see what influence has the place of installation on the
aging process. In this way, a correlation is established between the
values of voltage drops and other categories such as: feeder type,
voltage level, year of production, number of disconnected short-circuit
currents.
The end result of the CB’s analysis is the possibility of knowing its
aging process, classification of the state of all CB’s based on the risk
of failure, knowledge of the impact of CB’s replacement on the
availability of the power station, without additional investment in new
equipment or labor.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
