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
equ...ipment or labor.
