Abstract
In my bachelor thesis I have to make diagnostcics about condition of high voltage circuit breaker from electrical substation in Albrechtice. I started with description of circuit breakers. Then I focused on technical diagnosis and its methods, specifically diagnosis of HV circuit breakers. From diagnosis protocols, which I obtained, I described actual condition of the circuit breaker. In conclusion I described residual reliability of HV circuit breakers and tried to compare catalogue values from different companies.
