- Abstract
In this paper, remaining useful life (RUL) of circuit breakers (CB) has been analyzed, based on statistical data gathered during CB's maintenance. Using statistical data of 427 CBs gathered in past 10 years, Weibull probability distribution of contact resistance for breakers on both overhead and underground feeders and voltage levels of 35 kV and 10 kV is determined. With this methodology CB's condition can be observed by using real field data which are collected regullary during power station revision.
