Analysis of Weibull and Poisson Distribution use in Medium Voltage Circuit Breakers RUL Assessment

Abstract

In this paper, Weibull and Poisson distribution conclusion are they suitable for circuit breakers remaining useful life assessment (RUL). Old data are covering a 10 years period consisting of measured voltage drop on CB contacts and number of tripped short circuit faults. In this paper, new data, from the last 3 years, would be used to make a comparison with old data and make conclusions have been probability distributions correctly chosen.
