Modelling of Switchgear Reliability Using Bayesian Networks Based on Interval Probabilities

Abstract

Increasing reliability and assessing remaining life of the switchgear is one of the most important tasks in order to ensure proper work of a power system. Replacement of the most critical circuit breakers represents a good basis for increasing the reliability of the energy system. This paper proposes a model for determining optimal time for replacement of existing circuit breakers using Bayesian networks based on interval probabilities.
