Abstract

Mathematical reliability model of the electrical system with non-symmetric loaded 2-out-of-3 redundancy is suggested. The model is designed for failure cause analysis of the system. Reliability of the system is formalized by
dynamic fault tree, and probability characteristics calculated based on the split homogeneous Markov model. The main
advantage of the proposed model is adequate consideration of the impact of non-symmetric conditions of the system
failure and load-sharing between components on failure cause probability characteristics of the system
