In the paper, a mathematical reliability model for an electrical repairable system with parallel load-sharing redundancy of components is proposed. Such a model adequately accounts for the impact of load-sharing redundancy on cut set probability indexes. For reliability modelling, both dynamic fault tree and Markov analysis are used.
