The problem of reliability of relay protection systems and automation is considered. Based on the analysis results, for the construction of automation systems, a number of mathematical expressions have been proposed that allow at the design stage to assess the fault tolerance of the power supply system with the selected protection devices, thereby simplifying the process of choosing the most preferred system based on the obtained indicators.
