Abstract
The paper presents the reliability parameters of the devices, used in relay protection systems and switching equipment. A methodology has been developed for evaluating the reliability of these devices in case of supplying a consumer according to a scheme with automatic engagement of the backup power supply. A mathematical model for evaluating the parameter of the flow of failures with respect to the load has been obtained, taking into account the reliability of the aforementioned devices in the described case. The mathematical model is compiled by applying the theory of planning experimental research.
