Model of building the optimal safety structure of electrical installations on agricultural sites

The article considers the method of building the optimal electrical safety system at agricultural facilities. The stages of modeling traumatic situations in the operation of electrical installations are given. Model building analysis of the type of "tree of accidents" when working with mobile electrical engineering on the basis of the occurrence of traumatic situations with the probability of electro-injury, based on statistics, was carried out. As a result of the simulation performed for the case "Electric injury when touching the body of a mobile electrical installation", the probabilities of two groups were determined: the event tree and the outcome tree. Based on the above modeling method of the "tree" type, three variants of protective measures are presented, aimed at creating an optimal safety system for mobile electrical engineering. When comparing and choosing the best option, a quantitative assessment was given according to the cost-benefit principle, and the initial and unrepaired damage were determined.
