Modeling traumatic situations when using electric mobile machines in power generation facilities

The article analyzes the development of electric power in the country. The causes of the dangerous technogenic situations connected with emergence of accidents, the fires and electric traumas on these objects are specified in the work. It offers modeling of traumatic situations when working with an electric mobile machine. The authors consider electro-frequency analysis with the description of its structure. The principles of tree charts construction with the description of the qualitative analysis of the modelled technological process are provided in the research. The authors analyze the main prerequisites reflecting interrelations in a security system of mobile electrical installation, namely state of environment, existence of an electrical protection system, ways of a person ’s electrocution, an electric trauma outcome. They carry out the quantitative analysis of tree charts with definition of aprioristic assessment of numerical parameters when modeling dangerous situations. The work determines the probability of accidents ’ occurrence with a description of the causes of potential hazards when working with manual electric perforator. The structure of events and outcomes’ trees creation and electrical traumatism signs are analyzed in the paper.
