Accident analysis in electric grid companies

The problem of accidents occurring during the operation of electric power facilities has remained relevant for a long time. The analysis of accidents makes it possible to develop measures to improve industrial safety at agricultural facilities and electrical networks that supply electricity to agricultural facilities and enterprises. For this purpose, the authors considered accidents that occurred in power grid companies of the Russian Federation in 2014-2022. To conduct the research, they used data from Rosseti PJSC on accidents in power grid companies obtained with the Synergy Center software package. The program included data on the investigation of accidents in Form No. 1 in accordance with the order of the Russian Ministry of Labor dated April 20, 2022, No.223. The software package included 191 accidents, in which 200 people were injured for the period between 2014 and 2022. The analysis revealed 58% of fatal outcomes. The most common damaging factor, which caused 65 accidents (34%), is a breakdown of the dielectric air gap due to violation of the permissible distance to live parts by operational personnel of electric grid companies. The cause of 53 accidents (28%) was the violation of labor safety rules when working with electrical installations. The maximum number of accidents occurred from 8 am to 4 pm during the periods March-May and July-August. Of the 191 injured employees, 114 were (57%) operational personnel (electricians), 108 of them (54%) having work experience from 3 to 10 years. Conclusions are drawn about the need to introduce signaling devices and reverse transformation blocking, improve the qualifications of personnel and train them using virtual reality technology on digital twins of power grid facilities. The proposed organizational and technical measures will reduce the number of accidents in power grid companies in the Russian Federation.
