Analysis of emergency events as a result of human errors during the operation of electrical equipment in power grids

The continuous development of electric power systems in terms of implementation of new technologies for management and connection of new sources of energy makes the problem related to improving the security of power supply relevant. One of the common reasons causing power outages in the power grids is the human error of the maintenance and operating personnel. The present work is dedicated to the investigation and analysis of real emergency events with injured people caused by human errors in the operation of electrical equipment in power grids and substations. Based on the analysis, measures are proposed to prevent similar human errors.
