description: The subject of the graduation qualification work is "Computer simulation and analysis of thermal processes in a cast-insulated transformer". This work is devoted to the development of computer models of cast-insulated transformer to find the cause of its damage. The tasks that were solved during the research: Conducting an analysis of accidents associated with cast-insulated dry-type transformers damage. Creating a computer model of cast-insulated dry-type transformer in the software complex EMTP and COMSOL Multiphysics. Calculation of transient and steady-state modes, which may lead to an increase in the temperature some parts of the transformer and cause thermal damage to the insulation of the windings. Based on the studies of processes in cast-insulated dry-type transformers, it was found that some emergency modes can lead to a significant increase in current in the windings and, therefore, to thermal damage to the insulation.
