До питання діагностування силового трансформатора

Abstract

There had been suggested an approach to determine the impact on the process of power transformer coils insulation aging under the influence of short time internal and external actions. It had been demonstrated that the heating of coils takes place upon the completion of the short time energy pulse. The paper suggests to evaluate the coils temperature and take it into consideration for the determination of tearing the operation resource of the power transformer coils, using the heat conducting theory.
