چکیده :
Transformer is one of the vital and very important equipment in electrical networks. Their exit from the circuits will cause a lot of damage to the network and will reduce the reliability of the network. The expansion of nonlinear loads and the increase of harmonics in the distribution networks cause an increase in losses and an increase in the hot spot temperature and a decrease in the useful life of distribution transformers. The decrease in the useful life of transformers causes high costs and shutdowns beyond the capacity of consumers and their dissatisfaction, which is a huge cos. It will have a lot for the power grid and the distribution company. Also, the temperature of the hot spot is one of the important and key parameters in determining the insulation life of distribution transformers, which depends on the temperature of the environment, oil and winding. In this paper, using Ansys Maxwell and COMSOL Multiphysics software, the life of transformers is estimated with the help of their lost life in the presence of harmonics of power distribution networks. Their lost life depends on the hot spot temperature of the transformer.
