Investigating the working activities of transformers in urban electricity networks

Transformers act as the main element of electrical supply in the system and improve the efficiency of transformers in different parts of the network, including high, medium and low voltages, especially in 0.4 kV distribution networks have a good technical effect, if the issue of the transformer has a very important role in reducing the consumption of non-ferrous metals (copper and aluminum), which is extremely important in the economy of the subject and also in its reliability and is of particular importance.
