As one of the big developing countries in Africa, Ethiopia has rich power resources and huge potential. In recent years, Ethiopia’s power industry has developed rapidly and made remarkable achievements.
Transformers can be divided into power transformers according to their use. Power transformers are mainly used in transmission and distribution lines to change the AC voltage to meet the needs of different users. Special transformers are used in special fields such as control, electric processing, electric drive, communication, automatic control and so on. Its main components are the primary coil, secondary coil and iron core (magnetic core). The main functions of the transformer are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulation (magnetic saturation transformer) and so on. Transformer is the basic equipment of transmission and distribution, widely used in industry, agriculture, transportation, urban communities and other fields.
