There are various types of transformer used in the electrical power system for different purposes, like generation, distribution, transmission and utilization of electrical power. The power transformer is one of them and it is very vital in the transmission process.The power transformers are used in the transmission networks of higher voltages. They are larger in size and are rated as follows 400 KV, 200 KV, 110 KV, 66 KV, 33 KV. They are mainly rated above 200 MVA. Power transformers are mainly …

Transformers are designed to grant the reliability, durability, and efficiency required in utility, industrial, and commercial applications. Transformers are important components in our current life and they make large power systems possible. To effectively transfer hundreds of megawatts of power over long distances, very high line voltages are required – in the range of 161 to 1000 kV. What is a TransformerA transformer is a passive electrical device designed to transfer alternating current (AC …
