Power transformers are electrical instruments used in transmitting electrical power from one circuit to another without changing the frequency. They operate by the principle ofelectromagnetic induction. They are used in transmitting electrical power between generators and distribution primary circuits.
A power transformer is a mere classification of transformers with a voltage range varying between 3 kv-400 kV and a ratin above 200 MVA. The voltaeratings of power transformers avalilable in the market indlude 400 kv, 200 y, 110 ky,66 ky, and 33 kv. The other types of transformers include distribution (230V-11kV) and instrument transformers.
Power transformers are essentialin minimizing substantial energy losses, due to joule's efect,in the transmission of large amounts of electrica power overong distances by converting it into high-voltape current then stepping it down to a safer low-voltape current. They are commonly found in power plants,industrial plants, and electric utility companies.
