Introduction to Power Transformer
A power transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. It plays a crucial role in the power grid, stepping up or stepping down the voltage levels to ensure efficient and safe transmission and distribution of electricity. Power transformers are widely used in power generation plants, substations, industrial facilities, and residential areas. They are essential for converting high – voltage electricity from power plants into lower – voltage electricity suitable for end – users. Power Transformer
