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 voltage levels to facilitate efficient power transmission and distribution. By increasing the voltage for long - distance transmission, power losses are minimized, and then reducing the voltage to a safe and usable level for consumers. Power transformers come in various types, such as oil - immersed transformers, dry - type transformers, and auto - transformers, each with its own characteristics and application scenarios.
