Introduction to Power Transformers
Power transformers are crucial electrical devices in the power system. They are used to transfer electrical energy between different voltage levels, enabling efficient transmission and distribution of electricity over long distances. By stepping up the voltage at the generation side, power can be transmitted with lower current, reducing the power loss in the transmission lines. At the distribution end, the voltage is stepped down to a level suitable for industrial, commercial, and residential use. Power transformers play a vital role in ensuring the reliability and stability of the power grid.
