Introduction to Power Transformers
A power transformer is a crucial device in the electrical power system. It operates on the principle of electromagnetic induction to transfer electrical energy between different voltage levels. Power transformers play a vital role in power generation, transmission, and distribution. They are used to step – up the voltage for long – distance power transmission to reduce energy losses and step – down the voltage for safe and efficient use in industrial and residential applications. The performance, reliability, and efficiency of power transformers directly impact the stability and quality of the entire power grid. Power Transformer
