A power transformer is one of the important types of transformers with several industrial and commercial applications. These devices comprise a power supply circuit which is further equipped with several electromagnetic components. These components initiate power transfer between different circuits. Driven on the principle of electromagnetic induction, these devices are used in applications where a large amount of voltage or electrical current transfer is required.
