ABSTRACT
Transformers are efficient electrical machines that can convert 99.75% of the input power of the transformer to the output of the transformer. The manufacturing of electric transformers is done in different sizes ranging from thumb-sized transformers to very large sizes transformers weighing hundreds of tons and used in power grids. The transformer is used to change the value of the voltage in the Alternating Current power transmission system where the transformer cannot operate in direct current systems. The core’s installation of the transformer depends on the following factors: voltages, current, and frequency. The principle work of the electric transformer is based on Faraday’s law of electromagnetic induction. The ideal transformer is a theoretical assumption only and is used to understand the real transformer. Transformers carry ratings related to the primary and secondary windings. The ratings refer to the power in Kilo Volt Amper and primary/secondary voltages.
