Power transformers are devices designed to transform electrical voltage from one level to another. These transformers are key components in electrical distribution networks, power plants, and industrial facilities. The main purpose of power transformers is either to increase or decrease voltage according to the requirements of a given application.
Voltage transformation in power transformers is carried out based on the principle of electromagnetic induction. The primary coil receives electrical current and creates a magnetic field, which is transferred to the secondary coil, where new voltage is induced. The ratio of the number of turns in the primary and secondary coil determines the resulting voltage. These transformers are constructed in various sizes and capacities to meet the diverse needs of electrical systems."
