A transformer is the simplest device that is used to transfer electrical energy from one alternating-current circuit to another circuit or multiple circuits, through the process of electromagnetic induction. A transformer works on the principle of electromagnetic induction to step up or step down the voltage. A transformer either increases AC voltage (Step-up transformer) or decreases AC voltage (Step-down transformer). A transformer, which is normally utilized in the transmission and ... You might have come across various types of transformers in your daily life either knowingly or unknowingly. This article illustrates various transformer types. There are different types of transformers based on the application, nature of use and number of phases. Based on the application, transformers are widely used in the electric power system to transmit the electric power between power plants, substations, industries and domestic customers. Before going into the types of transformers, Do you know how it is constructed? Do you know how a transformer works? Learn about the Construction And Working Principle Of Transformer. Learn about different types of electrical transformers, their designs, functions, and applications. Compare power transformers, toroidal transformers, autotransformers, induction regulators, polyphase transformers, and more.
