Transformer: The Backbone of Electrical Power Systems In modern electrical power systems, the transformer plays a vital role in the generation, transmission, and distribution of electrical energy. Without transformers, it would be impossible to transmit electrical power efficiently over long distances. This blog explains the basic concept, working principle, construction, types, and applications of transformers in a simple and structured manner. What is a Transformer? A transformer is a static electrical device that transfers electrical energy from one circuit to another without changing the frequency , but by changing the voltage level . It works on the principle of mutual induction . Transformers are mainly used to: Step up voltage for transmission Step down voltage for distribution and utilization Working Principle of Transformer A transformer operates on the principle of Faraday’s Law of Electromagnetic Induction . When an alternating current (AC) flows t...
