Types of Transformers “TRANSFORMER”- one of the oldest innovations in Electrical Engineering. A Transformer is an electrical device that can be used to transfer the power from one circuit and another circuit without physical contact and without changing its characteristics like frequency, phase. It is an essential device in every electrical network circuitry. It consists of majorly two circuits, namely primary circuits and one or more secondary circuits. Please refer to the link Everything You Need to Know About Transformers & Working of Transformers . In this discussion, we deal with different types of transformers. Working Principle of Transformer The transformer working depends upon Faraday’s electromagnetic induction law. The mutual induction phenomenon between two or more winding is responsible for power transformation. According to Faraday’s laws, “The Rate of change of flux linkage with respect to time is directly proportional to the EMF induced in a c...
