This blog provides a comprehensive overview of transformer development, starting with Michael Faraday’s experiments in electromagnetic induction in 1831 and progressing through key innovations like the ring-shaped transformer in 1885 by Hungarian engineers Bláthy, Déri, and Zipernowsky. It also touches on the first practical uses of transformers in electrical systems and the evolution of transformer design for efficiency, including the introduction of block-shaped transformers and dry transformers for safer, oil-free operations. The discourse spans the timeline until modern high-voltage power transformers, emphasizing continuous innovation in transformer technology.
