On 1831 August 29, Faraday invented an "inductor ring, " known as the "Faraday induction coil, " which was in fact the world's first prototype transformer. But Faraday had only used it as a demonstration of electromagnetic induction, not as a practical application. Faraday induction coil Faraday induction coil in London in 1881, Lucien Kolar and John Dixon Gibbs demonstrated a device called a "secondary hand generator. " And sold the technology to Westinghouse, which may have been the first practical power transformer, but it wasn't the first. In 1884, Kolar and Dixon Gibbs demonstrated their equipment in the electrically lit city of Turin, Italy. Early transformers used linear cores, which were later replaced by more efficient ring cores. Westinghouse Engineers William Stanley built the first practical transformer in 1885, after buying patents for the transformer from George Westinghouse, Kolar, and John Johan Dixon Gibbs. The core of the transformer was later made up of e-type iron plates and was put into commercial use in 1886. The principle of transformer and transformer was first discovered by Faraday, but it did not come into practical use until the 1880s. The ability to use transformers for alternating current is one of the advantages in the competition between the direct and alternating current that a power plant should produce. Transformers can convert electrical energy into high-voltage, low-current forms, and then back again, thus greatly reducing the loss of electrical energy in the transmission process, making the economic transmission of electrical energy to achieve greater distance. That way, power plants could be built far away from electricity. Most of the world's electricity is finally delivered to consumers through a series of voltage changes.
