Transformer development history
- Dec 07, 2017 -

Faraday on August 29, 1831 invented an "inductor ring", known as the "Faraday induction coil", is actually the world's first prototype of a transformer. However, Faraday only used it to demonstrate the principle of electromagnetic induction and did not consider it for practical purposes.

In 1881, Lucien Gaulard and John Dixon Gibbs demonstrated in London a device called a "secondary hand generator," and then put this technology Sold to Westinghouse, USA, which may be the first practical power transformer, but not the first one.

In 1884, Lusen Goola and John Dixon Gibbs exhibited their equipment in Turin, Italy, using electric lighting. Early transformers used a linear core, which was later replaced by a more effective annular core.

Westinghouse engineer William Stanley bought the transformer patent from George Westinghouse, Lussen Goral and John Dixon Gibbs in 1885, making the first practical transformer. Later, the core of the transformer by the E-type iron sheet stack formed, and in 1886 commercial use.

Transformer‘s principle was first discovered by Faraday, but it was not until the nineteen eighties began practical application. One of the advantages of using AC power transformers is that AC power plants should output DC and AC power. Transformers convert electrical energy to high-voltage, low-current form and then back again, thus greatly reducing the loss of electrical energy in the process of delivery, making the economic transport distance of electric energy farther. As a result, power plants can be built away from electricity. Most of the world's power after a series of transformation finally reached the user there.
