History of the Transformer and Electricity

Thales, a Greek scholar called the "father of science", is considered to be the first person to have experimented with electricity and magnetism.

In 1831 Michael Faraday discovered the principle of induction (Faraday's induction law) and did the first experiments with induction between coils of wire, including building a pair of coils on a toroidal closed magnetic core.

In 1878 Thomas Alva Edison an American inventor, founds the Edison Electric Light Co. in New York. In 2979, he presents his first incandescent light bulb, which stays lit for 45 hours.

In 1882 Edison Inaugurates the first "electric plants" (producing DC power), built in London and New York. The first DC electric power transmission line is constructed in Germany: 2400V, 59 km

In 1886 George Westinghouse, an American inventor and industrial entrepreneur, shows an interest in industrial electricity and founds the Westinghouse Electric Corporation. After having obtained a patent in 1887 for a transformer, he creates the first AC supply system for lighting in Buffalo, NY. He wins an installation contract, defeating Edison, for all electric infrastructure in the US. It's for this reason that AC distribution is imposed throughout the entire world today.

1924: Construction of the north-south 110 Kv overhead power line linking German coal-fired electric power plants locatedtnear the Rhine to hydro-electric plants in the Alps.

1967: The extra-high voltage networks (380 kV) of France, the Federal Republic of Germany and Switzerland are interconnected for the first time at the Laufenburg substation in Switzerland.
