STARTING OF THE ELECTRICAL POWER NETWORK 


During these decades use of electrical engineering increased dramatically.

 In 1882, Thomas Edison switched on the world's first large-scale electric power network that provided 110 volts — direct current (DC)
 supplied to 59 customers on Manhattan Island in New York City. In 1884,



Thomas Edison

 Sir Charles Parsons invented the steam turbine allowing for more efficient electric power generation. Alternating current, with its ability to transmit power more efficiently over long distances via the use of transformers,
 developed rapidly in the 1880's and 1890's with transformer designs by Károly Zipernowsky,
 Ottó Bláthy and Miksa Déri (later called ZBD transformers),
 Lucien Gaulard, John Dixon Gibbs and William Stanley, Jr.. Practical AC motor designs including induction motors were independently invented by Galileo Ferraris and Nikola Tesla and further developed into a practical three-phase form by Mikhail Dolivo-Dobrovolsky and Charles Eugene Lancelot Brown.Charles Steinmetz and Oliver Heaviside contributed to the theoretical basis of alternating current engineering. The spread in the use of AC set off in the United States what has been called the War of Currents between a George Westinghouse backed AC system and a Thomas Edison backed DC power system, with AC being adopted as the overall standard.
