Editing Marcel Deprez (section)

==Biography==
Deprez was born in [[Aillant-sur-Milleron]] in rural France and attended the School of Mines in Paris. He was not able to complete the course; however, he must have made a good impression, as he was employed as a secretary to the director of the school, [[Charles Combes]].<ref name=walters>[http://www.archivingindustry.com/Indicator/chaptereight.pdf The Engine Indicator] {{Webarchive|url=https://web.archive.org/web/20160304085636/http://www.archivingindustry.com/Indicator/chaptereight.pdf |date=2016-03-04 }}, John Walters, Chapter 8, p.8-20</ref>

At [[Creil]], from 1876 to 1886, Deprez conducted the first experiments to transmit [[electric power|electrical power]] over long distances. At the [[International Exposition of Electricity, Paris]], in 1881, Deprez undertook the task of presenting an [[electricity distribution]] system based on the long-distance transmission of [[direct current]]. The first successful attempt took place in 1882 from [[Miesbach]] to [[Munich]] at the occasion of the Exposition of Electricity in the Glaspalast organised by [[Oskar von Miller]]. There he transmitted 1.5&nbsp;kW at 2 kV over a distance of 35 miles.<ref name=arrillaga>{{cite book |page=1|url=https://books.google.com/books?id=I2mdgdflTQUC&pg=PA1|title=High Voltage Direct Current Transmission|isbn=978-0-85296-941-0|year=1998|publisher=Institution of Engineering and Technology (IET)|author=Jos Arrillaga|access-date=2009-01-06}}</ref>

Deprez conducted experiments in La Chapelle, Grenoble, Vizille, Paris, and Creil. He eventually attained [[Electric power transmission|transmission]] over thirty-five miles for industrial purposes. In 1889, [[René Thury]] continued his approach of arranging generators in series, eventually developing commercial systems delivering 20 megawatts at 125 kV over 230 kilometers.<ref name=arrillaga/>
