Miesbach–Munich Power Transmission
Miesbach–Munich Power Transmission of 1882 was the first transmission of direct current (DC) electrical energy over a large distance (57 km). After the first International Exposition of Electricity was held in Paris in 1881, the German Empire set up a power transmission between a steam engine situated near Miesbach and the glass palace of Munich, where an electricity exhibition opened on September 16, 1882. The voltage used was 2000 V direct current, and the distance 57 kilometres. Only 2.5 kilowatts of power (about 1.25 Ampere) was transmitted, which was used to run an artificial waterfall . The system was designed by Oskar von Miller and Marcel Deprez. A simple iron telegraph wire was used, which failed a few days later. In later years, Deprez set up a 112 km long DC transmission in France between Creil and Paris, using 6 kV. On August 25, 1891, the Lauffen-Frankfurt Three Phase AC Transmission over 175 km became part of the International Electrotechnical Exhibition in Germany, setting an end to the war of the currents.
