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.
