. 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
