Long-distance direct current transmission from Miesbach to Munich
The direct current transmission from Miesbach – Munich in Bavaria was the first transmission of electrical energy over a longer distance (57 km). It was put into operation in 1882 with a direct voltage of 2 kV , but failed after eight days due to a generator failure.

The line led from Miesbach via Holzkirchen and Sauerlach to Munich .
history
After the world's first international electricity exhibition had opened in Paris on August 10, 1881 , the later founder of the Deutsches Museum in Munich , Oskar von Miller , wanted to organize the Munich electricity exhibition , which opened on September 16, 1882 make the Parisian appear equal.
Therefore, together with the Frenchman Marcel Depréz, he had a high-voltage direct current transmission line built from Miesbach to Munich. In Miesbach, on the Knorrschacht site near the train station, a 1.5 HP dynamo was powered by a steam engine. The electrical energy generated in this way was transmitted at a voltage of 2 kV over a 57 km long telegraph line with a line resistance of around 3 kΩ to the Glaspalast in Munich , with an efficiency of 25%. Mainly a fountain was driven with the electrical energy .
Although the misused iron wire telegraph line was not designed for a current of half an ampere and failed after a few days, the concept of the overhead line was further developed in the following years. The three-phase transmission between Lauffen and Frankfurt was commercially successful in 1891.
A fountain was built in Miesbach on the 100th anniversary of the event in 1982.
