Miesbach–Munich Power Transmission

The direct current transmission Mies Munich Bach was the first transfer of electric energy over a greater distance (57 km). It was taken in 1882 with a DC voltage of 2 kV in operation, but failed after a few days.

History

After the world's first International Electrical Exhibition was opened on August 10, 1881 in Paris, was the later founder of the Deutsches Museum in Munich, Oskar von Miller, an organizer of the Munich Elektricitäts exhibition, which opened on September 16, 1882, with this Paris can appear equal.

He, therefore, along with the Frenchman Marcel Deprez build a high-voltage direct current transmission by Mies Bach to Munich. In Mies Bach was powered by a steam engine, a 1.5 -horsepower dynamo. The electrical energy generated was transmitted over a 57 km long telegraph cable with a resistance of about 3 kOhm at a voltage of 2 kV to the Glass Palace in Munich, where the efficiency is 25 % higher. A fountain there was mainly driven by the electrical energy. The designed purpose of this telegraph line from poorly suitable iron wire was not designed for a current of half an ampere and failed after a few days.

In subsequent years, the concept was transferred to a 112 km long distance between the municipality Creil and Paris in France by Marcel Deprez. He increased the voltage to 5 kV to 6 kV and achieved an efficiency of 45%.

In Miesbach a fountain was built to mark the 100th anniversary of the event in 1982.

The three-phase transmission Lauffen -Frankfurt was a result in 1891 the first successful transmission of electrical energy by means of three-phase alternating current.
