Alternating current systems are suitable for both lighting systems and the operation of motors and are therefore more suitable than direct current systems. The exhibition promotes public and private demand for the new energy of electricity.
It is Oskar von Miller who is responsible for the professional and technical management. He had previously operated the electrical systems of a cement works in Lauffen am Neckar with three-phase alternating current (three-phase current). It is therefore an obvious choice to transmit alternating current over a long distance from this cement works. The power source is a 220 kW generator. Thanks to the long-distance transmission of electricity, a sea of light bulbs shines in Frankfurt. The newspaper reads:
“Here the production of human goods stands before a That of epochal significance: a new period of human creativity receives its milestone through this power transmission.”
In 1977, AEG makes a name for itself again. This time with high-voltage direct current transmission (HVDC) over a distance of several thousand kilometers.
