The International Electrotechnical Exhibition took place in Frankfurt, Germany, presenting a pivotal moment in the advancement of electrical engineering. Central to this exhibition was the demonstration of the first long-distance transmission of high-power, three-phase electric current, which allowed for efficient power distribution over large distances. This innovation was essential as it illustrated the viability of alternating current systems, which were in direct competition with Thomas Edison’s direct current systems. Pioneers like Nikola Tesla had developed the three-phase system, allowing for more efficient electricity generation and transmission.

At the exhibition, visitors marvelled as electrical power was transmitted over a distance of several kilometers, illuminating a series of lamps powered by a distant generator. The remarkable feat not only captivated the audience but also showcased the potential of electric power to transform industries and everyday life. This successful demonstration played a critical role in shifting the global perspective towards the adoption of alternating current technology, which proved to be superior for long-distance transmission of electricity.

The exhibition served as a platform for engineers, inventors, and entrepreneurs, fostering discussions and exchanges of innovative ideas. It showcased the latest advancements in electrical machinery and technologies, leading to the burgeoning development of electrical infrastructure worldwide. The successful demonstration of high-power, three-phase electric current at the International Electrotechnical Exhibition was a milestone that heralded the onset of the electric age, fundamentally changing how electricity would be harnessed and utilized in the future.
