1885: Zipernowsky, Déry and Bláthy transformer

Károly Zipernowsky (born April 4, 1853 in Vienna , † November 29, 1942 in Budapest ) was a Hungarian electrical engineer and became known as one of the developers of the transformer .

biography

Zipernowsky was born in Vienna, but he graduated from high school in Pest, after which he worked in a pharmacy in Kecskemét. In 1872 he matriculated in Buda at the Royal József Technical University.

In his fourth year of study he was already teaching the young science of electrical engineering in the Association of Engineers and Builders. András Mechwart, managing director of the Ganz company, discovered him during one of his lectures . He hired the 25-year-old (1878) as head of the electrical engineering department.

Since Ganz was the first company in Hungary to deal with electricity, Zipernowsky's job was to develop power generation in Hungary. Within a few months, a new dynamo was built based on his plans. This groundbreaking direct current was produced for the company's own foundry. Under his leadership, Ganz became the pioneer of Hungarian AC technology .

From 1882, Miksa Déri also served the Ganz company, and together with Zipernowsky he applied for a patent for a self-excited alternating current generator. This generator supplied 1000 lightbulbs for the National Theater in Budapest with electricity. The theater was the third theater in the world to be equipped with electric light.

In 1883 a single-phase alternating current generator driven by a 150 hp steam engine was presented at the Vienna International Electrical Engineering Exhibition. This was a big leap forward in the development of the alternating current system, which caused a lot of attention. The machine was later used to illuminate the Keleti train station in Budapest.

He earned significant merits with the development of the transformer together with Miksa Déri and Ottó Titusz Bláthy in 1885, which first made the construction of electricity networks possible. An early application was the transmission of electricity from the Thorenberg power plant to the city of Lucerne in Switzerland .

This marked the beginning of the triumphal procession of the Ganz system, which he personally coordinated until 1893. His greatest success was the construction of the energy supply plant and the associated power lines for the city of Rome.

In 1893 Zipernowsky became professor of electrical engineering at the Technical and Economic University of Budapest (TUB) and corresponding member of the Hungarian Academy of Sciences .

In the 1906/07 school year he received his own lecture room and laboratory in the “FE” (Physics-Electrical Engineering) (today “F”) building, which he equipped with modern machines. His institute has overtaken all other European universities and test houses in the field of high voltage technology. You can still find the equipment in its original place.

From 1905 he was President of the Hungarian Electrotechnical Society.

In 1912 he donated 5000 korona (Hungarian currency) to the society in order to award their interest annually as a prize. He did not take part in the meeting from 1937, and his farewell letter was read out.
