Ganz - History

History

Before 1919, the company built ocean liners, dreadnought type battleships and submarines, power plants, automobiles and fighter aircraft.

The company was founded by Abraham Ganz in 1844. He established his own iron foundry in Buda. Consequently this factory played an important role in building the infrastructure of Hungarian Kingdom. At this time the agricultural machines, steam-locomotives, pumps and the railway carriages were the main products. At the beginning of the 20th century 60-80% of the factory's products were sold for export. On this base there has developed the firm-group which companies assist continuously the development of the Hungarian Machinery Industry.

At the end of the 19th century, the products of the Ganz and Partner Iron Mill and Machine Factory (hereinafter referred to as Ganz Works) promoted the expansion of alternating-current power transmissions.

In 1878, the company's general manager András Mechwart (1853–1942) founded the Department of Electrical Engineering headed by Károly Zipernowsky (1860–1939). Engineers Miksa Déri (1854–1938) and Ottó Bláthy (1860–1939) also worked at the department producing direct-current machines and arc lamps.

In cooperation, Zipernovsky, Déri and Bláthy constructed and patented the transformer (see Picture 2). The name "transformer" was created by Ottó Titusz Bláthy.

The transformer patents described two basic principles. Loads were to be connected in parallel, not in series as had been the general practice until 1885. Additionally, the inventors described the closed armature as an essential part of the transformer. Both factors assisted the stabilization of voltage under varying load, and allowed definition of standard voltages for distribution and loads. The parallel connection and efficient closed core made construction of electrical distribution systems technically and economically feasible.

It is noteworthy that the Ganz Works built the first transformers using iron cover of enameled mild iron wire, and started to use laminated core of today at the end of 1885.

Following introduction of transformer, the Ganz Works changed over to production of alternating-current equipment successfully. (For instance, Rome's electric supply was resolved by hydroelectric plant and energy transfer of long distance.)

The first specimen of the kilowatt-hour meter (electricity meter) produced on the basis of Hungarian Ottó Bláthy's patent and named after him was presented by the Ganz Works at the Frankfurt Fair in the autumn of 1889, and the first induction kilowatt-hour meter was already marketed by the factory at the end of the same year. These were the first alternating-current wattmeters, known by the name of Bláthy-meters.
