Kálmán Kandó

de Egerfarmos et Sztregova was born July 8, 1869, Pest, Hungary.

In 1894, Kálmán Kandó developed high-voltage three phase alternating current motors and generators for electric locomotives ; he is known as the father of the electric train. His work on railway electrification was done at the Ganz electric works in Budapest. He was the first who recognised that an electric train system can only be successful if it can use the electricity from public networks.
After his achievement in designing the three-phase motor and generator he moved to Italy. He would later return to Budapest to work at the Ganz factory where he became the managing director.

Kalman Kando

Shortly afterwards, Kando designed the three-phase motor and generator series. His interests soon guided him towards railway electrification, and he developed electrified railways operated by high-voltage alternating current. His most marvelous invention is the phase-changing electric locomotive, which was named Kando-locomotive after him.

This revolutionary invention transforms standard public utility (single-phase) current into three-phase alternating current in the locomotive and therefore makes it capable of hauling. The first electrified railway line in Europe, the Valtellina line in Italy, was completed on the basis of his designs. This line was the first in the world to be operated by high-voltage alternating current.

One of the sensations of the summer season in 1898 was a small electric train carrying the guests of a French lakeside hotel at Evian Les Bains to and from the close-by medicinal spring. The “S”-shaped track was merely 300 metres long, the train ran only at a speed of 10 km/hour, yet, its novel construction aroused great interest. The motor wagon was supplied by the Budapest-based Ganz Factory …

In 1923, the first electric locomotive with phase converter was constructed on the basis of Kando’s designs, and serial production began soon after. The section of the Hungarian State Railways between Budapest – Hegyeshalom – Vienna (1929) was built based on Kand&o’s invention. The Ganz Works achieved significant results in the development and production of the electric engine in the course of the last fifty years.

Electric history

SAfter the World War 1, in the frames of the Ganz Works, Kálmán Kandó constructed one-phase railway electric system of 16 kV and 50 Hz incipient all over the world. Its main attribute was the feed by normal network, so additional power station became unnecessary. Consequently, Hungarian electric traction could be formed according to the country’s energy management. Kálmán Kandó adapted the speed-torque curve to electric traction through changing the phase number and pole number. Kálmán Kandó built phase shifter in the locomotives forming speed levels.

Because of early death of Kálmán Kandó, László Verebély continued the work for the Hungarian Railways (MÁV). Moreover, he managed the construction of a nationwide power station (Bánhida) supplying as the railways as Budapest with electric power by transmission line of 110 kV. He elaborated the first plans of the nationwide cooperation of electric energy. In the 1930s he organized the Department of Electric Stations and Railways of the BMGE, so he became a professor of a significant branch of heavy current engineering …

Wiki: Ganz

The Ganz (Ganz vállalatok, “Ganz companies”) electric works in Budapest is probably best known for the manufacture of tramcars, but was also a pioneer in the application of three-phase alternating current to electric railways. Ganz also made / makes: ships (Ganz Danubius), bridge steel structures (Ganz Acélszerkezet), high voltage equipment (Ganz Transelektro). Notable engineers employed by Ganz in the field were Kálmán Kandó and Ottó Bláthy. The company is named after Ábrahám Ganz. In 2006, the power transmission and distribution sectors of Ganz Transelektro were acquired by Crompton Greaves, [1] but still doing business under the Ganz brand name, while the unit dealing with electric traction (propulsion and control systems for electric vehicles) was acquired by Škoda Holding and is now Ganz-Škoda Electric Ltd. …
