Emil Huber-Stockar
Emil Huber-Stockar (July 15, 1865 - May 9, 1939) was a Swiss entrepreneur and railway pioneer. He was an instrumental figure in the electrification of the Swiss railway network and worked as lead engineer and consultant for the Swiss Federal Railways. Life Huber was born on July 15, 1865 in Riesbach, Switzerland the son of Peter Emil and Anna Marie (née Werdmüller). His father hailed from a wealthy textile manufacturer family. His father was a former chairman of Oerlikon Buehrle and a pioneer of the machinery and electric industry. He had a prosper upbringing in Zurich District 7. After training as a mechanical engineer at the Swiss Federal Institute of Technology at Zurich (ETHZ) and spending some years in America, Huber took over the management of the Maschinenfabrik Oerlikon, founded by his father Peter Emil Huber-Werdmüller, near Zurich, Switzerland. He focussed on solving the difficulties of high power, electrically powered mainline railway systems. In 1904, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Max Huber (statesman)
Hans Max Huber (28 December 1874, in Zürich – 1 January 1960, in Zürich) was a Swiss lawyer and diplomat who represented Switzerland at a series of international conferences and institutions. He studied law at the Universities of Lausanne, Zurich and Berlin. Huber taught international, constitutional and canon law at the University of Zurich from 1902 to 1914, and retained this title until 1921 but could not teach due to World War I. During the War, he advised the Swiss Defence and Foreign Affairs ministries. From 1922 to 1939 he was a Judge of the Permanent Court of International Justice and he served as the Court's President from 1925 to 1927, and from 1928 to 1944 he was president of the International Committee of the Red Cross. He also acted as the arbitrator in the influential Island of Palmas Case between the United States and the Netherlands in 1928 at the Permanent Court of Arbitration The Permanent Court of Arbitration (PCA) is a non-UN intergovernmental organizati ...

15 KV AC Railway Electrification
Railway electrification systems using at are used on transport railways in Germany, Austria, Switzerland, Sweden, and Norway. The high voltage enables high power transmission with the lower frequency reducing the losses of the traction motors that were available at the beginning of the 20th century. Railway electrification in late 20th century tends to use AC systems which has become the preferred standard for new railway electrifications but extensions of the existing networks are not completely unlikely. In particular, the Gotthard Base Tunnel (opened on 1 June 2016) still uses 15 kV, 16.7 Hz electrification. Due to high conversion costs, it is unlikely that existing systems will be converted to despite the fact that this would reduce the weight of the on-board step-down transformers to one third that of the present devices. History The first electrified railways used series-wound DC motors, first at 600 V and then 1,500 V. Areas with 3 kV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utility Frequency
The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user. In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz. Current usage by country or region is given in the list of mains electricity by country. During the development of commercial electric power systems in the late-19th and early-20th centuries, many different frequencies (and voltages) had been used. Large investment in equipment at one frequency made standardization a slow process. However, as of the turn of the 21st century, places that now use the 50 Hz frequency tend to use 220–240 V, and those that now use 60 Hz tend to use 100–127 V. Both frequencies coexist today (Japan uses both) with no great technical reason to prefer one over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

Seebach-Wettingen Railway Electrification Trial
The Seebach-Wettingen railway electrification trial (1905-1909) was an important milestone in the development of electric railways. Maschinenfabrik Oerlikon (MFO) demonstrated the suitability of single-phase alternating current at high voltage for long-distance railway operation with the Seebach-Wettingen single-phase alternating current test facility. For this purpose, MFO electrified the 19.45-kilometre-long Swiss Federal Railways (SBB) route from Seebach to Wettingen at its own expense with single-phase alternating current at 15,000 volts. Overview By 1900, the use of direct current (DC), usually at 500-600 volts, to supply power to electric trams and trains was well-established. Examples include Trams in Budapest (from 1887) and the Liverpool Overhead Railway (opened 1893). This was satisfactory for urban systems but, for long distance railways, a higher voltage was desirable to reduce energy losses. The 106 km Valtellina line in Italy was electrified using three ...

Railway Electrification System
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a s ...

Maschinenfabrik Oerlikon
Maschinenfabrik Oerlikon was a Swiss engineering company based in the Zürich district of Oerlikon known for the early development of electric locomotives. It was founded in 1876 by the industrialist Peter Emil Huber-Werdmüller, and occupied a large site immediately to the west of Oerlikon railway station. In 1906 the armaments business was demerged to form ', which evolved into the technology company OC Oerlikon and the armaments company Rheinmetall Air Defence (formerly ''Oerlikon Contraves''). In 1967 Maschinenfabrik Oerlikon was taken over by Brown, Boveri & Cie, which in 1988 merged with ASEA to form ABB Group. The site of the company's works has been redeveloped, including the innovative public MFO-Park The MFO-Park is a public park in the Oerlikon quarter of the Swiss city of Zürich. The area to the north of Zürich Oerlikon railway station was once home to the extensive works of ''Maschinenfabrik Oerlikon'' (MFO), as site that has now been .... In the seco ...
