The Ganz Machinery Works Holding is a Hungarian holding company . Its products are related to rail transport, power generation, and water supply, among other industries.
151-678: The original Ganz Works or Ganz ( Hungarian : Ganz vállalatok or Ganz Művek , Ganz companies , formerly Ganz and Partner Iron Mill and Machine Factory ) operated between 1845 and 1949 in Budapest , Hungary. It was named after Ábrahám Ganz , the founder and manager of the company. Ganz 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 ships (through its Ganz Danubius division), bridge steel structures ( Ganz Acélszerkezet ) and high-voltage equipment ( Ganz Transelektro ). In
302-507: A cycle ). In certain applications, like guitar amplifiers , different waveforms are used, such as triangular waves or square waves . Audio and radio signals carried on electrical wires are also examples of alternating current. These types of alternating current carry information such as sound (audio) or images (video) sometimes carried by modulation of an AC carrier signal. These currents typically alternate at higher frequencies than those used in power transmission. Electrical energy
453-615: A Turkic language continued to be a matter of impassioned political controversy throughout the 18th and into the 19th centuries. During the latter half of the 19th century, a competing hypothesis proposed a Turkic affinity of Hungarian, or, alternatively, that both the Uralic and the Turkic families formed part of a superfamily of Ural–Altaic languages . Following an academic debate known as Az ugor-török háború ("the Ugric-Turkic war"),
604-403: A balanced signaling system, so that the two wires carry equal but opposite currents. Each wire in a twisted pair radiates a signal, but it is effectively cancelled by radiation from the other wire, resulting in almost no radiation loss. Coaxial cables are commonly used at audio frequencies and above for convenience. A coaxial cable has a conductive wire inside a conductive tube, separated by
755-417: A circumfix , to change a word's meaning and its grammatical function. Hungarian uses vowel harmony to attach suffixes to words. That means that most suffixes have two or three different forms, and the choice between them depends on the vowels of the head word. There are some minor and unpredictable exceptions to the rule. Nouns have 18 cases , which are formed regularly with suffixes. The nominative case
906-448: A dielectric layer. The current flowing on the surface of the inner conductor is equal and opposite to the current flowing on the inner surface of the outer tube. The electromagnetic field is thus completely contained within the tube, and (ideally) no energy is lost to radiation or coupling outside the tube. Coaxial cables have acceptably small losses for frequencies up to about 5 GHz. For microwave frequencies greater than 5 GHz,
1057-477: A power plant , energy is generated at a convenient voltage for the design of a generator , and then stepped up to a high voltage for transmission. Near the loads, the transmission voltage is stepped down to the voltages used by equipment. Consumer voltages vary somewhat depending on the country and size of load, but generally motors and lighting are built to use up to a few hundred volts between phases. The voltage delivered to equipment such as lighting and motor loads
1208-402: A wall socket . The abbreviations AC and DC are often used to mean simply Alternating Current and Direct Current , respectively, 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 (the full period is called
1359-440: A compromise between low frequency for traction and heavy induction motors, while still allowing incandescent lighting to operate (although with noticeable flicker). Most of the 25 Hz residential and commercial customers for Niagara Falls power were converted to 60 Hz by the late 1950s, although some 25 Hz industrial customers still existed as of the start of the 21st century. 16.7 Hz power (formerly 16 2/3 Hz)
1510-490: A direct current does not create electromagnetic waves. At very high frequencies, the current no longer flows in the wire, but effectively flows on the surface of the wire, within a thickness of a few skin depths . The skin depth is the thickness at which the current density is reduced by 63%. Even at relatively low frequencies used for power transmission (50 Hz – 60 Hz), non-uniform distribution of current still occurs in sufficiently thick conductors . For example,
1661-437: A form of dielectric waveguides, can be used. For such frequencies, the concepts of voltages and currents are no longer used. Alternating currents are accompanied (or caused) by alternating voltages. An AC voltage v can be described mathematically as a function of time by the following equation: where The peak-to-peak value of an AC voltage is defined as the difference between its positive peak and its negative peak. Since

#17327694062261812-707: A high proportion of words specific to agriculture and livestock are of Chuvash origin. A strong Chuvash influence was also apparent in Hungarian burial customs. The first written accounts of Hungarian date to the 10th century, such as mostly Hungarian personal names and place names in De Administrando Imperio , written in Greek by Eastern Roman Emperor Constantine VII . No significant texts written in Old Hungarian script have survived, because
1963-459: A higher voltage requires less loss-producing current than for the same power at a lower voltage. Power is often transmitted at hundreds of kilovolts on pylons , and transformed down to tens of kilovolts to be transmitted on lower level lines, and finally transformed down to 100 V – 240 V for domestic use. High voltages have disadvantages, such as the increased insulation required, and generally increased difficulty in their safe handling. In
2114-957: A lighting system where sets of induction coils were installed along a high voltage AC line. Instead of changing voltage, the primary windings transferred power to the secondary windings which were connected to one or several 'electric candles' (arc lamps) of his own design, used to keep the failure of one lamp from disabling the entire circuit. In 1878, the Ganz factory , Budapest, Hungary, began manufacturing equipment for electric lighting and, by 1883, had installed over fifty systems in Austria-Hungary . Their AC systems used arc and incandescent lamps, generators, and other equipment. Alternating current systems can use transformers to change voltage from low to high level and back, allowing generation and consumption at low voltages but transmission, possibly over great distances, at high voltage, with savings in
2265-399: A millennium. These include tehén 'cow' (cf. Avestan daénu ); tíz 'ten' (cf. Avestan dasa ); tej 'milk' (cf. Persian dáje 'wet nurse'); and nád 'reed' (from late Middle Iranian ; cf. Middle Persian nāy and Modern Persian ney ). Archaeological evidence from present-day southern Bashkortostan confirms the existence of Hungarian settlements between
2416-812: A million additional people scattered in other parts of the world. For example, there are more than one hundred thousand Hungarian speakers in the Hungarian American community and 1.5 million with Hungarian ancestry in the United States . Hungarian is the official language of Hungary, and thus an official language of the European Union. Hungarian is also one of the official languages of Serbian province of Vojvodina and an official language of three municipalities in Slovenia : Hodoš , Dobrovnik and Lendava , along with Slovene . Hungarian
2567-989: A number of railcars for the Hungarian State Railways together with units with de Dion-Bouton boilers, Ganz steam motors and equipments, and Raba carriages built by the Raba Hungarian Wagon and Machine Factory in Győr . In 1908, the Borzsavölgyi Gazdasági Vasút (BGV), a narrow-gauge railway in Carpathian Ruthenia (today's Ukraine), purchased five railcars from Ganz and four railcars from the Hungarian Royal State Railway Machine Factory with de Dion-Bouton boilers. The Ganz company started to export steam motor railcars to
2718-406: A process of nyelvújítás ( language revitalization ). Some words were shortened ( győzedelem > győzelem , 'victory' or 'triumph'); a number of dialectal words spread nationally ( e.g. , cselleng 'dawdle'); extinct words were reintroduced ( dísz , 'décor'); a wide range of expressions were coined using the various derivative suffixes; and some other, less frequently used methods of expanding
2869-1069: A similarly dramatic way over these three centuries. After the arrival of the Hungarians in the Carpathian Basin , the language came into contact with a variety of speech communities , among them Slavic , Turkic , and German . Turkic loans from this period come mainly from the Pechenegs and Cumanians , who settled in Hungary during the 12th and 13th centuries: e.g. koboz " cobza " (cf. Turkish kopuz 'lute'); komondor "mop dog" (< * kumandur < Cuman ). Hungarian borrowed 20% of words from neighbouring Slavic languages : e.g. tégla 'brick'; mák 'poppy seed'; szerda 'Wednesday'; csütörtök 'Thursday'...; karácsony 'Christmas'. These languages in turn borrowed words from Hungarian: e.g. Serbo-Croatian ašov from Hungarian ásó 'spade'. About 1.6 percent of
3020-522: A single center-tapped transformer giving two live conductors, is a common distribution scheme for residential and small commercial buildings in North America. This arrangement is sometimes incorrectly referred to as "two phase". A similar method is used for a different reason on construction sites in the UK. Small power tools and lighting are supposed to be supplied by a local center-tapped transformer with
3171-571: A solid technological superiority and revolutionized the world's milling industry. Budapest's milling industry grow the second largest in the world, behind the American Minneapolis. The Hungarian grain export increased by 66% within some years. In 1878, the company's general manager András Mechwart founded the Department of Electrical Engineering headed by Károly Zipernowsky . Engineers Miksa Déri and Ottó Bláthy also worked at
SECTION 20
#17327694062263322-502: A stable output voltage, regardless of the actual load. In cooperation, Zipernovsky, Bláthy and Déri (known as the ZBD team) constructed and patented the transformer . The "transformer" was named by Ottó Titusz Bláthy. The three invented the first high efficiency, closed core shunt connection transformer. They also invented the modern power distribution system : Instead of a series of connections they connected supply transformers in parallel to
3473-555: A voltage of 55 V between each power conductor and earth. This significantly reduces the risk of electric shock in the event that one of the live conductors becomes exposed through an equipment fault whilst still allowing a reasonable voltage of 110 V between the two conductors for running the tools. A third wire , called the bond (or earth) wire, is often connected between non-current-carrying metal enclosures and earth ground. This conductor provides protection from electric shock due to accidental contact of circuit conductors with
3624-403: A wire that is made of a non-perfect conductor (a conductor with finite, rather than infinite, electrical conductivity) pushes the alternating current, along with their associated electromagnetic fields, away from the wire's center. The phenomenon of alternating current being pushed away from the center of the conductor is called skin effect , and a direct current does not exhibit this effect, since
3775-470: Is 230 × R × W × 2 {\displaystyle 230\times R\times W\times 2} , that is 460 RW. During the course of one cycle (two cycle as the power) the voltage rises from zero to 325 V, the power from zero to 460 RW, and both falls through zero. Next, the voltage descends to reverse direction, -325 V, but the power ascends again to 460 RW, and both returns to zero. Alternating current
3926-400: Is subject–verb–object (SVO). However, Hungarian is a topic-prominent language , and so has a word order that depends not only on syntax but also on the topic–comment structure of the sentence (for example, what aspect is assumed to be known and what is emphasized). A Hungarian sentence generally has the following order: topic, comment (or focus), verb and the rest. The topic shows that
4077-589: Is always on the first syllable of a word, as in Finnish and the neighbouring Slovak and Czech . There is a secondary stress on other syllables in compounds: viszontlátásra ("goodbye") is pronounced /ˈvisontˌlaːtaːʃrɒ/ . Elongated vowels in non-initial syllables may seem to be stressed to an English-speaker, as length and stress correlate in English. Hungarian is an agglutinative language . It uses various affixes , mainly suffixes but also some prefixes and
4228-515: Is an electric current that periodically reverses direction and changes its magnitude continuously with time ranging between some maximum and minimum values, in contrast to direct current (DC), which flows only in one direction. Alternating current is the type of electric current through which electric power is delivered to businesses and residences, and it is the type of electric current that consumers typically use when they plug kitchen appliances , televisions , fans and electric lamps into
4379-530: Is called Litz wire . This measure helps to partially mitigate skin effect by forcing more equal current throughout the total cross section of the stranded conductors. Litz wire is used for making high-Q inductors , reducing losses in flexible conductors carrying very high currents at lower frequencies, and in the windings of devices carrying higher radio frequency current (up to hundreds of kilohertz), such as switch-mode power supplies and radio frequency transformers . As written above, an alternating current
4530-505: Is distributed as alternating current because AC voltage may be increased or decreased with a transformer . This allows the power to be transmitted through power lines efficiently at high voltage , which reduces the energy lost as heat due to resistance of the wire, and transformed to a lower, safer voltage for use. Use of a higher voltage leads to significantly more efficient transmission of power. The power losses ( P w {\displaystyle P_{\rm {w}}} ) in
4681-439: Is double of the one of the voltage's. To illustrate these concepts, consider a 230 V AC mains supply used in many countries around the world. It is so called because its root mean square value is 230 V. This means that the time-averaged power delivered P average {\displaystyle P_{\text{average}}} is equivalent to the power delivered by a DC voltage of 230 V. To determine

4832-549: Is expressed by a possessive suffix on the possessed object, rather than the possessor as in English (Peter's apple becomes Péter almája , literally 'Peter apple-his'). Noun plurals are formed with –k ( az almák 'the apples'), but after a numeral, the singular is used ( két alma 'two apples', literally 'two apple'; not *két almák ). Unlike English, Hungarian uses case suffixes and nearly always postpositions instead of prepositions. There are two types of articles in Hungarian, definite and indefinite, which roughly correspond to
4983-479: Is linked to Donát Bánki and János Csonka but it is not clear that they ever worked for Ganz. Ganz produced engines whose designs were licensed to Western European partners, notably in the United Kingdom and Italy. The Ganz Company started to construct steam locomotives and steam railcars from the 1860s. Between 1901 and 1908, Ganz Works of Budapest and de Dion-Bouton of Paris collaborated to build
5134-469: Is made of electric charge under periodic acceleration , which causes radiation of electromagnetic waves . Energy that is radiated is lost. Depending on the frequency, different techniques are used to minimize the loss due to radiation. At frequencies up to about 1 GHz, pairs of wires are twisted together in a cable, forming a twisted pair . This reduces losses from electromagnetic radiation and inductive coupling . A twisted pair must be used with
5285-442: Is marked with boldface. Hungarian has a four-tiered system for expressing levels of politeness. From highest to lowest: The four-tiered system has somewhat been eroded due to the recent expansion of " tegeződés " and " önözés ". Some anomalies emerged with the arrival of multinational companies who have addressed their customers in the te (least polite) form right from the beginning of their presence in Hungary. A typical example
5436-589: Is now frequently questioned. The name of Hungary could be a result of regular sound changes of Ungrian/Ugrian , and the fact that the Eastern Slavs referred to Hungarians as Ǫgry/Ǫgrove (sg. Ǫgrinŭ ) seemed to confirm that. Current literature favors the hypothesis that it comes from the name of the Turkic tribe Onoğur (which means ' ten arrows ' or ' ten tribes ' ). There are numerous regular sound correspondences between Hungarian and
5587-623: Is officially recognized as a minority or regional language in Austria , Croatia , Romania , Zakarpattia in Ukraine , and Slovakia . In Romania it is a recognized minority language used at local level in communes, towns and municipalities with an ethnic Hungarian population of over 20%. The dialects of Hungarian identified by Ethnologue are: Alföld, West Danube, Danube-Tisza, King's Pass Hungarian, Northeast Hungarian, Northwest Hungarian, Székely and West Hungarian. These dialects are, for
5738-521: Is probably by Guillaume Duchenne , inventor and developer of electrotherapy . In 1855, he announced that AC was superior to direct current for electrotherapeutic triggering of muscle contractions. Alternating current technology was developed further by the Hungarian Ganz Works company (1870s), and in the 1880s: Sebastian Ziani de Ferranti , Lucien Gaulard , and Galileo Ferraris . In 1876, Russian engineer Pavel Yablochkov invented
5889-399: Is sometimes described as having free word order, different word orders are generally not interchangeable, and the neutral order is not always correct to use. The intonation is also different with different topic-comment structures. The topic usually has a rising intonation, the focus having a falling intonation. In the following examples, the topic is marked with italics, and the focus (comment)
6040-446: Is standardized, with an allowable range of voltage over which equipment is expected to operate. Standard power utilization voltages and percentage tolerance vary in the different mains power systems found in the world. High-voltage direct-current (HVDC) electric power transmission systems have become more viable as technology has provided efficient means of changing the voltage of DC power. Transmission with high voltage direct current
6191-514: Is still used in some European rail systems, such as in Austria , Germany , Norway , Sweden and Switzerland . Off-shore, military, textile industry, marine, aircraft, and spacecraft applications sometimes use 400 Hz, for benefits of reduced weight of apparatus or higher motor speeds. Computer mainframe systems were often powered by 400 Hz or 415 Hz for benefits of ripple reduction while using smaller internal AC to DC conversion units. A direct current flows uniformly throughout

6342-482: Is the Funeral Sermon and Prayer , which dates to the 1190s. Although the orthography of these early texts differed considerably from that used today, contemporary Hungarians can still understand a great deal of the reconstructed spoken language, despite changes in grammar and vocabulary. A more extensive body of Hungarian literature arose after 1300. The earliest known example of Hungarian religious poetry
6493-700: Is the 14th-century Lamentations of Mary . The first Bible translation was the Hussite Bible in the 1430s. The standard language lost its diphthongs , and several postpositions transformed into suffixes , including reá "onto" (the phrase utu rea "onto the way" found in the 1055 text would later become út ra ). There were also changes in the system of vowel harmony . At one time, Hungarian used six verb tenses , while today only two or three are used. In 1533, Kraków printer Benedek Komjáti published Letters of St. Paul in Hungarian (modern orthography: A Szent Pál levelei magyar nyelven ),
6644-532: Is the Swedish furniture shop IKEA , whose web site and other publications address the customers in te form. When a news site asked IKEA—using the te form—why they address their customers this way, IKEA's PR Manager explained in his answer—using the ön form—that their way of communication reflects IKEA's open-mindedness and the Swedish culture. However IKEA in France uses the polite ( vous ) form. Another example
6795-485: Is the communication of Yettel Hungary (earlier Telenor, a mobile network operator) towards its customers. Yettel chose to communicate towards business customers in the polite ön form while all other customers are addressed in the less polite te form. During the first early phase of Hungarian language reforms (late 18th and early 19th centuries) more than ten thousand words were coined, several thousand of which are still actively used today (see also Ferenc Kazinczy ,

The RMS voltage is the square root of the mean over one cycle of the square of the instantaneous voltage. The relationship between voltage and
7097-407: Is unmarked ( az alma 'the apple') and, for example, the accusative is marked with the suffix –t ( az almát '[I eat] the apple'). Half of the cases express a combination of the source-location-target and surface-inside-proximity ternary distinctions (three times three cases); there is a separate case ending – ból / –ből meaning a combination of source and insideness: 'from inside of'. Possession
7248-425: Is used to transmit information , as in the cases of telephone and cable television . Information signals are carried over a wide range of AC frequencies. POTS telephone signals have a frequency of about 3 kHz, close to the baseband audio frequency. Cable television and other cable-transmitted information currents may alternate at frequencies of tens to thousands of megahertz. These frequencies are similar to

The Ganz Shipyard experienced its most productive times during the four decades following nationalisation. In the course of this period 1100 ship units were produced, the number of completed seagoing ships was 240 and that of floating cranes was 663. As a result of the great economic and social crises of

#17327694062267852-684: The Romanian lexicon is of Hungarian origin. In the 21st century, studies support an origin of the Uralic languages, including early Hungarian, in eastern or central Siberia , somewhere between the Ob and Yenisei rivers or near the Sayan mountains in the Russian – Mongolian border region. A 2019 study based on genetics, archaeology and linguistics, found that early Uralic speakers arrived in Europe from

Linguistic connections between Hungarian and other Uralic languages were noticed in the 1670s, and the family itself was established in 1717. Hungarian has traditionally been assigned to the Ugric branch along with
8154-845: The Volga River and the Ural Mountains . The Onoğurs (and Bulgars ) later had a great influence on the language, especially between the 5th and 9th centuries. This layer of Turkic loans is large and varied (e.g. szó ' word ' , from Turkic ; and daru ' crane ' , from the related Permic languages ), and includes words borrowed from Oghur Turkic ; e.g. borjú ' calf ' (cf. Chuvash păru , părăv vs. Turkish buzağı ); dél 'noon; south' (cf. Chuvash tĕl vs. Turkish dial. düš ). Many words related to agriculture, state administration and even family relationships show evidence of such backgrounds. Hungarian syntax and grammar were not influenced in

The new firm became active in developing alternating current (AC) electric infrastructure throughout the United States. The Edison Electric Light Company held an option on the US rights for the Ganz ZBD transformers, requiring Westinghouse to pursue alternative designs on the same principles. George Westinghouse had bought Gaulard and Gibbs' patents for $ 50,000 in February 1886. He assigned to William Stanley
8456-565: The rotary phase converter , enabling electric locomotives to use three-phase motors whilst supplied via a single overhead wire, carrying the simple industrial frequency (50 Hz) single phase AC of the high-voltage national networks. After World War I , at the Ganz Works, Kálmán Kandó constructed a single-phase electric railway system using 16 kV at 50 Hz. A similar system, but using 15 kV at 16.7 Hz , later became widely used in Europe. The main attribute of Kandó's 50 Hz system

From 1911, the unified company adopted the "Ganz–Danubius " brand name. In the beginning of the 20th century the company had 19 shipyards on the Danube and the Adriatic Sea in the city of Rijeka and Pula. As Ganz Danubius, the company became involved in shipbuilding before, and during, World War I . Ganz

10872-456: The beginning of the 20th century, 60 to 80% of the factory's products were sold for export. After the death of Abraham Ganz, the heirs entrusted the management of the factory to his direct colleagues at Ganz Művek: Antal Eichleter, Ulrik Keller and Andreas Mechwart, which then took the name Ganz & Co. The Ganz family sold the company, which consisted of five departments, and in April 1869 it
11023-413: The biggest difference being that waveguides have no inner conductor. Waveguides can have any arbitrary cross section, but rectangular cross sections are the most common. Because waveguides do not have an inner conductor to carry a return current, waveguides cannot deliver energy by means of an electric current , but rather by means of a guided electromagnetic field . Although surface currents do flow on
11174-677: The casting master at the Roller Mill Plant (referred to as Hengermalom in Hungarian). In 1854 he began manufacturing hard cast railroad wheels in his own plant founded in 1844. The management of the steam mill paid a share of the profit to Ganz. This enabled him to buy, in 1844, land and a house for 4500 Forints in Víziváros, Buda castle district. Abraham Ganz built his own foundry on this site and started to work there with seven assistants. They made mostly casting products for
11325-548: The charge.[3] Ganz recognized that, to develop his factory, he had to make products that were mass-produced. In 1846 the Pest-Vác railway line was built. At that time, European foundries made wrought iron rims for spoked wagon wheels by pouring the casts in shapes in sand, and leaving them to cool down. He successfully developed a railway wheel casting technology; it was the new method of "crust-casting" to produce cheap yet sturdy iron railway wheels, which greatly contributed to
11476-547: The city of Pomona, California , which was 14 miles away. Meanwhile, the possibility of transferring electrical power from a waterfall at a distance was explored at the Grängesberg mine in Sweden. A 45 m fall at Hällsjön, Smedjebackens kommun, where a small iron work had been located, was selected. In 1893, a three-phase 9.5 kv system was used to transfer 400 horsepower a distance of 15 km , becoming
11627-514: The company made many types of Albatros and Fokker fighter planes. Before 1919, the company built ocean liners , dreadnought type battleships and submarines , power plants , automobiles and many types of fighter aircraft. The world's first turboprop engine was the Jendrassik Cs-1 designed by the Hungarian mechanical engineer György Jendrassik . It was built and tested in the Ganz factory in Budapest between 1939 and 1942. It
11778-554: The company's shares and consequently the railway vehicle factory is now a member of the international railway vehicle manufacturing group, Jenbacher Transport Systeme. At present, the Ganz Electric Works, under the name of Ganz-Ansaldo is a member of the Italian industrial giant, AnsaldoBreda . The Ganz Works were transformed into holdings. Ganz-Danubius was wound up in 1994. The Ganz Electric Meter Factory in Gödöllő became
11929-507: The cost of conductors and energy losses. A bipolar open-core power transformer developed by Lucien Gaulard and John Dixon Gibbs was demonstrated in London in 1881, and attracted the interest of Westinghouse . They also exhibited the invention in Turin in 1884. However, these early induction coils with open magnetic circuits are inefficient at transferring power to loads . Until about 1880,
12080-514: The cross-section of a homogeneous electrically conducting wire. An alternating current of any frequency is forced away from the wire's center, toward its outer surface. This is because an alternating current (which is the result of the acceleration of electric charge ) creates electromagnetic waves (a phenomenon known as electromagnetic radiation ). Electric conductors are not conducive to electromagnetic waves (a perfect electric conductor prohibits all electromagnetic waves within its boundary), so
12231-411: The cross-sectional area. A conductor's AC resistance is higher than its DC resistance, causing a higher energy loss due to ohmic heating (also called I R loss). For low to medium frequencies, conductors can be divided into stranded wires, each insulated from the others, with the relative positions of individual strands specially arranged within the conductor bundle. Wire constructed using this technique
12382-473: The department producing direct-current machines and arc lamps . In 1878, the company began producing equipment for electric lighting and, by 1883, had installed over fifty systems in Austria-Hungary. Their AC systems used arc and incandescent lamps, generators, and other equipment. The first turbo generators were water turbines which drove electric generators . The first Hungarian water turbine
12533-476: The design of electric motors, particularly for hoisting, crushing and rolling applications, and commutator-type traction motors for applications such as railways . However, low frequency also causes noticeable flicker in arc lamps and incandescent light bulbs . The use of lower frequencies also provided the advantage of lower transmission losses, which are proportional to frequency. The original Niagara Falls generators were built to produce 25 Hz power, as
12684-589: The early 20th century the company experienced its heyday and became the third-largest industrial enterprise in the Kingdom of Hungary after the Manfréd Weiss Steel and Metal Works and the MÁVAG company. Since 1989, various parts of Ganz have been taken over by other companies. The company was founded by Ábrahám Ganz in 1844. He was invited to Pest, Hungary , by Count István Széchenyi and became
12835-465: The east, specifically from eastern Siberia. Hungarian historian and archaeologist Gyula László claims that geological data from pollen analysis seems to contradict the placing of the ancient Hungarian homeland near the Urals. Today, the consensus among linguists is that Hungarian is a member of the Uralic family of languages. The classification of Hungarian as a Uralic/Finno-Ugric rather than
12986-508: The electrical system to a safe state. All bond wires are bonded to ground at the main service panel, as is the neutral/identified conductor if present. The frequency of the electrical system varies by country and sometimes within a country; most electric power is generated at either 50 or 60 Hertz . Some countries have a mixture of 50 Hz and 60 Hz supplies, notably electricity power transmission in Japan . A low frequency eases
13137-522: The electromagnetic wave frequencies often used to transmit the same types of information over the air . The first alternator to produce alternating current was an electric generator based on Michael Faraday 's principles constructed by the French instrument maker Hippolyte Pixii in 1832. Pixii later added a commutator to his device to produce the (then) more commonly used direct current. The earliest recorded practical application of alternating current
13288-630: The equivalents in English. Adjectives precede nouns ( a piros alma 'the red apple') and have three degrees: positive ( piros 'red'), comparative ( pirosabb 'redder') and superlative ( a legpirosabb 'the reddest'). If the noun takes the plural or a case, an attributive adjective is invariable: a piros almák 'the red apples'. However, a predicative adjective agrees with the noun: az almák piros ak 'the apples are red'. Adjectives by themselves can behave as nouns (and so can take case suffixes): Melyik almát kéred? – A piros at . 'Which apple would you like? – The red one'. The neutral word order
13439-433: The exception of one standard and one metre gauge trainset. In 1982/83 Ganz-Mávag supplied an order for electric multiple units to New Zealand Railways Corporation for Wellington suburban services. The order was made in 1979, and was for 44 powered units and 44 trailer units, see New Zealand EM class electric multiple unit . Ganz-MÁVAG delivered 29 trams (2 car sets) to Alexandria, Egypt from 1985 to 1986. In 1911,
13590-414: The experiments; In their joint 1885 patent applications for novel transformers (later called ZBD transformers), they described two designs with closed magnetic circuits where copper windings were either wound around a ring core of iron wires or else surrounded by a core of iron wires. In both designs, the magnetic flux linking the primary and secondary windings traveled almost entirely within the confines of
13741-419: The first Hungarian-language book set in movable type . By the 17th century, the language already closely resembled its present-day form, although two of the past tenses remained in use. German, Italian and French loans also began to appear. Further Turkish words were borrowed during the period of Ottoman rule (1541 to 1699). In the 19th century, a group of writers, most notably Ferenc Kazinczy , spearheaded
13892-479: The first commercial application. In 1893, Westinghouse built an alternating current system for the Chicago World Exposition . In 1893, Decker designed the first American commercial three-phase power plant using alternating current—the hydroelectric Mill Creek No. 1 Hydroelectric Plant near Redlands, California . Decker's design incorporated 10 kV three-phase transmission and established
14043-408: The first transformers using iron plating of enamelled mild iron wire, and started to use laminated cores to eliminate eddy currents In 1886, the ZBD engineers designed, and the company supplied, electrical equipment for the world's first power station to use AC generators to power a parallel connected common electrical network. This was the Italian steam-powered Rome-Cerchi power plant. Following
14194-564: The inner walls of the waveguides, those surface currents do not carry power. Power is carried by the guided electromagnetic fields. The surface currents are set up by the guided electromagnetic fields and have the effect of keeping the fields inside the waveguide and preventing leakage of the fields to the space outside the waveguide. Waveguides have dimensions comparable to the wavelength of the alternating current to be transmitted, so they are feasible only at microwave frequencies. In addition to this mechanical feasibility, electrical resistance of
14345-469: The introduction of the transformer, the Ganz Works changed over to production of alternating-current equipment. For instance, Rome's electricity was supplied by hydroelectric plant and long-distance energy transfer. The first mass-produced kilowatt-hour meter ( electricity meter ), based on Hungarian Ottó Bláthy 's patent and named after him, was presented by the Ganz Works at the Frankfurt Fair in
14496-511: The iron core, with no intentional path through air (see toroidal cores ). The new transformers were 3.4 times more efficient than the open-core bipolar devices of Gaulard and Gibbs. The Ganz factory in 1884 shipped the world's first five high-efficiency AC transformers. This first unit had been manufactured to the following specifications: 1,400 W, 40 Hz, 120:72 V, 11.6:19.4 A, ratio 1.67:1, one-phase, shell form. The ZBD patents included two other major interrelated innovations: one concerning
14647-482: The language holds official status nationally in Hungary and regionally in Romania , Slovakia , Serbia , Austria and Slovenia . In 2014 The proportion of Transylvanian students studying Hungarian exceeded the proportion of Hungarian students, which shows that the effects of Romanianization are slowly getting reversed and regaining popularity. The Dictate of Trianon resulted in a high proportion of Hungarians in
14798-436: The language were utilized. This movement produced more than ten thousand words, most of which are used actively today. The 19th and 20th centuries saw further standardization of the language, and differences between mutually comprehensible dialects gradually diminished. In 1920, Hungary signed the Treaty of Trianon , losing 71 percent of its territory and one-third of the ethnic Hungarian population along with it. Today,
14949-489: The leading figure of the Hungarian language reforms.) Kazinczy's chief goal was to replace existing words of German and Latin origins with newly created Hungarian words. As a result, Kazinczy and his later followers (the reformers) significantly reduced the formerly high ratio of words of Latin and German origins in the Hungarian language, which were related to social sciences, natural sciences, politics and economics, institutional names, fashion etc. Giving an accurate estimate for
15100-464: The limitations of the direct current system. In 1886, the ZBD engineers designed the world's first power station that used AC generators to power a parallel-connected common electrical network, the steam-powered Rome-Cerchi power plant. The reliability of the AC technology received impetus after the Ganz Works electrified a large European metropolis: Rome in 1886. Building on the advancement of AC technology in Europe, George Westinghouse founded
15251-473: The locomotive and wagon Works were merged under the name of Railway Vehicle Factory and then the machine construction branch went through significant development. The production of industrial and apartment house lifts became a new branch. Ganz-MÁVAG took over a lot of smaller plants in the 1960s and 1970s and their product range was extended. Among other things, they increased their bridge-building capacity. They made iron structures for several Tisza bridges, for
15402-429: The losses (due mainly to the dielectric separating the inner and outer tubes being a non-ideal insulator) become too large, making waveguides a more efficient medium for transmitting energy. Coaxial cables often use a perforated dielectric layer to separate the inner and outer conductors in order to minimize the power dissipated by the dielectric. Waveguides are similar to coaxial cables, as both consist of tubes, with
15553-419: The lower speed is preferable for larger machines. If the load on a three-phase system is balanced equally among the phases, no current flows through the neutral point . Even in the worst-case unbalanced (linear) load, the neutral current will not exceed the highest of the phase currents. Non-linear loads (e.g. the switch-mode power supplies widely used) may require an oversized neutral bus and neutral conductor in
15704-578: The main line. 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 stabilisation 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. The Ganz Works built
15855-484: The main street of Great Barrington. The spread of Westinghouse and other AC systems triggered a push back in late 1887 by Thomas Edison (a proponent of direct current), who attempted to discredit alternating current as too dangerous in a public campaign called the " war of the currents ". In 1888, alternating current systems gained further viability with introduction of a functional AC motor , something these systems had lacked up till then. The design, an induction motor ,
16006-538: The maximum value of sin ( x ) {\displaystyle \sin(x)} is +1 and the minimum value is −1, an AC voltage swings between + V peak {\displaystyle +V_{\text{peak}}} and − V peak {\displaystyle -V_{\text{peak}}} . The peak-to-peak voltage, usually written as V pp {\displaystyle V_{\text{pp}}} or V P-P {\displaystyle V_{\text{P-P}}} ,
16157-448: The medium of writing used at the time, wood, is perishable. The Kingdom of Hungary was founded in 1000 by Stephen I . The country became a Western -styled Christian ( Roman Catholic ) state, with Latin script replacing Hungarian runes . The earliest remaining fragments of the language are found in the establishing charter of the abbey of Tihany from 1055, intermingled with Latin text. The first extant text fully written in Hungarian
16308-405: The member of the international Schlumberger group. In 2006, the power transmission and distribution sectors of Ganz Transelektro were acquired by Crompton Greaves , 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 Transportation and is now a part of Škoda Electric . Now
16459-469: The metal chassis of portable appliances and tools. Bonding all non-current-carrying metal parts into one complete system ensures there is always a low electrical impedance path to ground sufficient to carry any fault current for as long as it takes for the system to clear the fault. This low impedance path allows the maximum amount of fault current, causing the overcurrent protection device (breakers, fuses) to trip or burn out as quickly as possible, bringing
16610-574: The most part, mutually intelligible . The Hungarian Csángó dialect, which is mentioned but not listed separately by Ethnologue, is spoken primarily in Bacău County in eastern Romania. The Csángó Hungarian group has been largely isolated from other Hungarian people , and therefore preserved features that closely resemble earlier forms of Hungarian. Hungarian has 14 vowel phonemes and 25 consonant phonemes. The vowel phonemes can be grouped as pairs of short and long vowels such as o and ó . Most of
16761-553: The name of the country, " Magyarország " (Hungary), pronounced /ˈmɒɟɒrorsaːɡ/ . It is one of three palatal consonants, the others being ⟨ty⟩ and ⟨ny⟩ . Historically a fourth palatalized consonant ʎ existed, still written ⟨ly⟩ . A single 'r' is pronounced as an alveolar tap ( akkora 'of that size'), but a double 'r' is pronounced as an alveolar trill ( akkorra 'by that time'), like in Spanish and Italian . Primary stress
16912-442: The needs of the people of the city.[3] In 1845, he bought the neighbouring site and expanded his foundry with a cupola furnace. He gave his brother, Henrik a job as a clerk, because of the growing administration work. He made a profit in the first year, and his factory grew, even though he had not yet engaged in mass production. In 1846, at the third Hungarian Industrywork Exhibition (Magyar Iparmű Kiállítás), he introduced his stoves to
17063-407: The new information for the listeners that may not have been known or that their knowledge must be corrected. For example, "Én vagyok az apád". ('I am your father'. Literally, 'It is I who am your father'.), from the movie The Empire Strikes Back , the pronoun I ( én ) is in the focus and implies that it is new information, and the listener thought that someone else is his father. Although Hungarian
17214-425: The non-ideal metals forming the walls of the waveguide causes dissipation of power (surface currents flowing on lossy conductors dissipate power). At higher frequencies, the power lost to this dissipation becomes unacceptably large. At frequencies greater than 200 GHz, waveguide dimensions become impractically small, and the ohmic losses in the waveguide walls become large. Instead, fiber optics , which are
17365-443: The other Ugric languages. For example, Hungarian /aː/ corresponds to Khanty /o/ in certain positions, and Hungarian /h/ corresponds to Khanty /x/ , while Hungarian final /z/ corresponds to Khanty final /t/ . For example, Hungarian ház [haːz] ' house ' vs. Khanty xot [xot] ' house ' , and Hungarian száz [saːz] ' hundred ' vs. Khanty sot [sot] ' hundred ' . The distance between
17516-485: The pairs have an almost similar pronunciation and vary significantly only in their duration. However, pairs a / á and e / é differ both in closedness and length. Consonant length is also distinctive in Hungarian. Most consonant phonemes can occur as geminates . The sound voiced palatal plosive /ɟ/ , written ⟨gy⟩ , sounds similar to 'd' in British English 'duty'. It occurs in
17667-435: The paradigm for AC power transmission from a high voltage supply to a low voltage load was a series circuit. Open-core transformers with a ratio near 1:1 were connected with their primaries in series to allow use of a high voltage for transmission while presenting a low voltage to the lamps. The inherent flaw in this method was that turning off a single lamp (or other electric device) affected the voltage supplied to all others on
17818-431: The peak voltage (amplitude), we can rearrange the above equation to: For 230 V AC, the peak voltage V peak {\displaystyle V_{\text{peak}}} is therefore 230 V × 2 {\displaystyle 230{\text{ V}}\times {\sqrt {2}}} , which is about 325 V, and the peak power P peak {\displaystyle P_{\text{peak}}}
17969-556: The plant is operated by a new investor as a tenant, Ganz Transformer Motor and Manufacturing Ltd., after the previous owner was unable to finance the production. Timeline 1991: Joint Venture with Italian Ansaldo named Ganz Ansaldo Ltd. 1994: Air-cooled turbogenerator from 20 up to 70MVA 1998: Development of double-cage induction motor for twin-drives first on the world 2000: Acquisition by Tranelektro Group under name of Ganz-Transelektro 2001: Developed 1MW ExN Non-sparking gasturbine starter motors for GE 2002: First transformer in
18120-610: The power delivered is: where R {\displaystyle R} represents a load resistance. Rather than using instantaneous power, p ( t ) {\displaystyle p(t)} , it is more practical to use a time-averaged power (where the averaging is performed over any integer number of cycles). Therefore, AC voltage is often expressed as a root mean square (RMS) value, written as V rms {\displaystyle V_{\text{rms}}} , because For this reason, AC power's waveform becomes Full-wave rectified sine, and its fundamental frequency
18271-472: 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 . Prominent engineers at Ganz works included András Mechwart , Károly Zipernowsky , Miksa Déri , Ottó Titusz Bláthy , Kálmán Kandó , György Jendrassik and Ernő Wilczek . The invention of the modern industrial mill (the roller mill ) – by András Mechwart in 1874 – guaranteed
18422-411: The proposition is only for that particular thing or aspect, and it implies that the proposition is not true for some others. For example, in " Az almát János látja". ('It is John who sees the apple'. Literally 'The apple John sees.'), the apple is in the topic, implying that other objects may be seen by not him but other people (the pear may be seen by Peter). The topic part may be empty. The focus shows
18573-543: The public. He won the silver medal of the exhibition committee and the bronze medaille from Archduke Joseph, Palatine of Hungary. During the Hungarian Revolution of 1848 the foundry made ten cannons and many cannonballs for the Hungarian army. Because of this, the Military Court of Austria impeached him. He got seven weeks in prison as penalty, but because of his Swiss citizenship he was acquitted of
18724-615: The rapid railway development in Central Europe. 86,074 pieces of hard cast wheels had been sold to 59 European railway companies until 1866. Consequently, this factory played an important role in building the infrastructure of the Hungarian Kingdom and the Austro-Hungarian Empire . At this time the agricultural machines , steam locomotives , pumps and the railway carriages were the main products. At
18875-492: The same circuit. Many adjustable transformer designs were introduced to compensate for this problematic characteristic of the series circuit, including those employing methods of adjusting the core or bypassing the magnetic flux around part of a coil. The direct current systems did not have these drawbacks, giving it significant advantages over early AC systems. In the UK, Sebastian de Ferranti , who had been developing AC generators and transformers in London since 1882, redesigned
19026-414: The same phases with reverse polarity and so can be simply wired together. In practice, higher "pole orders" are commonly used. For example, a 12-pole machine would have 36 coils (10° spacing). The advantage is that lower rotational speeds can be used to generate the same frequency. For example, a 2-pole machine running at 3600 rpm and a 12-pole machine running at 600 rpm produce the same frequency;
19177-411: The skin depth of a copper conductor is approximately 8.57 mm at 60 Hz, so high current conductors are usually hollow to reduce their mass and cost. This tendency of alternating current to flow predominantly in the periphery of conductors reduces the effective cross-section of the conductor. This increases the effective AC resistance of the conductor, since resistance is inversely proportional to
19328-585: The standards for the complete system of generation, transmission and motors used in USA today. The original Niagara Falls Adams Power Plant with three two-phase generators was put into operation in August 1895, but was connected to the remote transmission system only in 1896. The Jaruga Hydroelectric Power Plant in Croatia was set in operation two days later, on 28 August 1895. Its generator (42 Hz, 240 kW)
19479-410: The supply side. For smaller customers (just how small varies by country and age of the installation) only a single phase and neutral, or two phases and neutral, are taken to the property. For larger installations all three phases and neutral are taken to the main distribution panel. From the three-phase main panel, both single and three-phase circuits may lead off. Three-wire single-phase systems, with
19630-414: The surrounding 7 countries, so it is widely spoken or understood. Although host countries are not always considerate of Hungarian language users, communities are strong. The Szeklers , for example, form their own region and have their own national museum, educational institutions, and hospitals. Hungarian has about 13 million native speakers, of whom more than 9.8 million live in Hungary. According to
19781-646: The task of redesigning the Gaulard and Gibbs transformer for commercial use in United States. On March 20, 1886, Stanley conducted a demonstrative experiment in Great Barrington : A Siemens generator's voltage of 500 volts was converted into 3000 volts, and then the voltage was stepped down to 500 volts by six Westinghouse transformers. With this setup, the Westinghouse company successfully powered thirty 100-volt incandescent bulbs in twenty shops along
19932-517: The total word count is difficult, since it is hard to define a "word" in agglutinating languages, due to the existence of affixed words and compound words. To obtain a meaningful definition of compound words, it is necessary to exclude compounds whose meaning is the mere sum of its elements. The largest dictionaries giving translations from Hungarian to another language contain 120,000 words and phrases (but this may include redundant phrases as well, because of translation issues) . The new desk lexicon of
20083-403: The upstream distribution panel to handle harmonics . Harmonics can cause neutral conductor current levels to exceed that of one or all phase conductors. For three-phase at utilization voltages a four-wire system is often used. When stepping down three-phase, a transformer with a Delta (3-wire) primary and a Star (4-wire, center-earthed) secondary is often used so there is no need for a neutral on
20234-578: The use of parallel connected, instead of series connected, utilization loads, the other concerning the ability to have high turns ratio transformers such that the supply network voltage could be much higher (initially 1400 V to 2000 V) than the voltage of utilization loads (100 V initially preferred). When employed in parallel connected electric distribution systems, closed-core transformers finally made it technically and economically feasible to provide electric power for lighting in homes, businesses and public spaces. The other essential milestone
20385-519: The way to integrate older plants into a universal AC supply system. In the autumn of 1884, Károly Zipernowsky , Ottó Bláthy and Miksa Déri (ZBD), three engineers associated with the Ganz Works of Budapest, determined that open-core devices were impractical, as they were incapable of reliably regulating voltage. Bláthy had suggested the use of closed cores, Zipernowsky had suggested the use of parallel shunt connections , and Déri had performed
20536-477: The wire are a product of the square of the current ( I ) and the resistance (R) of the wire, described by the formula: This means that when transmitting a fixed power on a given wire, if the current is halved (i.e. the voltage is doubled), the power loss due to the wire's resistance will be reduced to one quarter. The power transmitted is equal to the product of the current and the voltage (assuming no phase difference); that is, Consequently, power transmitted at
20687-459: The world for 123 kV with ester liquid 2006: Became a Part of Crompton Greaves Ltd as CG Electric Systerms Hungary Hungarian language Hungarian , or Magyar ( magyar nyelv , pronounced [ˈmɒɟɒr ˈɲɛlv] ), is a Uralic language of the Ugric branch spoken in Hungary and parts of several neighboring countries. It is the official language of Hungary and one of
20838-561: Was a 6 HP pit locomotive with direct current traction system. The first Ganz made asynchronous rail vehicles (altogether 2 pieces) were supplied in 1898 to Évian-les-Bains (France) with a 37 HP asynchronous traction system. The Ganz Works won the tender for electrification of the Valtellina Railway in Italy in 1897. Under the management, and on the basis of plans from Kálmán Kandó, three phase electric power at 3 kV and 15 Hz
20989-465: Was designed by engineers of the Ganz Works in 1866. Mass production of dynamo generators started in 1883. The missing link of a full Voltage Sensitive/Voltage Intensive (VSVI) system was the reliable alternating current constant voltage generator. Therefore, the invention of the constant voltage generator by the Ganz Works in 1883 had a crucial role in the beginnings of industrial scale AC power generation, because only these type of generators can produce
21140-403: Was fed through two upper wires and the rails. The electricity was produced in a dedicated power station and the system operated for thirty years from 1902. Italian railways were the first in the world to introduce electric traction for the entire length of a main line rather than just a short stretch. The 106 km Valtellina line was opened on 4 September 1902, designed by Kandó and a team from
21291-568: Was in the hands of Röck and Ganz Works. The contract between Ganz and Egypt in the 1930s played a key role in the development of cooling equipment: railcars delivered to Egypt were equipped with air-conditioning cooling systems. The collective of the Ganz factory (machine designers: Gábor Hollerung, Rezső Oláh, István Pfeifer, Prónai) designed and built the 3-cylinder, 20 kW compressors with freon refrigerant, air condenser and evaporator. The machine could also be converted to heat pump operation. The beginning of gas engine manufacturing in Hungary
21442-560: Was independently invented by Galileo Ferraris and Nikola Tesla (with Tesla's design being licensed by Westinghouse in the US). This design was independently further developed into the modern practical three-phase form by Mikhail Dolivo-Dobrovolsky and Charles Eugene Lancelot Brown in Germany on one side, and Jonas Wenström in Sweden on the other, though Brown favoured the two-phase system. A long-distance alternating current transmission
21593-547: Was installed in Telluride Colorado. The first three-phase system was established in 1891 in Frankfurt , Germany. The Tivoli – Rome transmission was completed in 1892. The San Antonio Canyon Generator was the third commercial single-phase hydroelectric AC power plant in the United States to provide long-distance electricity. It was completed on December 31, 1892, by Almarian William Decker to provide power to
21744-450: Was made and installed by the Hungarian company Ganz , while the transmission line from the power plant to the City of Šibenik was 11.5 kilometers (7.1 mi) long, and the municipal distribution grid 3000 V/110 V included six transforming stations. Alternating current circuit theory developed rapidly in the latter part of the 19th and early 20th century. Notable contributors to
21895-596: Was not feasible in the early days of electric power transmission , as there was then no economically viable way to step the voltage of DC down for end user applications such as lighting incandescent bulbs. Three-phase electrical generation is very common. The simplest way is to use three separate coils in the generator stator , physically offset by an angle of 120° (one-third of a complete 360° phase) to each other. Three current waveforms are produced that are equal in magnitude and 120° out of phase to each other. If coils are added opposite to these (60° spacing), they generate
22046-574: Was planned to be fitted to the Varga RMI-1 X/H twin-engined reconnaissance bomber designed by László Varga in 1940, but the program was cancelled. Jendrassik had also designed a small-scale 75 kW turboprop in 1937. In 1947, the Ganz Works was nationalised and in 1949 it became independent and six big companies came into existence, including the Ganz Transformer Factory. In 1959, Ganz Wagon and Machine Factory merged with
22197-509: Was responsible for building the dreadnought SMS Szent István , all of the Novara -class cruisers , and built diesel-electric U-boats at its shipyard in Budapest, for final assembly at Fiume . Several U-boats of the U-XXIX class , U-XXX class , U-XXXI class and U-XXXII class were completed, A number of other types were laid down, but remained incomplete at the war's end. By the end of
22348-990: Was that it was fed by the normal power network, so dedicated railway power stations became unnecessary. Because of the early death of Kálmán Kandó, László Verebélÿ continued the work for the Hungarian State Railways (MÁV). In 1959 Ganz merged with the MÁVAG company and was renamed Ganz-MÁVAG . In 1976 Ganz-Mávag supplied ten standard gauge 3-car diesel trainset to the Hellenic Railways Organisation (OSE), designated as Class AA-91 and four metre gauge 4-car trainsets, designated as Class A-6451. In 1981/82 Ganz-Mávag supplied to OSE 11 B-B diesel-hydraulic DHM7-9 locomotives, designated as class A-251. Finally, in 1983, OSE bought eleven 3-car metre gauge trainsets, designated as Class A-6461. All these locomotives and trainsets have been withdrawn with
22499-506: Was the introduction of 'voltage source, voltage intensive' (VSVI) systems' by the invention of constant voltage generators in 1885. In early 1885, the three engineers also eliminated the problem of eddy current losses with the invention of the lamination of electromagnetic cores. Ottó Bláthy also invented the first AC electricity meter . The AC power system was developed and adopted rapidly after 1886 due to its ability to distribute electricity efficiently over long distances, overcoming
22650-490: Was transformed into a joint-stock company, and continued its operations under the name of "Ganz és Társa vasontöde és Gépgyár Rt." (Ganz & Partners Iron Foundry and Machine Factory Co.) The technical director was András Mechwart, under whose direction Ganz became one of the most important groups of machine building companies in the Austro-Hungarian Monarchy after 1869. At the end of the 19th century,
22801-754: Was used in 1883 for the Metropolitan Railway station lighting in London , while the single-phase 1884 system in Turin , Italy, was the first multiple-user AC distribution system in the world. The Ames Hydroelectric Generating Plant , constructed in 1890, was among the first hydroelectric alternating current power plants. A long distance transmission of single-phase electricity from a hydroelectric generating plant in Oregon at Willamette Falls sent power fourteen miles downriver to downtown Portland for street lighting in 1890. In 1891, another transmission system
