b. 22 March 1840 Cincinnati, Ohio, USA

[br]

American mechanical engineer, pioneer in experiments with magnetic recording.

[br]

Of English descent, Smith embarked on an education in mechanical engineering, graduating from West Jersey Academy, Bridgeton, New Jersey, in 1859. In 1863 he established a machine shop in Bridgeton, New Jersey, that became the Ferracute Machine Company in 1877, eventually specializing in the manufacture of presses for metalworking. He seems to have subscribed to design principles considered modern even in the 1990s, "always giving attention to the development of artistic form in combination with simplicity, and with massive strength where required" (bibliographic reference below). He was successful in his business, and developed and patented a large number of mechanical constructions.

Inspired by the advent of the phonograph of Edison, in 1878 Smith obtained the tin-foil mechanical phonograph, analysed its shortcomings and performed some experiments in magnetic recording. He filed a caveat in the US Patent Office in order to be protected while he "reduced the invention to practice". However, he did not follow this trail. When there was renewed interest in practical sound recording and reproduction in 1888 (the constructions of Berliner and Bell \& Tainter), Smith published an account of his experiments in the journal Electrical World. In a corrective letter three weeks later it is clear that he was aware of the physical requirements for the interaction between magnetic coil and magnetic medium, but his publications also indicate that he did not as such obtain reproduction of recorded sound.

Smith did not try to develop magnetic recording, but he felt it imperative that he be given credit for conceiving the idea of it. When accounts of Valdemar Poulsen's work were published in 1900, Smith attempted to prove some rights in the invention in the US Patent Office, but to no avail.

He was a highly respected member of both his community and engineering societies, and in later life became interested in the anti-slavery cause that had also been close to the heart of his parents, as well as in the YMCA movement and in women's suffrage.

Bibliography

Apart from numerous technical papers, he wrote the book Press Working of Metals, 1896. His accounts on the magnetic recording experiments were "Some possible forms of phonograph", Electrical World (8 September 1888): 161 ff, and "Letter to the Editor", Electrical World (29 September 1888): 179.

[br]

Scottish chemist, pioneer of electric power and builder of the first electric railway locomotives.

[br]

Davidson, son of an Aberdeen merchant, attended Marischal College, Aberdeen, between 1819 and 1822: his studies included mathematics, mechanics and chemistry. He subsequently joined his father's grocery business, which from time to time received enquiries for yeast: to meet these, Davidson began to manufacture yeast for sale and from that start built up a successful chemical manufacturing business with the emphasis on yeast and dyes. About 1837 he started to experiment first with electric batteries and then with motors. He invented a form of electromagnetic engine in which soft iron bars arranged on the periphery of a wooden cylinder, parallel to its axis, around which the cylinder could rotate, were attracted by fixed electromagnets. These were energized in turn by current controlled by a simple commutaring device. Electric current was produced by his batteries. His activities were brought to the attention of Michael Faraday and to the scientific world in general by a letter from Professor Forbes of King's College, Aberdeen. Davidson declined to patent his inventions, believing that all should be able freely to draw advantage from them, and in order to afford an opportunity for all interested parties to inspect them an exhibition was held at 36 Union Street, Aberdeen, in October 1840 to demonstrate his "apparatus actuated by electro-magnetic power". It included: a model locomotive carriage, large enough to carry two people, that ran on a railway; a turning lathe with tools for visitors to use; and a small printing machine. In the spring of 1842 he put on a similar exhibition in Edinburgh, this time including a sawmill. Davidson sought support from railway companies for further experiments and the construction of an electromagnetic locomotive; the Edinburgh exhibition successfully attracted the attention of the proprietors of the Edinburgh 585\& Glasgow Railway (E \& GR), whose line had been opened in February 1842. Davidson built a full-size locomotive incorporating his principle, apparently at the expense of the railway company. The locomotive weighed 7 tons: each of its two axles carried a cylinder upon which were fastened three iron bars, and four electromagnets were arranged in pairs on each side of the cylinders. The motors he used were reluctance motors, the power source being zinc-iron batteries. It was named Galvani and was demonstrated on the E \& GR that autumn, when it achieved a speed of 4 mph (6.4 km/h) while hauling a load of 6 tons over a distance of 1 1/2 miles (2.4 km); it was the first electric locomotive. Nevertheless, further support from the railway company was not forthcoming, although to some railway workers the locomotive seems to have appeared promising enough: they destroyed it in Luddite reaction. Davidson staged a further exhibition in London in 1843 without result and then, the cost of battery chemicals being high, ceased further experiments of this type. He survived long enough to see the electric railway become truly practicable in the 1880s.

[br]

English physicist awarded the Nobel Prize for Physics for his discovery of the ionospheric layer, named after him, which is an efficient reflector of short radio waves, thereby making possible long-distance radio communication.

[br]

After early ambitions to become a professional cricketer, Appleton went to St John's College, Cambridge, where he studied under J.J.Thompson and Ernest Rutherford. His academic career interrupted by the First World War, he served as a captain in the Royal Engineers, carrying out investigations into the propagation and fading of radio signals. After the war he joined the Cavendish Laboratory, Cambridge, as a demonstrator in 1920, and in 1924 he moved to King's College, London, as Wheatstone Professor of Physics.

In the following decade he contributed to developments in valve oscillators (in particular, the "squegging" oscillator, which formed the basis of the first hard-valve time-base) and gained international recognition for research into electromagnetic-wave propagation. His most important contribution was to confirm the existence of a conducting ionospheric layer in the upper atmosphere capable of reflecting radio waves, which had been predicted almost simultaneously by Heaviside and Kennelly in 1902. This he did by persuading the BBC in 1924 to vary the frequency of their Bournemouth transmitter, and he then measured the signal received at Cambridge. By comparing the direct and reflected rays and the daily variation he was able to deduce that the Kennelly- Heaviside (the so-called E-layer) was at a height of about 60 miles (97 km) above the earth and that there was a further layer (the Appleton or F-layer) at about 150 miles (240 km), the latter being an efficient reflector of the shorter radio waves that penetrated the lower layers. During the period 1927–32 and aided by Hartree, he established a magneto-ionic theory to explain the existence of the ionosphere. He was instrumental in obtaining agreement for international co-operation for ionospheric and other measurements in the form of the Second Polar Year (1932–3) and, much later, the International Geophysical Year (1957–8). For all this work, which made it possible to forecast the optimum frequencies for long-distance short-wave communication as a function of the location of transmitter and receiver and of the time of day and year, in 1947 he was awarded the Nobel Prize for Physics.

He returned to Cambridge as Jacksonian Professor of Natural Philosophy in 1939, and with M.F. Barnett he investigated the possible use of radio waves for radio-location of aircraft. In 1939 he became Secretary of the Government Department of Scientific and Industrial Research, a post he held for ten years. During the Second World War he contributed to the development of both radar and the atomic bomb, and subsequently served on government committees concerned with the use of atomic energy (which led to the establishment of Harwell) and with scientific staff.

The switchboard plays an essential role in the availability of electric power, while meeting the needs of personal and property safety.

Its definition, design and installation are based on precise rules; there is no place for improvisation.

The IEC 61439 standard aims to better define " low-voltage switchgear and controlgear assemblies", ensuring that the specified performances are reached.

It specifies in particular:

> the responsibilities of each player, distinguishing those of the original equipment manufacturer - the organization that performed the original design and associated verification of an assembly in accordance with the standard, and of the assembly manufacturer - the organization taking responsibility for the finished assembly;

> the design and verification rules, constituting a benchmark for product certification.

All the component parts of the electrical switchboard are concerned by the IEC 61439 standard.

Equipment produced in accordance with the requirements of this switchboard standard ensures the safety and reliability of the installation.

A switchboard must comply with the requirements of standard IEC 61439-1 and 2 to guarantee the safety and reliability of the installation.

Managers of installations, fully aware of the professional and legal liabilities weighing on their company and on themselves, demand a high level of safety for the electrical installation.

What is more, the serious economic consequences of prolonged halts in production mean that the electrical switchboard must provide excellent continuity of service, whatever the operating conditions.

НКУ играет главную роль в обеспечении электроэнергией, удовлетворяя при этом всем требованиям по безопасности людей и сохранности имущества.

Выбор конструкции, проектирование и монтаж основаны на чётких правилах, не допускающих никакой импровизации.

Требования к низковольтным комплектным устройствам распределения и управления сформулированы в стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000).

В частности, он определяет:

> распределение ответственности между изготовителем НКУ - организацией, разработавшей конструкцию НКУ и проверившей его на соответствие требованиям стандарта, и сборщиком – организацией, выполнившей сборку НКУ;

> конструкцию, технические характеристики, виды и методы испытаний НКУ.

В стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000) описываются все компоненты НКУ.

Оборудование, изготовленное в соответствии с требованиями этого стандарта, обеспечивает безопасность и надежность электроустановки.

Для того чтобы гарантировать безопасность эксплуатации и надежность работы электроустановки, распределительный щит должен соответствовать требованиям стандарта МЭК 61439-1 и 2.

Лица, ответственные за электроустановки, должны быть полностью осведомлены о профессиональной и юридической ответственности, возложенной на их компанию и на них лично, за обеспечение высокого уровня безопасности эксплуатации этих электроустановок.

Кроме того, поскольку длительные перерывы производства приводят к серьезным экономическим последствиям, электрический распределительный щит должен обеспечивать надежную и бесперебойную работу независимо от условий эксплуатации.

[Перевод Интент]

LV switchgear assemblies are undoubtedly the components of the electric installation more subject to the direct intervention of personnel (operations, maintenance, etc.) and for this reason users demand from them higher and higher safety requirements.

The compliance of an assembly with the state of the art and therefore, presumptively, with the relevant technical Standard, cannot be based only on the fact that the components which constitute it comply with the state of the art and therefore, at least presumptively, with the relevant technical standards.

In other words, the whole assembly must be designed, built and tested in compliance with the state of the art.

Since the assemblies under consideration are low voltage equipment, their rated voltage shall not exceed 1000 Va.c. or 1500 Vd.c. As regards currents, neither upper nor lower limits are provided in the application field of this Standard.

The Standard IEC 60439-1 states the construction, safety and maintenance requirements for low voltage switchgear and controlgear assemblies, without dealing with the functional aspects which remain a competence of the designer of the plant for which the assembly is intended.

Низковольтные комплектные устройства (НКУ), вне всякого сомнения, являются частями электроустановок, которые наиболее подвержены непосредственному вмешательству оперативного, обслуживающего и т. п. персонала. Вот почему требования потребителей к безопасности НКУ становятся все выше и выше.

Соответствие НКУ современному положению дел и вследствие этого, гипотетически, соответствующим техническим стандартам, не может основываться только на том факте, что составляющие НКУ компоненты соответствуют современному состоянию дел и поэтому, по крайней мере, гипотетически, - соответствующим техническим стандартам

Другими словами, НКУ должно быть разработано, изготовлено и испытано в соответствии с современными требованиями.

Мы рассматриваем низковольтные комплектные устройства и это означает, что их номинальное напряжение не превышает 1000 В переменного тока или 1500 В постоянного тока. Что касается тока, то ни верхнее, ни нижнее значение стандартами, относящимися к данной области, не оговариваются

Стандарт МЭК 60439-1 устанавливает требования к конструкции, безопасности и техническому обслуживанию низковольтных комплектных устройств без учета их функций, полагая, что функции НКУ являются компетенцией проектировщиков электроустановки, частью которых эти НКУ являются.

[ http://energy-ua.com/elektricheskie-p/klassifikatsiya.html]

КЛАССИФИКАЦИЯ

В общем случае ПС и РУ являются составной частью электроустановок, которые различаются:
- по назначению:
  - генерирующие,
  - преобразовательно-распределительные,
  - потребительские.
    
    Генерирующие электроустановки служат для выработки электроэнергии, преобразовательно-распределительные электроустановки преобразуют электроэнергию в удобный для передачи и потребления вид, передают ее и распределяют между потребителями;
- по роду тока:
  - постоянного тока,
  - переменного тока.
- по напряжению:
  - до 1000 В,
  - выше 1000 В.
Шкала номинальных напряжений ограничена сравнительно небольшим числом стандартных значений, благодаря чему изготавливается небольшое число типоразмеров машин и оборудования, а электросети выполняются более экономичными. В установках трехфазного тока номинальным напряжением принято считать напряжение между фазами (междуфазовое напряжение). Согласно ГОСТ 29322—92 установлена следующая шкала номинальных напряжений:

для электросетей переменного тока частотой 50 Гц междуфазовое напряжение должно быть: 12, 24, 36, 42, 127, 220, 380 В; 3, 6, 10, 20, 35, 110, 150, 220, 330, 500, 750 и 1150 кВ;
для электросетей постоянного тока: 12, 24, 36, 48, 60, 110, 220, 440, 660, 825, 3000 В и выше.
- по способу присоединения к электросети ПС разделяются на:
  - тупиковые (блочные),
  - ответвительные (блочные),
  - проходные (транзитные)
  - узловые.
Тупиковые ПС получают питание по одной или двум тупиковым ВЛ.

Ответвительные ПС присоединяются ответвлением к одной или двум проходящим ВЛ с односторонним или двухсторонним питанием.

Проходные ПС включаются в рассечку одной или двух проходящих ВЛ с односторонним или двухсторонним питанием.

Узловые ПС кроме питающих имеют отходящие радиальные или транзитные ВЛ.
- по способу управления ПС могут быть:
  - только с телесигнализацией,
  - телеуправляемыми с телесигнализацией,
  - с телесигнализацией и управлением с общеподстанционного пункта управления (ОПУ).
Подстанции оперативно обслуживаются постоянным дежурным персоналом на щите управления, дежурными на дому или оперативно-выездными бригадами (ОВБ). Ремонт ПС осуществляется специализированными выездными бригадами централизованного ремонта или местным персоналом подстанции.

В РУ напряжением до 1000 В провода, шины, аппараты, приборы и конструкции выбирают как по нормальным условиям работы (напряжению и току), так и по термическим и динамическим воздействиям токов коротких замыканий (КЗ) или предельно допустимой отключаемой мощности.

В РУ и ПС напряжением выше 1000 В расстояния между электрооборудованием, аппаратами, токоведущими частями, изоляторами, ограждениями и конструкциями устанавливаются так, чтобы при нормальном режиме работы электроустановки возникающие физические явления (температура нагрева, электрическая дуга, выброс газов, искрение и др.) не могли привести к повреждению оборудования и КЗ.

Several different classifications of switchgear can be made:
- By the current rating.
- By interrupting rating (maximum short circuit current that the device can safely interrupt)
  - Circuit breakers can open and close on fault currents
  - Load-break/Load-make switches can switch normal system load currents
  - Isolators may only be operated while the circuit is dead, or the load current is very small.

  - Low voltage (less than 1,000 volts AC)
  - Medium voltage (1,000–35,000 volts AC)
  - High voltage (more than 35,000 volts AC)
- By insulating medium:
  - Air
  - Gas (SF6 or mixtures)
  - Oil
  - Vacuum
- By construction type:
  - Indoor (further classified by IP (Ingress Protection) class or NEMA enclosure type)
  - Outdoor
  - Industrial
  - Utility

A single line-up may incorporate several different types of devices, for example, air-insulated bus, vacuum circuit breakers, and manually operated switches may all exist in the same row of cubicles.

Ratings, design, specifications and details of switchgear are set by a multitude of standards. In North America mostly IEEE and ANSI standards are used, much of the rest of the world uses IEC standards, sometimes with local national derivatives or variations.

Distribution switchboards, including the Main LV Switchboard (MLVS), are critical to the dependability of an electrical installation. They must comply with well-defined standards governing the design and construction of LV switchgear assemblies

A distribution switchboard is the point at which an incoming-power supply divides into separate circuits, each of which is controlled and protected by the fuses or switchgear of the switchboard. A distribution switchboard is divided into a number of functional units, each comprising all the electrical and mechanical elements that contribute to the fulfilment of a given function. It represents a key link in the dependability chain.

Consequently, the type of distribution switchboard must be perfectly adapted to its application. Its design and construction must comply with applicable standards and working practises.

[Schneider Electric]

Распределительные щиты, включая главный распределительный щит низкого напряжения (ГРЩ), играют решающую роль в обеспечении надежности электроустановки. Они должны отвечать требованиям соответствующих стандартов, определяющих конструкцию и порядок изготовления НКУ распределения электроэнергии.

В распределительном щите выполняется прием электроэнергии и ее распределение по отдельным цепям, каждая из которых контролируется и защищается плавкими предохранителями или автоматическими выключателями.
Распределительный щит состоит из функциональных блоков, включающих в себя все электрические и механические элементы, необходимые для выполнения требуемой функции. Распределительный щит представляет собой ключевое звено в цепи обеспечения надежности.

Тип распределительного щита должен соответствовать области применения. Конструкция и изготовление распределительного щита должны удовлетворять требованиям применимых стандартов и учитывать накопленную практику применения.

The switchboard, central to the electrical installation.

Both the point of arrival of energy and a device for distribution to the site applications, the LV switchboard is the intelligence of the system, central to the electrical installation.

[Schneider Electric]

Распределительный щит – «сердце» электроустановки.

Низковольтное комплектное устройство распределения является «сердцем» электроустановки, поскольку именно оно принимает электроэнергию из сети и распределяет её по территориально распределенным нагрузкам.

SUBJECT AREA: Electronics and information technology

[br]

b. 26 June 1911 Stockport, Cheshire, England

d. 11 August 1977 Prestbury, Cheshire, England

[br]

English electrical engineer who invented the Williams storage cathode ray tube, which was extensively used worldwide as a data memory in the first digital computers.

[br]

Following education at Stockport Grammar School, Williams entered Manchester University in 1929, gaining his BSc in 1932 and MSc in 1933. After a short time as a college apprentice with Metropolitan Vickers, he went to Magdalen College, Oxford, to study for a DPhil, which he was awarded in 1936. He returned to Manchester University that year as an assistant lecturer, gaining his DSc in 1939. Following the outbreak of the Second World War he worked for the Scientific Civil Service, initially at the Bawdsey Research Station and then at the Telecommunications Research Establishment at Malvern, Worcestershire. There he was involved in research on non-incandescent amplifiers and diode rectifiers and the development of the first practical radar system capable of identifying friendly aircraft. Later in the war, he devised an automatic radar system suitable for use by fighter aircraft.

After the war he resumed his academic career at Manchester, becoming Professor of Electrical Engineering and Director of the University Electrotechnical Laboratory in 1946. In the same year he succeeded in developing a data-memory device based on the cathode ray tube, in which the information was stored and read by electron-beam scanning of a charge-retaining target. The Williams storage tube, as it became known, not only found obvious later use as a means of storing single-frame, still television images but proved to be a vital component of the pioneering Manchester University MkI digital computer. Because it enabled both data and program instructions to be stored in the computer, it was soon used worldwide in the development of the early stored-program computers.

[br]

b. 14 April 1898 Leominster, Massachusetts, USA

d. 11 December 1983 Summitt, New Jersey, USA

[br]

American electrical engineer who discovered that the application of negative feedback to amplifiers improved their stability and reduced distortion.

[br]

Black graduated from Worcester Polytechnic Institute, Massachusetts, in 1921 and joined the Western Electric Company laboratories (later the Bell Telephone Laboratories) in New York City. There he worked on a variety of electronic-communication problems. His major contribution was the discovery in 1927 that the application of negative feedback to an amplifier, whereby a fraction of the output signal is fed back to the input in the opposite phase, not only increases the stability of the amplifier but also has the effect of reducing the magnitude of any distortion introduced by it. This discovery has found wide application in the design of audio hi-fi amplifiers and various control systems, and has also given valuable insight into the way in which many animal control functions operate.

During the Second World War he developed a form of pulse code modulation (PCM) to provide a practicable, secure telephony system for the US Army Signal Corps. From 1963–6, after his retirement from the Bell Labs, he was Principal Research Scientist with General Precision Inc., Little Falls, New Jersey, following which he became an independent consultant in communications. At the time of his death he held over 300 patents.

[br]

b. 1856 Columbus, Ohio, USA

d. 1919 New York (?), USA

[br]

African-American inventor of electrical equipment.

[br]

He was first apprenticed in Columbus as a machinist and blacksmith. In 1872 he moved to Missouri, where he was engaged as a fireman and then engine-driver on the Iron Mountain Railroad. In his spare time he devoted much time to the study of electrical engineering. In 1878 he went to sea for two years as engineer on a British vessel. He returned to Ohio, taking up his previous occupation as engine-driver, and in 1884 he achieved his first patent, for a locomotive firebox. However, the drive towards things electrical was too strong and he set up the Woods Electric Company in Cincinnati, Ohio, to develop and market electrical inventions. Woods gained some fame as an inventor and became known as the "black Edison ". His first device, a telephone transmitter, was patented in December 1884 but faced stiff competition from similar inventions by Alexander Graham Bell and others. The following year he patented a device for transmitting messages in Morse code or by voice that was valuable enough to be bought up by the Bell Telephone Company. A stream of inventions followed, particularly for railway telegraph and electrical systems. This brought him into conflict with Edison, who was working in the same field. The US Patent Office ruled in Woods's favour; as a result of the ensuing publicity, one newspaper hailed Woods as the "greatest electrician in the world". In 1890 Woods moved to New York, where the opportunities for an electrical engineer seemed more favourable. He turned his attention to inventions that would improve the tram-car. One device enabled electric current to be transferred to the car with less friction than previously, incorporating a grooved wheel known as a "troller", whence came the popular term "trolley car".

[ http://energy-ua.com/elektricheskie-p/klassifikatsiya.html]

КЛАССИФИКАЦИЯ

В общем случае ПС и РУ являются составной частью электроустановок, которые различаются:
- по назначению:
  - генерирующие,
  - преобразовательно-распределительные,
  - потребительские.
    
    Генерирующие электроустановки служат для выработки электроэнергии, преобразовательно-распределительные электроустановки преобразуют электроэнергию в удобный для передачи и потребления вид, передают ее и распределяют между потребителями;
- по роду тока:
  - постоянного тока,
  - переменного тока.
- по напряжению:
  - до 1000 В,
  - выше 1000 В.
Шкала номинальных напряжений ограничена сравнительно небольшим числом стандартных значений, благодаря чему изготавливается небольшое число типоразмеров машин и оборудования, а электросети выполняются более экономичными. В установках трехфазного тока номинальным напряжением принято считать напряжение между фазами (междуфазовое напряжение). Согласно ГОСТ 29322—92 установлена следующая шкала номинальных напряжений:

для электросетей переменного тока частотой 50 Гц междуфазовое напряжение должно быть: 12, 24, 36, 42, 127, 220, 380 В; 3, 6, 10, 20, 35, 110, 150, 220, 330, 500, 750 и 1150 кВ;
для электросетей постоянного тока: 12, 24, 36, 48, 60, 110, 220, 440, 660, 825, 3000 В и выше.
- по способу присоединения к электросети ПС разделяются на:
  - тупиковые (блочные),
  - ответвительные (блочные),
  - проходные (транзитные)
  - узловые.
Тупиковые ПС получают питание по одной или двум тупиковым ВЛ.

Ответвительные ПС присоединяются ответвлением к одной или двум проходящим ВЛ с односторонним или двухсторонним питанием.

Проходные ПС включаются в рассечку одной или двух проходящих ВЛ с односторонним или двухсторонним питанием.

Узловые ПС кроме питающих имеют отходящие радиальные или транзитные ВЛ.
- по способу управления ПС могут быть:
  - только с телесигнализацией,
  - телеуправляемыми с телесигнализацией,
  - с телесигнализацией и управлением с общеподстанционного пункта управления (ОПУ).
Подстанции оперативно обслуживаются постоянным дежурным персоналом на щите управления, дежурными на дому или оперативно-выездными бригадами (ОВБ). Ремонт ПС осуществляется специализированными выездными бригадами централизованного ремонта или местным персоналом подстанции.

В РУ напряжением до 1000 В провода, шины, аппараты, приборы и конструкции выбирают как по нормальным условиям работы (напряжению и току), так и по термическим и динамическим воздействиям токов коротких замыканий (КЗ) или предельно допустимой отключаемой мощности.

В РУ и ПС напряжением выше 1000 В расстояния между электрооборудованием, аппаратами, токоведущими частями, изоляторами, ограждениями и конструкциями устанавливаются так, чтобы при нормальном режиме работы электроустановки возникающие физические явления (температура нагрева, электрическая дуга, выброс газов, искрение и др.) не могли привести к повреждению оборудования и КЗ.

[ http://energy-ua.com/elektricheskie-p/klassifikatsiya.html]

Several different classifications of switchgear can be made:
- By the current rating.
- By interrupting rating (maximum short circuit current that the device can safely interrupt)
  - Circuit breakers can open and close on fault currents
  - Load-break/Load-make switches can switch normal system load currents
  - Isolators may only be operated while the circuit is dead, or the load current is very small.
- By voltage class:
  - Low voltage (less than 1,000 volts AC)
  - Medium voltage (1,000–35,000 volts AC)
  - High voltage (more than 35,000 volts AC)
- By insulating medium:
  - Air
  - Gas (SF6 or mixtures)
  - Oil
  - Vacuum
- By construction type:
  - Indoor (further classified by IP (Ingress Protection) class or NEMA enclosure type)
  - Outdoor
  - Industrial
  - Utility
  - Marine
  - Draw-out elements (removable without many tools)
  - Fixed elements (bolted fasteners)
  - Live-front
  - Dead-front
  - Open
  - Metal-enclosed
  - Metal-clad
  - Metal enclosed & Metal clad
  - Arc-resistant
- By IEC degree of internal separation
  - No Separation (Form 1)
  - Busbars separated from functional units (Form 2a, 2b, 3a, 3b, 4a, 4b)
  - Terminals for external conductors separated from busbars (Form 2b, 3b, 4a, 4b)
  - Terminals for external conductors separated from functional units but not from each other (Form 3a, 3b)
  - Functional units separated from each other (Form 3a, 3b, 4a, 4b)
  - Terminals for external conductors separated from each other (Form 4a, 4b)
  - Terminals for external conductors separate from their associated functional unit (Form 4b)
- By interrupting device:
- By operating method:
  - Manually operated
  - Motor/stored energy operated
  - Solenoid operated
- By type of current:
  - Alternating current
  - Direct current
- By application:
  - Transmission system
  - Distribution
- By purpose
  - Isolating switches (disconnectors)
  - Load-break switches.
  - Grounding (earthing) switches
A single line-up may incorporate several different types of devices, for example, air-insulated bus, vacuum circuit breakers, and manually operated switches may all exist in the same row of cubicles.

Ratings, design, specifications and details of switchgear are set by a multitude of standards. In North America mostly IEEE and ANSI standards are used, much of the rest of the world uses IEC standards, sometimes with local national derivatives or variations.

Distribution switchboards, including the Main LV Switchboard (MLVS), are critical to the dependability of an electrical installation. They must comply with well-defined standards governing the design and construction of LV switchgear assemblies

A distribution switchboard is the point at which an incoming-power supply divides into separate circuits, each of which is controlled and protected by the fuses or switchgear of the switchboard. A distribution switchboard is divided into a number of functional units, each comprising all the electrical and mechanical elements that contribute to the fulfilment of a given function. It represents a key link in the dependability chain.

Consequently, the type of distribution switchboard must be perfectly adapted to its application. Its design and construction must comply with applicable standards and working practises.

[Schneider Electric]

Распределительные щиты, включая главный распределительный щит низкого напряжения (ГРЩ), играют решающую роль в обеспечении надежности электроустановки. Они должны отвечать требованиям соответствующих стандартов, определяющих конструкцию и порядок изготовления НКУ распределения электроэнергии.

В распределительном щите выполняется прием электроэнергии и ее распределение по отдельным цепям, каждая из которых контролируется и защищается плавкими предохранителями или автоматическими выключателями.
Распределительный щит состоит из функциональных блоков, включающих в себя все электрические и механические элементы, необходимые для выполнения требуемой функции. Распределительный щит представляет собой ключевое звено в цепи обеспечения надежности.

Тип распределительного щита должен соответствовать области применения. Конструкция и изготовление распределительного щита должны удовлетворять требованиям применимых стандартов и учитывать накопленную практику применения.

b. 9 January 1872 Pointe de Bute, Canada

d. 6 March 1949 Orange, New Jersey, USA

[br]

Canadian physicist and electrical engineer responsible for important developments in electronic-circuit technology.

[br]

Colpitts obtained Bachelor's degrees at Mount Allison University, Sackville, New Brunswick, and Harvard in 1894 and 1896, respectively, followed by a Master's degree at Harvard in 1897. After two years as assistant to the professor of physics there, he joined the American Bell Telephone Company. When the Bell Company was reorganized in 1907, he moved to the Western Electric branch of the company in New York as Head of the Physical Laboratories. In 1911 he became a director of the Research Laboratories, and in 1917 he became Assistant Chief Engineer of the company. During this time he invented both the push-pull amplifier and the Colpitts oscillator, both major developments in communications. In 1917, during the First World War, he spent some time in France helping to set up the US Signal Corps Research Laboratories. Afterwards he continued to do much, both technically and as a manager, to place telephone communications on a firm scientific basis, retiring as Vice-President of the Bell Telephone Laboratories in 1937. With the outbreak of the Second World War in 1941 he was recalled from retirement and appointed Director of the Engineering Foundation to work on submarine warfare techniques, particularly echo-ranging.

SUBJECT AREA: Electricity

[br]

b. 27 July 1862 Neisse, Upper Silesia (now Nysa, Poland)

d. 18 January 1921 Berthelsdorf, Silesia

[br]

German electrical engineer, inventor of a transformer for electromotors.

[br]

Ilgner graduated from the Gewerbeakademie (the forerunner of the Technical University) in Berlin. As the representative of an electric manufacturing company in Breslau (now Wroclaw, Poland) from 1897, he was confronted with the fact that there were no appropriate drives for hoisting-engines or rolling-plants in steelworks. Two problems prevented the use of high-capacity electric motors in the mining as well as in the iron and steel industry: the reactions of the motors on the circuit at the peak point of stress concentration; and the complicated handling of the control system which raised the risks regarding safety. Having previously been head of the department of electrical power transmission in Hannover, he was concerned with the development of low-speed direct-current motors powered by gas engines.

It was Harry Ward Leonard's switchgear for direct-current motors (USA, 1891) that permitted sudden and exact changes in the speed and direction of rotation without causing power loss, as demonstrated in the driving of a rolling sidewalk at the Paris World Fair of 1900. Ilgner connected this switchgear to a large and heavy flywheel which accumulated the kinetic energy from the circuit in order to compensate shock loads. With this combination, electric motors did not need special circuits, which were still weak, because they were working continuously and were regulated individually, so that they could be used for driving hoisting-engines in mines, rolling-plants in steelworks or machinery for producing tools and paper. Ilgner thus made a notable advance in the general progress of electrification.

His transformer for hoisting-engines was patented in 1901 and was commercially used inter alia by Siemens \& Halske of Berlin. Their first electrical hoisting-engine for the Zollern II/IV mine in Dortmund gained international reputation at the Düsseldorf exhibition of 1902, and is still preserved in situ in the original machine hall of the mine, which is now a national monument in Germany. Ilgner thereafter worked with several companies to pursue his conception, became a consulting engineer in Vienna and Breslau and had a government post after the First World War in Brussels and Berlin until he retired for health reasons in 1919.

b. 1 March 1880 Kiev, Ukraine

d. 25 January 1963 Willesden, London, England

[br]

Russian engineer and friend of Vladimir Zworykin; Director of Research at EMI, responsible for creating the team that successfully developed the world's first all-electronic television system.

[br]

After his initial engineering education at Kiev Polytechnic, Shoenberg went to London to undertake further studies at the Royal College of Science. In 1905 he returned to Russia and rose to become Chief Engineer of the Russian Wireless Telegraphy Company. He then returned to England, where he was a consultant in charge of the Patent Department and then joint General Manager of the Marconi Wireless Telegraphy Company (see Marconi). In 1929 he joined the Columbia Graphophone Company, but two years later this amalgamated with the Gramophone Company, by then known as His Master's voice (HMV), to form EMI (Electric and Musical Industries), a company in which the Radio Corporation of America (RCA) had a significant shareholding. Appointed Director of the new company's Research Laboratories in 1931, Shoenberg gathered together a team of highly skilled engineers, including Blumlein, Browne, Willans, McGee, Lubszynski, Broadway and White, with the objective of producing an all-electronic television system suitable for public broadcasting. A 150-line system had already been demonstrated using film as the source material; a photoemissive camera tube similar to Zworykin's iconoscope soon followed. With alternate demonstrations of the EMI system and the mechanical system of Baird arranged with the object of selecting a broadcast system for the UK, Shoenberg took the bold decision to aim for a 405-line "high-definition" standard, using interlaced scanning based on an RCA patent and further developed by Blumlein. This was so successful that it was formally adopted as the British standard in 1935 and regular broadcasts, the first in the world, began in 1937. It is a tribute to Shoenberg's vision and the skills of his team that this standard was to remain in use, apart from the war years, until finally superseded in 1985.

b. 18 October 1863 Kimmerghame, Berwickshire, Scotland

d. 19 February 1930 London, England

[br]

Scottish electrical engineer who correctly predicted the development of electronic television.

[br]

After a time at Cargilfield Trinity School, Campbell-Swinton went to Fettes College in Edinburgh from 1878 to 1881 and then spent a year abroad in France. From 1882 until 1887 he was employed at Sir W.G.Armstrong's works in Elswick, Newcastle, following which he set up his own electrical contracting business in London. This he gave up in 1904 to become a consultant. Subsequently he was an engineer with many industrial companies, including the W.T.Henley Telegraph Works Company, Parson Marine Steam Turbine Company and Crompton Parkinson Ltd, of which he became a director. During this time he was involved in electrical and scientific research, being particularly associated with the development of the Parson turbine.

In 1903 he tried to realize distant electric vision by using a Braun oscilloscope tube for the. image display, a second tube being modified to form a synchronously scanned camera, by replacing the fluorescent display screen with a photoconductive target. Although this first attempt at what was, in fact, a vidicon camera proved unsuccessful, he was clearly on the right lines and in 1908 he wrote a letter to Nature with a fairly accurate description of the principles of an all-electronic television system using magnetically deflected cathode ray tubes at the camera and receiver, with the camera target consisting of a mosaic of photoconductive elements that were scanned and discharged line by line by an electron beam. He expanded on his ideas in a lecture to the Roentgen Society, London, in 1911, but it was over twenty years before the required technology had advanced sufficiently for Shoenberg's team at EMI to produce a working system.

b. 31 May 1845 near Thirsk, Yorkshire, England

d. 15 February 1940 Azerley Chase, Ripon, Yorkshire, England

[br]

English electrical and transport engineer.

[br]

Crompton was the youngest son of a widely travelled diplomat who had retired to the country and become a Whig MP after the Reform Act of 1832. During the Crimean War Crompton's father was in Gibraltar as a commander in the militia. Young Crompton enrolled as a cadet and sailed to Sebastopol, visiting an older brother, and, although only 11 years old, he qualified for the Crimean Medal. Returning to England, he was sent to Harrow, where he showed an aptitude for engineering. In the holidays he made a steam road engine on his father's estate. On leaving school he was commissioned into the Rifle Brigade and spent four years in India, where he worked on a system of steam road haulage to replace bullock trains. Leaving the Army in 1875, Crompton bought a share in an agricultural and general engineering business in Chelmsford, intending to develop his interests in transport. He became involved in the newly developing technology of electric arc lighting and began importing electric lighting equipment made by Gramme in Paris. Crompton soon decided that he could manufacture better equipment himself, and the Chemlsford business was transformed into Crompton \& Co., electrical engineers. After lighting a number of markets and railway stations, Crompton won contracts for lighting the new Law Courts in London, in 1882, and the Ring Theatre in Vienna in 1883. Crompton's interests then broadened to include domestic electrical appliances, especially heating and cooking apparatus, which provided a daytime load when lighting was not required. In 1899 he went to South Africa with the Electrical Engineers Volunteer Corps, providing telegraphs and searchlights in the Boer War. He was appointed Engineer to the new Road Board in 1910, and during the First World War worked for the Government on engineering problems associated with munitions and tanks. He believed strongly in the value of engineering standards, and in 1906 became the first Secretary of the International Electrotechnical Commission.

[br]

Chinese electrical engineer whose work on optical fibres did much to make optical communications a practical reality.

[br]

After the Second World War, Kao moved with his family to Hong Kong, where he went to St Joseph's College. To further his education he then moved to England, taking his "A" Levels at Woolwich Polytechnic. In 1957 he gained a BSc in electrical engineering and then joined Standard Telephones and Cables Laboratory (STL) at Harlow. Following the discovery by others in 1960 of the semiconductor laser, from 1963 Kao worked on the problems of optical communications, in particular that of achieving attenuation in optical cables low enough to make this potentially very high channel capacity form of communication a practical proposition; this problem was solved by suitable cladding of the fibres. In the process he obtained his PhD from University College, London, in 1965. From 1970 until 1974, whilst on leave from STL, he was Professor of Electronics and Department Chairman at the Chinese University of Hong Kong, then in 1982–7 he was Chief Scientist and Director of Engineering with the parent company ITT in the USA. Since 1988 he has been Vice-Chancellor of Hong Kong University.

b. 25 July 1857 Milford, Connecticut, USA

d. 25 October 1934 New York, USA

[br]

American electrical engineer and inventor, a leading innovator in electric propulsion systems for urban transport.

[br]

Graduating from the United States Naval Academy, Annapolis, in 1878, Sprague served at sea and with various shore establishments. In 1883 he resigned from the Navy and obtained employment with the Edison Company; but being convinced that the use of electricity for motive power was as important as that for illumination, in 1884 he founded the Sprague Electric Railway and Motor Company. Sprague began to develop reliable and efficient motors in large sizes, marketing 15 hp (11 kW) examples by 1885. He devised the method of collecting current by using a wooden, spring-loaded rod to press a roller against the underside of an overhead wire. The installation by Sprague in 1888 of a street tramway on a large scale in Richmond, Virginia, was to become the prototype of the universally adopted trolley system with overhead conductor and the beginning of commercial electric traction. Following the success of the Richmond tramway the company equipped sixty-seven other railways before its merger with Edison General Electric in 1890. The Sprague traction motor supported on the axle of electric streetcars and flexibly mounted to the bogie set a pattern that was widely adopted for many years.

Encouraged by successful experiments with multiple-sheave electric elevators, the Sprague Elevator Company was formed and installed the first set of high-speed passenger cars in 1893–4. These effectively displaced hydraulic elevators in larger buildings. From experience with control systems for these, he developed his system of multiple-unit control for electric trains, which other engineers had considered impracticable. In Sprague's system, a master controller situated in the driver's cab operated electrically at a distance the contactors and reversers which controlled the motors distributed down the train. After years of experiment, Sprague's multiple-unit control was put into use for the first time in 1898 by the Chicago South Side Elevated Railway: within fifteen years multiple-unit operation was used worldwide.
