    arc-resistant switchgear
    A type of switchgear design which is designed to withstand the effects of an internal arcing fault, without causing harm to personnel who are located in defined areas. It is not intended to withstand these internal arcing fault without possibly causing physical damage to the structure and/or components, but often the physical damage is less with an arc-resistant design.

    There are three classes of protection:
    Type A - eliminates the emission of gases and particles from the front of the switchgear during an internal arcing fault,
    Type B - eliminates the emission of gases and particles from the front and sides of the switchgear during an internal arcing fault,
    Type C - eliminates the emission of gases and particles from the front and sides of the switchgear, from between compartments within the same cell, and between adjacent cells during an internal arcing fault.

    Arc-resistant switchgear has traditionally been metal-clad, but the basic concept could also be applied to other types of switchgear as well.

    If the electric arc occurs inside LV switchgear it generates internal overpressures and results in local overheatings which may cause high mechanical and thermal stresses in the equipment.

    Besides, the involved materials can generate hot decomposition products, gases or fumes, which, due to the overpressure, are almost always ejected to the outside of the enclosure thus jeopardizing the operator safety.

    The European Directive 2006/95/EC states the fundamental safety requirements for low voltage electric materials (from 50 V to 1000 V in alternating current, from 75 V to 1500 V in continuos current) to be put on the market within the European Community.

    Among the essential safety requirements defined by this Directive particular importance is given to the need of taking technical measures to prevent “temperature rises, electric arcs or radiations which may result in hazards” from occurring.

    This aspect has always been highly considered for apparatus, but it has been wrongly neglected for electrical switchgear and only in the last 10-15 years it has been catching on both at Italian as well as at international level.

    Safety for the operator and for the installation in case of arcing inside LV switchgear can be obtained through three different design philosophies:
    1. assemblies mechanically capable of withstanding the electric arc (passive protection)
    2. assemblies equipped with devices limiting the effects of internal arcing (active protection)
    3. assemblies equipped with current limiting circuitbreakers.

    These three solutions (also combined together) have found a remakable development in the industrial field and have been successfully applied by the main manufacturers of LV switchgear and controlgear assemblies.

    As it can be seen hereafter by examining the first two solutions, an “active” protection against arc faults is intrinsecally more complex than a “passive” one.

    This because of the presence of additional electromechanical/ electronic devices5 which limit the arcing effects and which, by their nature, may be subject to faults or not-tripping.

    Дуга, возникшая внутри НКУ, создает внутреннее избыточное давление и вызывает локальный перегрев, что может привести к воздействию на оборудование значительного механического напряжения и перепада температур.

    Кроме того, под воздействием дуги различные материалы разлагаются на продукты, имеющие высокую температуру, в том числе газы и дым, которые почти всегда вырываются из оболочки НКУ под высоким давлением, подвергая опасности оперативный персонал.

    Европейская директива 2006/95/EC определяет основные требования безопасности для низковольтного (от 50 до 1000 В переменного тока и от 75 до 1500 В постоянного тока) оборудования поставляемого на рынок Европейского Сообщества.

    Одно из основных требований безопасности, определяемое данной директивой как наиболее важное, заключается в необходимости предпринять технические меры для предотвращения "подъема температуры, возникновения электрической дуги или излучения", которые могут причинить ущерб.

    Данная проблема всегда учитывалась при создании различных аппаратов, но незаслуженно игнорировалась при разработке электрических комплектных устройств, и только в последние 10-15 лет ей стали уделять должное внимание как в Италии, так и во всем мире.

    При возникновении электрической дуги внутри НКУ безопасность оператора и электроустановки обеспечивается тремя способами:
    1. Конструкция НКУ должна выдерживать механические воздействия, возникающие при горении электрической дуги (пассивная защита).
    2. НКУ должно быть оснащено устройствами, ограничивающими воздействие электрической дуги (активная защита)
    3. НКУ должны быть оснащены токоограничивающими автоматическими выключателями.

    Указанные три способа (применяемые совместно) получили дальнейшее развитие в промышленности и успешно применяются основными изготовителями НКУ распределения и управления.

    Как будет показано далее при рассмотрении первых двух способов, активная защита от дуговых» неисправностей является более сложной, чем пассивная защита.

    Это объясняется необходимостью использования дополнительных электромеханических или электронных устройств, задачей которых является ограничение воздействий дуги и которые сами могут оказаться неисправными и не сработать.

    arc-resistant switchgear
    A type of switchgear design which is designed to withstand the effects of an internal arcing fault, without causing harm to personnel who are located in defined areas. It is not intended to withstand these internal arcing fault without possibly causing physical damage to the structure and/or components, but often the physical damage is less with an arc-resistant design.

    There are three classes of protection:
    Type A - eliminates the emission of gases and particles from the front of the switchgear during an internal arcing fault,
    Type B - eliminates the emission of gases and particles from the front and sides of the switchgear during an internal arcing fault,
    Type C - eliminates the emission of gases and particles from the front and sides of the switchgear, from between compartments within the same cell, and between adjacent cells during an internal arcing fault.

    Arc-resistant switchgear has traditionally been metal-clad, but the basic concept could also be applied to other types of switchgear as well.

    If the electric arc occurs inside LV switchgear it generates internal overpressures and results in local overheatings which may cause high mechanical and thermal stresses in the equipment.

    Besides, the involved materials can generate hot decomposition products, gases or fumes, which, due to the overpressure, are almost always ejected to the outside of the enclosure thus jeopardizing the operator safety.

    The European Directive 2006/95/EC states the fundamental safety requirements for low voltage electric materials (from 50 V to 1000 V in alternating current, from 75 V to 1500 V in continuos current) to be put on the market within the European Community.

    Among the essential safety requirements defined by this Directive particular importance is given to the need of taking technical measures to prevent “temperature rises, electric arcs or radiations which may result in hazards” from occurring.

    This aspect has always been highly considered for apparatus, but it has been wrongly neglected for electrical switchgear and only in the last 10-15 years it has been catching on both at Italian as well as at international level.

    Safety for the operator and for the installation in case of arcing inside LV switchgear can be obtained through three different design philosophies:
    1. assemblies mechanically capable of withstanding the electric arc (passive protection)
    2. assemblies equipped with devices limiting the effects of internal arcing (active protection)
    3. assemblies equipped with current limiting circuitbreakers.

    These three solutions (also combined together) have found a remakable development in the industrial field and have been successfully applied by the main manufacturers of LV switchgear and controlgear assemblies.

    As it can be seen hereafter by examining the first two solutions, an “active” protection against arc faults is intrinsecally more complex than a “passive” one.

    This because of the presence of additional electromechanical/ electronic devices5 which limit the arcing effects and which, by their nature, may be subject to faults or not-tripping.

    SUBJECT AREA: Electricity
    [br]
    b. 17 June 1832 London, England
    d. 4 April 1919 London, England
    [br]
    English chemist and physicist who carried out studies of electrical discharges and cathode rays in rarefied gases, leading to the development of the cathode ray tube; discoverer of the element thallium and the principle of the Crookes radiometer.
    [br]
    Crookes entered the Royal College of Chemistry at the age of 15, and from 1850 to 1854 held the appointment of Assistant at the college. In 1854 he became Superintendent of the Meteorological Department at the Radcliffe Observatory in Oxford. He moved to a post at the College of Science in Chester the following year. Soon after this he inherited a large fortune and set up his own private laboratory in London. There he studied the nature of electrical discharges in gases at low pressure and discovered the dark space (later named after him) that surrounds the negative electrode, or cathode. He also established that the rays produced in the process (subsequently shown by J.J.Thompson to be a stream of electrons) not only travelled in straight lines, but were also capable of producing heat and/or light upon impact with suitable anode materials. Using a variety of new methods to investigate these "cathode" rays, he applied them to the spectral analysis of compounds of selenium and, as a result, in 1861 he discovered the element thallium, finally establishing its atomic weight in 1873. Following his discovery of thallium, he became involved in two main lines of research: the properties of rarified gases, and the investigation of the elements of the "rare earths". It was also during these experiments that he discovered the principle of the Crookes radiometer, a device in which light is converted into rotational motion and which used to be found frequently in the shop windows of English opticians. Also among the fruits of this work were the Crookes tubes and the development of spectacle lenses with differential ranges of radiational absorption. In the 1870s he became interested in spiritualism and acquired a reputation for his studies of psychic phenomena, but at the turn of the century he returned to traditional scientific investigations. In 1892 he wrote about the possibility of wireless telegraphy. His work in the field of radioactivity led to the invention of the spinthariscope, an early type of detector of alpha particles. In 1900 he undertook investigations into uranium which led to the study of scintillation, an important tool in the study of radioactivity.
    While the theoretical basis of his work has not stood the test of time, his material discoveries, observations and investigations of new facts formed a basis on which others such as J.J. Thomson were to develop subatomic theory. His later involvement in the investigation of spiritualism led to much criticism, but could be justified on the basis of a belief in the duty to investigate all phenomena.

  • 12 Davy, Sir Humphry

    [br]
    b. 17 December 1778 Penzance, Cornwall, England
    d. 29 May 1829 Geneva, Switzerland
    [br]
    English chemist, discoverer of the alkali and alkaline earth metals and the halogens, inventor of the miner's safety lamp.
    [br]
    Educated at the Latin School at Penzance and from 1792 at Truro Grammar School, Davy was apprenticed to a surgeon in Penzance. In 1797 he began to teach himself chemistry by reading, among other works, Lavoisier's elementary treatise on chemistry. In 1798 Dr Thomas Beddoes of Bristol engaged him as assistant in setting up his Pneumatic Institution to pioneer the medical application of the newly discovered gases, especially oxygen.
    In 1799 he discovered the anaesthetic properties of nitrous oxide, discovered not long before by the chemist Joseph Priestley. He also noted its intoxicating qualities, on account of which it was dubbed "laughing-gas". Two years later Count Rumford, founder of the Royal Institution in 1800, appointed Davy Assistant Lecturer, and the following year Professor. His lecturing ability soon began to attract large audiences, making science both popular and fashionable.
    Davy was stimulated by Volta's invention of the voltaic pile, or electric battery, to construct one for himself in 1800. That enabled him to embark on the researches into electrochemistry by which is chiefly known. In 1807 he tried decomposing caustic soda and caustic potash, hitherto regarded as elements, by electrolysis and obtained the metals sodium and potassium. He went on to discover the metals barium, strontium, calcium and magnesium by the same means. Next, he turned his attention to chlorine, which was then regarded as an oxide in accordance with Lavoisier's theory that oxygen was the essential component of acids; Davy failed to decompose it, however, even with the aid of electricity and concluded that it was an element, thus disproving Lavoisier's view of the nature of acids. In 1812 Davy published his Elements of Chemical Philosophy, in which he presented his chemical ideas without, however, committing himself to the atomic theory, recently advanced by John Dalton.
    In 1813 Davy engaged Faraday as Assistant, perhaps his greatest service to science. In April 1815 Davy was asked to assist in the development of a miner's lamp which could be safely used in a firedamp (methane) laden atmosphere. The "Davy lamp", which emerged in January 1816, had its flame completely surrounded by a fine wire mesh; George Stephenson's lamp, based on a similar principle, had been introduced into the Northumberland pits several months earlier, and a bitter controversy as to priority of invention ensued, but it was Davy who was awarded the prize for inventing a successful safety lamp.
    In 1824 Davy was the first to suggest the possibility of conferring cathodic protection to the copper bottoms of naval vessels by the use of sacrificial electrodes. Zinc and iron were found to be equally effective in inhibiting corrosion, although the scheme was later abandoned when it was found that ships protected in this way were rapidly fouled by weeds and barnacles.

    b. 22 February 1857 Hamburg, Germany
    d. 1 January 1894 Bonn, Germany
    [br]
    German physicist who was reputedly the first person to transmit and receive radio waves.
    [br]
    At the age of 17 Hertz entered the Gelehrtenschule of the Johaneums in Hamburg, but he left the following year to obtain practical experience for a year with a firm of engineers in Frankfurt am Main. He then spent six months at the Dresden Technical High School, followed by year of military service in Berlin. At this point he decided to switch from engineering to physics, and after a year in Munich he studied physics under Helmholtz at the University of Berlin, gaining his PhD with high honours in 1880. From 1883 to 1885 he was a privat-dozent at Kiel, during which time he studied the electromagnetic theory of James Clerk Maxwell. In 1885 he succeeded to the Chair in Physics at Karlsruhe Technical High School. There, in 1887, he constructed a rudimentary transmitter consisting of two 30 cm (12 in.) rods with metal balls separated by a 7.5 mm (0.3 in.) gap at the inner ends and metallic plates at the outer ends, the whole assembly being mounted at the focus of a large parabolic metal mirror and the two rods being connected to an induction coil. At the other side of his laboratory he placed a 70 cm (27½ in.) diameter wire loop with a similar air gap at the focus of a second metal mirror. When the induction coil was made to create a spark across the transmitter air gap, he found that a spark also occurred at the "receiver". By a series of experiments he was not only able to show that the invisible waves travelled in straight lines and were reflected by the parabolic mirrors, but also that the vibrations could be refracted like visible light and had a similar wavelength. By this first transmission and reception of radio waves he thus confirmed the theoretical predictions made by Maxwell some twenty years earlier. It was probably in his experiments with this apparatus in 1887 that Hertz also observed that the voltage at which a spark was able to jump a gap was significantly reduced by the presence of ultraviolet light. This so-called photoelectric effect was subsequently placed on a theoretical basis by Albert Einstein in 1905. In 1889 he became Professor of Physics at the University of Bonn, where he continued to investigate the nature of electric discharges in gases at low pressure until his death after a long and painful illness. In recognition of his measurement of radio and other waves, the international unit of frequency of an oscillatory wave, the cycle per second, is now universally known as the Hertz.

    [br]
    b. 26 June 1824 Belfast, Ireland (now Northern Ireland)
    d. 17 December 1907 Largs, Scotland
    [br]
    Irish physicist and inventor who contributed to submarine telegraphy and instrumentation.
    [br]
    After education at Glasgow University and Peterhouse, Cambridge, a period of study in France gave Thomson an interest in experimental work and instrumentation. He became Professor of Natural Philosophy at Glasgow in 1846 and retained the position for the rest of his career, establishing the first teaching laboratory in Britain.
    Among his many contributions to science and engineering was his concept, introduced in 1848, of an "absolute" zero of temperature. Following on from the work of Joule, his investigations into the nature of heat led to the first successful liquefaction of gases such as hydrogen and helium, and later to the science of low-temperature physics.
    Cable telegraphy gave an impetus to the scientific measurement of electrical quantities, and for many years Thomson was a member of the British Association Committee formed in 1861 to consider electrical standards and to develop units; these are still in use. Thomson first became Scientific Adviser to the Atlantic Telegraph Company in 1857, sailing on the Agamemnon and Great Eastern during the cable-laying expeditions. He invented a mirror galvanometer and more importantly the siphon recorder, which, used as a very sensitive telegraph receiver, provided a permanent record of signals. He also laid down the design parameters of long submarine cables and discovered that the conductivity of copper was greatly affected by its purity. A major part of the success of the Atlantic cable in 1866 was due to Thomson, who received a knighthood for his contribution.
    Other instruments he designed included a quadrant electrostatic voltmeter to measure high voltages, and his "multi-cellular" instrument for low voltages. They could be used on alternating or direct current and were free from temperature errors. His balances for precision current measurement were widely used in standardizing laboratories.
    Thomson was a prolific writer of scientific papers on subjects across the whole spectrum of physics; between 1855 and 1866 he published some 110 papers, with a total during his life of over 600. In 1892 he was raised to the peerage as Baron Kelvin of Largs. By the time of his death he was looked upon as the "father" of British physics, but despite his outstanding achievements his later years were spent resisting change and progress.

  • 17 Randall, Sir John Turton

    SUBJECT AREA: Medical technology
    [br]
    b. 23 March 1905 Newton-le-Willows, Lancashire, England
    d. 16 June 1984 Edinburgh, Scotland
    [br]
    English physicist and biophysicist, primarily known for the development, with Boot of the cavity magnetron.
    [br]
    Following secondary education at Ashton-inMakerfield Grammar School, Randall entered Manchester University to read physics, gaining a first class BSc in 1925 and his MSc in 1926. From 1926 to 1937 he was a research physicist at the General Electric Company (GEC) laboratories, where he worked on luminescent powders, following which he became Warren Research Fellow of the Royal Society at Birmingham University, studying electronic processes in luminescent solids. With the outbreak of the Second World War he became an honorary member of the university staff and transferred to a group working on the development of centrimetric radar. With Boot he was responsible for the development of the cavity magnetron, which had a major impact on the development of radar.
    When Birmingham resumed its atomic research programme in 1943, Randall became a temporary lecturer at the Cavendish Laboratory in Cambridge. The following year he was appointed Professor of Natural Philosophy at the University of St Andrews, but in 1946 he moved again to the Wheatstone Chair of Physics at King's College, London. There his developing interest in biophysical research led to the setting up of a multi-disciplinary group in 1951 to study connective tissues and other biological components, and in 1950– 5 he was joint Editor of Progress in Biophysics. From 1961 until his retirement in 1970 he was Professor of Biophysics at King's College and for most of that time he was also Chairman of the School of Biological Sciences. In addition, for many years he was honorary Director of the Medical Research Council Biophysics Research Unit.
    After he retired he returned to Edinburgh and continued to study biological problems in the university zoology laboratory.
