81 Ilgner, Karl
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.[br]Bibliography1901, DRP no. 138, 387 1903, "Der elektrische Antrieb von Reversier-Walzenstraßen", Stahl und Eisen 23:769– 71.Further ReadingW.Kroker, "Karl Ilgner", Neue Deutsche Biographie, Vol. X, pp. 134–5.

защита с сокращенной зоной и разрешающим сигналом
Система защиты, использующая телеканал связи, обычно состоящая из дистанционных защит с сокращенной зоной, установленных на каждом конце защищаемого участка, в которой сигнал передается в случае, если одна из указанных защит обнаружит повреждение. Получение сигнала на другом конце обеспечивает отключение, если местная защита с разрешающим сигналом обнаружила повреждение. См.Рисунок 41.

permissive underreach protection
PUP (abbreviation)
permissive underreaching transfer trip protection (US)
PUTT (US) (abbreviation)
protection, generally distance protection, using telecommunication, with underreach protection at each section end and in which a signal is transmitted when a fault is detected by the underreach protection. Receipt of the signal at the other end initiates tripping if other local permissive protection at the other end has detected the fault
See figure 448-5.
[ IEV ref 448-15-11]FR
protection à portée réduite et à autorisation
protection, en général une protection de distance, à liaison de transmission, avec une protection à portée réduite à chaque extrémité de la section, et dans laquelle un signal est transmis lors de la détection d'un défaut par la protection à portée réduite. A l'autre extrémité, la réception de ce signal commande le déclenchement si une autre protection locale à autorisation a détecté le défaut

распределенное производство электроэнергии
Распределенное производство электроэнергии включает в себя небольшие электростанции, расположенные в распределительной сети электроэнергетического предприятия с целью покрытия местной или региональной пиковой нагрузки (на уровне подстанции) или для того, чтобы отказаться от модернизации или строительства дополнительных местных распределительных линий.

distribution companies
Electricity companies responsible for the psysical transportation of electricity from the high-voltage transmission network to the middle- and low-voltage customers distributed generation: a distributed generation system involves small amounts of generation located on a utility's distribution system for the purpose of meeting local or regional (substation level) peak loads and/or displacing the need to build additional (or upgrade) local distribution lines.
