load shedding
emergency disconnection of customer loads to preserve the power network operation. This removes overloads and arrests consequent frequency decline without disrupting the utility transmission grid.
[IEC 61968-2, ed. 1.0 (2003-11)]
load shedding
When the supplying company receives more demand for electrical power than its generating or transmission or installed capacity can deliver, the company has to resort to rationing of the available electricity to its customers. This act is called load shedding.
Load shedding can also be referred to as Demand Side Management or Load Management

123 instaled power
установленная мощность электроустановки
Сумма номинальных мощностей электрических машин одного вида (например, генераторов, двигателей, трансформаторов), входящих в состав промышленного предприятия (например, электростанции) или электрической установки. Выражается в единицах активной мощности (Вт) или полной мощности (ВА).
Под У. м. энергетической системы (или всех электростанций какой-либо страны) понимают суммарную номинальную активную мощность генераторов электростанций, входящих в состав системы (расположенных на территории страны). У. м. электростанций СССР (1975) – свыше 220 ГВт.

каскадирование
-Параллельные тексты EN-RU
Cascading originates from current-limiting technology.
If limiting breaking/making capacity of a circuit breaker is lower than prospective short-circuit current, it can be installed downstream of a current-limiting circuit breaker so that it can have improved breaking capacity due to current-limiting ability of the upstream circuit breaker.
Cascading technology helps lower cost of downstream switches and accessories.
[Schneider Electric]Принцип каскадирования основан на применении технологии токоограничения.
Если предельная отключающая/включающая способность автоматического выключателя ниже ожидаемого тока короткого замыкания, то его можно установить со стороны нагрузки при условии, что со стороны источника питания установлен токоограничивающий автоматический выключатель. Таким образом, отключающая способность выключателя со стороны нагрузки увеличивается за счет токоограничения выключателя, расположенного со стороны источника питания.Метод каскадирования позволяет применять более дешевые принадлежности и аппараты, включаемые со стороны нагрузки.

резервная защита
Координация по сверхтокам двух устройств для защиты от сверхтоков, соединенных последовательно, когда защитное устройство, расположенное, как правило, но необязательно на входной стороне, осуществляет защиту от сверхтока с помощью или без помощи второго защитного устройства, предотвращая его чрезмерную нагрузку.

This consists of installing an upstream circuit-breaker D1 to help a downstream circuit-breaker D2 to break short-circuit currents greater than its ultimate breaking capacity lcuD2.
This value is marked lcuD2+D1.
Standard IEC 60947-2 recognises cascading between two circuit-breakers.
[Schneider Electric]Резервная защита
Смысл резервной защиты состоит в том, что расположенный выше автоматический выключатель D1 помогает расположенному ниже автоматическому выключателю D2 отключать токи короткого замыкания, превышающие предельную отключающую способность lcuD2.
Это значение обозначают lcuD2+D1.
Координация характеристик двух автоматических выключателей, реализуемая по принципу резервной защиты рассмотрена в стандарте МЭК 60947-2.

127 Churchward, George Jackson
[br]b. 31 January 1857 Stoke Gabriel, Devon, Englandd. 19 December 1933 Swindon, Wiltshire, England[br]English mechanical engineer who developed for the Great Western Railway a range of steam locomotives of the most advanced design of its time.[br]Churchward was articled to the Locomotive Superintendent of the South Devon Railway in 1873, and when the South Devon was absorbed by the Great Western Railway in 1876 he moved to the latter's Swindon works. There he rose by successive promotions to become Works Manager in 1896, and in 1897 Chief Assistant to William Dean, who was Locomotive Carriage and Wagon Superintendent, in which capacity Churchward was allowed extensive freedom of action. Churchward eventually succeeded Dean in 1902: his title changed to Chief Mechanical Engineer in 1916.In locomotive design, Churchward adopted the flat-topped firebox invented by A.J.Belpaire of the Belgian State Railways and added a tapered barrel to improve circulation of water between the barrel and the firebox legs. He designed valves with a longer stroke and a greater lap than usual, to achieve full opening to exhaust. Passenger-train weights had been increasing rapidly, and Churchward produced his first 4–6– 0 express locomotive in 1902. However, he was still developing the details—he had a flair for selecting good engineering practices—and to aid his development work Churchward installed at Swindon in 1904 a stationary testing plant for locomotives. This was the first of its kind in Britain and was based on the work of Professor W.F.M.Goss, who had installed the first such plant at Purdue University, USA, in 1891. For comparison with his own locomotives Churchward obtained from France three 4–4–2 compound locomotives of the type developed by A. de Glehn and G. du Bousquet. He decided against compounding, but he did perpetuate many of the details of the French locomotives, notably the divided drive between the first and second pairs of driving wheels, when he introduced his four-cylinder 4–6–0 (the Star class) in 1907. He built a lone 4–6–2, the Great Bear, in 1908: the wheel arrangement enabled it to have a wide firebox, but the type was not perpetuated because Welsh coal suited narrow grates and 4–6–0 locomotives were adequate for the traffic. After Churchward retired in 1921 his successor, C.B.Collett, was to enlarge the Star class into the Castle class and then the King class, both 4–6–0s, which lasted almost as long as steam locomotives survived in service. In Church ward's time, however, the Great Western Railway was the first in Britain to adopt six-coupled locomotives on a large scale for passenger trains in place of four-coupled locomotives. The 4–6–0 classes, however, were but the most celebrated of a whole range of standard locomotives of advanced design for all types of traffic and shared between them many standardized components, particularly boilers, cylinders and valve gear.[br]Further ReadingH.C.B.Rogers, 1975, G.J.Churchward.
