There are two terms that seem to confuse designers.

Estimation of actual maximum kVA demand

In telecommunication , electronics and the electrical power industry , the term demand factor is used to refer to the fractional amount of some quantity being used relative to the maximum amount that could be used by the same system. The demand factor is always less than or equal to one. As the amount of demand is a time dependent quantity so is the demand factor. The demand factor is often implicitly averaged over time when the time period of demand is understood by the context. In electrical engineering the demand factor is taken as a time independent quantity where the numerator is taken as the maximum demand in the specified time period instead of the averaged or instantaneous demand. This is the peak in the load profile divided by the full load of the device. This quantity is relevant when trying to establish the amount of load for which a system should be rated.

General rules of electrical installation design. All individual loads are not necessarily operating at full rated nominal power nor necessarily at the same time. Factors ku and ks allow the determination of the maximum power and apparent-power demands actually required to dimension the installation. In normal operating conditions the power consumption of a load is sometimes less than that indicated as its nominal power rating, a fairly common occurrence that justifies the application of an utilization factor ku in the estimation of realistic values. This factor must be applied to each individual load, with particular attention to electric motors, which are very rarely operated at full load. For socket-outlet circuits, the factors depend entirely on the type of appliances being supplied from the sockets concerned.

There are two terms used in calculating loads in electrical systems that cause designers to get confused. Demand factor is the ratio of the maximum demand of a system, or part of a system, to the total connected load on the system, or part of the system under consideration. Demand factor is always less than one. Diversity factor is the ratio of the sum of the individual maximum demands of the various subdivisions of a system, or part of a system, to the maximum demand of the whole system, or part of the system, under consideration.

Estimation of actual maximum kVA demand

Definition: Diversity factor is defined as the ratio of the sum of the maximum demands of the various part of a system to the coincident maximum demand of the whole system. The maximum demands of the individual consumers of a group do not occur simultaneously. Thus, there is a diversity in the occurrence of the load. Due to this diverse nature of the load, full load power supply to all the consumers at the same time is not required.

Нуматек - богатая фирма, наиболее вероятный победитель аукциона. Ни у кого не вызовет подозрений, если ключ попадет именно к. И что особенно удачно - эту компанию меньше всего можно было заподозрить в том, что она состоит в сговоре с американским правительством. Токуген Нуматака воплощал старую Японию, его девиз - Лучше смерть, чем бесчестье. Он ненавидел американцев.

После каждой из них следовал один и тот же ответ: ИЗВИНИТЕ. ОТКЛЮЧЕНИЕ НЕВОЗМОЖНО Сьюзан охватил озноб. Отключение невозможно. Но. Увы, она уже знала ответ. Так вот какова месть Танкадо. Уничтожение ТРАНСТЕКСТА.

Ведь если кто и может справиться с возникшей опасностью, да еще без посторонней помощи, так это Тревор Стратмор. Он обладал сверхъестественной способностью одерживать верх над всеми, кто бросал ему вызов. Шесть месяцев назад, когда Фонд электронных границ обнародовал информацию о том, что подводная лодка АНБ прослушивает подводные телефонные кабели, Стратмор организовал утечку информации о том, что эта подводная лодка на самом деле занимается незаконным сбросом токсичных отходов. ФЭГ и экологи так и не смогли установить, какая из двух версий соответствует истине, и средства массовой информации в конце концов устали от всей этой истории и перешли к другим темам. Каждый шаг Стратмора был рассчитан самым тщательным образом. Строя свои планы, Стратмор целиком полагался на собственный компьютер.

Но я слышу какие-то звуки. Далекий голос… - Дэвид. Он почувствовал болезненное жжение в боку. Мое тело мне больше не принадлежит. И все же он слышал чей-то голос, зовущий .
