utilisation of calorific value
Calorific value is the heat per unit mass produced by complete combustion of a given substance. Calorific values are used to express the energy values of fuels; usually these are expressed in megajoules per kilogram. They are also used to measure the energy content of foodstuffs; i.e. the energy produced when the food is oxidized in the body. The units here are kilojoules per gram. Calorific values are measured using a bomb calorimeter (apparatus consisting of a strong container in which the sample is sealed with excess oxygen and ignited electrically. The heat of combustion at constant volume can be calculated from the resulting rise in temperature). (Source: DICCHE)

2 tension de référence d'un parafoudre
классификационное напряжение ОПН
Uкл
Максимальное (амплитудное) значение напряжения промышленной частоты, деленное на √2, которое должно быть приложено к ОПН для получения классификационного тока. Классификационное напряжение многоэлементного ОПН определяется как сумма классификационных напряжений отдельных элементов.
[ ГОСТ Р 52725-2007]EN
reference voltage of an arrester, Uref
peak value of power-frequency voltage divided by √2 which is applied to the arrester to obtain the reference current
NOTE 1 The reference voltage of a multi-unit arrester is the sum of the reference voltages of the individual units.
NOTE 2 Measurement of the reference voltage is necessary for the selection of a correct test sample in the operating duty test.

tension de référence d'un parafoudre, Uref
valeur de crête divisée par √2 de la tension à fréquence industrielle qui est appliquée aux bornes du parafoudre pour que celui-ci soit parcouru par le courant de référence.
NOTE 1 La tension de référence d'un parafoudre à plusieurs éléments est la somme des tensions de référence des éléments séparés.
NOTE 2 La mesure de la tension de référence est nécessaire au choix d'un échantillon d'essai convenable dans l'essai de fonctionnement.
