measuring transducer (with electrical output)
device intended to transform, with a specified accuracy and according to a given law, the measurand, or a quantity already transformed therefrom, into an electrical quantity
NOTE 1 – If the input quantity is electrical, the input and output quantities may not be of the same kind, for example, a voltage and a current.
NOTE 2 – In certain instances, measuring transducers also have a specific name in respect of their function, (for example, amplifier, converter, transformer, frequency transducer, etc.).

transducteur de mesure (à sortie électrique)
dispositif destiné à transformer, avec une précision spécifiée et suivant une loi déterminée, le mesurande, ou la grandeur déjà transformée à partir du mesurande, en une grandeur électrique
NOTE 1 – Si la grandeur d'entrée est électrique, les grandeurs d'entrée et de sortie peuvent ne pas être de même nature, par exemple une tension et un courant.
NOTE 2 – Dans certains cas, les transducteurs de mesure ont également compte tenu de leur fonction, une dénomination spécifique, (par exemple, amplificateur, convertisseur, transformateur, transducteur de fréquence, etc.).

основная частота
Частота в спектре, полученном путем преобразования Фурье функции времени, относительно которой рассматриваются все частоты спектра.
В случае возможного риска неопределенности при определении основной частоты данная частота должна быть определена с учетом числа полюсов и скорости вращения синхронного генератора (генераторов), питающего систему электроснабжения.

fundamental frequency
frequency in the spectrum obtained from a Fourier transform of a time function, to which all the frequencies of the spectrum are referred
NOTE In case of any remaining risk of ambiguity, the fundamental frequency may be derived from the number of poles and speed of rotation of the synchronous generator(s) feeding the system
[IEC 61000-4-30, ed. 2.0 (2008-10)]FR
fréquence fondamentale
fréquence du spectre obtenue à partir d’une transformée de Fourier d’une fonction temporelle, servant de référence à toutes les autres fréquences du spectre
NOTE S’il subsiste un risque d’ambiguïté, la fréquence fondamentale peut être déterminée à partir du nombre de pôles et de la vitesse de rotation du ou des générateurs synchrones alimentant le réseau.
