1 токовая погрешность трансформатора тока
токовая погрешность трансформатора тока
Погрешность, которую трансформатор тока вносит в измерение тока, возникающая вследствие того, что действительный коэффициент трансформации не равен номинальному.
Примечание. Токовая погрешность определяется как арифметическая разность между действительным вторичным током и приведенным ко вторичной цепи действительным первичным током, выраженная в процентах приведенного ко вторичной цепи действительного первичного тока.

current error
the error which a current transformer introduces into the measurement of a current and which arises from the fact that the actual transformation ratio is not equal to the rated transformation ratio
[IEV number 321-01-21]FR
erreur de courant
erreur de rapport (d'un transformateur de courant)
erreur qu'un transformateur de courant introduit dans la mesure d'un courant et qui provient de ce que le rapport de transformation n'est pas égal au rapport de transformation assigné

2 трансформатор тока для защиты
трансформатор тока для защиты
Трансформатор тока, предназначенный для передачи сигнала измерительной информации на устройства защиты и управления.

protective current transformer
a current transformer intended to transmit an information signal to protective and control devices
NOTE – The accuracy class of a protective current transformer is designated by its class index followed by the letter P (standing for "Protection"). The class index gives the limit of the absolute value of composite error at the rated accuracy limit primary current for the class concerned, as a percentage of this current.
[IEV number 321-02-19]FR
transformateur de courant pour protection
transformateur de courant destiné à transmettre un signal d'information à des dispositifs de protection ou de commande
NOTE – La classe de précision d'un transformateur de courant pour protection est désignée par son indice de classe, suivi de la lettre "P" (signifiant "Protection"). L'indice de classe indique la limite supérieure de la valeur absolue de l'erreur composée, au courant limite de précision assigné prescrit pour la classe considérée, en pourcentage de ce courant.

class index (of an energy meter)
number which gives the limits of the absolute value of the permissible relative error, expressed in percent, within a specified range of values for the current, for unity power factor (and in the case of polyphase meters with balanced loads) when the meter is tested under reference conditions (including the permitted tolerances on the reference values)

indice de classe (d'un compteur d'énergie)
nombre qui donne les limites de la valeur absolue de l’erreur relative admissible, exprimée en pourcent, dans une plage spécifiée de valeurs du courant, pour le facteur de puissance égal à l’unité (et dans le cas des compteurs polyphasés avec charges équilibrées), lorsque le compteur est essayé dans les conditions de référence (y compris les tolérances permises sur les valeurs de référence)
