Annotation of standard text IEC 62153-4-8-ed.2.0 :
IEC 62153-4-8:2018 specifies a test method for determining the capacitive coupling admittance, the capacitive coupling impedance and the coupling capacitance by the use of a triaxial set-up in a similar manner as for the measurement of the transfer impedance (see IEC 62153-4-3). Most cables have negligible capacitive coupling; however, in the case of cables with loose single-braids, the coupling through the holes in the screen shall be determined by the measurement of the capacitive coupling admittance. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) use of the triaxial set-up in a similar manner as for the measurement of the transfer impedance (see IEC 62153-4-3), b) use of vector network analyser instead of capacitance bridge or pulse generator. L’IEC 62153-4-8:2018 specifie une methode d’essai pour la determination de l’admittance de couplage capacitif, l’impedance de couplage capacitif et la capacite de couplage par l’utilisation d’un montage triaxial similaire a celui utilise pour le mesurage de l’impedance de transfert (voir l’IEC 62153-4-3). La plupart des cables presentent un couplage capacitif negligeable. Cependant, dans le cas d’un cable a tressage individuel detendu, le couplage a travers les trous de l’ecran doit etre determine par le mesurage de l’admittance de couplage capacitif. Cette deuxieme edition annule et remplace la premiere edition parue en 2006. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) l’utilisation d’un montage triaxial similaire a celui utilise pour le mesurage de l’impedance de transfert (voir l’IEC 62153-4-3), b) l’utilisation d’un analyseur de reseau vectoriel en lieu et place d’un pont capacitif ou d’un generateur dimpulsions.
