(Main)Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c. - Equipment for testing, measuring or monitoring of protective measures - Part 9: Equipment for insulation fault location in IT systems
Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c. - Equipment for testing, measuring or monitoring of protective measures - Part 9: Equipment for insulation fault location in IT systems
IEC 61557-9:2023 specifies the requirements for the insulation fault location system (IFLS) that localizes insulation faults in any part of the system in unearthed IT AC systems and unearthed IT AC systems with galvanically connected DC circuits having nominal voltages up to 1 000 V AC, as well as in unearthed IT DC systems with voltages up to 1 500 V DC, independent of the measuring principle. IEC 61557-9:2023 cancels and replaces the third edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) new terms and definitions on maximum admissible locating AC and DC currents and voltages;
b) the requirements on locating current and locating voltage have been revised;
c) performance requirements have been added;
d) the test requirements for locating current and locating voltage have been revised;
e) the structure of this document has been adapted to that of IEC 61557-1:2019;
f) the limit values under Clause A.2 were adapted to fit the changed test methods in 6.2.3.

Sécurité électrique dans les réseaux de distribution basse tension de 1 000 V c.a. et 1 500 V c.c - Dispositifs de contrôle, de mesure ou de surveillance de mesures de protection - Partie 9: Dispositifs de localisation de défauts d'isolement pour réseaux IT
L'IEC 61557-9:2023 spécifie les exigences applicables aux dispositifs de localisation de défauts d’isolement (DLD) qui, indépendamment du principe de mesure, peuvent localiser les défauts d’isolement des parties de réseaux IT à courant alternatif non mis à la terre et des réseaux IT à courant alternatif non mis à la terre comprenant des circuits à courant continu reliés galvaniquement dont les tensions nominales sont au plus égales à 1 000 V en courant alternatif, et de réseaux IT à courant continu non mis à la terre dont les tensions sont au plus égales à 1 500 V en courant continu. L'IEC 61557-9:2023 annule et remplace la troisième édition parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) ajout de nouveaux termes et de nouvelles définitions sur les courants et tensions, alternatifs et continus, de localisation maximaux admissibles;
b) révision des exigences relatives au courant de localisation et à la tension de localisation;
c) ajout d’exigences de performance;
d) révision des exigences d’essai pour le courant de localisation et la tension de localisation;
e) modification de la structure du présent document pour s’adapter à l’IEC 61557-1:2019;
f) modification des valeurs limites de l’Article A.2 pour s’adapter aux méthodes d’essai modifiées en 6.2.3.
