Low-voltage surge protective devices - Part 01: General Requirements and test methods
IEC 61643-01: 2024 contains the common requirements for all SPDs. This document is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages, hereafter referred to as Surge Protective Devices (SPDs). SPDs are intended to be connected to circuits or equipment rated up to 1 000 V AC (RMS) or 1 500 V DC. Performance and safety requirements, tests and ratings are specified in this document. SPDs contain at least one nonlinear component and are intended to limit surge voltages and divert surge currents. This document, together with IEC 61643-11:— (second edition), cancels and replaces the first edition of IEC 61643-11 published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the first edition of IEC 61643-11: a) Clarification on test application either to a complete SPD, to a "mode of protection", or to a complete "SPD assembly"; b) Additional measurement of voltage protection level on "combined modes of protection" between live conductors and PE (see new Annex F); c) Additional duty test for T1 SPD and T2 SPD with follow current to check for increased follow current at lower impulse current amplitude (see 9.3.5.5); d) Modified and amended short circuit current test requirements to better cover up-to-date internal SPD disconnector technologies (see 9.3.6.3); e) Improved dielectric test requirements for the SPD’s main circuits and added dielectric test requirements for "electrically separated circuits" (see 9.3.7 and 9.3.8); f) Additional clearance requirements for "electrically separated circuits" (see 9.4.4); g) Additional information and details for SPDs for DC installations.
Überspannungsschutzgeräte für Niederspannung - Teil 1: Allgemeine Anforderungen und Prüfverfahren
Parafoudres basse tension - Partie 01: Exigences générales et méthodes d’essai
L'IEC 61643-01:2024 contient les exigences communes à tous les SPD. Le présent document est applicable aux dispositifs de protection contre les effets indirects et directs de la foudre ou contre les surtensions transitoires, ci-après dénommés parafoudres (SPD). Les parafoudres sont destinés à être connectés à des circuits ou à des équipements de tension assignée allant jusqu’à 1 000 V efficaces en courant alternatif ou 1 500 V en courant continu. Les exigences de performance et de sécurité, les essais et les valeurs assignées sont spécifiés dans le présent document. Les parafoudres comportent au moins un composant non linéaire et sont utilisés pour limiter les surtensions et écouler les courants de foudre. Le présent document, conjointement avec l’IEC 61643-11:— (deuxième édition), annule et remplace la première édition de l’IEC 61643-11 parue en 2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures importantes suivantes par rapport à la première édition de l’IEC 61643-11: a) clarification de l’application des essais soit à un parafoudre complet, soit à un "mode de protection", soit à un "jeu de parafoudre" complet; b) ajout d’une mesure du niveau de protection en tension sur les "modes de protection combinés" entre les conducteurs actifs et le PE (voir la nouvelle Annexe F); c) ajout d’un essai de fonctionnement pour les parafoudres T1 et T2 avec courant de suite pour vérifier l’augmentation du courant de suite à une amplitude de courant de choc plus faible (voir 9.3.5.5); d) modification des exigences relatives à l’essai de comportement vis-à-vis des courants de court-circuit, afin de mieux couvrir les technologies modernes de déconnecteurs internes de parafoudre (voir 9.3.6.3); e) amélioration des exigences relatives à l’essai diélectrique pour les circuits principaux d’un parafoudre et ajout d’exigences relatives à l’essai diélectrique pour les "circuits électriquement séparés" (voir 9.3.7 et 9.3.8); f) ajout d’exigences en matière de distance d’isolement pour les "circuits électriquement séparés" (voir 9.4.4); g) ajout d’informations et de détails concernant les parafoudres pour les installations à courant continu.
