Lightning Protection System Components (LPSC) - Part 6: Requirements for Lightning Strike and Surge Counters (LSC)

This part of IEC 62561 specifies the requirements and tests for devices intended to count the
number of lightning strikes based on the current flowing in a conductor. This conductor may
be part of a lightning protection system (LPS) or connected to an SPD installation or other
conductors, which are not intended to conduct a significant portion of lightning currents.
LSCs may also be suitable for use in hazardous atmospheres and there are therefore extra
requirements necessary for the components to be installed in such conditions.

Blitzschutzsystembauteile (LPSC) - Teil 6: Anforderungen an Blitzzähler (LSC)

Composants des systèmes de protection contre la foudre (CSPF) - Partie 6: Exigences pour les compteurs de coups de foudre (LSC)

L'IEC 62561-6:2018 spécifie les exigences et les essais à appliquer aux dispositifs destinés à compter le nombre de coups de foudre conduits à travers un conducteur. Ce conducteur peut faire partie d'un système de protection contre la foudre (SPF) ou être relié à une installation de parafoudre ou à d'autres conducteurs qui ne sont pas destinés à conduire une partie significative des courants de foudre.
Les compteurs de coups de foudre (LSC) peuvent aussi être employés dans des atmosphères dangereuses; des exigences supplémentaires sont donc nécessaires pour installer les composants dans de telles conditions.
Cette deuxième édition annule et remplace la première édition parue en 2011. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) retrait des classifications précédentes et introduction d'une division simple entre les LSC de type I pour la détection des impulsions (détection du courant de foudre direct) et les LSC de type II pour la détection des chocs de foudre, avec des essais appropriés pour chaque type;
b) modification et ajout de termes et définitions;
c) ajout d'une nouvelle Annexe C (logigramme des essais).

Elementi za zaščito pred strelo (LPSC) - 6. del: Zahteve za števce udarov strele (LSC)

Ta del standarda IEC 62561 določa zahteve in preskuse za naprave, predvidene za štetje števila udarov strele na podlagi pretakanja toka v prevodniku. Ta prevodnik je lahko del sistema za zaščito pred strelo (LPS) ali povezan z inštalacijo SPD ali drugimi prevodniki, ki niso predvideni za prevajanje bistvenega deleža tokov strele.
LSC-ji so tudi lahko primerni za uporabo v nevarnih atmosferah in so zato potrebne dodatne zahteve za komponente, ki jih je treba v takšnih pogojih namestiti.

LIGHTNING PROTECTION SYSTEM COMPONENTS (LPSC) –

Part 6: Requirements for lightning strike counters (LSC)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62561-6 has been prepared by IEC technical committee 81:
Lightning protection.
This second edition cancels and replaces the first edition published in 2011. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) removal of previous classification and introduction of a simple division into Type I for
impulses (direct lightning current detection) and Type II for lightning surge current
detection, with appropriate testing for each type;
b) modification and addition of terms and definitions;
c) addition of a new Annex C (tests flow chart).
