LIGHTNING PROTECTION SYSTEM COMPONENTS (LPSC) –

Part 3: Requirements for isolating spark gaps (ISG)

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 62561-3 has been prepared by IEC technical committee: Lightning
protection.
The text of this standard is based on the following documents:
FDIS Report on voting
81/418/FDIS 81/424A/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The content of this part of IEC 62561 is taken from the European Standard EN 50164-3.

A list of all the parts in the IEC 62561 series, published under the general title Lightning
protection system components (LPSC), can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
This part of IEC 62561 deals with the requirements and tests for isolating spark gaps (ISG)
used for the installation of a lightning protection system (LPS) designed and implemented

LIGHTNING PROTECTION SYSTEM COMPONENTS (LPSC) –

Part 3: Requirements for isolating spark gaps (ISG)



1 Scope
This part of IEC 62561 specifies the requirements and tests for isolating spark gaps (ISG) for
lightning protection systems.
ISGs can be used to indirectly bond a lightning protection system to other nearby metalwork
where a direct bond is not permissible for functional reasons.
Typical applications include the connection to:
• earth termination systems of power installations;
• earth termination systems of telecommunication systems;
• auxiliary earth electrodes of voltage-operated, earth fault circuit breakers;
• rail earth electrode of AC and DC railways;
• measuring earth electrodes for laboratories;
• installations with cathodic protection and stray current systems;
• service entry masts for low-voltage overhead cables;
• bypassing insulated flanges and insulated couplings of pipelines.
This standard does not cover applications where follow currents occur.
NOTE Lightning protection system components (LPSC) can also be suitable for use in hazardous conditions such
as fire and explosive atmosphere. Due regard will be taken of the extra requirements necessary for the
components to be installe
