à dispositif d’amorçage

D : Blitzschutz – Blitzableitersysteme mit Startvorrichtung

Officially approved French standard

On the decision of the Managing Director of AFNOR le 17th August 2011,

with effect from 17th September 2011.

Intended to replace officially approved standard NF C 17-102 of july 1995

which remains in effect until September 2012.

Correspondence There is no equivalent IEC or CENELEC document.

Analysis This document describes the main dispositions in order to insure the

protection of structures, buildings and open areas against direct lightning

impact by early streamer emission protection system. Many tests on ESE

are detailed and specific installation rules are introduced to ensure

protection efficiency.

Descriptors Structures, building, open areas, lightning protection, protection device,

air terminal, installation, design, down conductor, earthing, equipotential

bonding, verification, periodic inspection, maintenance.

Modifications Previous edition of the standard has been upgraded to introduce more

tests and also include new requirements both for product selection and

installation rules.

FOREWORD

There is no international standard or specific European standard about early streamer emission

lightning protection systems

This document is intended to replace the 1995 edition of the NF C 17-102, with its second

printing in 2009.

This document specifies requirements for design, in the present state of knowledge and

technology, protection against lightning of structures (buildings, fixtures, etc.) and open areas

(storage areas, rest areas or sports, etc.) by early streamer emission lightning protection

systems and provides guidance on how to achieve this protection.

Installations for protection against lightning designed and made according to this document,

may not, like everything about the natural elements, ensure the absolute protection of

structures, people or objects; however, the application of this document must reduce

significantly the risk of damage due to lightning on protected structures.

The provisions stated in this document are minimum requirements to ensure statistically an

effective protection.

This new edition is a complete revision of the standard following the publication of the European

standard series EN 62305 and more particularly to the EN 62305-3 giving the requirements for

protection of structures against lightning

However, the EN 62305 series is not dealing with early streamer emission technology, the

revision of the NF C 17-102 appeared essential to provide the design requirements of an early

streamer emission air terminal and those for implementing the ESE lightning protection system.

In order to have no conflict with the European standard series, this document makes no

reference to it, but repeats the necessary arrangements for the design and creation of the

lightning protection system.

The UTE has established the following dates:

- Date on which the previous national standard will be canceled: September 2012;

- Date of cessation of presumption of conformity of products manufactured under the

superseded standard: September 2012.

This document was approved June 28, 2011 by the Commission UF81, Protection against

lightning.

摘要：

NF C 17-102 是2011年发布的法国标准，专门针对采用电子流辐射技术的早期避雷系统（ESE）在防雷保护中的设计与应用。该标准详细规定了此类主动式避雷装置的性能要求、测试方法及安装规范，旨在通过提前触发上行先导放电，更有效地拦截雷击，从而保护建筑物及其内部设备免受直接雷击损害。与传统的富兰克林避雷针相比，ESE系统通常宣称具有更大的保护半径，而 NF C 17-102 为这类系统的可靠性评估和合规性验证提供了权威依据。对于从事防雷工程设计、施工及验收的专业人员而言，理解该标准是确保防雷方案符合国际技术水平和安全要求的关键。
