The French Standard for Early Streamer Emission (ESE) lightning protection
systems NFC 17-102 (September 2011 Version)
Harmonization with EN 62305 Series

EN 62305 series standard is recognized as a reference in the field of lightning
protection of conventional type. This standard explains how to select, install
and verify conventional systems of protection against lightning.

Since there is no particular reason for the rules systems with passive rods differ
from those governing systems with ESE Lightning Protection systems, NF C
17102, 2011 version has been created to harmonize the two sets of
constraints.

Including stress tests of the previous editions of the NF C 17102 had to be
more severe than passive to ensure proper functioning of ESE Active Lightning
Rod.

Series EN 62305 does not cover ESE Lightning Rod technology devices,
revision of the NF C 17-102 appeared essential to provide the design
requirements of an ESE lightning rod and those of a lightning protection system
that implementing them.

Harmonization with EN 62305 Series Continued

An international working group was formed to create an entirely new standard.
It was important to have international commentary to use this standard as a
basis for all countries already using ESE Lightning Rod Systems or those who
wish to use it. These countries have taken or will take standard NF C 17102
(2011 September version) as a reference to create their own national
standards.

So this new NF C 17102 Edition (Version 2011) is a complete overhaul of the
standard following the publication of the series of European standards EN
62305 and EN 62305-3 particularly giving the requirements for protection of
structures against lightning.

Harmonization with EN 50164 Series

The standard EN 50164 is the standard reference for lightning protection
components for which manufacturers and suppliers must test their lightning
protection components to verify the design and quality. As with the standard
EN 62305, there is no particular reason that the rules of passive lightning
protection components differ from those governing by ESE lightning protection
systems, revision of the NF C 17-102 was created to harmonize the two sets of
constraints. Furthermore, as the series EN 50164 does not address ESE
lightning protection components technology, revision of the NF C 17-102
appeared essential to provide the design requirements and quality for ESE
lightning protection components.
Harmonization with EN 62 305-2

The method of lightning risk analysis of the 62305-2 standard Ed.1 was fully
integrated in Appendix A of the NFC 17-102 standard without any
modification. It will be necessary to update the 17-102 standard to reflect the
Edition 2 of the European standard.

C.2.1 General requirements
| Slide 6

C.2.1.1 Identification and documentation
The ESEAT is identified by the following information indicated on the
product (marking):
- name, logo or trade mark of the manufacturer;
- product reference;
- early streamer emission efficiency : T (in μs);
- serial number.

C.2.1.2 Marking

least the name, logo or trade mark of the manufacturer, the reference of
the product and the serial number. Checked by the tests in § C.3.1.2
(Marking Test).

Highlight Annex C (Requirements and test procedures)

C.2.2 Requirements for early streamer emission.
The early streamer emission of the ESEAT (ΔT) shall be determined according
to the procedures of clause C.3.5 (Early streamer emission tests).
It shall range between 10 μs and 60 μs. If the result of ΔT is lower than 10 μs,
then the air terminal will not be considered as an ESEAT. If the result of ΔT is
higher than 60 μs, then all the calculations will be made considering ΔT = 60 μs.

C.2.3 Electrical requirements
The ESEAT shall be resistant to a lighting impulse of 100 kA (10/350 wave). This
is verified by the tests defined in C.3.5 (Early streamer emission tests).

C.2.4 Mechanical requirements
The parts of the ESEAT through which the lightning current transits shall have a
section compliant NF EN 50164-2 (possible spark gaps used in the design of the
ESEAT are tested during the current withstanding tests and do not require
mechanical requirements).

The parts of the ESEAT that shall capture the lightning shall have dimensional
characteristics compliant with the table below.
Table C.1 – Material, setup and minimum area of the striking point part's body
NOTE 1: coating shall be smooth and continuous and shall not have any flux tarnishing. Minimum
thickness shall be 50 μm.

sulphide atmospheres characteristic of seaside pollution and industrial
pollution. This is checked by carrying out tests described in C.3.

C.2.6 Electromagnetic compatibility

C.2.6.1 Electromagnetic immunity
The ESEATs without an electronic system or for which all components are
passive are not sensitive to the electromagnetic waves of industrial
environments. Thus, no immunity tests are required.
The other ESEATs shall be subjected to testing. These ESEATs shall be
compliant with the NF EN 61000-6-2 immunity for industrial environments
standard for applicable tests.

C.2.6.2 Electromagnetic emission
The ESEATs without an electronic system or for which all components are
passive do not generate any signals outside of stormy conditions. Thus, no
emission tests are required.
ESEATs with electronic circuits shall be compliant with the NF EN 61000-63 emission standard for residential environments.
For ESEATs that meet these conditions but include radio modules, all
requirements described in the RTTE 1999/5/CE directive shall be met.

order ensure the upkeep and maintenance of its product.
This note shall contain at least the following information:
- The operation(s) to be carried out during the visual inspection of the lightning
protection system;
- The operation(s) to be carried out during the full inspection of the lightning
protection system;
- The testing equipment which may be necessary for carrying out product
inspection;

Tests on Pulsar, ABB lightning ESE Air Terminal

These Tests of compliance of the Pulsar ABB Lightning ESE Air Terminal with
the requirements of the NFC 17 102, were conducted under the supervision of
an external certification organism during the summer 2013.

APAVE has been chosen, it is a French well known certification organism.
Its role is to be a third party that certifies the following occurring:
- These are the same lightning rods that are used from the beginning to the end
of the tests.
- Lightning rods are functional at the beginning and end of each test. This was
done using the Pulsar Test Set to certify the proper functioning of electronics.
- The sequence of tests shall follow the procedure described in Annex C.

Compliance with applicable standards of testing implementation methods, were
the responsibility of the different laboratories involved in the process.

For these tests, different laboratories were used, each specializing in their
fields: Environmental, Mechanical, Electrical Test equipped for high current and
equipped for high voltage.
