The effects of lightning are those of a
high-strength impulse current that propagates
initially in a gaseous environment(the atmosphere), and then in a solid, more or
less conductive medium (the ground):
visual effects (flash): caused by the
Townsend avalanche mechanism;
acoustic effects: caused by the propagation
of a shock wave (rise in pressure) originating
in the discharge path; this effect is
perceptible up to a range of around 10
kilometers;
thermal effect: heat generated by the Joule
effect in the ionised channel;
electrodynamic effects: these are the
mechanical forces applied to the conductors
placed in a magnetic field created by the
high voltage circulation. They may result in
deformations;
electrochemical effects: these relatively
minor effects are conveyed in the form of
electrolytic decomposition through theapplication of Faradays law;
induction effects: in a variable electroma-
gnetic field, every conductor harnesses
induced current;
effects on a living being (human or
animal): the passage of a transient current
of a certain r.m.s value is sufficient to
incur risks of electrocution by heart attack
or respiratory failure, together with the
risk of burns.

Accidents caused by a direct stroke when the
lightning strikes a building or a specific
zone. This can cause considerable damage,
usually by fire. Protection against this
danger is provided by lightning conductor
systems.
Lightning causes two major types of accidents:
Accidents caused indirectly, as when the
lightning strikes or causes power surges in
power cables or transmission links. Hence
the need to protect the equipment at risk
against the surge voltage and indirect
currents generated.
2 LIGHTNING PROTECTIONCHAP TE R
To protect a structure against direct lightning
strokes, a preferred impact point is selected to
protect the surrounding structure andconduct the flow of the electric current towards
the ground, with minimal impedance on the
path followed by the lightning.Four types of
protection systems meet these requirements.
I- PROTECTION AGAINST DIRECT LIGHTNING STROKE
By protruding upwards from the building, they
are likely to trigger the release of ascending
streamers and thus be selected as impact
points by lightning strokes occurring within the
vicinity of the structure.
This type of protection is especially recommen-
ded for radio stations and antenna masts when
the area requiring protection is relatively small.
A simple rod lightning conductor is made up of:
a rod lightning conductor and its extension
mast
one or two down conductors,
a connection link or test coupling on each
down conductor to check the conductor
earth resistance,
a protecting flat to protect the down
conductor for the last two meters aboveground level,
an equipotential bonding between each
earth and the general earthing circuit of the
structure; this can be disconnected.

During a storm, when the propagation field
conditions are favourable, the Pulsar first
generates an upward leader. This leader from
the Pulsar tip propagates towards the down-
ward leader from the cloud at an average
speed of 1m/s.
The triggering time T(s) is defined as the
mean gain at the sparkover instant (continuous
propagation of the upward leader) obtained
with an ESE lightning conductor compared witha simple rod lightning conductor exposed to
the same conditions. T is measured in the
high-voltage laboratory conditions defined in
Appendix C of the French standard NF C 17-102.
The triggering time instance gain T is
associated with a triggering time distance
gain L.
L = v. T, where:
L (m): gain in lead distance or
sparkover distance.
v (m/s): average speed of the downward
tracer (1m/s).
T (s): gain in sparkover time of theupward leader measured in
laboratory conditions.
PULSAR conductors are especially effective for
the protection of classified industrial sites,
administrative or public buildings, historical
monuments and open-air sites such as sports
grounds.
The early streamer emission concept
2 LIGHTNING PROTECTIONCHAP TE R
These state-of-the-art technologies have been
designed on the basis of a series of patents
registered jointly by HELITA and the FrenchNational Scientific Research Centre (CNRS).
The PULSAR is equipped with an electronic
device which emits a high pulse voltage of
known and controlled frequency and amplitude
enabling the early formation of the upward
leader which is then continuously propagatedtowards the downward leader.
The PULSAR draws its energy from the ambient
electrical field during the storm. After capturing
the lightning stroke, the PULSAR directs it
towards the down conductor to the ground
where it is dissipated.

TV protection
When lightning strikes cables and transmission
lines (H.F. coaxial cables, telecommunication
lines, power cables), a voltage surge ispropagated and may reach equipment in the
surrounding. This voltage surge can also be
generated by induction due to the
electromagnetic radiation of the lightning flash.
This can have many consequences: premature
component ageing, destruction of printed
circuit boards or component plating,
equipment failure, data loss, programs
hanging, line damage, etc.
This is why you need to use surge arresters to
protect equipment liable to be affected by
lightning strikes.
The use of surge arresters is recommended
when there is at least one lightning conductor
on the building. 65 kA calibration is then
recommended.
II- PROTECTION AGAINST INDIRECT LIGHTNING STROKE EFFECTS
10
During a lightning stroke or even as a result of
indirect effects, equipotential bonding defects
can, by differences in potential, generate
sparkover causing particularly destructive
interference currents.
This is why it is an essential part of effective
lightning protection to ensure that a sites
equipotential bonding is effective and in good
condition.
The same applies to interconnections between
metal earthing networks close to sensitive
equipment (telephone exchanges or CPUs).
III- EQUIPOTENTIAL BONDING DEFECTS

The following method is used for risk evaluation:
1 - Expected frequency Nd of direct lightning strikes on a structure
2 - Tolerable frequency Nc of lightning strikes to the structure
11
The French NF C 17-100 and NF C 17-102 standards recommend a preliminary study in three parts:
lightning risk evaluation
protection level selection,
protection device definition.
3 LIGHTNING PROTECTION STUDYCHAP TE R
The yearly average frequency Nd of direct light-
ning to a structure is assessed by the following
equation:
Nd = Ng max. Ae.C1 10-6/yearwhere:
Ng max. = 2 Ng
Ng: mean annual lightning flash density in the
region where the structure is located
(number of lightning strikes/year/km2)
which can be determined by:
consulting the map overleaf (Ng),
using the isokeraunic level Nk:
Ng max =0.04 Nk 1.25, i.e. around Nk/10
Ae: is the equivalent collection area of the
isolated structure (in m2). It is defined as the
ground area having the same annual direct
lightning strike probability as the structure.
The calculation formulae are defined in
Appendix B of the NFC 17-100 and NF C 17-102
standards.
C1: environmental coefficient (defined in table
B2 of the NF C 17-102 standard).
The tolerable frequency is assessed using thefollowing equation:
Nc = 5,5. 103 / C2 x C3 x C4 x C5
where C2 represents the construction type,
C3 represents the structure contents,
C4 represents the structure occupancy,
C5 represents the consequences of a
lightning strike.
The coefficients are defined in tables B5 to B8of the NF C 17-102 standard.
LIGHTNING RISK EVALUATION
The values Nc and Nd are compared.
If Nd Nc, the lightning protection system is not a mandatory requirement.
If Nd > Nc, a protection system offering E 1 -Nc /Nd level of efficiency should be installed.
PROTECTION LEVEL SELECTION
Calculated efficiency Corresponding level of protection Corresponding level of protectionNFC 17-100 December 1997 NFC 17-102 July 1995

0,90< E < 0,95 Level 2 Level 2
0,80 < E < 0,90 Level 3 Level 2
0 < E < 0,80 Level 4 Level 3
The protection level determines the protectionradius of the lightning conductor, the safety
distance (earth interconnection) and the
maintenance period.
If necessary, additional protection measures
aimed at limiting the step voltage, fire
propagation or induced surge voltage effect
can be deployed.

This test procedure consists in evaluating the
triggering time of an early streamer emission
(ESE) lightning conductor compared with a
simple rod lightning conductor (SRC) in high
voltage laboratory conditions. 100 shocks are
applied to the Pulsar in the first configuration,
then to the simple rod conductor in the second
configuration.
4 PROCEDURE FOR EVALUATING THE EFFICIENCY OF AN ESE LIGHTNINGCONDUCTOR ACCORDING TO STANDARD NC F C 17-102 - APPENDIX CCHAP TE R
Natural conditions can be simulated in a
laboratory by superimposing a permanent field
and an impulse field associated with a plate /
ground platform area (H). The tested lightning
conductor is placed on the ground, beneath the
centre of this platform. In the experiment, the
height H = 6 m, and the lightning conductor
height h = 1.5 m.
SIMULATION OF NATURAL CONDITIONS
The permanent field caused by the charge
distribution in the cloud is represented by a DC
voltage of 15 to 20 kv/m (simulating a field of
around 15 to 20 kV/m) applied to the upper
plate.
The impulse field caused by the approach of
the downward leader is simulated with a
negative polarity wave applied to the platform.
The rise time of the wave Tm is 650 s. The
wave gradient, at the significant points is
around 109
V/m/s.
ELECTRICAL CONDITIONS
The volume used for the experiment must be
large enough to allow the ascending discharge
to develop freely:
distance d between upper platform and
tip 2 m,
upper plate diameter distance from upper
plate to ground
The lightning conductors are tested in
sequence in strictly identical geometrical
conditions: same height, same location, same
distance between tip and upper platform.

HELITA has been investing for many years in
research into lightning conductor protection
devices, and is constantly striving to enhancethe performance of its products.
HELITAs ongoing in situ research in France and
abroad has three main objectives:
to enhance the protection models,
to measure in situ the effectiveness of ESE
conductors, already evaluated in laboratory
conditions,
to qualify the dimensioning of the equip-
ment in real-life lightning strike conditions.
OBJECTIVES
Located in the Hautes-Pyrnes department
of France
Keraunic level: 30 days of storms per annum
Purpose of the experiments:
to confirm the triggering time of ESElightning conductors compared to simple
rod conductors
to direct the flow of the lightning currents
captured by the lightning conductors to
low-voltage surge arresters via an appro
priate earthing network.
to test the resistance of the equipment to
lightning shocks and climatological
constraints.
NATURAL LIGHTNING EXPERIMENTAL SITE
Because lightning is a randomly occurring
natural phenomenon, artificial triggering
techniques have been developed to speed up
the research process.
When lightning conditions are prevalent the
triggering technique consists in sending a
rocket with a trailing wire in the direction of the
storm clouds to cause a lightning strike at the
experimental site.
The wire may comprise an insulating section in
order to generate the largest possible number
of lightning strikes for experimental purposes.
Site located at Privat dAllier in Auvergne,
France
Keraunic level: 30
Purpose of the experiments:
to qualify the lightning strike counters and
low-voltage arresters in situ,
to qualify the resistance of the equipment to
triggered lightning strikes.
Site located at Camp Blanding
(Florida/USA)
Keraunic level: 80
Purpose of the experiments:
to confirm the triggering time gain of the ESE
lightning rods compared with single rod
conductors,
to collect data with a view to improving the
protection models.

The width of roof meshes depends on the
required protection level and should not
exceed 15 m. The meshes should be madeas follows:
firstly a closed polygon is formed with a per-
imeter close to the periphery of the roof,
transverse sections are then added as
required to achieve the required mesh density
a conductor should be laid on any roof
ridges
Air terminals are placed vertically at the
highest and most vulnerable points on the
buildings (roof ridges, salient points, edges,corners, etc.).
They are arranged at regular intervals around
the periphery of the roof:
the distance between two 30 cm air
terminals should not exceed 10 m
the distance between two 50 cm air
terminals should not exceed 15 m
strike air terminals not located on the outer
polygon are connected to the polygon:
either by a conductor excluding any upturn
if the air terminals is less than 5 m from
the polygon
or by two conductors in opposite directions
forming a transversal section if the air
terminals is located more than 5 m from
the polygon.

Down conductors should preferably be made
with tin-plated red copper strips, 30 mm wide
and 2 mm thick.
Lightning is a high frequency current that flows
along the periphery of the conductors. For a
like cross-section, a flat conductor has a
greater periphery.
An exception to the above rule is buildings with
aluminium cladding on which a copper down
conductor might generate an electrolytic
coupling phenomenon. Here a 30 x 3 mm
aluminium strip should be used or bimetalconnection.
In some cases where it is impossible to fix the
copper strip, a round 8 mm tin-plated copper
conductor or a 30 x 3 mm flexible tin-plated
copper braid should be used.
OVERVIEW
The path should be planned to take account ofthe location of the earth termination. The path
should be as straight and short as possible
avoiding any sharp bends or upturns.
Curvature radii should be no less than 20 cm.
To divert the down conductor laterally,
30 x 2 mm tin-plated red copper preformed
bends should be used.
The down conductor path should be chosen to
avoid electrical ducts and intersections.
However when crossovers cannot be avoided,
the conduit should be protected inside metalsheathing extending by 1 m on either side of
the crossover. This sheathing should be
connected to the down conductor.
However, in exceptional cases where an outsidedown conductor cannot be installed, the
conductor may run down through a service
duct, provided that this is used for no other
purpose (and subject to agreement with the
safety services and inspection organisations).
The down conductor can also be fixed on a main
concrete wall located behind a curtain wall.
The conductor supports on the curtain walls
should be connected to the down conductor.
PATH
When the face of the parapet wall is less than
or equal to 40 cm, an upward section in the
down conductor is allowed with a maximum
slope of no more than 45. For parapet walls
with an upward section of more than 40 cm,
space should be allowed or a hole drilled to
accommodate a 50 mm minimum diameter
sheath and thereby avoid bypassing.
If this is not possible, supports of the same
height as the wall should be installed to avoid
an upturn.

The lightning conductor is connected to the
down conductor by a connecting clamp that
must be tightly secured on to the mast.
The strip will be secured along the extension
masts by stainless steel clamps. The conductors
can be connected together by coupling strips.
CONNECTION
Whatever the supporting medium the down
conductor must be secured by at least
3 fasteners per linear metre.
Insulators are of no effect in dealing withlightning current. However, insulators are used
to distance the conductors and prevent contact
with easily flammable material (thatch or
wood, for example).
The fastener must be appropriate for the
supporting medium and installed so as not to
impair watertightness and allow the conductor
to expand.
FASTENERS
Each down conductor must be fitted with a test
coupling or connection link to enablemeasurement of the resistance of the earth
and the electrical continuity of the down
conductor.
The test coupling is usually placed about 2 m
above ground level to make it accessible for
inspection purposes only.
To be compliant with standards, the test
coupling should be identified by the words
lightning conductor and the earth symbol.
On metal pylons, framework or cladding, the
test coupling should be placed on the groundin an inspection and earth pit about 1 metre
from the foot of the metal wall to avoid
distorting the resistance measurement of the
earth connection by inevitably measuring the
electrical resistance on the other metallic
networks in the building.
TEST COUPLING
Between the test coupling and the ground,
the strip is protected by a 2-meter galvanised
sheet metal flat fixed by 3 clamps supplied
with the flat.
It is not advisable to use steel protection flats
because of the premature damage liable to be
caused by the electrolytic coupling created
by the steel-copper contact. The protecting
flat can be bent to follow the profile of the
building.

When the regulations require the installation of
a lightning stroke counter, one per lightning
conductor should be installed for simple rod orESE conductors, and 1 on every 4 down
conductors in a meshed cage installation.
The lightning stroke counter should be installed
above the test coupling around 2 meters above
the ground.
The counter is connected as a standard fitting
on the down conductor.
LIGHTNING STROKE COUNTER
SPECIAL CONDITIONS
Each ESE lightning conductor is earthed by at
least one down conductor. An additional downconductor located on another main wall is
required in the following cases:
when the horizontal path projection of the
conductor is greater than the vertical path
projection,
when lightning protection is being installed
on structures taller than 28 metres, or40 metres in the case of industrial chimney
stacks and churches.

Each simple rod lightning conductor is earthed
by at least one down conductor.
When the down path exceeds 35 m a least two
conductors are required for each simple rod
conductor. These down conductors must be
installed on two different main walls.
On churches, 2 down conductors are
systematically installed, one of which follows
the ridge of the nave.
Simple rod lightning conductors
The down conductors are placed on the corners
and salient features of the building in a layout
that should be as symmetrical and regular as
possible.
The average distance between two adjacent
down conductors depends on the required
protection level.
If there is no buried interconnection between
the earths, the down conductors must be
interconnected at ground level.

When lightning current flows through a
conductor, differences in potential appear
between the conductor and nearby metallicnetworks (steel framework, pipes, etc.) inside
or outside the building. Dangerous sparks may
be produced between the two ends of the
resulting open loop.
There are two ways to avoid this problem:
a) establish an interconnection providing an
equipotential bond between the conductorand the metallic networks
b) allow a safety distance between the
conductor and the metallic networks
The safety distance is the distance beyond
which no dangerous sparks can be produced
between the down conductor carrying the
lightning current and nearby metallic networks.
Because it is often difficult to guarantee that
the lightning protection system is sufficiently
isolated during installation or will remain so inthe event of structural changes, on-site work,
etc., equipotential bonding is often preferred.
There are, however, some cases in which
equipotential bonding is not used (e.g. when
there are flammable or explosive piping net-
works). Here, the down conductors are routed
beyond the safety distance s.
Safety distance calculationS (m) = n.ki.L
kmwhere:
"n" is a coefficient determined by the number
of down conductors per ESE lightning conduc-
tor before the contact point considered:
n = 1 for one down conductor,
n = 0,6 for two down conductors,
n = 0,4 for three or more conductors
" ki " is determined by the required protection
level:
ki = 0.1 for protection level 1 (high
protection), for very exposed or strategic
buildings
ki = 0.075 for protection level 2 (reinforced
protection, exposed building)
ki = 0.05 for protection level 3 (standard
protection)
"km" is related to the material situated
between the two loop ends:
km : 1 for air
km = 0.52 for a solid material other than
metal
"L" is the vertical distance between the point
at which proximity is measured and the point
at which the metallic network is earthed or
the nearest equipotential bonding point.
For gas service pipes S = 3 m.
Example: a lightning conductor with a down conductor protects a 20-meter high building with
protection level I.
Question 1 :should an air conditioning extractor located on the roof be interconnected 3 metresfrom the down conductor where L1 = 25 metres?
Answer 1: S1 = 1 x 0,1x 25 = 2,5 m.1
Since the distance (3 metres) between the conductor and the air-conditioning system is greaterthan the safety distance (2.5 metres), there is no need to interconnect this extractor.
Question 2 : Should the computer located in the building 3 metres from the down conductor beinterconnected with the conductor, where L2 = 10 metres?
Answer 2: S2 = 1 x 0,1x 10 = 1,92 m.0,52
Since the distance between the computer and the down conductor (3 metres) is greater than thesafety distance (1.92 metres), there is no need to interconnect this computer.
The software developed by Hlita can be used to quickly calculate the safety distances.

The equipotential bonding of external metallic
networks is an integral part of the outdoor
lightning protection installation just like thedown conductors and their earths.
All conductive metallic networks located
at a distance of less than s (safety distance)
from a conductor should be connected to theconductor by a conductive material with a
like cross-section.
The aerial masts and small posts supporting
electrical power lines should be connected to
the conductor via a mast arrester. Earthingsystems embedded in walls should be
connected to the conductor if terminal
connections have been provided.
EQUIPOTENTIAL BONDING OF EXTERNAL METALLIC NETWORKS
The equipotential bonding of internal metallic
networks is an integral part of the indoor
lightning protection installation.
All conductive metallic networks in the structure(steel frameworks, ducts, sheathing, electrical
raceways or telecommunication cable trays, etc.)
should be connected to the conductor.
This is done by using a conductive material with
a cross-section of at least 16 mm2 for copper or

Each down conductor in a lightning protection
system must be connected to an earth
termination system designed to carry away anddisperse the lightning current.
The earth termination system must fulfil three
inseparable conditions:
The earth termination resistancevalue
French and other international standards, as
well as the technical requirements of a number
of authorities stipulate an earth termination
resistance value of less than 10 ohms.
This value should be measured on the earth
connection isolated from any other conductive
component.
If the resistance value of 10 ohms cannot be
achieved, the earth termination is nonetheless
considered compliant if it is made up of at least
100 m of conductors or electrodes, each
section measuring no more than 20 m.
Current carrying capacity
This is an often overlooked but essential
aspect of lightning conduction. To minimise the
wave impedance value, a parallel configuration
of three electrodes is strongly recommended
instead of just one excessively long electrode.
Equipotential bonding
Standards require the equipotential bonding of
lightning conductor earth termination systems
with the existing earthing systems.
Inspection earth pit
The connection parts of an earth termination
system (ducks foot connector, earth rod, test
coupling) can be accessed in an inspection
earth pit.
OVERVIEW
LIGHTNING CONDUCTORS
The minimum earth termination system is
made up of 25 meters of 30 x 2 mm tin-plated
copper strip, split into 3 strands buried in
3 trenches at a depth of 60 to 80 cm dug in a
fan shape like a ducks foot: one end of the
longest strand is connected to the test
coupling, the two other strands being linked
to a special connection known as a duck foots
connector.
Ducks foot connector
When the site topography does not lend itself
to the installation of a ducks foot as described
above, an earth termination system can be
developed using at least 3 copper earth rods
each with a minimum length of 2 m, buried
vertically in the ground; the rods should be
spaced at intervals of about 2m and at a
mandatory distance of 1 m to 1.5 m from the
foundations.
Earth rods
If the soil type is not altogether suitable for a
ducks foot connector, a combination of ducks
foot and earth rods will significantly enhance
protection. In this case, the end of each duck
foot connector strand is connected to an
earth rod.

1 PULSAR EARLY STREAMER EMISSION LIGHTNING CONDUCTORSCH A PT ER
The early streamer emission concept implemen-
ted in the Pulsar lightning conductor delivers a
unique gain in efficiency: anticipating the natural
formation of an upward leader, the Pulsar
generates a leader that propagates rapidly to
capture the lightning stroke and conduct it
towards the ground. Successfully demonstrated
in laboratory conditions, this triggering time,
compared with simple rod lightning conductors,
offers critical extra protection.

For the Pulsar 60, the 60 s limit adopted
for the gain in sparkover time T used to
calculate the radius of protection has been
validated in laboratory conditions by
Gimelec, the French electrical and electronic
equipment manufacturers association.

Steel core specially designed to give the rod
rigidity and flexibility: the outer envelope
has a constant thickness guaranteed alongthe entire length of the rod: perfect
steel/copper contact.
High corrosion resistance in the ground
due to a 250 thickness of electrolytically
plated copper.
All models have chamfered base.
The conical point is machined (neither
heated nor stamped).
Available in two versions, standard and
extendable.
Rods are designed to support manual
and mechanical driving into the ground.
Manual snap tools (BMA 0015 and BMA
0019) should be used to drive in the
standard rods. Strike heads (HFT 0015
and HTF 0019) screwed on to the sleeves
should be used for the extendable rods.
The extendable rods are threaded at each
end to enable connection by brass sleeve
couplings. These are designed to guarantee
the contact at the rod tip with the end of
the preceding rod.
COPPERBOND RODS *
Self-extendable
In some soils rich in chloride (coastal
areas, marshes, former salt lakes, etc.),
the use of steel or copper rods is

15 CONTROL AND MEASUREMENT INSTRUMENTS FOREARTHING INSTALLATIONSCH A PT ER
The High Frequency ground test set ACA 9500
is a self powered and easily carried impedan-
ce analyser that measure automatically the R
( resistance), Z (impedance) and X (Imaginary
impedance) of a ground system or a ground
loop on a bandwidth from 10 Hz to 1 MHz.
This test set permits to improve the present
measurement standards by introducing the
frequency response to a discharge current
impulse. The spectral energy of a lightning
stroke current can reach 1 MHz, so it is impor-
tant to know the capability of a ground sys-
tem to leak off the current these frequencies
for better protection of the equipmentconnected to it.
Derived from the WENNER and SCHLUMBER-
GER methods the ACA 9500 applies a sinusoi-
dal voltage between the ground system ( to
be measured) and an injection stake via a
resistor to measure the current, an auxiliary
stake permits to measure the voltage. It is
the frequency application of the Ohm law.
This new product is improved thanks to his
injected voltage which is superior than the
other similar product. Consequently, measure
are possible and more precise in high resisti-
vity ground. The measure is possible even
with parasite tension or important earth cur-
rent because of the synchronised demodula-
tion used in the ACA 9500.
