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


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



9/76

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

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.

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.

ESE lightning conductors



26/76

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

50 mm2 for steel to connect to equipotential

bonding bars installed inside the structure and

connected in turn to the closest point of the

earthing circuit.

Unscreened telecommunication or electrical

conductors should be bonded to the lightningprotection system via surge arresters.

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

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 gain in sparkover time T used to

calculate the radius of protection has been

validated in laboratory conditions by

14CH A PT ER

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

inadvisable.

Stainless steel rods are recommended for

these environments.

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.
