LIGHTNING PROTECTION
Lightning is one of the most beautiful natural phenomena to see & most disastrous one to experience.
Lightning discharge may carry current up to hundreds of kiloamperes (KA). It may cause damage to human
life, structure, electrical as well as electronic equipments. It may also cause fire & disrupt working operations
of any industry. It’s been an electronic era and our dependence on electronics has been increased. One
lightning strike can destroy partially / completely all equipments installed in any establishment. Hence,
protection from such natural disasters from lightning strike is essential.
Lightning Protection System has four basic objectives:
1. To capture lightning strike.
2. Safely routing the lightning discharge current to ground.
3. Provide efficient earthing / grounding path for dissipation of lightning current.
4. Remove secondary effects of lightning like over voltages / surges.
LIGHTNING FORMATION
In normal conditions, atmospheric charges are balanced, but cloud formation creates charge polarization. In
such case, normally lower part of cloud gets negatively charged, inducing the positive charge at the ground
or other elements on ground. Electric field at the atmosphere can reach in kilovolts(KV). Positive charges are
more evident at pointed and metallic objects or well earthed objects & trees. When electric field becomes
high then cloud starts discharging towards ground, which results in downward leader. Similarly, metallic
parts / structure where positive charges are present, starts moving upwards forming an upward leader.
These upward and downward leader when meet may result in lightning discharge to ground. Such high
charged metallic part may struck by lightning. This discharge moves down to earth through most direct path.
Hence, if this path is not controlled then disasters may happen. However, lightning discharges can be both
positive and negative.
EFFECTS OF LIGHTNING
 Thermal Effect – Excessive energy in lightning discharge may cause fire.
 Electrodynamic Effect – Damage to structure.
 Electrical Effect – Equipment may damage. Due to increase in ground potential, surge currents may
damage equipments connected to electrical network.
 Inductive Effects – Due to electromagnetic field, currents may couple to all conductors & may damage
equipments connected to it.
 Effects on living beings – Electrocution, burns or even loss of life & may lead to cardiac arrest also.
Damage due to lightning may be high in terms of loss of life, fire, equipments failure, loss of time, &
production. Hence, protection from direct lightning strike is must.

Standard for ESE Lightning Protection System
Our Lightning Protection System is designed as per NFC 17-102, UNE 21186 & other national standards.
Above standards consider Lightning Protection System in following cases:
 Important monuments / archaeological buildings.
 Structures occupied by large number of people.
 Equipments / machines used for production / working system / hospitals etc.
 High rise buildings.
 Isolated structures.
 Areas with high lightning density.
 Buildings containing flammable material / explosives.
 Buildings / structures which comes under risk index as per standards.
Procedure for risk analysis is also described in above standard & should be followed in selecting & design of
Lightning Protection system. Risk assessment determines the need of lightning protection system & degree
of security / level of protection required.
Level of protection / risk analysis: NFC 17-102 standards have mentioned 4 levels of protection based on
risk of lightning strike on a particular structure as Level I, Level II, Level III & Level IV
Accessing the risk of Lightning Protection System is based on lot of factors, however, it is recommended
to opt Level I protection level.
SABO LIVA ADVANCED ESE LIGHTNING CONDUCTOR
We have developed new Advanced Active Lightning conductor based on Early Streamer Emission (ESE)
technology. The main feature of our ESE air terminal is generation of an upward leader before any other
object within its protection area at correct time. So, when downward leader approaches the ground /
structure, upward leader intercepts the same and route the same to earth. This early discharge of upward
leader is called advance time / advance triggering time or ∆t. This is average gain in upward leader triggering
time compared to a conventional lightning rod. Advance triggering time determines the protection radius of
each terminal. If ∆t is more, then the distance at which downward leader is intercepted increases thus
avoiding strike in wider area.
Results of the same have been obtained in HV Laboratory of METU & CNAS (ILAC-MRA) as per test
procedures of NFC17-102 standards.

SABO LIVA ESE Lightning conductor are also tested in accordance with NFC 17-102 for short circuit test of
100KA from SIGMA HV Lab, temperature test of -40°Cto +120°C for its suitability for all environmental &
climatic conditions, CE certified & marked & carries unique serial number. Our lightning conductor also carry
30 years warranty.
NFC 17-102 has given upper limit value of ∆t as 60µs for calculating protection radius of lightning conductor,
but those found higher in testing are better and provides high safety factor.
Below are details of advance triggering time of various models tested in Laboratory:
Protection Radius
Protection radius of ESE air terminal is related to its height
(h) relative to the surface to be protected, to its efficiency &
selected protected level. Protection radius calculation
formula is:
Rp=√h(2D-h)+∆L(2D+∆L)
Where, Rp (m)=Protection radius at given Height
H(m)= Height of ESE at tip over the horizontal plane
through the furthest point of object to be protected.
D(m) =20 m for Level I
30 m for Level II
45 m for Level III
60 m for Level IV
∆L=Distance to catch lightning in ∆t period =∆t
∆t = Advance triggering time in micro seconds.
Example for calculating protection radius as per above formula.
Value of ∆t for LAPBX 175 obtained is 60µs, ∆L=60m
Assuming Level I protection, D=20m, Height (h) = 5m
Rp=√h(2D-h)+∆L(2D+∆L)
=√5(2x20-5)+60(2x20+60
= 79 m
NFC 17-102-2011 has limited higher value of ∆t as 60µs. Hence, conductors with higher ∆t values should be
considered as 60μs & accordingly their protection radius will be limited.

greater speed to a higher altitude, that intercepts downward lightning leader at such high levels, providing
larger protection coverage radius.
Catalogue - Lightning Protection System
www.saboearth.com 7
Selection & Positioning of ESEAir Terminal
Selection of ESE air terminal should be made considering protection radius desired & risk of lightning strike
i.e., level of protection.
Positioning of ESE air terminal should be done considering:
 Minimum 2m above the highest point of structure including aerials, air conditioning towers, tanks,
dome, parapet, etc.
 Architectural view
 For protecting open areas like sports field, golf courses, swimming pools, campsites, etc. ESE
should be installed over specific places such as lighting masts, poles or any other nearby structure
that allows it to cover the whole area.
For buildings higher then 60m or any other point more
than 120m, protection against lateral lightning strike
should be considered. For such buildings, top 20%
height of the structure should be protected by
installing ESE air terminal at each wall. ESE on each
such wall should be considered having radius of
protection ≥20% height of the building. Also, minimum
4 down conductors interconnected by a ring
conductor along the perimeter should be used &
earthed for such high rise buildings.
Protection of buildings requiring level of protectionI + additional measures
For higher degree of protection more than Level I, apart from using ESE air terminal based on Level I, all
metal parts & reinforced bars of buildings used as down conductors should be connected to ESE / down
conductor at roof level & ground level. Also, ring conductors may be used at roof level & ground level.
For buildings, where lightning strike occurs more often, protection radius of ESE air terminal shall be
considered as 40% lesser than tested considering additional safety factor.

Down Conductor
Function of down conductor is to conduct lightning current from the air terminal to the earth termination
system. They should preferably be placed at the external part of the structure. For a non isolated ESE
system, at least two down conductors should be used. For better current distribution the two paths to ground
should be situated on two different facades, unless unavoidable. For an isolated ESE system, one down
conductor is sufficient.
In case of pylons, mast, chimneys & other metallic structures:
 If structure fulfils the requirement for natural components*, then may be used as first down conductor.
 If structure is isolated it may be used as only down conductor.
 If structure is non isolated, it can be used as one down conductor only if it’s section is 100 sq mm or
more.
*Natural components are external steel structure having minimum 2 mm thickness if it is pipe, resistance of
<0.1Ω, not coated with insulating material with more than 0.1mm coating and cross sectional area of 100
sq.mm. Down conductor should be of minimum 50 sq. mm. copper. It is preferred to use copper strip instead
of copper wire of 8mm dia, as copper strip surface area is higher. 25x2mm or 25x3mm copper strip / tinned
copper strip as down conductor.
Routing of down conductor
Down conductor should be routed through straight & shortest path. Sharp bends or upward sections are
avoided. Bend radii should be 20 cm or more. Bends formed edge wise should be used. They should not be
routed along or through electrical duct or conduits. Routing down conductor through parapet wall or cornices
or obstacles should be avoided.

Kindly check below figure for down conductor bend shapes.
l = length of loop
d=width of loop
Note: d > l/20 for avoiding risk of any dielectric breakdown.
Test Joint
Each down conductor should be provided with test joint to
disconnect the earth termination system for measurements.
These test joints are usually installed at the bottom of down
conductors. When down conductors are installed on metal walls
or when specific down conductor is not provided, test joints are
inserted between the earthing system & metallic part of the
structure. If test joints are installed below the ground level,
inspection pit cover should be provided.
Lightning Event Counter
It is used to get counts of number of times lightning gets discharged to earth through ESE system installed.
It should be installed at most direct down conductor at eye level above the ground. It should be water proof

EQUIPOTENTIALBONDING
During the discharge of lightning current from lightning
air terminal to earth, dangerous spark may occur
between Lightning protection system & following
components:
• Metal installations
• Internal systems
• External conductive parts & lines connected to the structure
These sparks may be avoided by bonding / interconnecting lightning protection system with structural
metallic parts, metal installations, internal systems, external conductive parts & lines connected to
structures. When lightning equipotential bonding is established to internal systems, part of lightning current
may flow into such systems which should be protected through surge protection devices. Hence, surge
protection device should also be bonded lightning protection earthing.
Lightning equipotential bonding for an isolated ESE system shall be established at ground level only.
For non isolated ESE lightning protection system, Lightning equipotential bonding can be done at following
places:
• Ground Level / Basement – Bonding conductors should be connected to a bonding bus bar, which
should be connected to earth termination system. Such bus bar should be installed at intervals of
approx 20 mtr along the length of building for keeping bonding conductors as short as possible.
• In cases where insulation requirements are not fulfilled, all metallic conductors / water pipe electrical
equipments / data or power cable should be kept at a distance of 2 m or more from down conductor &
gas connection should be more then 5 m away from down conductor. For soils with resistivity greater
then 500 Ω-m the minimum distance between earthing / down conductor and electrical conduit /
metal should be kept as 5m.
16 sq.mm. copper wire should be the minimum cross section area of bonding conductor for connecting
external metallic parts & bonding bus bar to earth termination / earthing system & 6 sq.mm. copper wire for
internal metallic part / installations to bus bar.
For external conductive parts, lightning equipotential bonding shall be made at the entry point of that part
into the structure. Equipotential bonding may also be achieved by Isolating Spark gap surge protection
devices.
If internal equipments are screened or located in a metallic conduit, then such metallic conduit should be
bonded with equipotential bas bar.
If internal equipments are not screened / located inside
metal conduits, then they shall be bonded via suitable
SPD's. In TN systems, PE & PEN conductors shall be
bonded to ESE system directly with a surge protection
device
Earth Termination System
Earthing Should be provided at each down conductor. Minimum 2 to 3 electrodes are used for each down
conductor. Certain contact surface with soil should be assured in order to dissipiate lightning current in a
short time. For lightning protection system, copper bonded earth rod of 3 mtr length & of cross sectional
area ≥ down conductor size (preferably between 12 mm dia to 17.2mm ) is used with minimum copper
bonding thickness of 250 microns. Spacing between 2 electrodes should be kept as minimum 3m & joined
by copper strip of same size as down conductor.
Earth resistance for lightning protection should be kept <10Ω.
Catalogue - Lightning Protection System
www.saboearth.com 11
Earth resistance enhancement compounds (non-corrosive
& high conductive) SABO-EREC shall also be used along
with earth electrodes for getting low earth resistance values
per earth pit as well as for better dissipation of lightning
discharge and fault currents.
Earth electrodes should be laid horizontally below 0.5m in
case of hard soils / places where vertical driving of rods is
difficult.

Specifications:
 AtTop: 260 mm
 At Bottom : 345 mm
 Height : 275mm
Special measures
An aerial on the roof of a building increases the lightning stroke probability and is the first vulnerable element
likely to receive the lightning discharge. The aerial support mast should be connected directly or through a
Surge Protection Device or an isolated spark gap to the lightning protection system with a suitable conductor,
unless the antenna is outside the protected area or on another roof. The coaxial cable should be protected
with a surge protective device.
A common support mast may be used under the following conditions:
 the ESEAirTerminal is fixed to the tip of the mast;
 the ESEAirTerminal tip is at least 2 m above the nearest aerial;
 the down-conductor is fixed directly onto the air terminal with a clamp;
 the aerial coaxial cable is routed inside the antenna mast.
In case of a trestle tower, it is preferable to route the coaxial cable inside a metal tube.
Flammable and explosive material storage areas
Tanks containing flammable fluids should be earthed but such earth connection may not provide adequate
protection against atmospheric discharges. A thorough additional survey is therefore necessary. ESE Air
Terminals should be placed at a safe distance of 5m or more from such areas higher than the installations to
be protected. If it is possible down-conductors layout should also be outside such area. When it is not
feasible, special care shall be considered to avoid electrical arc.
Earth termination systems should be oriented opposite to the storage areas.
Religious buildings
Steeples, towers, minarets and belfries are prone to being struck by lightning because of their
prominence.
The main prominence(s) should be protected with ESE Air Terminals connected to the ground by a direct
down- conductor routed along the main tower. When the main prominence (s) is higher than 40 m, it is
recommended that the second specific down- conductor should follow the nave ridge. In case the end of the
nave is fitted with a non-metallic cross or statue then such objects will be provided with an air terminal.
Both ESE System earth termination systems and the electric earthing should be interconnected by an earth
conductor.
Some religious buildings have electric bells. The electrical power supply must be protected against over
voltages using surge protective devices according to NF EN 61643-11 and CLC/TS 61643-12.

  • 3. LIGHTNING PROTECTION Lightning is one of the most beautiful natural phenomena to see & most disastrous one to experience. Lightning discharge may carry current up to hundreds of kiloamperes (KA). It may cause damage to human life, structure, electrical as well as electronic equipments. It may also cause fire & disrupt working operations of any industry. It’s been an electronic era and our dependence on electronics has been increased. One lightning strike can destroy partially / completely all equipments installed in any establishment. Hence, protection from such natural disasters from lightning strike is essential. Lightning Protection System has four basic objectives: 1. To capture lightning strike. 2. Safely routing the lightning discharge current to ground. 3. Provide efficient earthing / grounding path for dissipation of lightning current. 4. Remove secondary effects of lightning like over voltages / surges. LIGHTNING FORMATION In normal conditions, atmospheric charges are balanced, but cloud formation creates charge polarization. In such case, normally lower part of cloud gets negatively charged, inducing the positive charge at the ground or other elements on ground. Electric field at the atmosphere can reach in kilovolts(KV). Positive charges are more evident at pointed and metallic objects or well earthed objects & trees. When electric field becomes high then cloud starts discharging towards ground, which results in downward leader. Similarly, metallic parts / structure where positive charges are present, starts moving upwards forming an upward leader. These upward and downward leader when meet may result in lightning discharge to ground. Such high charged metallic part may struck by lightning. This discharge moves down to earth through most direct path. Hence, if this path is not controlled then disasters may happen. However, lightning discharges can be both positive and negative. EFFECTS OF LIGHTNING  Thermal Effect – Excessive energy in lightning discharge may cause fire.  Electrodynamic Effect – Damage to structure.  Electrical Effect – Equipment may damage. Due to increase in ground potential, surge currents may damage equipments connected to electrical network.  Inductive Effects – Due to electromagnetic field, currents may couple to all conductors & may damage equipments connected to it.  Effects on living beings – Electrocution, burns or even loss of life & may lead to cardiac arrest also. Damage due to lightning may be high in terms of loss of life, fire, equipments failure, loss of time, & production. Hence, protection from direct lightning strike is must. + + + + + + -- --- -- - - + + + + + + ++ + --- ---- + + + + + + + + + + + + - - -- -- -- - + + + + + + ++ + Catalogue - Lightning Protection System www.saboearth.com 3
  • 4. Standard for ESE Lightning Protection System Our Lightning Protection System is designed as per NFC 17-102, UNE 21186 & other national standards. Above standards consider Lightning Protection System in following cases:  Important monuments / archaeological buildings.  Structures occupied by large number of people.  Equipments / machines used for production / working system / hospitals etc.  High rise buildings.  Isolated structures.  Areas with high lightning density.  Buildings containing flammable material / explosives.  Buildings / structures which comes under risk index as per standards. Procedure for risk analysis is also described in above standard & should be followed in selecting & design of Lightning Protection system. Risk assessment determines the need of lightning protection system & degree of security / level of protection required. Level of protection / risk analysis: NFC 17-102 standards have mentioned 4 levels of protection based on risk of lightning strike on a particular structure as Level I, Level II, Level III & Level IV Accessing the risk of Lightning Protection System is based on lot of factors, however, it is recommended to opt Level I protection level. SABO LIVA ADVANCED ESE LIGHTNING CONDUCTOR We have developed new Advanced Active Lightning conductor based on Early Streamer Emission (ESE) technology. The main feature of our ESE air terminal is generation of an upward leader before any other object within its protection area at correct time. So, when downward leader approaches the ground / structure, upward leader intercepts the same and route the same to earth. This early discharge of upward leader is called advance time / advance triggering time or ∆t. This is average gain in upward leader triggering time compared to a conventional lightning rod. Advance triggering time determines the protection radius of each terminal. If ∆t is more, then the distance at which downward leader is intercepted increases thus avoiding strike in wider area. Results of the same have been obtained in HV Laboratory of METU & CNAS (ILAC-MRA) as per test procedures of NFC17-102 standards. Level of Protection Level I + Additional measures Level I Level II Level III Level IV Efficiency > 0.98 > 0.95 & ≤ 0.98 > 0.90 & ≤ 0.95 > 0.80 & ≤ 0.90 ≤ 0.80 Level I Level II Level III Level IV PROTECTION LEVEL Higher probability of lightning strike Largerconsequencesincaseof lightningstrike Protected area with level I Protected area with level II Protected area with level III Protected area with level IV Catalogue - Lightning Protection System www.saboearth.com 4
  • 5. SABO LIVA ESE Lightning conductor are also tested in accordance with NFC 17-102 for short circuit test of 100KA from SIGMA HV Lab, temperature test of -40°Cto +120°C for its suitability for all environmental & climatic conditions, CE certified & marked & carries unique serial number. Our lightning conductor also carry 30 years warranty. NFC 17-102 has given upper limit value of ∆t as 60µs for calculating protection radius of lightning conductor, but those found higher in testing are better and provides high safety factor. Below are details of advance triggering time of various models tested in Laboratory: Protection Radius Protection radius of ESE air terminal is related to its height (h) relative to the surface to be protected, to its efficiency & selected protected level. Protection radius calculation formula is: Rp=√h(2D-h)+∆L(2D+∆L) Where, Rp (m)=Protection radius at given Height H(m)= Height of ESE at tip over the horizontal plane through the furthest point of object to be protected. D(m) =20 m for Level I 30 m for Level II 45 m for Level III 60 m for Level IV ∆L=Distance to catch lightning in ∆t period =∆t ∆t = Advance triggering time in micro seconds. Example for calculating protection radius as per above formula. Value of ∆t for LAPBX 175 obtained is 60µs, ∆L=60m Assuming Level I protection, D=20m, Height (h) = 5m Rp=√h(2D-h)+∆L(2D+∆L) =√5(2x20-5)+60(2x20+60 = 79 m NFC 17-102-2011 has limited higher value of ∆t as 60µs. Hence, conductors with higher ∆t values should be considered as 60μs & accordingly their protection radius will be limited.

  • 8. Selection & Positioning of ESEAir Terminal Selection of ESE air terminal should be made considering protection radius desired & risk of lightning strike i.e., level of protection. Positioning of ESE air terminal should be done considering:  Minimum 2m above the highest point of structure including aerials, air conditioning towers, tanks, dome, parapet, etc.  Architectural view  For protecting open areas like sports field, golf courses, swimming pools, campsites, etc. ESE should be installed over specific places such as lighting masts, poles or any other nearby structure that allows it to cover the whole area. For buildings higher then 60m or any other point more than 120m, protection against lateral lightning strike should be considered. For such buildings, top 20% height of the structure should be protected by installing ESE air terminal at each wall. ESE on each such wall should be considered having radius of protection ≥20% height of the building. Also, minimum 4 down conductors interconnected by a ring conductor along the perimeter should be used & earthed for such high rise buildings. Protection of buildings requiring level of protectionI + additional measures For higher degree of protection more than Level I, apart from using ESE air terminal based on Level I, all metal parts & reinforced bars of buildings used as down conductors should be connected to ESE / down conductor at roof level & ground level. Also, ring conductors may be used at roof level & ground level. For buildings, where lightning strike occurs more often, protection radius of ESE air terminal shall be considered as 40% lesser than tested considering additional safety factor.

They should preferably be placed at the external part of the structure. For a non isolated ESE system, at least two down conductors should be used. For better current distribution the two paths to ground should be situated on two different facades, unless unavoidable. For an isolated ESE system, one down conductor is sufficient. In case of pylons, mast, chimneys & other metallic structures:  If structure fulfils the requirement for natural components*, then may be used as first down conductor.  If structure is isolated it may be used as only down conductor.  If structure is non isolated, it can be used as one down conductor only if it’s section is 100 sq mm or more. *Natural components are external steel structure having minimum 2 mm thickness if it is pipe, resistance of <0.1Ω, not coated with insulating material with more than 0.1mm coating and cross sectional area of 100 sq.mm. Down conductor should be of minimum 50 sq. mm. copper. It is preferred to use copper strip instead of copper wire of 8mm dia, as copper strip surface area is higher. 25x2mm or 25x3mm copper strip / tinned copper strip as down conductor. Routing of down conductor Down conductor should be routed through straight & shortest path. Sharp bends or upward sections are avoided. Bend radii should be 20 cm or more. Bends formed edge wise should be used. They should not be routed along or through electrical duct or conduits. Routing down conductor through parapet wall or cornices or obstacles should be avoided.

  • 10. Kindly check below figure for down conductor bend shapes. l = length of loop d=width of loop Note: d > l/20 for avoiding risk of any dielectric breakdown. Test Joint Each down conductor should be provided with test joint to disconnect the earth termination system for measurements. These test joints are usually installed at the bottom of down conductors. When down conductors are installed on metal walls or when specific down conductor is not provided, test joints are inserted between the earthing system & metallic part of the structure. If test joints are installed below the ground level, inspection pit cover should be provided. Lightning Event Counter It is used to get counts of number of times lightning gets discharged to earth through ESE system installed. It should be installed at most direct down conductor at eye level above the ground. It should be water proof and weather proof (IP65 / IP67), non resettable and of 6 digits.

  • 11. LIGHNING CONDUCTOR TESTER Our all lightning conductors & testable lightning counter are testable through an external digital tester Model LLCT-D1 EQUIPOTENTIALBONDING During the discharge of lightning current from lightning air terminal to earth, dangerous spark may occur between Lightning protection system & following components: • Metal installations • Internal systems • External conductive parts & lines connected to the structure These sparks may be avoided by bonding / interconnecting lightning protection system with structural metallic parts, metal installations, internal systems, external conductive parts & lines connected to structures. When lightning equipotential bonding is established to internal systems, part of lightning current may flow into such systems which should be protected through surge protection devices. Hence, surge protection device should also be bonded lightning protection earthing. Lightning equipotential bonding for an isolated ESE system shall be established at ground level only. For non isolated ESE lightning protection system, Lightning equipotential bonding can be done at following places: • Ground Level / Basement – Bonding conductors should be connected to a bonding bus bar, which should be connected to earth termination system. Such bus bar should be installed at intervals of approx 20 mtr along the length of building for keeping bonding conductors as short as possible. • In cases where insulation requirements are not fulfilled, all metallic conductors / water pipe electrical equipments / data or power cable should be kept at a distance of 2 m or more from down conductor & gas connection should be more then 5 m away from down conductor. For soils with resistivity greater then 500 Ω-m the minimum distance between earthing / down conductor and electrical conduit / metal should be kept as 5m. 16 sq.mm. copper wire should be the minimum cross section area of bonding conductor for connecting external metallic parts & bonding bus bar to earth termination / earthing system & 6 sq.mm. copper wire for internal metallic part / installations to bus bar. For external conductive parts, lightning equipotential bonding shall be made at the entry point of that part into the structure. Equipotential bonding may also be achieved by Isolating Spark gap surge protection devices. If internal equipments are screened or located in a metallic conduit, then such metallic conduit should be bonded with equipotential bas bar. If internal equipments are not screened / located inside metal conduits, then they shall be bonded via suitable SPD's. In TN systems, PE & PEN conductors shall be bonded to ESE system directly with a surge protection device Earth Termination System Earthing Should be provided at each down conductor. Minimum 2 to 3 electrodes are used for each down conductor. Certain contact surface with soil should be assured in order to dissipiate lightning current in a short time. For lightning protection system, copper bonded earth rod of 3 mtr length & of cross sectional area ≥ down conductor size (preferably between 12 mm dia to 17.2mm ) is used with minimum copper bonding thickness of 250 microns. Spacing between 2 electrodes should be kept as minimum 3m & joined by copper strip of same size as down conductor. Earth resistance for lightning protection should be kept <10Ω. Catalogue - Lightning Protection System www.saboearth.com 11
  • 12. Earth resistance enhancement compounds (non-corrosive & high conductive) SABO-EREC shall also be used along with earth electrodes for getting low earth resistance values per earth pit as well as for better dissipation of lightning discharge and fault currents. Earth electrodes should be laid horizontally below 0.5m in case of hard soils / places where vertical driving of rods is difficult. Earth Pit Cover Features:  Factory built holes for accessing strips/wires easily at two side  Made of heavy – duty polyethylene for extra durability  Resistant materials  Long service life  Green top cap matches the environment  Non breakable for load upto 5000kg Specifications:  AtTop: 260 mm  At Bottom : 345 mm  Height : 275mm Special measures An aerial on the roof of a building increases the lightning stroke probability and is the first vulnerable element likely to receive the lightning discharge. The aerial support mast should be connected directly or through a Surge Protection Device or an isolated spark gap to the lightning protection system with a suitable conductor, unless the antenna is outside the protected area or on another roof. The coaxial cable should be protected with a surge protective device. A common support mast may be used under the following conditions:  the ESEAirTerminal is fixed to the tip of the mast;  the ESEAirTerminal tip is at least 2 m above the nearest aerial;  the down-conductor is fixed directly onto the air terminal with a clamp;  the aerial coaxial cable is routed inside the antenna mast. In case of a trestle tower, it is preferable to route the coaxial cable inside a metal tube. Flammable and explosive material storage areas Tanks containing flammable fluids should be earthed but such earth connection may not provide adequate protection against atmospheric discharges. A thorough additional survey is therefore necessary. ESE Air Terminals should be placed at a safe distance of 5m or more from such areas higher than the installations to be protected. If it is possible down-conductors layout should also be outside such area. When it is not feasible, special care shall be considered to avoid electrical arc. Earth termination systems should be oriented opposite to the storage areas. Religious buildings Steeples, towers, minarets and belfries are prone to being struck by lightning because of their prominence. The main prominence(s) should be protected with ESE Air Terminals connected to the ground by a direct down- conductor routed along the main tower. When the main prominence (s) is higher than 40 m, it is recommended that the second specific down- conductor should follow the nave ridge. In case the end of the nave is fitted with a non-metallic cross or statue then such objects will be provided with an air terminal. Both ESE System earth termination systems and the electric earthing should be interconnected by an earth conductor. Some religious buildings have electric bells. The electrical power supply must be protected against over voltages using surge protective devices according to NF EN 61643-11 and CLC/TS 61643-12.
