An Arcing Fault is the flow of current through
the air between phase conductors or phase
conductors and neutral or ground. Concentrated
radiant energy is released at the point of arcing
an a small amount of time resulting in Extremely
High Temperature.

Equipotential bonding for lightning protection
according IEC 61024-1 and IEC 61312-1 IEC62305
  • The 100 of lightning energy breaks down as
    follows
  • a) 50 of the lightning current will flow
    through the ground
  • b) 50 of the lightning current will flow over
    the connected metal parts out of the
    building
  • about 10 to the water pipe (metal)
  • about 10 to the gas pipe (metal)
  • about 10 to the oil pipe (metal tank)
  • about 10 to the sewage pipe
  • about 10 to the power suppliers incoming feed
  • max. 5 or 5 kA shared across all data lines

Copper Cladded Conductor For Electrical
Installation
The Copper Clad Steel Grounding Conductor is made
up of steel with the coating of 99.99 pure
copper. These conductors/ wires or strands are
equipped with the strength of steel with the
conductivity and copper with the better corrosion
resistance property. The concentric copper
cladding is metallurgic ally bonded to a steel
core through a continuous, solid cladding
process using pressure rolling for primary
bonding. The copper cladding thickness remains
constant surrounding steel. We use different
steel grades for the steel core result in Dead
Soft Annealed, High strength and Extra High
Strength Characteristics.  The Copper Clad Steel
Wire yields a composite conductivity of 21, 30
and 40 IACS, and available in Annealed and Hard
drawn. We are delivering products with varied
conductivity and tensile strength as per the
customer need. Further, the wire can be processed
to be silver plated or tinned copper clad steel
wire.

What is Exothermic Welding System?Copper to
Bi-Metal and Alumenium
  • Types of Exothermic Joints
  • Possible to join any bi metal except aluminum
  • Exothermic welding is a process of making
    maintain free highly molecular bonding process is
    superior in performance connection to any known
    mechanical or compression-type surface-to-surface
    contact connector. Exothermic weld connections
    provide current carrying (fusing) capacity equal
    to that of the conductor and will not deteriorate
    with age.
  • It offers Electrical connections between two or
    more copper to copper and copper to steel
    conductors.
  • Highly portable method as it does not require
    any external power source or heat source, so it
    can be done almost anywhere.
  • It provides strong permanent molecular bond
    among metallic conductors that cannot loosen and
    further will not deteriorate with age.
  • Connection does not corrode with time and it
    offers permanent conductivity.

    (provided by OMV i.e. Ng 8),
  • Danger for people,
  • Occupation coefficient of structure,
  • Relative location of site,
  • Fire Risk,
  • Associated services,

PASSIVE PROTECTION SYSTEM
45
The Simple Rod air terminal is composed
from a metallic rod with 2 to 8 m height
dominating the structure to protect, and linked
to 2 down conductors minimum, and 2 earthing
systems. The protection radius ensured by this
air terminal which is limited to 30 m more or
less (Protection level IV, height 60 m),
especially dedicated to the protection of small
structures or areas like towers, chimneys, tanks,
water tower, antenna masts The EN 62305-3
standard describes the installation procedure for
these air terminals. 13 Simple Rods, 13 down
conductors, and 13 earthing systems are necessary
to ensure the protection below
46
The meshed cage protection is
composed from a meshing in roof surface and in
the front face around the building. Surrounding
the roof surface, and on high points, capture
points are positioned. A conductors network is
placed at the outer perimeter of the roof. This
network is completed by transverse conductors.
The size of the meshing is 5 to meters, and
depends on the efficiency needed for the
protection. On the front face of the building,
the down conductors are linked at the top to the
meshing of the roof. And, down, to specific
earthing systems. The distance between two
conductors is 10 to 25 meters, and depend on the
efficiency needed for the protection. The EN
62305-3 describes the installation procedure for
this method. Generally, this method is heavy and
expensive, due to the complexity of the
structures to protect. 26 capture points, 26 down
conductors and a grounded loop earthing system
are necessaries to ensure the protection of the
structure here below
47
The catenary wires protection is a
method closed to the meshed cage principle,
because it is constituted with meshing of the
conductors far from the structure to protect, to
avoid any contact with lightning
current. Catenary wires are located over the
structure to protect, connected to down
conductors and specific earthing systems. The
width of the meshing and distance between the
down conductors must respect the same rules as
for the meshed cage. The EN 62305-3 describes the
installation procedure for this
method. Generally, this method is heavy and
expensive, due to the complexity of the
structures to protect.
48
The ESE air terminal is a
terminal which enables to generate artificially
an upward leader earlier than a simple rod, with
an ionization system, in order to establish a
special impact on its point. The capture of the
lightning strike being faster than a simple rod,
this technology enables to benefit from larger
protection areas, ensuring protection for large
dimensions structures. The generated protection
radius depends on the early streamer emission
value of the air terminal (?t in µs), its height,
and the efficiency of the protection. The
protection radius ensured by this type of air
terminal is 120 m (Protection level IV, height
60 m , early streamer emission time 60µs) The NFC
17-102 standard describes the installation
procedure for this type of air terminal. The
installation of this type of air terminal is easy
and cheaper than other technologies. It can
protect whole buildings with one E.S.E. air
terminal. It enables the protection of a
structure and its environment, the protection of
opened areas and well integrate in the
architecture of a structure without aesthetic
alteration. 1 ESE, 2 down conductors and 2
earthing systems are necessary to ensure the
protection below
