28. IEC 61850 Substation Communication Network Architecture for Efficient
Energy System Automation
High-speed peer-to-peer IEC 61850-8-1 GOOSE and IEC 61850-9-2
sampled values based information-exchange among IEDs in modern
IEC 61850 substations have opened the opportunity for designing
and developing innovative all-digital protection applications. The
transmission reliability and real-time performance of these SVs and
GOOSE messages, over the process-bus network, are critical to
realize these all-digital IEC 61850 substation automation systems
(SASs) protection applications. To address the reliability, availability,
and deterministic delay performance needs of SAS, a novel IEC
61850-9-2 process-bus based substation communication network
(SCN) architecture is proposed in this article. Reliability of the
proposed as well as the traditional process-bus based SCN
architectures is evaluated using the reliability block diagram (RBD)
approach. Network components are modeled, and end-to-end (ETE)
time-delay performance is also evaluated for all-digital protection
applications running on the SCN architectures simulated in the
OPNET modeler platform. The reliability and performance results of
the proposed architecture compared to the traditional architectures
confirmed its highly reliable, fast, and deterministic nature.

36. PASSIVE PROTECTION SYSTEM

37. 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 to ers, hi eys, ta ks, ater to er, a te a asts… The EN 0 -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 :

38. The meshed cage protection is composed from a meshing in roof surface and in the front face around the
uildi g. Surrou di g the roof surfa e, a d o high poi ts, apture poi ts are positio ed. A o du tors’
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 :

39. 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.

40. 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 ge erated prote tio radius depe ds o the early strea er e issio alue of the air ter i al Δt i 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 :

58. 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.

60. 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.
