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.

PASSIVE PROTECTION SYSTEM
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 :
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 :
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.
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 ¾s , 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 60¾s) 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 :

Copper Clad Steel Solid ROD and Conductor
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.
