Phase Measurement Unit
The various features of PMUs are given below as
follows PMUs are Measures 50/60 Hz AC
waveforms (voltage and current) typically at a
rate of 48 samples per cycle. PMUs are then
computed using DFT-like algorithms, and time
stamped with a GPS. The resultant time tagged
PMUs can be transmitted to a local or remote
receiver at rates up to 60 samples per cycle.

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
38
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
39
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
40
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.
41
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

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.
