initiative is world largest rural broad band connectivity project
through optical fiber.
• Under NOFN project, around 6600 blocks of India in around 650
districts shall be connected to 2,50,000 Gram Panchayats of
respective blocks by utilising existing fibre of BSNL, RAILTEL and
POWERGRID. Incremental fibre shall be laid wherever required
• Approx. 6 Lakh Km new incremental fiber to be laid.
• Minimum 100Mbps bandwidth at each Gram Panchayat

Surge Protection in Circuit
1) Safety for Human life/ Building/Equipments:
To save human life from danger of electrical shock or death by blowing a fuse i.e. To provide an
alternative path for the fault current to flow so that it will not endanger the user
To protect buildings, machinery & appliances under fault conditions.
To ensure that all exposed conductive parts do not reach a dangerous potential.
To provide safe path to dissipate lightning and short circuit currents.
To provide stable platform for operation of sensitive electronic equipments i.e. To maintain the
voltage at any part of an electrical system at a known value so as to prevent over current or
excessive voltage on the appliances or equipment .
(2) Over voltage protection:
Lightning, line surges or unintentional contact with higher voltage lines can cause dangerously
high voltages to the electrical distribution system. Earthing provides an alternative path around
the electrical system to minimize damages in the System.
(3) Voltage stabilization:
There are many sources of electricity. Every transformer can be considered a separate source. If
there were not a common reference point for all these voltage sources it would be extremely
difficult to calculate their relationships to each other. The earth is the most omnipresent
conductive surface, and so it was adopted in the very beginnings of electrical distribution
systems as a nearly universal standard for all electric systems.
Factors affecting on Earth resistivity:
(1) Soil Resistivity:
It is the resistance of soil to the passage of electric current. The earth resistance value (ohmic
value) of an earth pit depends on soil resistivity. It is the resistance of the soil to the passage of
electric current.
It varies from soil to soil. It depends on the physical composition of the soil, moisture, dissolved
salts, grain size and distribution, seasonal variation, current magnitude etc.
In depends on the composition of soil, Moisture content, Dissolved salts, grain size and its
distribution, seasonal variation, current magnitude.
(2) Soil Condition:
Different soil conditions give different soil resistivity. Most of the soils are very poor conductors
of electricity when they are completely dry. Soil resistivity is measured in ohm-meters or ohmcm.
Soil plays a significant role in determining the performance of Electrode.
Soil with low resistivity is highly corrosive. If soil is dry then soil resistivity value will be very high.
If soil resistivity is high, earth resistance of electrode will also be high.
(3) Moisture:
Moisture has a great influence on resistivity value of soil. The resistivity of a soil can be
determined by the quantity of water held by the soil and resistivity of the water itself.
Conduction of electricity in soil is through water.
The resistance drops quickly to a more or less steady minimum value of about 15% moisture.
And further increase of moisture level in soil will have little effect on soil resistivity. In many
locations water table goes down in dry weather conditions. Therefore, it is essential to pour
water in and around the earth pit to maintain moisture in dry weather conditions. Moisture
9) Effect of current magnitude:
Soil resistivity in the vicinity of ground electrode may be affected by current flowing from the
electrode into the surrounding soil.
The thermal characteristics and the moisture content of the soil will determine if a current of a
given magnitude and duration will cause significant drying and thus increase the effect of soil
resistivity
Maintain less than one Ohm Resistance from EARTH PIT conductor to a distance of 15 Meters
around the EARTH PIT with another conductor dip on the Earth at least 500 mm deep. Check
Voltage between Earth Pit conductors to Neutral of Mains Supply 220V AC 50 Hz it should be
less than 2.0 Volts.
Maximum allowable Earth resistance:
Major power station= 0.5 Ohm.
Major Sub-stations= 1.0 Ohm
Minor Sub-station = 2 Ohm

Service connection = 4 Ohm

Copper Clad Steel Solid ROD and Conductor
Most Efficient JointProcess
It is efficient and superior to all existing surface –to-surface
mechanical retention connectors.
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.
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.
Fire Accident Due to Lightning
We Want India Safe Practice Earthing and
Protection
Why Accidents happen?
Accidents generally happen due to lack of
maintenance, lack of Supervision, lack of knowledge,
over confidence and negligence. Accidents may also
happen due to one or more of the following reasons:
 Using improper tools
 Improper/non usage of protective devices
 Lack of proper instructions and supervision
 Mental/physical condition of the employee
 Poor Judgment

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.
