This document provides information on best practices for electrical safety and lightning protection. It discusses maintaining copper-bonded grounding rods, using exothermic welding for joints, surge protection for power and communication ports, and adopting lightning protection standards. The document recommends specific practices adopted by various state police departments in India, including the Delhi, Tamil Nadu, and Maharashtra police. It also presents information on earthing products, fail-proof joints, copper-clad wires, lightning arrestors, and surge protection devices for electrical installations and systems.

25. Copper Bonded Rod Earthing System is an technically
advance solution which is internationally accepted as robust
grounding system:
-Made of high tensile low carbon steel rod that provides
more surface area for current to flow.
-Coated with 99.9% pure electrolytic grade copper for
better conductivity.
-Coated with 250 micron copper for higher corrosion
resistance that improves product life.

26. Maintenance Free Earth Enhancing Compound
The use of Earth Enhancing Compound complying to …IEEE-
080……..plays an important in making grounding system much more
effective
- It retain moisture thus provide smooth path for current to flow
faster.
-Since it has moisture retention properties it does ’t demand regular
watering that makes the grounding system low maintenance.
-The continuous presence of moisture provides stable Ohmic value.
-It does ’t not washes away with time.
-It does not demand continuous presence of water to maintain its
conductivity

Jointing Methods
Air Gaps

28. Most Efficient JointProcess
It is efficient and superior to all existing surface –to-surface
mechanical retention connectors.

29. 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.

30. 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.

An ESE air terminal generates an advance in the upward leader (acceleration in
the upward streamer) when compared with a single point.
Air Terminals equipped with early streamer emission systems are designed with one or
more capture points and a hub which supports the connection to the down conductor.

50. Sources for Extra Current /Voltages from different areas……
 Signal Surges Generation due
direct lightning
 Switching operations of
heavy duty machines like
motors, lifts, AC units,
refrigerator, welding machine
etc.
 Ground Potential Rise
Short Circuit due Wire/ Cables

51. Problems due to Direct or In-Direct Electrical
Installation.

52. Switching actions
Switching actions occur almost everywhere
where work is done with electrical energy.
Especially vulnerable are areas in which large
inductive loads are switched, for example:
• Motors
• Transformers
• Chokes
• Climate control installations
• Welding equipment
• Long light strings
Effects: Overvoltages (surges) on network lines
Cause: High current steepnesses on switching
actions lead to transient surges (overvoltages) on
the mains wiring.

53. Direct strike on a low-voltage overhead line
The preconditions for a direct strike on a low-
voltage overhead line are not the same as for
direct strikes on high-voltage overhead lines.
The fundamental difference is in the proximity
to the building, which permits the conduction of
partial lightning currents.
Effects: Partial lightning currents and voltage
surges in the low-voltage network.
Cause: the amplitude of the lightning impulse
current

54. Place of Use Lightning protection zone concept according to
IEC 61312-1 & IEC 62305
1 Lightning arresters Class 1
to IEC 61643 (also called as Class B)
Requirement class 1 (<4 kV)
2 Surge arresters Class 2
to IEC 61643 (also called as Class C)
Requirement class 2 (<2.5 kV)
3 Surge arresters Class 3

57. 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
• a out % to the power supplier’s i o i g feed
• max. 5% or 5 kA shared across all data lines
50 %

Equipotential bonding for lightning protection according IEC 61024-
1 and IEC 61312-1; IEC62305
In India & Sri Lanka Only Chance is Power Line
Approximately 50 % of Total Lightning Current has
to be diverted to Power lines
