Lightning and Surge Can Travel long distance and Damage Electrical Safety Earthing,Lightning and Surge Protection
Future Power Generation and Utilities No Boundaries
Lighnting Protection as per IEC62035The Six Interdependent Disciplines that form the ProtectionPlan are:
Capture the lightning strike
Convey this energy to ground
Dissipate the energy into the grounding system
Bond all ground points together
Protect incoming AC power feeders with use of Surge Protection
Protect low-voltage data/telecommunications circuits with use of Surge Protection
The lightning protection materials to be used for this type of installation may be aluminum or copper, within the allowances of NFPA® code 780. Some of the criteria for choosing one type of material over another are as follows:
Materials to which lightning protection components are to be installed for compatibility; aluminum on aluminum, copper on copper, etc.and Other Lightning protection components to match existing lightning protection materials.Lightning protection components to match existing lightning protection materials.
Installations where lightning protection is highly desirable aresummarized as follows:
Power stations Thermal ,Hydero Power Wind Power and Solar PV
Sub-stations and transformer stations
Oil and gas storage and refinery
Grain storage
Explosives factories and storage areas
Flammable liquid or chemical storage
Factories such as chemical, textile, rubber, sugar, glass, paint, etc.
Mining areas
Television, radio and telecommunications stations
High rise buildings - commercial and apartment complexes
Hospitals
Transport - airports, shipping, rail etc.
Universities, education facilities
Historic structures
Churches, Mosques, etc.
Military installations
Golf courses, race courses, sports stadiums, etc.
Farms and food storage areas
Buildings containing computers and electronics

I should Design Electrical Installation to Perform My Equipment and Safety of Mine and Other’s from Electrical Shocks
Earthing Design is Not a BOQ It’s Design New Every Installation Depend on Soil Report
Earthing Value should be Achive and Maintained 24X7 365Days
Earthing should be Eqavapotentail but use Spark Gap for Insolation

Earthing and Conductor Installation
Earth electrodes (under ground) and earthing conductors (above ground) must conform to specific minimum dimensions regarding mechanical stability and possible corrosion resistance
Recommdation for Joints or Tapping any Metal ,Cables or Conductor’s Open or in Burried Environments to Avoid Rusting , Corosen Result Loose Contact ,Spark,Disconnect of Fire Accidents
below information abstarct from NBC2016,IEEE80,IEC62305 and other International Electrical Safety Installation Guide Line
Any metals ,Conductors use for extention mostly for Earthing only recommended same material for Tapping or Jointing Nut Bolt , brazing for burried connection is BAN advise to use Exothermic.
if we do with nout and Bolting , Brazing the surface contact of both material will not be 100% Result Heat when load and Sink when connection Cool later experinced Loose Contact result Spark ,Disconnect or may be Fire Accidents.
If you use different Metal for Extention and Tapping it’s very difficult to ensure 100% Surface Contact over period of Life becuase of diffirent behavior of Temperature and develop gelvanis between two Joints.
another failure rusting Conductors not capable to handle load
for Long Distance Connection we should use Soft Round Conductor advantage less Joints, angle bend while routing maintain low contact resistance result long life and high productivity.
Copper Claded Steel
Copper Claded Aluminium
Steel Round Conductors
These Conductors now recommended for Earthing Extention and Down Conductor for Lighting Discharge from Building ot Structure allow routing and bending avoid Sharp Corner Develope (which we facing with Flat Strip GI or Copper Via routing)another benifit of round conductor over Flat Strip under burried condition is long Life and faster handling any Surge or Ligthing to protect our equipment’s.

Neutral Earthing ResistorsNeutral Earthing Resistors (NERs) are used in an AC distribution networks to limit transient overvoltage's that flow through the neutral point of a transformer or generator to a safe value during a fault event such as a phase to phase, phase to neutral or phase to earth fault.
Generally connected between ground and neutral of a transformer or generator, NERs reduce the fault current to a pre-determined maximum level such that damage to equipment or network shutdown is avoided while allowing a sufficient amount of fault current to activate protection devices. A fast response time allows protection relays and current transformers to operate and quickly identify, isolate and clear the fault. Subsequent faults are also avoided. Damage to equipment is therefore minimized and the risk of hazardous arc flash is reduced or eliminated.
NER must absorb and dissipate a huge amount of energy during a fault without exceeding temperature limitations, the design and selection of an NER is critical to ensure equipment and personnel safety as well as continuity of supply.
Earthing Value can be Monitor with Alarm Alert Systemcalculating the loop resistance, G-CHECK checks the impedance of the actual path of an indirect contact leakage, for detecting the following possible incidents, both within the installation and in the transformation
centre to which it is connected:- Deterioration of the ground connection due to aging of the earth rods, theft of the cables or increasing soil resistivity in dry seasons.
- Breakage or bad connection of the neutral wire.
