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

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.
