Best Earthing Practice to perform equipment well & protects from shock (As per Latest NBC-2016) 1. Equipment Earthing  
CI/GI/ Copper Plate earthing with maintenance material Copper/ Copper Bonded Steel Rod with maintenance free earthing system
2. GRID Earthing
Copper Bonded Steel Rod- Best Earthing Material / Superior in Quality / Recommended by IEEE 80, UL 467, IEC 62561-2, IS 3043
• Low carbon solid steel rod with minimum 250 micron pure copper coating as per UL 467 • Offers 4 to 5 times more working life than GI electrode • Excellent fault current carrying capacity • Exhibits same corrosion resistant property as copper • High strength of steel • A cost effective solution • Theft proof solution
Complete Earthing Arrangement
The use of Earth Enhancing Compound complying to …IEC - ……..pla s a i porta t i making grounding system much more effective. - It retain moisture thus provide smooth path for current to flow faster. - Si e it has oisture rete tio properties it does ’t de a d regular watering that makes the grounding system low maintenance. - The continuous presence of moisture provides stable Ohmic value. - It does ’t ot ashes a a ith ti e. - It does not demand continuous presence of water to maintain its conductivity.
Fire Accident due to electrical joint failure in Lightning Protection & Earthing
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.
Earthing Connections & Joint Practices
For making earthing connections & electrical jointing, mechanical joints are still prevails. Nut & Bolt, welding, clamping, brazing Only give 8-20% contact surface area
Gets corroded over the period of time due to atmospheric corrosion Contact areas of connections have voids and gaps which cause corrosion, rust and oxide results in early deterioration
Resistance of mechanical connections increases with time and this alters the conductive properties of connections
EXOTHERMIC WELDING- For all buried & permanent connections as per IEEE 837 / NBC 2017 Main earthing wire connections shall be: • Be mechanically & electrically sound; • Be protected against damage, corrosion and vibration; • 100% contact surface area is must; • Be secured at the earth electrode;
EXOTHERMIC WELDINGPermanent Jointing solution These cavity can be designed on customize basis as per the type of joint is required.
Also the dimension of the conductors which needs to be joint in a kind of jointing. We are the manufacturer and can offer any kind of joint type as mentioned below:

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

Lightning Risk Assessment Study is actually the measure of risk of a lightning strike and probability of damages. As Per IEC62305-2. All these calculations are based on: Lightning strike density in that particular area(provided byOMV i.e.Ng = 8), Danger for people, Occupation coefficient of structure, Relative location of site, Fire Risk, Associated services, Electrical Lines, Lightning Protection Level, Surge Arrestor and Dimensions of installation.

Lightning Protection As Per NF C 17 102/UNE 211186
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 (Δt in ¾s), 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 60¾s). The NFC 17-102/UNE 211186 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.
Early Streamer Emission Air Terminal
•An active and advance technology device based on the principle of Corona effect. •Internationally accepted technology complying standard NFC 17-102. •Active Protection not only protects the structure also protect surroundings & open areas. •Made up of stainless steel SS-316L hence highly corrosion resistant and long lasting. •More life due to corrosion resistant material is used. •Single installation offering maximum radius of protection of 109 meters which is very large in comparison to conventional lightning system. •ESE air terminal is very quick in response. •Excellent, no electronic device.
•Economical solution. •Easy to Install.
IEC Declaration by CENELEC for NFC17-102
BT has confirmed that ESE National Standards would remain valid and thus BT recognized there ould e o e ide e of o fli t et ee NF C ‐ a d IEC EN ‐ sta dards a d consequently there is no reason, technical or otherwise, for the withdrawal of the respective national standard.BT has requested that this standard be modified in order to cancel all refere e to the IEC EN ‐ series, allowing the NF C ‐ sta dard to e ist, ith the proposal of possible future migration to international level (lEC). Accordingly, it was established that European ESE standards (France, Spain, Portugal, Slovaquia, etc.) will not conflict with other European standards and will remain valid.
• GIMELEC would draw your attention to the fact that the ter s of refere e of NF C ‐ a d • other standards, addressing alternative terminals (NF C ‐ , PR EN ‐ ‐ ) ere fro the • outset, er differe t. It is a fa t that NF C ‐ , whilst referring to ESE Technology also • comments on other standards for lightning protection systems, particularly incorporating • faraday cage, franklin rod and catenary wire systems. the 'camouflaging' of NF C ‐102 by IEC EN • ‐ and its proponents, that FRENCH STANDARD NF C ‐ is still in full force.
