Maintenance-Free Earthing: Your Guide to Safe, Reliable Grounding Did you know that faulty electrical earthing causes a shocking number of accidents each year? Earthing's main job is to protect people and equipment from electrical dangers. Maintenance-free earthing is a modern solution to this safety need! Let's explore why it beats old-fashioned methods. Understanding Traditional Earthing Systems Let's examine how typical earthing works and its parts. Components of Traditional Earthing Old-school earthing uses several parts. Earth electrodes, like rods or plates, go in the ground. Connecting conductors link the electrical system to these electrodes. Also, earth pits house the connections, protecting them. How Traditional Earthing Works Traditional earthing gives fault current a path to the ground. When a fault happens, the current travels through the conductor to the earth electrode. Impedance, or resistance, plays a role in how well this works. Lower impedance means better protection. Limitations of Traditional Earthing Systems Traditional earthing has problems. For instance, corrosion can damage electrodes and connections. Soil resistivity, or how well soil conducts, changes with moisture. This causes big problems. This means regular checks and pouring water into the earth pit are needed. These systems need constant upkeep. The Evolution to Maintenance-Free Earthing Advancements in materials and design have created maintenance-free earthing. This system offers better reliability and less hassle. Material Innovations New materials are key. Copper-bonded steel resists corrosion better than plain steel. Graphite compounds improve conductivity and electrode lifespan. These materials make maintenance easier. Design Improvements Sealed systems are a smart design change. These prevent moisture and contaminants from reaching the electrode. Special backfill compounds around the electrode keep soil resistivity stable. These design choices cut down on maintenance. Addressing the Challenges of Traditional Earthing Maintenance-free systems fix the flaws of older methods. For instance, corrosion-resistant materials reduce the need for replacements. Stable soil conditions mean performance stays consistent. These changes make earthing more effective. Benefits of Maintenance-Free Earthing Maintenance-free earthing brings lots of good things. It saves money and improves safety! Reduced Maintenance Costs Think about the long-term costs. Traditional systems need regular checks and repairs. Maintenance-free systems cut these expenses. Over time, you save a lot of money! Increased Reliability and Safety Consistent performance matters. Maintenance-free earthing reduces the risk of electrical hazards. Because of this, facilities are safer. This reliability is invaluable. Environmental Advantages These systems help the planet, too. They use less water than older systems. Also, they often use eco-friendly materials. This makes them a greener choice. Implementing Maintenance-Free Earthing Here's how to get maintenance-free earthing up and running. Selecting the Right System Pick the right system for your needs. Think about soil conditions, fault current levels, and industry standards. A good choice ensures optimal safety. Installation Best Practices Follow best practices during installation. Place electrodes properly and make secure connections. Use the right backfilling techniques. Correct installation is key. Testing and Commissioning Test the system after installation. Verify it works as expected. Then, check it regularly to ensure it stays effective. Regular checks ensure long-term safety. Common Misconceptions About Maintenance-Free Earthing Let's clear up some common confusions. Myth: "Maintenance-Free Means No Inspection" Maintenance-free doesn't mean "never look at it." Visual inspections are still a good idea. Look for any signs of damage or wear. Early detection prevents future problems. Myth: "Maintenance-Free Systems Are Too Expensive" The initial cost might seem higher. However, consider the long-term savings from reduced maintenance. Maintenance-free systems can be a cost-effective solution. Myth: "They Are Not Suitable for All Soil Conditions" Different maintenance-free solutions exist for various soil types. Work with experts to find the right fit for your situation. There is a system for you. Conclusion Maintenance-free earthing gives us great benefits. Lower costs, more safety, and less environmental impact. Remember proper installation and periodic checks are still critical! Consider switching to maintenance-free earthing for a safer, more reliable electrical setup.

During thunderstorms too, high volume of energy is instantaneously released which is more common in nature. The most important aspect of understanding in lightning protection is that – not only a direct lightning strike act as a potential threat to the structure but also more frequently, electronic equipment are damaged by surges caused by remote lightning discharges (caused because of Lightning Electromagnetic Impulses or LEMPs) or switching operations in larger electrical systems. The international standard for Lightning Protection referred as IEC 62305 – ‘Protection against Lightning’, (which is also accepted by many countries as national standard) especially adopted by Bureau of Indian standard as IS IEC 62305, in one of its part explains the need of planning, erection, testing and maintenance of lightning protection systems for building structures without any height limit. The same is also implemented in new National Building Code – 2016, Part -8, Section 2 which also clearly defines the need of the measures to be taken care for planning, erection, testing and maintenance of lightning protection system. A proper lightning protection system (consisting of air terminal, down conductor, earthing) design is very important to ensure increased protection of a building against lightning and its effects. Systems followed in most of the buildings now are unfortunately not meeting the basic or statutory requirements. Since only a mere vertical air terminal will not solve the purpose for protection of building unless the entire building is sufficiently protected either with: • Angle of protection method • Mesh conductor method or • Calculated as per rolling sphere method. Effective lightning protection measures Proper measures are to be taken care of while designing, procuring and installing of lighting protection components for handling a strike and dissipation of current without any dangerous spark overs. For buildings are surrounded by trees, or a taller metallic tower the protection measures should include not only lightning protection but also required ring earthing around the building and Surge protection for the equipment since the fatality due to lighting could be more disastrous for an equipment than a structural damage. Periodic maintenance, monitoring and certification should be made mandatory for the effective functioning of the protective devices installed. For protection of electrical, wiring, electrical and electronic equipment, installation of Surge Protection Devices should be adopted. Lightning protection is often a challenge for the building designer when it comes to aesthetics of the building. Routing of down conductors through outer wall generally spoil the aesthetics of the building, due to which the down conductors are often routed through shafts, un-accessible areas, non-visible places etc. These down conductor increases the chance of fire and explosion in case of lightning. As a statutory requirement Lightning Protection is implemented in most of the buildings, but unfortunately in an inefficient way. Lightning flashes to, or nearby, structures (or lines connected to the structures) are hazardous to people, to the structures themselves, their contents and installations need to be considered for protection measures. An effective lightning protection is achieved only if the following points are adhered viz., » Type of protection » Level of protection based on risk assessment » Technically qualified product as per latest and relevant IEC standards » Sizes and dimensions of components » Location of air terminal and coverage » Conductor routing and connections » Sufficient and required earthing provisions » Proper utilisation natural components as down conductor if applicable. Design guidelines The following design guidelines need to be adhered to ensure safer installation of the external LPS. » A down-conductor should be installed at each exposed corner of the structure where this is possible. » The down-conductors should form a direct continuation of the air-termination conductors » Straight and vertical so that they provide the shortest and most direct path to earth » The formation of loops in bring the down conductor shall be avoided, but where this is not possible the distance ‘s’ shall be maintained. » Connection of down conductors to gutters or down-spouts even if they are covered by insulating materials. » Usage of multiple connection with different materials should not be permitted. » Insufficient conductor dimensions (non-complying material as mentioned in IEC 62305-3 Table – 5) should be strictly avoided. » When the distance from down conductors to combustible materials cannot be assured, the cross section of the down conductor shall not be less than 100 sq.mm. » The electrical insulation between the air-termination or down-conductors and the structural metal parts, the metal installations and the internal systems can be achieved by providing a distance ‘d’ between the parts greater than the separation distance ‘s’. ‘S’ = (Ki) x {Kc/Km} x L Where: Ki -depends on the selected class of LPS Kc – depends on the lightning current flowing on the down conductors Km – depends on the electrical insulation material L – length in meters along the air-termination or down-conductor, from the point where the separation distance is to be considered, to the nearest EPB point. Depending upon the nature of LPS system and area to be protected the number of air termination will be decided. The maximum distance of any point on the roof from the nearest horizontal protective conductor shall be decided as per nature of LPS system and the level of protection. Horizontal conductors in form of a mesh conductor. The mesh spacing of the horizontal conductor should depend on the class of LPS as per tabulation of IEC 62305 Part 3 for mesh spacing. Conclusion The most neglected part in many structures or buildings are protection against lightning. Since the post impact of lightning is too severe and disastrous care should be given at every level to ensure lightning protection is not provided for seeking statutory approvals. The installation should not be a vendor driven and only based on regulations as insisted by national or international standards and code. All maintenance procedures shall be scheduled and carried out meeting the standard requirements in periodic intervals. Last but not the least, human safety from lightning will only be possible by creating awareness, use of warning signage boards in required location and not by any protective devices.
