Introduction: The electrical connection of all exposed conductive parts and extraneous conductive parts to maintain substantially equal potential is called equipotential bonding. The potential equalization between all surfaces which are thus bonded. Exposed conductive part: Noncurrent carrying conductor in equipment which can be touched and not a live conductor and…

Introduction: The main and most effective measure for protection of structures against physical damage is considered to be the lightning protection system (LPS). The components of LPS are more prone to direct lightning strikes and corrosion due to local environment. Hence proper inspection and maintenance should be carried out periodically…

Earth-termination systems should perform the following tasks: Conduction of the lightning current into the earth; Equipotential bonding between the down-conductors; • Potential control in the vicinity of conductive building walls. Foundation earthing meets all the above requirements. For large structures and industrial plants the foundation is normally reinforced. …

Article on “ Natural Component as a LPS Conductor” Metallic Roofing: LPS conductors and rods should be mechanically secured so that they are capable of withstanding stress due to wind or weather and work carried out on the roof surface. Metal covering provided for mechanical protection of outer walls parapet…

“Earth Enhancing Compound” Earth enhancing compounds (EEC) or Back filling compounds (BFC) are highly conductive compounds which are filled around the earth electrode by replacing the existing high resistance soil to provide low earth resistance value and improve the performance of earthing system. Why do we need EEC/BFC? In areas with soils of…

ESE Air Terminal Rod is an active type lightning arrester which stimulates continuous upward leader before any other object does within its radius of protection. Due to its earlier triggering of upward leader, the area of protection is much larger when compared to a simple conventional air terminal rods. The…

The components of Lightning Protection System (LPS) are exposed to direct lightning strikes and corrosive atmosphere. To achieve efficiency, the materials should have high current withstanding capacity and the materials should be less corrosive. …

Current Carrying Capacity Of Different Materials The Earth electrodes should be designed to withstand the fault current without any physical damages. The fault current carrying capacity of a material mainly depends on cross sectional area of that particular material. …

Introduction: Taller buildings in general attract lightning strikes, hence an efficiently designed LPS is highly critical to safeguarding these structures from the destruction caused due to lightning. Also, such structures should make sure quality earthing systems and surge protection devices are installed to protect the lives and expensive electronic equipment housed…
