NFPA 780 mandates that each lightning protection down conductor shall terminate at a ground terminal dedicated to the lightning protection systems.
Earthing Grounding Rod Lightning Protection SystemThe Chem-Rod grounding rod solves problems found with conventional grounding rods by requiring less real estate and fewer electrodes to meet specified resistance. Each Chem-Rod creates an optimal electrical connection to earth with a large conductive surface for enhanced grounding rod lightning protection.

BackgroundPublicationsReviewsVersionsMembershipCertificationsSafetyEquipmentPurposeComponentsConstructionAdvantagesIntroductionCauseBenefitsFutureFunctionThe conductor system component of complete lightning protection includes main sized cables, the structural steel of a building, and bonding or interconnection wires to internal grounded building systems. The main conductors perform the current carrying function from the strike termination devices to the grounding system. Main cables are highly conductive copper or aluminum that perform well in an external environment.

Jul 21, 2017 · A lighting protection system (LPS) requires a network of electrically conductive paths to safely transmit a lightning strikes 300 million volts from rooftop air terminalscolloquially called lightning rodsto ground electrodes. Air terminals rise 10 inches or more above a building to intercept lightning before it reaches the structure.

When structural steel is used as a lightning down conductor what must be connected near the base of the column High Sandy or gravelly soil conditions are generally characterized by - soil resistivity therefore multiple grounding electrodes must be used to augment the lightning ground electrode systems
Method statement for Installation & Testing of Earthing Field testing of Earthing and Lightning Protection System. Grounding rods shall be tested for ground resistance value before any wire is connected. The test shall be performed in normal dry weather, not less than 48 hours after rainfall. Ground resistance shall also be measured for each piece of equipment to the ground electrode.
Structural Earthing and Lightning protection systems for In order to establish equipotential bonding in lightning protection systems and for EMC purposes, steel rods or strips must be laid in the foundations and connected to the reinforcements and the equipotential bonding bar. In the event of a lightning strike, sparks may not jump through the insulation from the foundation to the earthing system.
