— 01 8 FURSE® EARTHING LIGHTNING PROTECTION QUALIT SOLUTIONS FOR SAFEGUARDING PEOPLE, STRUCTURES AND SERVICES In the vast majority countries, this need for earthing clearly stipulated through health and safety regulations, with implementation driven by approved standards. A good quality earthing system designed to: • Prevent risk life, removing the risk of electric shock • Protect connected electrical and electronic equipment from damage due the passage of fault, earth leakage lightning currents • Provide low impedance path earth, to ensure effective operation overcurrent protective devices the event fault • Ensure connected equipment remains the same electrical potential • Remove risk overheating conductors under fault conditions there risk of insulation breakdown • Ensure people near substations are not at risk from step, touch transfer potentials It essential for safety and business continuity. Designed earthing systems utilise our high quality copper earthing tapes, our earth rods, backfills, mechanical clamps and FurseWELD® exothermic welding system, ensure safe and long term earthing installation. Earthing design Power earthing design, especially for high voltage installations such substations, a complex process requiring assessment and understanding local soil conditions, existing overhead/underground conductors and metalwork, and prospective earth fault current duration and magnitude the installation.— 01 Threaded copperbond earth rods. These standards cover wide range situations, including earthing and equipotential bonding of: • Lightning protection systems • Low voltage electrical systems • Telecommunications systems • High voltage electrical systems (over kVac) Earthing essentially the connection the electrical system and connected electrical equipment, well the structural lightning protection system (where installed), to the general mass earth using suitably sized conductor. . Equipotential bonding the interconnection of all metalwork structure ensure, the event current passing earth, there no risk arcing electric shock hazard. Poor quality earthing not only risks damage and downtime equipment, but also the risk of electrocution and loss life. Our technical team provides consultancy such projects and undertakes high voltage earthing design using CDEGS software. — Introduction Earthing Earthing the lightning protection system, well the electrical installation, is paramount for safety, protect life, electrical equipment and critical electronics from electrical system faults and lightning currents
