Lightning protection grounding of primary power distribution box at construction site

Lightning protection grounding of primary power distribution box at construction site

Complete IEC 62305 lightning protection guide covering risk assessment (Part 2), LPS classes I-IV, rolling sphere method, down conductors, air termination, and SPD selection. This section applies to grounding of transmission and distribution lines and equipment for the purpose of protecting employees. Experience of lightning has shown that significant structural damage and failure / destruction of electrical systems can be caused - with the additional. Core idea: Lightning protection gives lightning current a controlled path from the strike point to earth instead of letting it travel through random building, electrical, or equipment paths. This helps to reduce the potential difference that exists between conductive parts and the earth. Equipment Protection: Grounding protects substation. [pdf]
