Requirements for lightning protection grounding
Thread Content
When using the structural rebar in the reinforced concrete of buildings as a lightning protection network, why is it necessary to combine the grounding of the electrical system with the lightning protection grounding? In other words, why use a common grounding method? Everyone, share your thoughts!
According to the interpretation of the \"Code for Design of Static Electricity Grounding\": 3.6.1 In the engineering design of petrochemical industries, many grounding systems need to be designed, such as those for lightning protection, electrical protection, static electricity prevention, and stray current prevention. It is more appropriate for these grounding systems to use a common ground. From the perspective of electrical safety, the most economical and practical grounding measure is common grounding through a common equipotential connection. When planning the layout of grounding main lines for electrical engineering, it is necessary to coordinate with other disciplines to ensure a comprehensive approach.
I have the \"Code for Design of Static Grounding in Petrochemical Industries SH-3097\" here, but I don’t know how to upload it. Below, I copy the reply for reference.
In addition to complying with the requirements of the \"Code for Design of Static Electricity Grounding,\" lightning protection grounding must be inspected annually by a qualified organization, which shall then issue a relevant report. Additionally, the company itself must also conduct regular inspections of the lightning protection and grounding systems.
