Importance and Design Requirements of Equipotential Connection in Lightning Protection Engineering

The role played by equipotential connection in lightning protection was summarized in terms of lightning protection, static electricity, electromagnetic shielding, protection from electric shocks, and earth fault protection. In addition, drawbacks of independent grounding and common grounding were concluded. According to standards and researches, such as Building Lightning Protection Design Standard (GB50057-2010), further demands and rules of equipotential connection in lightning protection engineering were proposed, providing references for lightning prevention design, construction and examination by related scientific workers and staffs.
