[ d \leq \sqrtr^2 - (h - r)^2 - \sqrtr^2 - (H - r)^2 ]
For decades, the protection of structures against direct lightning strikes has relied on a few key geometric models. Among them, the stands out as the most intuitive and physically accurate representation of how lightning intercepts a structure. Unlike the older "cone of protection" method, RSM accounts for the actual striking distance of lightning, making it indispensable for protecting complex or sensitive facilities like substations, data centers, petrochemical plants, and tall buildings. rolling sphere method calculator
