Is there some way to perform IEC-62305 rolling sphere lightning rod analysis without the use of software? There must be some method that people used when there were no computers.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Rolling Sphere Lightning Rod
IEC 62305-1 Table 6 the minimum peak current and the rolling sphere radius according to LPL class.
The Rrolling=10*I^0.65 m [I[kA].
You may check the rolling spheres contain no equipment [or other element] on a drawing [or sketch].
