Search through Australian (AS1768) or British standards on lightning protection and you will find answers as to what the sphere method is and how to apply it. Basically the rolling sphere method is a means of determining the area which will be protected by a lightning air terminal (Lightning rod) and thus a means of determining how many air terminals are required and where they need to be placed in order to protect a given area from lightning strike.
