There is a lot of energy moving through the air before and during a lightning strike. The lightening itself is the locus of energy that is dense enough to cause massive amounts of heat. Lighting rods are there to protect against fire-causing heat. But there is a lot of lower intensity energy flowing around it can induce currents in any conductor. You have to shield conductors to prevent local power surges.
Our lab had a source of "conditioned power" that was supplied by batteries and shielded from EMP and atmospheric energy. I doubt that it was cheap but it kept extremely sensitive equipment like strain gauge amplifiers working in the worst storms.
