I have noticed a spherical piece of equipment that is attached to the upper lightning arrestor lines of 3-phase transmission line systems. Usually, they are orange and attached directly to the lightning arrestor lines (the line passes directly through the sphere).
*** So, what are these things? How do they work?
Sorry, if I can't think of a formal name for these devices, but I do want to learn more about them (and as much as I can about power systems in general). Thanks!
